- the emitted wave spectrum may be that of a xenon lamp.
- the battery or the accumulator may be designed to be recharged by the user by means of induction.
- a light-curable material will be understood to mean a material, for example an adhesive, the viscosity of which is deliberately increased in the context of curing only when irradiated with light. The increase in viscosity is very pronounced. The increase in viscosity may lead to a transition from the liquid or viscous state to the solid or sliceable state.
- the light-curable material may be an acrylic-based material, a material containing acrylic components, or an acrylic adhesive. Examples of a possible, suitable light-curable material are “Vitralit® 9180 VL” and “Vitralit® 9188 VL” from the company Panacol-Elosol GmbH located in Steinbach, Germany.
- a light-curable material will be understood to mean a photo-inducible material.

- the flashlight device according to the invention has a protection unit. This is provided and arranged so as to protect the eyes of the user of the flashlight device against any entry of flashlight, or in any case to reduce the risk thereof. In this way, at least an unpleasant dazzling of the user by the curing by means of light can be prevented or reduced.
- the protection unit is attached to the light guide. This may advantageously help to ensure that, when the light guide is replaced with another light guide, the protection unit is also exchanged. It is thus easy, without any additional effort, advantageously to replace both the light guide and the protection unit together.
- the user can thus advantageously have in each case a light guide that is more suited to the specific intended use.
- the light guide of the flashlight device according to the invention has at least one flexible section. Different emission directions of the generated light or flashlight can thus be set or achieved.
- the light guide of the flashlight device according to the invention is flexible such that it can be deformed by hand, but at the same time is stiff so that it remains in this deformation after it has been deformed.

- the press-switch can thus automatically return to the off position.
- the flashlight device has a unit by means of which the light emission can be initiated or triggered or started wirelessly. This can enable working with the flashlight device even from a certain distance. Moreover, in this embodiment, “hands-free” working may advantageously be possible.

- the unit for generating flashlight is suitable and intended for generating a voltage in a range from 400 to 500 Volts.
- said flashlight device has a unit by which it can be attached to the user thereof.
- the attachment unit may be a head mount. It may be or comprise a headband, which may be flexible or rigid, for example as part of a helmet or a section thereof.
- the use of such an attachment unit advantageously enables the user of the flashlight device to keep his hands free, but at least enables him not to have to hold the flashlight device with one hand during the curing of the light-curable material.

- the method according to the invention can also be carried out with light guides that have already been introduced beforehand.
- the light guide is configured as one or more optical fibers.
- the use of light guides introduced or to be introduced in this way may advantageously help to bring light, which is required for curing purposes, by means of the light guide, to locations at which otherwise no light or insufficient light would fall for curing or completely curing the light-curable material.
- Such locations may accordingly be located far away from the point where the light exits from the flashlight device, for which reason the light intensity available for curing purposes is not sufficient for the desired curing.

- the method according to the invention relates to the use of a light-curable material for gluing or bonding or modeling, in particular in the industrial sector or in the non-commercial sector.
- a flashlight device according to the invention or an LED lamp is used for curing purposes.
- the LED lamp may emit predominantly or exclusively light having a wavelength of 405 nm. In this case, the light may have this wavelength due to the nature of the LED lighting element and/or due to a light filter that is optionally used.

- the use of the method according to the invention differs from known methods and from the “conventional” adhesive systems of the prior art inter alia in that, according to the invention, there is no need to wait for the “adhesive” material used, that is to say the light-curable material, to cure. The bonding effect of the light-curable material is obtained virtually immediately.
- bonding can take place in a time-saving manner by means of the method according to the invention.
- These parts and elements can be placed in position and, once the position has been checked, are fixed to one another by targeted illumination.
- the fixing takes place at the moment of curing. This may take place within a fraction of a second.
- a primary fixing of elements can thus be achieved in the blink of an eye.
- a primary fixing is achieved after just 300-500 ms.
- the curing process is complete after approximately 5-8 s. Any subsequent reinforcements of the bonding sites can be taken care of without any time pressure.
- the method according to the invention can be carried out without hesitation in rented homes and holiday homes, exhibitions and trade fairs and the like.
- the cured adhesive can be removed without leaving any residue.
- the method according to the invention can be used in crafts and model-making as well as in architecture, planning and engineering offices, in electronics and medical technology and even applications in the hobby and household sector.
- a high viscosity of the light-curable material means a sufficient stability. This property, paired with the single moment of curing, offers the possibility of creating or building objects in layers.
- the light-curable material used can optionally be post-processed by milling and polishing.
- any objects such as jewelry, decorative articles, art, etc. can advantageously be duplicated.
- the latter can be cured within the mold by the flashlight device according to the invention or by the LED standard lamp. Once the solid material has been removed from the mold, it can if necessary be briefly illuminated again from all sides. If desired, the finished “clone” can be subsequently worked on using tools.
- the bonds achieved may be reversible.
- the light-curable material used can be removed without leaving any residue and does not attack the surfaces of the objects.
- the method according to the invention is therefore also highly suitable for the three-dimensional printing of objects or for constructing objects in some other way from the light-curable material used or for the additional processing thereof.
- the light-curable material can easily be applied by holding and operating the device with one hand.
- the applied material can then be cured by means of the LED lamp on the opposite end face of the device.
- the sequence of activities, applying and then, after rotating the device, curing advantageously prevents the light-curable material from running out of the device even when no closure cap has been placed on a discharge opening of the reservoir. Said closure cap is not necessary during this handling, which can make it very easy and pleasant to work with the device according to the invention. Overall, the device is easy and safe to handle.
- One possible use example of the present invention is the gluing-on of artificial fingernails, as is known in a nail studio.
- the present invention can in this case advantageously contribute to a considerable time saving.
- Another use example of the present invention is the gluing, repairing, attachment, etc. of objects such as tiles, fixings or the like, which are present in a liquid.
- a crack in a tile can be fixed by means of the method according to the invention using the light-curable material under water and thus in the wet.
- the invention there is no need to leave the water in order then to close the crack in a dry environment. This advantageously makes it possible to make a saving in terms of effort and costs in connection with work carried out on objects located underwater for example, such as the hull of a ship.

The International Application was published in German on Apr. 5, 2012 as WO 2012/041510 A2 under PCT Article 21(2).
- The present invention relates to a flashlight device for curing light-curable materials, to a method of use thereof, and to a set.
- Light-curable acrylic adhesives for use in the oral cavity are known from the dentistry sector. These adhesives are used primarily to produce temporary restorations. After they have been applied, they are cured by irradiation with UV light from UV lamps.
- One object of the present invention is to propose a further light device and corresponding methods and a set.
- This object is achieved by a set for at least one of gluing, bonding, modeling and repairing of an object. The set includes a housing comprising a first end, a second end, and a reservoir, a light-curable material arranged in the reservoir, and a lamp configured to emit a light having a wavelength or a spectrum of wavelengths at which the light-curable material is selectively cured and to be coupled to the housing at the second end so that the light emitted by the lamp is only emitted in a direction which faces away from the first end. The reservoir comprises an exit opening which is configured to selectively discharge the light-curable material at the first end. The housing is completely impermeable to light.
- The present invention is described in greater detail below on the basis of embodiments and of the drawings in which:
-
FIG. 1 schematically shows, in simplified form, a device according to the present invention in a perspective view; -
FIG. 2 shows a section through the device according to the present invention as shown inFIG. 1 ; -
FIG. 3 shows a further device according to the present invention in the form of a hook; -
FIG. 4 shows a flashlight device according to the present invention for curing the light-curable material, in the form of a lamp/magnifying glass combination; -
FIG. 5 shows a further device according to the present invention having a reservoir for the light-curable material and an LED lamp; and -
FIG. 6 shows the device ofFIG. 5 in one possible use. - In all the embodiments below, the use of the expression “may be” or “may have,” etc. is to be understood to be synonymous with “preferably is” or “preferably has.”
- According to the invention, therefore, a flashlight device is proposed which comprises at least one unit for generating flashlight and at least one unit for focusing the generated flashlight.
- Advantageous further developments of the present invention form the subject matter of dependent claims, the description below and the examples of embodiments.
- In some embodiments according to the invention, a flashlight device will be understood to mean a gas discharge device for generating light. In some embodiments according to the invention, the flashlight device is provided with a capacitor which is supplied by means of a battery or an accumulator. In some embodiments according to the invention, the flashlight device is configured as a xenon gas discharge device or as a discharge device comprising another noble gas. The emitted wave spectrum may be that of a xenon lamp.
- The battery or the accumulator may be designed to be recharged by the user by means of induction.
- In some embodiments according to the invention, a light-curable material will be understood to mean a material, for example an adhesive, the viscosity of which is deliberately increased in the context of curing only when irradiated with light. The increase in viscosity is very pronounced. The increase in viscosity may lead to a transition from the liquid or viscous state to the solid or sliceable state. The light-curable material may be an acrylic-based material, a material containing acrylic components, or an acrylic adhesive. Examples of a possible, suitable light-curable material are “Vitralit® 9180 VL” and “Vitralit® 9188 VL” from the company Panacol-Elosol GmbH located in Steinbach, Germany. In some embodiments according to the invention, a light-curable material will be understood to mean a photo-inducible material.
- In some embodiments according to the invention, a focusing of light will be understood to mean a bundling or concentration of the exiting light energy or of significant portions thereof. The bundling or concentration may be such that the light energy or light quanta exiting from the flashlight device or generated by the latter are directed in a targeted manner onto a spot or a surface area. The surface area may have a size of 3×3 cm, 2×2 cm, 1×1 cm, 5×5 cm, intermediate ranges and combinations of the numerical values and ranges specified here.
- In some inventive embodiments of the flashlight device, the focusing unit has or is designed as a light guide or an optical fiber. The light guide may be made of a transparent, light-permeable material, such as glass or plastic, or may comprise such a material. The light guide may be an optical fiber.
- In some embodiments according to the invention, a light guide is or comprises one, several or many glass fibers, polymeric optical fibers or other light-guiding components, for example made from plastic or fiberoptic components.
- The light guide may be configured as a gradient index fiber or a step index fiber or in each case as a plurality thereof.
- The light guide may be curved or straight. The light guide may have a sheath to prevent light from exiting at a location other than the desired location.
- The housing of the flashlight device may have, in a main section thereof, in particular therefore without taking account of the light guide, the form of a laser pointer or a pocket torch.
- In some embodiments according to the invention, the flashlight device according to the invention has a protection unit. This is provided and arranged so as to protect the eyes of the user of the flashlight device against any entry of flashlight, or in any case to reduce the risk thereof. In this way, at least an unpleasant dazzling of the user by the curing by means of light can be prevented or reduced. In some embodiments according to the invention, the protection unit is attached to the light guide. This may advantageously help to ensure that, when the light guide is replaced with another light guide, the protection unit is also exchanged. It is thus easy, without any additional effort, advantageously to replace both the light guide and the protection unit together.
- If different light guides are provided, as is the case in some inventive embodiments of the flashlight device, the user can thus advantageously have in each case a light guide that is more suited to the specific intended use.
- In some embodiments according to the invention, the light guide of the flashlight device according to the invention has at least one flexible section. Different emission directions of the generated light or flashlight can thus be set or achieved.
- To this end, it may be particularly advantageous if the light guide of the flashlight device according to the invention is flexible such that it can be deformed by hand, but at the same time is stiff so that it remains in this deformation after it has been deformed. This should apply at least to a range of possible deformations. According to the invention, it is not necessary that the light guide can retain its shape after every conceivable deformation.
- In some embodiments, the flashlight device according to the invention has the form of a pen or writing instrument in general, in particular one that is commercially available.
- In some embodiments according to the invention, the flashlight device has a press-switch for switching on the flashlight by applying pressure thereto.
- In some embodiments according to the invention, the press-switch is designed so as, when the pressure by which the flashlight has been switched on is ended, to move automatically from the on position, in which the flashlight is lit, to an off position, in which the flashlight is not lit. The press-switch can thus automatically return to the off position. In this embodiment, it may advantageously be possible to meter more accurately than with other types of switch the quantity of light desired for curing purposes.
- In some embodiments according to the invention, the flashlight device has a unit by means of which the light emission can be initiated or triggered or started wirelessly. This can enable working with the flashlight device even from a certain distance. Moreover, in this embodiment, “hands-free” working may advantageously be possible.
- The use of a tripod for the flashlight device or of a head mount for the flashlight device for attaching the latter to the head area of the user of the flashlight device is also encompassed by some embodiments of the invention. In some embodiments, therefore, the flashlight device according to the invention may include a tripod or a head mount, by which in each case the advantages known in this connection can be achieved.
- In some embodiments according to the invention, the flashlight device has lenses, apertures or other such optical devices within a beam path for adjusting an exiting light quantity or for optical light amplification. The advantages that can be achieved with this are known to a person skilled in the art.
- In some inventive embodiments of the flashlight device, the focusing unit has or is a reflector unit.
- In some inventive embodiments of the flashlight device, said flashlight device has at least one filter or one filter attachment with a filter effect in the range from 390 to 500 nanometers (nm), in particular in the range from 450 to 480 nm, in particular at 470 nm, and in particular in a range from 400 to 410 nm, in particular at 405 nm.
- In some inventive embodiments of the flashlight device, the unit for generating flashlight is suitable and intended for generating a voltage in a range from 400 to 500 Volts.
- In certain inventive embodiments of the flashlight device, said flashlight device has a unit by which it can be attached to the user thereof. The attachment unit may be a head mount. It may be or comprise a headband, which may be flexible or rigid, for example as part of a helmet or a section thereof. The use of such an attachment unit advantageously enables the user of the flashlight device to keep his hands free, but at least enables him not to have to hold the flashlight device with one hand during the curing of the light-curable material.
- The present invention proposes a method for curing a light-curable material, which comprises using a flashlight device without a focusing unit or a flashlight device according to the invention having a focusing unit.
- The present invention proposes a method for curing a light-curable material, which comprises using light guides between a first curing or contact or adhesive section (in short: section or sections), which is to be bonded to a second curing or contact or adhesive section by means of the light-curable material, and the second curing or contact or adhesive section.
- In certain embodiments, the use is or comprises an introduction of the light guide or light guides. However, the method according to the invention can also be carried out with light guides that have already been introduced beforehand.
- In some embodiments according to the invention, the light guide is configured as one or more optical fibers.
- In certain embodiments according to the invention, the use of light guides introduced or to be introduced in this way may advantageously help to bring light, which is required for curing purposes, by means of the light guide, to locations at which otherwise no light or insufficient light would fall for curing or completely curing the light-curable material. Such locations may accordingly be located far away from the point where the light exits from the flashlight device, for which reason the light intensity available for curing purposes is not sufficient for the desired curing. However, they may also be difficult to expose to light due to a curvature or branching of the bonding region between the sections per se. Such locations may be characterized by a large layer thickness.
- In some flashlight devices according to the invention, these are part of a combination of lamp and magnifying glass. In this case, the corresponding lamp/magnifying glass combination has both a magnifying glass and a curing lamp. In addition, they may have a conventional reading or working lamp having any light spectrum, that is to say, for example, the known light spectrum. In some embodiments according to the invention, it is provided that the reading or working lamp emits no light or substantially no light that is used for curing purposes. In certain cases, therefore, it emits for example no light in the range from 390 to 405 nm, in particular no light in the range from 395 to 400 nm.
- The elements of the lamp/magnifying glass combination may be provided in such a way as to be able to be replaced individually.
- In some embodiments, the set according to the invention comprises at least one flashlight device and a quantity of light-curable material which can be cured by means of the flashlight device according to the invention. In some embodiments, therefore, the set has everything that the customer needs for bonding, gluing, modeling, constructing and the like.
- In some embodiments, the set according to invention may comprise, besides the light-curable material and the flashlight device according to the invention, an additional LED lamp. The additional LED lamp emits light of a wavelength or of a spectrum of wavelengths that is set to the wavelength(s) at which the light-curable material can be cured or can be cured particularly well.
- The purchaser of a set according to the invention in these embodiments thus has the possibility of using two lamps which can supplement one another in terms of their use and performance spectrum. This is on the one hand the flashlight device according to the invention for small material thicknesses to be cured, and on the other hand an LED-based high-power polymerization lamp having a higher power and an associated shortened curing time. The latter may be used particularly in the case of relatively large models or in the case of models having an above-average material thickness (layer thickness).
- The method according to the invention relates to the use of a light-curable material for gluing or bonding or modeling, in particular in the industrial sector or in the non-commercial sector. In some embodiments according to the invention, preferably a known flashlight device, a flashlight device according to the invention or an LED lamp is used for curing purposes. The LED lamp may emit predominantly or exclusively light having a wavelength of 405 nm. In this case, the light may have this wavelength due to the nature of the LED lighting element and/or due to a light filter that is optionally used. The emitted light may be blue, or it may be white.
- The preferred wavelength range of the light device may lie between 390 and 405, in particular between 395 and 400 nm.
- The method according to the invention relates once again to the use of a light-curable material for gluing or bonding or modeling, in particular in the industrial sector or in the non-commercial sector. For curing purposes, use is optionally made of a known flashlight device, a flashlight device according to the invention or an LED lamp or any other suitable lamp or light source.
- In some embodiments, the method according to the invention comprises introducing the light-curable material into a liquid (for example water) or below a liquid level or using light-curable material that has already been introduced into a liquid or below a liquid level. It also comprises curing the light-curable material in the liquid or below the liquid level. This includes for example, but in a non-limiting manner, the curing of the light-curable material under water. A gluing, modeling, closing of gaps, cracks, etc. using the light-curable material is encompassed for example by the method according to the invention as described here.
- According to the invention, the curing of the light-curable material may take place by means of a light source, which light source (or a section thereof such as a light exit point, for instance the end of a light guide) is located in or outside of the liquid (or below or above the liquid level). The necessary light may thus be generated outside of the liquid and introduced into the liquid. The necessary light may thus be generated within the liquid.
- In some embodiments according to the invention, a liquid will be understood to mean a liquid mixture. In some embodiments according to the invention, a liquid will be understood to mean water, for example water of a swimming pool.
- The light source may in this case be a light source according to the invention of any type, or a different light source, in particular a light source described herein.
- The device according to the invention is intended to be bonded to a structure, the device having at least one retention means or depression. The retention means or depression is intended to accommodate a quantity of light-curable material, by means of which the device can be bonded to the structure.
- The bonding takes place preferably between in each case at least one surface of the device and structure.
- The surface of the device and the surface of the structure may in this case have surfaces of different roughness.
- In some inventive embodiments of the device, one or more retention means or depressions are open to the atmosphere in a direction facing toward the structure, based on the state in which the device and the structure are bonded to one another. This opening allows light-curable material to be introduced into the retention means before being cured by light. It may also enable a bonding between the light-cured material which exists within the retention means or depression after the curing of the light-curable material and light-cured material which exists outside of the retention means and which is in double-sided contact both with the device and with the structure.
- In some inventive embodiments of the device, said device is intended to be bonded by means of a flashlight device according to the invention and/or a method according to the invention.
- In some inventive embodiments of the device, said device has at least one retention means which has or forms an undercut that is located completely or partially within the device.
- In this case, the retention means may be a through-opening in the device. It may be a blind hole. In the case of a blind hole, the opening thereof preferably faces toward the structure in the state where the device is bonded to the latter.
- The device according to the invention may be configured as a hook which is to be attached to a surface. In certain embodiments, the basic material thereof is permeable to light, in particular in a wavelength range mentioned herein.
- The device according to the invention may have, besides retention means or as an alternative thereto, perforations or blind holes which may likewise accommodate light-curable material.
- In some inventive embodiments of the device, said device is made of or comprises a first material, and is intended to be bonded by means of the light-curable material to a structure which is made of or comprises a second material. In this case, the first and the second material are different from one another. Said difference may concern in particular the surface properties thereof, and more particularly the roughness thereof. For instance, the device may be made of a smoother material or with a smoother surface than the structure or the surface thereof.
- In some embodiments according to the invention, the device is or comprises a corner protector or a protection device of any type. The device may be a corner protector or protection device for household furniture. The device according to the invention may be as a corner protector for covering corners or edges of furniture. The protective function of the device according to the invention may correspond to those corner protectors which are nowadays attached to furniture in order to protect children, with the aim of reducing the likelihood of children injuring themselves on the furniture.
- In some embodiments, the device according to the invention has at least one reservoir for a quantity of light-curable material and/or at least one light-emitting unit for curing the light-curable material.
- In some embodiments according to the invention, the at least one light-emitting unit is an LED lamp.
- In some embodiments according to the invention, the device according to the invention has a housing which is completely impermeable to light or which is impermeable to light at least in sections thereof.
- The impermeability to light may in certain embodiments be completely or substantially limited to light of a wavelength that leads to the curing of the curable material.
- In some embodiments according to the invention, the at least one reservoir is located entirely in an interior of the device.
- In certain embodiments, the housing of the device has the form of a pen, a writing instrument in general or another hand tool. The housing may have particularly ergonomic sections, for example a finger rest for the index finger and thumb. In some embodiments according to the invention, the finger rest has a slip-resistant texture when gripped by the hand. In some embodiments according to the invention, the finger rest has a surface texture in which it differs from other sections and/or from the main or largest sections of the device.
- In some embodiments according to the invention, the at least one reservoir has a volume in the range between 2 to 10 milliliters (mL), in particular in the range between 2 to 6 mL, and in particular for 4 mL.
- The reservoir preferably has an opening, through which the light-curable material can exit. The size of the opening, for example the cross-section of the opening, may be designed with a view to the metering of the reservoir volume, that is to say a small opening size for a fine metering and a larger opening for a rough metering.
- The cross-section of the opening may be round or non-round.
- The light-emitting unit may be an LED lamp. In some embodiments, this is an LED-based high-power polymerization lamp. The LED lamp may emit predominantly or exclusively light having a wavelength of 405 nm. In this case, the light may have this wavelength due to the nature of the LED lighting element and/or due to a light filter that is optionally used.
- The emitted light is blue in some embodiments according to the invention. Alternatively, it is white.
- The preferred wavelength range of the light device may lie between 390 and 405, in particular between 395 and 400 nm.
- In some embodiments according to the invention, the device has a metering mechanism for discharging light-curable material from the reservoir and/or from the device.
- In certain embodiments according to the invention, the metering mechanism is an expelling mechanism which does not or does not primarily serve for precise metering.
- In some embodiments according to the invention, the metering mechanism is designed with a displacement unit and/or a pressing unit for exerting pressure on the reservoir. In some embodiments according to the invention, the metering mechanism is designed in a similar way to a mechanism of a pen and/or has a push-button.
- In certain embodiments according to the invention, the metering mechanism is a section of the housing that is deformable or that is designed in such a way that it can be deformed. In some embodiments, the metering mechanism is designed as a deformable reservoir for discharging the light-curable material.
- In some embodiments according to the invention, the metering mechanism has at least one component which, for metering purposes, is designed to be displaceable relative to the (optionally to the rest of the) housing of the device.
- The metering mechanism may be manually controlled or manually actuated.
- A manually controlled metering mechanism may be a mechanism which releases a predefined volume by hand, for example by a pressure pulse on a piston. In a manner similar to a pipetting unit, by which different volumes can be released via the pipette by manual pressure, here a specific volume of light-curable material can be discharged by means of the metering mechanism. The specific volume may be predefined by the size of the piston, which is activated for example by a press-switch or push-button.
- The press-switch or push-button is preferably arranged on the opposite end face of the device, relative to the exit opening of the reservoir.
- A manually controlled metering mechanism may also be a mechanism which displaces a specific volume by means of a rotary movement, preferably with individual stages during the rotation. This may take place, for example, by converting a rotary movement into a translational piston movement. The piston movement may deform the reservoir and thus cause a specific quantity of light-curable material to exit.
- The manually controlled metering mechanism for rotary movement may be a rotary mechanism which is arranged as part of the housing on the opposite end face of the device relative to the reservoir opening.
- In certain embodiments according to the invention, the metering mechanism has at least one component that must be actuated for metering purposes.
- The reservoir may be arranged in the housing in such a way that, as a result of a deformation of the housing, for instance due to pressure being exerted by the index finger and/or thumb in the region of the finger rest, the reservoir is likewise deformed. Light-curable material can exit as a result of this deformation of the reservoir.
- In certain embodiments, the housing is deformable only in the region of the reservoir, in particular without being damaged and/or under use conditions. In other embodiments according to the invention, it is deformable to a greater extent or completely.
- In some embodiments according to the invention, the device has the reservoir and the light-emitting unit, for example the at least one LED lamp, at two opposite ends (relative to a longitudinal axis of the device). These regions may also be referred to as end regions.
- In one form of the housing as a writing instrument, the device may be used on the one hand for discharging and metering the light-curable material, and on the other hand, when the device is rotated through for example 180 degrees about a central or transverse axis, for curing the light-curable material by means of the light-emitting unit, for example the LED lamp.
- The light-emitting unit, for example the LED lamp, can in some embodiments be removed from the device. The light-emitting unit can then be used as a stand-alone unit as a curing lamp. The light-emitting unit may be attached by means of an elastic clip-fastening or snap-fastening to the housing, which is configured for example as a plastic housing, preferably in such a way that it can be removed again therefrom without any damage being caused.
- In some embodiments according to the invention, the device has a section for fitting an attachment onto the device, wherein a discharging and/or metering of the light-curable material is aided by the attachment. The attachment may be designed as a nozzle for example. In certain embodiments, the reservoir can be filled (for the first time or refilled) with light-curable material via the attachment.
- In some embodiments according to the invention, the device has an adaptable connection or an attachment for discharging and metering the light-curable material and/or for filling the reservoir.
- The adaptable connection or the attachment may be able to be detached again, or it may alternatively not be able to be detached again. In certain embodiments, a connection or attachment that cannot be detached again is formed by a snap-fastening, for example an elastic hook, which snaps in after being placed onto the device. In some embodiments, the connection or attachment that can be detached again is pushed on, screwed on, fixed by means of a bayonet fastening or connected by a different type of fastening.
- A connection or attachment that can be detached again may be detached again after a single use or after multiple uses. By way of example, a different adapter having in each case a different opening cross-section or opening profile for different metering quantities can be used depending on the application.
- The same adapter or attachment as used for discharging and metering may be used for filling the reservoir. However, a different adapter that is specifically suitable for filling purposes may also be used. This may have, for example, a specific shape for the placement and/or fixing of an external filling container. Furthermore, the opening cross-section of the adapter may be much greater than that used for discharging and metering, in order to carry out the filling process rapidly so as, for example, largely to avoid premature curing by light components during the filling process.
- In some embodiments according to the invention, the device has a closure cap which is placed onto the housing, in a manner such as to be able to be detached again, onto the end-face opening of the reservoir or the discharge path thereof. The closure cap may be fixed onto or to the housing, in particular temporarily, by a friction pairing or another method or device known to the person skilled in the art.
- This closure cap is preferably impermeable to light, at least for light having wavelength ranges at which the light-curable material cures. The closure cap may be placed on with or without an adaptable connection for discharging and metering purposes.
- The present invention proposes a method for discharging and/or for curing the light-curable material using a device according to the invention having at least one reservoir for a quantity of light-curable material and/or a light-emitting unit, in particular an LED lamp.
- The discharging of the light-curable material may take place by applying manual pressure to the housing, to a pressing or displacement unit and/or to the reservoir. By virtue of a manual application of pressure, metering can advantageously take place with the precision required for the respective application.
- In one inventive embodiment of the method, a manually controlled metering mechanism is actuated in order to discharge the light-curable material from the reservoir in a metered manner.
- In some inventive embodiments of the method, it is proposed which, after the curing of the material, comprises a rotation, turning-over or tilting of the device about a transverse axis of the device, with subsequent activation of the curing by the light-emitting unit, for example the LED lamp.
- The set comprises at least one device according to the invention and a quantity of light-curable material.
- In certain embodiments, the set further comprises a closure cap for the device and/or one or more attachments for metering the light-curable material for the device.
- In some embodiments, the set according to the invention is packaged by means of visible packaging (which is also referred to as blister packaging), which comprises the device according to the invention having a reservoir and/or an LED lamp, a quantity of light-curable material and a closure cap for the device.
- When mention is made herein of a light source, flashlight device or other device according to the invention which is suitable and/or intended and/or designed for curing the light-curable material, the device in question may be liquid-proof or waterproof. Here, the term liquid-proof or waterproof is to be understood to mean that the curing device can be used for repeated use in liquid or in water. This suitability may be brought about by means of suitable seals, coatings, insulations and/or the like.
- By means of the flashlight device according to the invention, it is advantageously possible to glue or to permanently or temporarily bond objects to one another using cost-effective means. With the modeling, it is possible to produce hooks or pegs, for example, in addition to depicting objects. Due to and depending on the light-curable materials used, it is possible to produce, for example, hooks or the like which adhere to glass, flows, wood, plastic, stone, etc.
- The use of the method according to the invention differs from known methods and from the “conventional” adhesive systems of the prior art inter alia in that, according to the invention, there is no need to wait for the “adhesive” material used, that is to say the light-curable material, to cure. The bonding effect of the light-curable material is obtained virtually immediately.
- In some embodiments, therefore, bonding can take place in a time-saving manner by means of the method according to the invention. In addition, there is no need for tiresome holding of parts of elements that are to be bonded. These parts and elements can be placed in position and, once the position has been checked, are fixed to one another by targeted illumination. The fixing takes place at the moment of curing. This may take place within a fraction of a second. A primary fixing of elements can thus be achieved in the blink of an eye. A primary fixing is achieved after just 300-500 ms. The curing process is complete after approximately 5-8 s. Any subsequent reinforcements of the bonding sites can be taken care of without any time pressure.
- Depending on the choice of the light-curable material used, this can be removed again at any time without leaving a residue. Bonds can be dissolved quickly and without any problem, and surfaces remain absolutely unharmed. In some embodiments, therefore, the method according to the invention can be carried out without hesitation in rented homes and holiday homes, exhibitions and trade fairs and the like. The cured adhesive can be removed without leaving any residue.
- In the private, industrial or commercial and non-dental sector, the method according to the invention can be used in crafts and model-making as well as in architecture, planning and engineering offices, in electronics and medical technology and even applications in the hobby and household sector.
- Depending on the power of the flashlight device or polymerization lamp that is used, a higher performance and an associated shorter curing time can be achieved.
- A high viscosity of the light-curable material means a sufficient stability. This property, paired with the single moment of curing, offers the possibility of creating or building objects in layers. The light-curable material used can optionally be post-processed by milling and polishing.
- By means of the method according to the invention, small-area bonds and spot-type bonds as well as bonds between uneven surfaces can be achieved particularly well, especially when also using the flashlight device according to the invention.
- Furthermore, any objects such as jewelry, decorative articles, art, etc. can advantageously be duplicated. To this end, it may be sufficient to make an impression or a mold of an object and, once the object has been removed from the mold, to fill said mold with the light-curable material. The latter can be cured within the mold by the flashlight device according to the invention or by the LED standard lamp. Once the solid material has been removed from the mold, it can if necessary be briefly illuminated again from all sides. If desired, the finished “clone” can be subsequently worked on using tools.
- Therefore, by means of the present invention, using only a light-curable composite material and a novel light system, for the first time an inexpensive and above all easy-to-handle solution can be used by anyone instead of the cost-intensive UV adhesive technology used in industry.
- The bonds achieved may be reversible. The light-curable material used can be removed without leaving any residue and does not attack the surfaces of the objects.
- By means of the method according to the invention, it is advantageously possible to fill joins. In some embodiments, this can also advantageously be used to seal against the ingress or escape of moisture or liquid. In this case, too, it is advantageously possible to work without any time pressure: the material used is not hard until the user wishes it to be and causes it to be as a result of applying light. In this case too, therefore, positioning can first take place calmly and then curing can take place within a matter of seconds.
- By means of the method according to the invention, objects can moreover advantageously be created in layers. In some embodiments, the method according to the invention is therefore also highly suitable for the three-dimensional printing of objects or for constructing objects in some other way from the light-curable material used or for the additional processing thereof.
- By means of the device, in some of the embodiments according to the invention, on the one hand the light-curable material can easily be applied by holding and operating the device with one hand. Advantageously, by rotating, tilting or turning the device through, for example, 180 degrees (i.e. about a transverse axis of the device), the applied material can then be cured by means of the LED lamp on the opposite end face of the device. The sequence of activities, applying and then, after rotating the device, curing, advantageously prevents the light-curable material from running out of the device even when no closure cap has been placed on a discharge opening of the reservoir. Said closure cap is not necessary during this handling, which can make it very easy and pleasant to work with the device according to the invention. Overall, the device is easy and safe to handle.
- One possible use example of the present invention is the gluing-on of artificial fingernails, as is known in a nail studio. The present invention can in this case advantageously contribute to a considerable time saving.
- Another use example of the present invention is the gluing, repairing, attachment, etc. of objects such as tiles, fixings or the like, which are present in a liquid. For instance, in some embodiments for example, a crack in a tile can be fixed by means of the method according to the invention using the light-curable material under water and thus in the wet. According to the invention, there is no need to leave the water in order then to close the crack in a dry environment. This advantageously makes it possible to make a saving in terms of effort and costs in connection with work carried out on objects located underwater for example, such as the hull of a ship.
- The present invention will be explained by way of example below with reference to the appended drawing, in which identical reference signs denote identical or similar components. In the figures, which are in part shown in highly simplified form:
-
FIG. 1 schematically shows, in simplified form, a device according to the invention in the form of acorner protector 100, in a perspective view. It is not only suitable but rather is expressly intended for being bonded to a structure (not shown inFIG. 1 ). - Such a bonding may take place by means of a flashlight device 105 or other suitable light devices. The
corner protector 100 has two retention means 110, wherein the number two is to be understood here to be purely by way of example. - The retention means 110 are intended to accommodate a quantity of light-
curable material 120. The latter can be cured by means of the flashlight 105 in order to bond thecorner protector 100 to the structure 200. The light-curable material 120 is shown darker in contrast inFIG. 1 relative to the rest of thecorner protector 100, which is transparent here by way of example. - As can be seen in
FIG. 1 and alsoFIG. 2 , the retention means 110 are designed as an undercut within thecorner protector 100. By means of the retention means and the associated possibility of accommodating light-curable material therein, it is advantageously possible for thecorner protector 100, after curing, to be held on the household furniture 200 even when thecorner protector 100 has no surface properties for permanent or stable or reliable bonding by means of the light-curable material 120. By providing the retention means 110, it may be possible to produce a reliable hold between thecorner protector 100 and the structure 200 even when the light-curable material 120 is not suitable for generating an or a sufficiently stable adhesive bond between thecorner protector 100 and the light-curable material 120. The bond is generated to a lesser extent or not at all by the adhesive effect between thecorner protector 100 and the light-curable material 120; instead, it is generated by a force fit and/or form fit in that the light-curable material 120 cures in the retention means 110 and is bonded to thecorner protector 100 by the curing. - The device, which is configured by way of example as a
corner protector 100, may in this case be made of or comprise a first material; the structure 200 may be made of or comprise a second material, wherein the first and the second material are different from one another or are identical. - The structure 200 may be an item of household furniture or any other structure.
-
FIG. 3 shows a further device according to the invention in the form of ahook 300. The latter is shown as a side view in the left-hand diagram ofFIG. 3 and as a front view in the right-hand diagram. Thehook 300 has a hook section 310 with aretention space 320. Thehook 300 further has abase retention plate 330. Theretention plate 330 containsperforations 340. The latter can accommodate excess light-curable material prior to the curing of the latter. In this way, the excess material is “cleared away”; it may also make its own contribution to the adhesive strength that can be achieved between thehook 300 and the wall surface (not shown). -
FIG. 4 shows a flashlight device according to the invention for curing the light-curable material, in the form of a lamp/magnifying glass combination 400. The latter stands on abase 410 and is designed to be flexible in aregion 420. The lamp/magnifying glass combination 400 carries onemagnifying glass 430 or a plurality of magnifying glasses, optionally of different strength. Afirst lamp 440 emits the light necessary for curing purposes. A second,optional lamp 450 emits any desired light and can be used, for example, for working or illumination purposes. In certain embodiments, thesecond lamp 450 emits any desired light but not light used for curing purposes. In some embodiments, thesecond lamp 450 emits no or substantially no light in the wavelength range of thefirst lamp 440. - A foot-operated switch, a hand-operated switch, an acoustic switch or the like may be provided for actuating the
first lamp 440. - The base 410 may be able to be attached by means of a clamp, a magnet, a pedestal or the like. It may have an anti-slip coating or may comprise an anti-slip material.
-
FIG. 5 shows a further device according to the invention in the form of apen 500 having areservoir 510 for the light-curable material 120 and having anLED lamp 520 as an example of a light-emitting unit. - For use purposes, the
pen 500 is intended to be held by one hand. Afinger rest 530, which is not absolutely necessary, is provided for an advantageously precise and secure guidance and handling of thepen 500 by the hand. - The
housing 540 of thepen 500 is advantageously impermeable to light and is made of plastic for production reasons. Thehousing 540 is softer or more flexible in the region of thefinger rest 530 than in the rest of thehousing 540. As a result, using the fingers, pressure can be exerted on thehousing 540 via thefinger rest 530 and thus pressure can be exerted on theinternal reservoir 510. As a result of this pressure, thereservoir 510 is compressed in the middle and rear, closed part of thereservoir 510. As a result, the light-curable material 120 is discharged from thereservoir 510 through the exit opening orreservoir opening 515 out of thepen 500. - The
exit opening 515 is adjoined by an (optional, not absolutely necessary)adapter 550 which is intended to adapt or to hold a push-on or screw-on, preferably light-impermeable, nozzle 560 (as an example of an attachment). The movement direction of the nozzle, both when being pushed on and when removing thenozzle 560, is illustrated by thearrow 565. By virtue of thisnozzle 560, the light-curable material 120 to be applied can be finely metered according to the nozzle opening cross-section. Thenozzle 560 can also be used to fill thereservoir 510 with light-curable material 120. - Furthermore, a
closure cap 570 can be pushed onto thehousing 540 in one of the end regions of the device. Theclosure cap 570 is, inter alia, impermeable to light so that, for example, remaining light-curable material 120 in the closure cap does not cure, for instance by means of ambient light. Theclosure cap 570 can moreover offer advantageous protection against general dirt and can serve as protection during transport, etc. Theclosure cap 570 is pushed on and/or removed in theillustrated direction 575. - The
LED lamp 520 is located at the other end region or end of thehousing 540, relative to thelongitudinal axis 580 of the device. ThisLED lamp 520 is, for example, inserted in thehousing 540. It is preferably fixed by means of an undercut in thehousing 540, which may be made of or comprises an elastic plastic. In certain embodiments, therefore, theLED lamp 520 can be removed from the device. In the embodiment shown inFIG. 5 , theLED lamp 520 can be switched on and off by finger pressure by means of aswitch 525. After being switched on, theLED lamp 520 may be lit permanently until it is switched off or may turn itself off again for example by means of a time control. - The
LED lamp 520 can also be switched on in thehousing 540 and can emit light outward, for example by means of a flap (not shown here). TheLED lamp 520 can thus optionally be operated internally, that is to say while remaining in thehousing 540, or externally, after being removed from thehousing 540, in order to cure the applied light-curable material 120. -
FIG. 6 shows the device ofFIG. 5 in one possible use. - The
pen 500 is held in the hand, the index finger and thumb of the hand are located on thefinger rest 530. The index finger and thumb can exert pressure on thehousing 540, which is more flexible at this location, and on thereservoir 510 located therebelow. As a result of this pressure being exerted, the light-curable material 120 is transported or applied outward from thereservoir 510 through thenozzle 560. - By rotating the
pen 500 about the transverse axis 585 (see alsoFIG. 5 ), the pen can be held the opposite way round in thehand 600. A curing of the applied light-curable material 120 is then possible for example when theinternal LED lamp 520 is switched on and LED light can exit for example through an opening at the rear end of thepen 500. At the same time, however, advantageously no additional light-curable material can drop out of thereservoir 510 counter to the force of gravity. - The present invention is not limited to embodiments described herein; reference should be had to the appended claims.
