Description

The invention relates to a light module having an annular printed circuit board on which a plurality of semiconductor light sources and electronic components are arranged. The invention also relates to a lamp with such a light module. The invention is particularly applicable to LED light modules.

Siteco sells a light module of the relevant type under the trade name "Lunis R ^® LED". However, this light module is complex to manufacture.

Another light module, which has a ring-shaped printed circuit board on which several semiconductor light sources and electronic components are arranged, is sold by Osram under the trade name "PrevaLED". Here the semiconductor light sources are arranged in a central area and surrounded by the electronic components in a ring shape.

Known from US 2010/0208474 is a light module with a circuit board, LEDs being arranged on an outer portion of the circuit board and electronic components being arranged on an inner portion of the circuit board. LEDs and electronic components are covered with a cover.

DE 10 2011 077 323 A1 discloses a light module with a circular disk-shaped circuit board on which a plurality of semiconductor light sources and electronic components are arranged. The semiconductor light sources are arranged in a central area of the circuit board, the electronic components are provided in an area arranged in a ring around the central area.

JP 2013 026168 and JP 2012 253026 disclose lights, wherein the semiconductor light sources are attached to an annular circuit board.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and, in particular, to provide a particularly easy to manufacture and long-life light module of the type in question with a large light-emitting surface.

This object is achieved according to the features of the independent claims. Preferred embodiments can be inferred in particular from the dependent claims.

The object is achieved by a light module having an annular printed circuit board on which a plurality of semiconductor light sources and electronic components are arranged, the semiconductor light sources on an outer partial area of the printed circuit board and the electronic ones Components are arranged on an inner portion of the circuit board.

By arranging the semiconductor light sources on the outer sub-area, a large-area emission area can be provided. In addition, an arrangement density of the semiconductor light sources can be reduced in this way, which leads to a lower thermal load on the semiconductor light sources. This in turn enables improved longevity. The arrangement can also be produced particularly easily due to the spatial separation of the semiconductor light sources and electronic components in the inner and outer subareas.

The light module can, in particular because it has electronic components, also be referred to as a “light engine”. "Outside" or "inside" (and forms formed therefrom such as "outer area", "outside" etc.) as location details in the context of this application relate in particular to a centroid of the light module and / or the circuit board, these preferably being in a Spatial direction has a significantly smaller extent than in two perpendicular spatial directions (so-called flat configuration), ie outer or outer points or areas are further away from the centroid than inner or inner points or areas.

The fact that the circuit board is ring-shaped may include, in particular, that the circuit board has a central recess which is at least for the most part (e.g. at least 80% of the circumference, in particular with at least 90% of the circumference, in particular 95% of the circumference) from the circuit board is surrounded. The recess may serve in particular to lead through at least one electrical supply line or a power supply, for example a mains supply line, for example in the case of wall mounting. This development has the advantage that the semiconductor light sources, the electronic components and the electrical supply lines are essentially can lie in one plane, which enables the provision of very flat luminaires. The center of gravity of the central recess does not necessarily have to coincide with the center of gravity of the conductor bar, ie it is sufficient if it is virtually enclosed by a ring of electronic components and semiconductor light sources. The size of the recess is measured according to its function and the requirements of the light module as well as the conditions in the production of the same, in particular from the point of view of simple and / or material-saving production.

The circuit board may be a circuit board that is closed all the way around the recess. This enables simple production and a mechanically stable design. However, it may also have a continuous slot or the like, which makes it easier to deform.

The circuit board is in particular at least substantially ring-shaped or has a ring-like basic shape in such a way that locally limited projections or recesses can occur on its edges.

The ring shape may be circular, but is not limited to it. When viewed from above, it may have an oval, angular (e.g. rectangular, hexagonal or other polygonal shape), free-form, etc., inner and / or outer edge. The basic shape of the inner and outer edges may be the same or different.

The fact that the electronic components are arranged on the inner sub-area of the circuit board may in particular include that all electronic components are arranged on the inner sub-area of the circuit board. Alternatively, all electronic components except for at least one ohmic resistor and / or at least one diode may be arranged on the inner sub-area of the circuit board.

In particular, the electronic components can be distributed with approximately the same density over the inner sub-area, i.e. in particular the number of components on a given area is approximately the same for the majority of the sub-areas, in particular for all sub-areas of the inner sub-area. A partial area can correspond in particular to an area which corresponds to a quarter, preferably an eighth, particularly preferably a tenth of the area of the inner partial area. The partial area can, however, also correspond to an area which corresponds to 20 times, preferably 10 times the area of an electronic component, in particular the largest electronic component or the smallest electronic component or an average-sized electronic component. As a result, on the one hand, the thermal load from the electronic components is distributed over a larger area. On the other hand, this can also shorten the paths from the electronic components to the individual semiconductor light sources compared to a concentrated arrangement of the electronic components.

The semiconductor light sources may be or have light-emitting diodes. If there are several light-emitting diodes, they can light up in the same color or in different colors. A color can be monochrome (e.g. red, green, blue etc.) or multichrome (e.g. white). The light emitted by the at least one light-emitting diode can also be an infrared light (IR-LED) or an ultraviolet light (UV-LED). Several light emitting diodes can produce a mixed light; eg a white mixed light. The at least one light-emitting diode can contain at least one wavelength-converting phosphor (conversion LED). As an alternative or in addition, the phosphor can be arranged remotely from the light-emitting diode (“remote phosphor”). The at least one light-emitting diode can be in the form of at least one individually housed light-emitting diode or in the form of at least one LED chip. Several LED chips can be mounted on a common substrate (“submount”). The at least one light emitting diode can with at least be equipped with its own and / or common optics for beam guidance, for example at least one Fresnel lens, collimator, and so on. Instead of or in addition to inorganic light-emitting diodes, for example based on InGaN or AlInGaP, it is also generally possible to use organic LEDs (OLEDs, for example polymer OLEDs). Alternatively, the at least one semiconductor light source can have, for example, at least one diode laser.

The electronic components may serve to convert an electrical supply signal into an electrical signal suitable for operating the semiconductor light sources ("driver components"). However, the electronic components can also perform other functions. The electronic components may include capacitors, resistors, coils, switches, potentiometers, electronic switches (such as transistors, etc.) and / or integrated semiconductor components or ICs such as microcontrollers, ASICs, FPGAs, etc.

The inner sub-area and / or the outer sub-area is in particular an annular sub-area. It may have the same basic shape as the circuit board, e.g. a circular ring-like shape.

The circuit board may be a metal core board, which enables particularly effective heat spreading. However, it may also have a base material made of FR4 or ceramic, etc.

It is a further development that the printed circuit board is equipped with the semiconductor light sources only on one of its flat sides (hereinafter referred to as “front side” without restricting generality).

It is still a further development that the printed circuit board is equipped with the semiconductor light sources and the electronic components only on its front side. The other flat side (hereinafter without loss of generality referred to as "back") is not equipped. The rear side can then be used particularly simply as a support surface, for example for fastening to a heat sink. The rear side may also be exposed and, due to its large area, can itself serve as a cooling surface for the semiconductor light sources and the electronic components.

According to the invention it is provided that the semiconductor light sources and the electronic components are arched over by a cover which is at least partially translucent. The cover enables, among other things, protection against mechanical and / or chemical stress or the penetration of insects. Furthermore, it serves as an electrical contact protection, so that, in the attached state, predetermined safety distances to components connected to a supply voltage (in particular mains voltage) are maintained. In this way, grounded and / or ungrounded metal parts can also be attached to both sides of the circuit board. For this purpose, the cover is preferably made of an electrically insulating material. In this context, at least partially translucent can in particular mean that part of the cover is not translucent while another part is translucent.

The cover can also serve as a privacy screen, e.g. to prevent the electronic components from being viewed. In addition, the cover can be used for the simple attachment of further components, for example attachments. The transparent areas serve in particular for coupling out light generated by the semiconductor sources.

It is a further development that the cover is a cover produced in one piece. The cover may consist of plastic, for example. When using areas of different composition, for example translucent and non-translucent and / or transparent and opaque areas, the cover can be produced, for example, by multi-component injection molding. However, the cover may also consist entirely of translucent material.

It is a further development that the cover is a multi-part cover. This may include that the cover is produced by attaching at least two separate parts to the circuit board, or that the cover has been assembled from at least two previously separately produced parts, for example fabric, force and / or prior to being attached to the circuit board form-fitting. At least a part of this may be translucent and at least one other part may be opaque. At least one part may also be transparent and at least one other part may be opaque. The translucent part may, for example, arch over the semiconductor light sources, the opaque part, for example, the electronic components. The cover may be designed in particular flat, that is, the height of the cover is in particular less than a fifth, preferably less than a tenth, particularly preferably less than a twentieth of a main extension of the ring-shaped circuit board, in particular the largest edge length of a rectangular ring-shaped circuit board or a diameter of a circular circuit board. The height is in particular the distance between the highest point of the cover and the front of the ring-shaped printed circuit board.

The translucent areas of the cover may in principle be designed to be transparent or opaque or translucent. In principle, both transparent and opaque areas can also be present.

According to the invention it is provided that at least one channel is arranged on an inner side wall of the cover. In particular, at least one electrical Supply line, which runs through the central recess, can simply be guided under the cover to the circuit board. The at least one channel enables safety clearances to be maintained and a connection that is particularly easy to assemble.

It is an embodiment that the semiconductor light sources have a predetermined radial distance from the electronic components. This spatial separation prevents light from being shaded by the electronic components. In this way, shading of the light emitted by LEDs can be prevented, which the LEDs typically emit at a radiation angle of approx. 120 °. It also allows a cover to be placed between them in a particularly simple manner.

Another embodiment is that the semiconductor light sources are arranged on the printed circuit board in a ring shape, individually or in groups, in the circumferential direction, in particular at equidistant spacing. This enables particularly uniform light emission in the circumferential direction. The individual arrangement may include that the semiconductor light sources individually already generate the useful light emitted by the light module, for example white light. The group-wise arrangement may include a plurality of semiconductor light sources being arranged close to one another as a group and at least two of these semiconductor light sources emitting light of different colors. Only the mixing of the light from the semiconductor light sources in the group results in the useful light. For example, white light of a first LED of the group may be mixed with red light of a second LED of the group in order to produce a warm-white useful light in the mixture. For example, at least one red LED, at least one green LED and at least one blue LED may also belong to a group. Yet another example is the use of at least one green and white glowing LED and at least one amber, red, or orange luminous LED, for example in the form of the so-called "Brilliant Mix" from Osram.

It is also an embodiment that a plurality of latching elements are arranged on the printed circuit board, in particular on its front side. This enables additional components, e.g. a cover, to be attached simply and securely in a form-fitting manner. The latching elements can be inserted into a respective hole in the circuit board, for example, and fixed therein in a form-fitting, material and / or force-fitting manner, e.g. by soldering, gluing, clamping, etc. The latching elements can be made of plastic or metal, e.g., aluminum.

The locking elements may have an inner channel which lies along their longitudinal extension. The channel enables a fastening element, for example a screw, to be passed through the circuit board, for example for fastening additional modules to a rear side of the circuit board. The inner channel may be smooth or, for example, equipped with a thread. The latching element may in particular be tubular or sleeve-shaped. There may be at least one latching area on its outer surface, e.g. an undercut or a latching projection.

It is still another embodiment that the cover is locked with the latching elements. In this way, the cover can be securely attached to the circuit board by means of a simple pressing process. Alternatively, the cover may have latching elements, for example latching hooks, which can be brought into engagement with an edge of the circuit board in order to fasten the cover. However, the cover may also be connected to the circuit board in other ways, e.g. by hot caulking, ultrasonic welding, laser welding, screwing on, unscrewing, etc.

It is also an embodiment that at least one group of holes aligned with one another (possibly also longitudinal holes) is present in the cover and in the printed circuit board. This enables fastening elements, e.g. screws, to be introduced through the circuit board and the cover, e.g. for fastening directly to a wall or ceiling. This enables a particularly flat design and eliminates the cost of parts for additional assembly components. A mounting adapter can be attached to the circuit board through the holes, e.g. for hanging mounting on the back of the circuit board.

In particular, the latching element equipped with the channel may be inserted into the hole in the circuit board.

It is also an embodiment that at least one fastening area for, in particular, form-fitting fastening of at least one external unit or component (hereinafter referred to as “top unit” or “additional module” without loss of generality) is present on the cover. The cover enables a particularly wide range of options for attaching the at least one add-on unit.

In one embodiment, in particular, the cover has an upstanding, in particular ring-shaped area which arches over the electronic components. This provides a large volume for accommodating the electronic components, in particular if these do not have a low overall height, for example capacitors. In order to avoid shading the light emitted by the LEDs, the raised area may be bevelled towards the outside. The highest ring-shaped area can separate the electronic components from the semiconductor light sources, ie in particular an at least approximately closed space is made available in which the electronic components are arranged, but none Contains semiconductor light sources. This allows the electronic components to be shielded from the light from the semiconductor light sources. For this purpose, the upstanding, in particular ring-shaped area which arches over the electronic components is preferably designed to be opaque.

Another embodiment is that at least one fastening area is present on the outer side wall of the cover, in particular its upstanding area. Among other things, this enables an attachment unit with a wide base to be attached. The arrangement on the outer side wall enables, for example, a fastening by means of a clamp connection, a rotary connection or a latching connection, e.g. by means of a plug-in and / or rotary movement or a linear plug-in connection. An attachment unit that can be fastened there may be, for example, a transparent cover and / or an optical element (“additional optics”), for example a reflector.

If the at least one fastening area extends up to an upper side of the upstanding area, a simple form-fitting fastening of the attachment unit is made possible, for example by means of a plug-in / turn process, for example in the form of a bayonet lock. For this purpose, a longitudinal slot may start at the top of the upstanding area, at the end of which a transverse slot starts at least at right angles on the outer side wall. Alternatively, the fastening area may be designed for simple linear latching, e.g. in the form of a snap device.

It is also an embodiment that at least one fastening area is present on the inner side wall of the cover, in particular its upstanding area. This also enables an attachment unit to be attached. If the at least one fastening area extends up to an upper side of the upstanding area, a simple one is also here allows positive attachment of the attachment by means of a plug / turn process, for example in the form of a bayonet lock. For this purpose, a longitudinal slot may start at the top of the upstanding area, at the end of which a transverse slot starts at least at right angles on the outer side wall. However, a form-fitting attachment of the attachment unit may also be provided here by means of a simple linear latching movement, for example in the form of a snap device.

In particular, by means of the at least one fastening area present on the inner side wall, attachment units in the form of a cover plate or an electrically operated additional module can be attached. The electrically operated additional module may, for example, have at least one sensor, e.g. comprising a brightness sensor, a motion detector, a smoke detector, etc. This additional module may be supplied via the circuit board, the electrical connection for the circuit board or via a separate electrical connection.

It is a further development that at least one additional circuit or function (or corresponding electronic components) is present on the inner part of the circuit board, e.g. a radio receiver and / or radio transmitter, a motion detector, a light sensor, etc.

It is still another embodiment that the cover has at least one beam-shaping transmitted light area. This enables effective beam shaping without additional optics. A beam-shaping area may be a lens-like area, for example. A beam-shaping region may be assigned to several semiconductor light sources or groups of semiconductor light sources, in particular all semiconductor light sources or groups of semiconductor light sources. A beam-shaping region may also be an individual semiconductor light source or in each case be assigned to a single group of semiconductor light sources.

Another embodiment is that a fastening adapter is arranged on the side of the printed circuit board facing away from the semiconductor light sources and electronic components. This may be designed, for example, to attach the light module to a wall or a ceiling. It may also be designed as a hanging lamp for the use of the light module.

It is also a further development that pushbuttons are integrated in the cover, in particular above the inner partial area. In this way, elements attached to the circuit board can be operated, for example electrical switching elements (e.g. an on / off switch, a dimmer) and / or cable clamps. The push button may, for example, be designed as a partially cut-out tab.

The cover may furthermore have at least one hole or recess, for example for the implementation of control elements or for access to control elements such as potentiometers.

At least one strain relief for at least one electrical supply line, e.g. an electrical cable, may be located on the circuit board and / or on the cover.

The object is also achieved by a lamp which has at least one light module as described above.

In a particularly simple embodiment, the lamp consists only of the light module with the printed circuit board and the cover.

It is an additional or alternative development that the luminaire has the light module and additionally a diffuser which covers at least the outer partial area provided or equipped with the semiconductor light sources. This enables a particularly homogeneous light emission reach. The diffuser may be attached to the cover, in particular by means of a plug-in movement, a rotary movement or a plug-in / rotary movement.

It is a further development that the diffuser has a reflective area and / or is connected to a reflector in order to deflect light for a particularly advantageous light emission. The reflector may be locked to the diffuser, e.g. snapped into place, e.g. via locking or snap hooks. The diffuser and the reflector may be annular. With the attachment of the diffuser, the reflector can be placed, for example, above the semiconductor light sources of the light module. By means of the reflector, the light generated by the semiconductor light sources can then be radiated over a large area to the outside, so that a diffuser protruding laterally over the printed circuit board can be illuminated almost homogeneously.

So that the semiconductor light sources do not protrude too strongly, the diffuser is preferably designed with a relatively large distance from them.

In order to prevent the reflector from casting a visible shadow edge, this shadow edge is preferably placed in an edge or step of the diffuser.

Another development is that the lamp has the light module and, in addition, a cover (referred to below as a cover or cover plate without restricting generality) that covers or vaults the inner partial area and / or the central recess. The cover plate may, for example, have a circular shape. The cover plate may, for example, be opaque, so that a view of the components of the inner partial area and of the central cutout and, if applicable, electrical supply lines guided through it can be prevented. For this purpose, the cover plate may consist of an opaque material, for example of colored plastic. But the cover also likes be transparent or opaque, with an in particular round insert plate or insert disk being able to be inserted under the cover. This insert plate can be defined by an end user and, if necessary, also exchanged, so that the center of the lamp can be personalized, for example in terms of color or materiality (fabric, wallpaper, etc.). A small part of the light generated by the semiconductor light sources may also be directed into the center of the luminaire so that it does not remain dark.

The cover disk can be connected to the diffuser or to the cover via, for example, a plug-in mechanism (including a snap), a rotating mechanism or a plug-in / rotating mechanism. The cover plate may be designed for the attachment of further elements, e.g. information elements, e.g. made of light-conducting material.

The surface of the cover plate may be partially satined, in particular on an outer area that covers the diffuser, in particular if the cover plate is made of a transparent material. For example, a fastening mechanism behind the satined surface (e.g. a latching or snap mechanism) can be covered and light can still be guided through the diffuser into the center of the cover panel.

The surface of the cover plate may additionally or alternatively be partially painted or partially vapor-coated, so that part of the light is passed on radially inward.

The diffuser can protrude upwards or forwards in such a way that the diffuser surface protrudes in height beyond at least one outer ring area of the cover plate. In order to prevent unclean reflections on the, in particular, transparent cover panel, it can be of a slightly curved shape.

Diffuser and cover plate can also be present as a single part, which is partially satined in its outer area and transparent in the middle or completely opaque.

It is also a further development that the fastening adapter is attached to the rear of the printed circuit board, in particular as a wall structure. On the one hand, this enables the feeding of a supply line that is laid on the wall and, for example, also offers the strain relief required for such lines. In the case of the wall structure, the wall structure is first attached for easy assembly. Then, for example, the supply line is laid and screwed to the strain relief. The light module can then be connected to the wall structure at the fastening points instead of being screwed directly to the wall.

Another development is that an annular plate ("back plate") protruding laterally over the printed circuit board is attached to the rear side of the printed circuit board. This may lead to more effective heat dissipation and cooling, especially if it is made of metal, e.g. a metal sheet. Additionally or alternatively, the back plate may serve as a support or connection of an additional module or attachment unit fastened on the front, in particular on the cover of the light module. In this case in particular, the back plate may also consist of plastic. This additional module may also protrude laterally over the circuit board. This additional module and the back plate may be connected to one another at their congruent outer edges.

The rear panel can have a curvature on its outer edge, which advantageously prevents light from escaping from the side and guides the diffuser circumferentially during assembly. The curvature may, for example, be designed as a forward-facing embossing in the rear panel. Light reflected at the curvature is directed especially towards the front of the diffuser and likes you there lightly generate a brighter glowing ring of light. By varying the shape, in particular the course, the curvature, the shape of the light ring can be changed, e.g. into a spiral, a ray pattern, etc.

An ungrounded back plate made of electrically conductive material is advantageously cut out accordingly around the central cutout of the printed circuit board or has a predetermined distance from the cutout in order to maintain safety distances. In principle, the back plate may have a central cutout which is smaller, equal to or larger than the cutout in the circuit board. The recesses in the circuit board and the back plate can be arranged concentrically or in alignment with one another.

The luminaire described above enables a large-area, flat luminaire structure based on the light module. A customizable field may also be illuminated through the light guide in the middle of the luminaire. The small number of parts results in a cost-effective overall concept.

While an invisible rear side R of the printed circuit board 2 is not equipped, the front side V shown is equipped with several semiconductor light sources in the form of LEDs 8 and with several non-light-emitting electronic components 9, 10. The LEDs 8 are, for example, LED chips emitting white light. They are arranged in an equidistant ring-shaped manner in a circumferential direction of the printed circuit board 2. The electronic components 9, 10 (e.g. capacitors, resistors, coils, switches, potentiometers, integrated semiconductor components or ICs such as microcontrollers, ASICs, FPGAs, etc.) form at least part of a driver or control for the LEDs 8 provide other functions, e.g. that of a radio transmitter and / or radio receiver, a motion detector, etc.

The LEDs 8 are arranged on an annular outer partial area 11 of the printed circuit board 2 and the electronic components 9, 10 are arranged on an annular inner partial area 12 of the printed circuit board 2. The LEDs 8 are radially spaced inwardly from the electronic components 9, 10 and outwardly from the outer edge 4. The electronic components 9, 10 are spaced apart from the inner edge 5. By arranging the LEDs 8 on the outer partial area 11, a large-area emission area can be provided. In addition, thus reduce an arrangement density of the LEDs 8, which leads to a lower thermal load.

This circuit board 2 has the advantage that the LEDs 8, the electronic components 9, 10 and the electrical supply lines are essentially in one plane, which enables a very flat design.

A plurality of fastening elements in the form of locking sleeves 13 are also arranged on the front side V of the circuit board 2. The locking sleeves 13 are arranged uniformly distributed in the circumferential direction in the inner sub-area 12.

Fig. 2 shows a differently equipped ring-shaped circuit board 2, 2b of the light module 1 in a view from above at an angle. In contrast to the circuit board 2a from FIG Fig. 1 respective groups of two LEDs 8a, 8b are now arranged in a ring on the outer partial area 12 of the circuit board 2. The LEDs 8a, 8b of a group are arranged close to one another in order to support effective light mixing. The groups of LEDs 8a, 8b are arranged on the circuit board 2 in the shape of a circular ring with a group-wise equidistant distance in the circumferential direction.

The LEDs 8a and 8b may, for example, emit white light or red light or green-white or amber-colored (“amber”) light.

In addition, the locking sleeves 13 are not shown, but the holes 14 in the circuit board 2 into which the locking sleeves 13 are inserted.

Fig. 3 shows in a view obliquely from above the light module 1 with, purely by way of example, the printed circuit board 2b Fig. 2 with an annular cover 15 attached to the circuit board 2. The one-piece cover 15 covers the entire front side V of the circuit board 2, and thus also the LEDs 8a, 8b and the electronic components 9, 10. Die Cover 15 here consists of transparent plastic and may be in the form of an injection-molded part.

Fig. 4 shows the cover 15 in a view obliquely from above. Fig. 5 shows the cover 15 in a plan view obliquely from above. Fig. 6 shows the light module 1 as a sectional view in side view.

The cover 15 has a central recess 16 which, in plan view, corresponds approximately to the shape of the recess 3 of the circuit board 2. An outer side edge 17 of the cover 15 is folded downwards or backwards in the manner of a fold and can thus be pulled over the outer edge 4 of the circuit board 2 all the way around. Locally flattened partial areas 17a of the side edge 17 are used for correct angular alignment of the cover in correspondingly flattened areas of the outer edge 4 of the printed circuit board 2.

The cover 15 has a comparatively narrow and flat circular bulge 18 which bulges over the LEDs 8 or 8a, 8b. The cover 15 also has a bulge in the form of a comparatively wide and upstanding annular region 19 which bulges over the electronic components 9, 10. The raised area 19 is therefore noticeably higher than the bulge 18. The raised area 19 provides a large volume for accommodating the electronic components 9, 10, in particular if these do not have a low overall height, e.g. capacitors. The cover 15 rests on the circuit board 2 between the upstanding area 19 and the bulge 18.

In order to avoid shading the light emitted by the LEDs, the raised area may have a slope 20 towards the outside or in the direction of the bulge 18.

The cover 15 is locked with the locking sleeves 13 for attachment to the circuit board 2. She points to the Cup-shaped depressions 21 introduced on the upper side of the upstanding area 19, in the side walls of which several load hooks or latching straps 22 are integrated. The recesses 21 extend in the direction of the printed circuit board 2. The latching tabs 22 engage in the latching sleeves 13 in a latching manner. A bottom of the depressions 21 is open and thus represents a hole.

A plurality of fastening areas in the form of receptacles 25 are present on an outer side wall 24 of the upstanding area 19. The receptacles 25 are distributed in the circumferential direction, in particular distributed equidistantly, arranged and extend to an upper side 26 of the upstanding area 19. They have an insertion section 25a reaching up to the upper side 26 and a transverse section 25b extending therefrom. A corresponding insert can first be inserted into the plug-in section 25a and then screwed into the transverse section 25b, e.g. similar to a plug / turn movement of a bayonet connection.

Similar receptacles 25 are also present in the area of an inner side wall 27 of the upstanding area 19.

In the upper side 26 of the upstanding area 19, push buttons 28 are also integrated, which here are integrated into the cover 15 as elastically deflectable tabs. These can, for example, actuate electrical or electronic buttons or switches arranged there in the event of a deflection in the direction of the printed circuit board 2 or may release a cable clamp or the like (for example as embodied here). For the cable connection, several channels 29 leading inwards through the cover 15 are provided on the inner side wall 27 in the area of the pushbuttons 28. In particular, at least one electrical supply line, which runs through the central cutout 3 and 16, can simply be routed under the cover 15 to the printed circuit board 2. The at least one channel 29 enables safety clearances to be maintained and a connection that is particularly easy to assemble due to its guidance.

On the printed circuit board 2 and / or on the cover 15 there may be at least one strain relief for at least one electrical supply line, e.g. an electrical cable.

The cover 15 may also have depressions 37, in the bottom of which there is a longitudinal hole 38. A longitudinal hole 38 is aligned above a longitudinal slot-like recess 6 in the circuit board 2. The longitudinal hole 38 and the recess 6 allow a fastening element to be passed through, e.g. a screw, for example for fastening the light module 1 to a fastening adapter or directly to a wall or ceiling. Due to the elongated shape, the light module 1 can be variably positioned by shifting it sideways.

Fig. 7 shows, as a sectional illustration in a view obliquely from above, a detail of the light module 1 in the area of a snap-in sleeve 13, shown cut open, which is inserted into the hole 14 in the circuit board 2. The locking sleeve 13, which is made of metal, for example, has a continuous channel 30 through which a screw S is guided here. A head of the screw S rests on the locking sleeve 13. On an outer jacket surface of the locking sleeve 13 there is a circumferential locking projection 31 which is formed by means of an annular groove 32 made in the outer jacket surface. The other side of the annular groove 32 serves as a stop against the printed circuit board 2. The latching tabs 22 of the recess 21 of the cover 15 engage behind the latching projection 31 or engage the annular groove 32 so that the cover 15 is held on the printed circuit board 2 via the latching sleeve 13 will. The screw S may be used, for example, to fasten the light module 1 via its rear side R, for example directly on a wall or ceiling, or for fastening rear additional modules or additional parts.

Fig. 8 shows a section of the light module 1 in the area of the pushbutton 28 as a sectional illustration in an oblique view from above.

The pushbutton 28 is formed by cuts in the upper side 26 of the upstanding area 19 and has an operating area 33 that can be pressed in by a user. The operating area is connected to an elastically deformable bar or bending area 34 which provides the elastic restoring force when the operating area 33 is pressed in. A plunger area 35 protrudes from an underside of the operating area 33 in the direction of the printed circuit board 2. A clamping element 36 (e.g. a terminal strip) is attached to the printed circuit board 2 below the plunger area 35. If the plunger area 35 presses on the clamping element 36, the associated clamping contacts are opened.

Electrical feed lines are supplied to the terminal contacts of the clamping element 36 via channels 29 which are present on the inner side wall 27 and which lead through the cover 15. In particular, at least one electrical supply line, which runs through the central cutout 3 and 16, can simply be guided into the cover 15 to the clamping element 36. The at least one channel 29 extends as far as the clamping element 36 and enables safety clearances to be maintained and a connection that is particularly easy to assemble.

Fig. 9 shows a further possible cover 39 of the light module 1 in a view obliquely from above. The cover 39 is constructed similarly to the cover 15, but now has no circumferential curvature 18, but rather individual optical areas 40 arranged in a ring.

These cover only a single LED 8 or connected groups of LEDs 8a, 8b. The optical regions 40 enable beam formation to be better adapted to the LEDs 8 or 8a and 8b. Like the optical areas 40 for example, be beam-shaping, for example by being designed as diffuser areas or as lens-like areas.

Fig. 10 shows in a view obliquely from above yet another possible cover 41 of the light module 1. Instead of the bulge 18, a further, larger bulge 42 is now provided, which serves as a diffuser. In this way, a particularly homogeneous light emission can be achieved.

The above light modules 1, 1 and 15, 1 and 39, 1 and 41 or 61 may themselves be used as lights.

Fig.11 shows the light module 1 according to the first exemplary embodiment as a sectional illustration in a view obliquely from above with a fastening adapter 43 attached to the rear. This combination 1, 43 may already be used as a (first) light L1. Fig.12 shows the fastening adapter 43 in a view obliquely from above.

The fastening adapter 43 may be designed, for example, for fastening the light module 1 to a wall or a ceiling. It may also be designed as a hanging lamp for the use of the light module 1.

The fastening adapter 43 has a closed circular ring shape with an inclined side wall 44 and a central recess 45 in its bottom 46. This can also be viewed as a shell shape that is open at the bottom. From an inner edge 47 of the base 46 a partition wall 48 extends upwards, to be precise at least approximately, specifically precisely, up to a height of an outer edge 49 of the side wall 44. In the partition wall 48 there are two inner recesses 50 for a passage of at least one electrical supply line provided, as well as two outer recesses 51 in the side wall 44 at the same circumferential angle, possibly for the same purpose. In front of the inner recesses 50 there are fastening areas 52 projecting into the recess 45, which can be used, for example, to relieve strain on the electrical supply line.

In addition, there are two vertically continuous channels 54 in the bottom 46, which are aligned with the longitudinal slot-like recesses 6 in the circuit board 2 and with the longitudinal holes 38 of the cover 15, so that a transverse displacement of the components 1, 43 or the lamp L1 against the mounting adapter 43 is made possible.

In addition, laterally guided longitudinal holes 53 are introduced. The side wall 44 is connected to the partition wall 48, for example to increase stability, by radially extending transverse ribs 55.

Fig. 13 in a view obliquely from above or from the front, a cover 62 of a light module 61 according to a second exemplary embodiment. Fig. 14 shows the light module 61 in a view obliquely from below or from the rear with the cover 62 and a printed circuit board 63 fastened therewith.

The cover 62 again has a circular basic shape, an inner recess 64 now having a rectangular basic shape, while an outer edge 65 is at least substantially circular. Distributed on the outer edge 65 are three inwardly directed latching or snap-in areas 66 which can hold the printed circuit board 63 locked by wrapping around its outer edge 66. Additionally or optionally, depressions 21 in the cover 62 and locking sleeves 13 on the circuit board 21 can also be provided for locking, as already described above.

At the in Fig. 13 The front side of the cover 62 shown is the bulge 18, which arches over the LEDs, which are ring-shaped on the outer portion of the circuit board 63 are arranged. There is also an inner, upstanding, annular area 67 which arches over electronic components located on an inner partial area of the printed circuit board 63. The upstanding area 67 has a plurality of fastening areas in the form of latching receptacles 69 in the area of its outer side wall 68. The latching receptacles 69 are designed here as simple undercuts or latching receptacles, for example to be brought into engagement with latching hooks. The latching hooks can be inserted into the latching receptacles 69 by means of a simple plugging movement.

The cover 62 also has a push button 28 for releasing a cable clamp or the like in order to be able to insert or release electrical leads that are guided through a plurality of channels 29.

The cover may also have at least one hole or recess 70, for example for access to operating elements such as potentiometers that are located on the circuit board 63.

On an underside of the cover 62 within a recess 71 of the printed circuit board 63 there is an area 72 for strain relief of at least one electrical supply line.

Fig.15 shows, in a view obliquely from above, a sectional illustration of a light module 1 provided with two add-on units or additional modules 72 or 73. This combination 1, 72, 73 may be used as a (second) light L2. The first additional module 72 is designed as a translucent or opaque circular ring-shaped diffuser cover which covers the bulge 18 and homogenizes the light emitted by the LEDs 8 or 8a and 8b. The first additional module 72 may, for example, be fastened to the receptacles 25 of the outer side wall 24 of the upstanding area 19. The second additional module 73 may be an opaque cover plate which covers the upstanding area 19 and provides a view of the electronic components 9, 10 largely denied. The second additional module 73 may be fastened to the receptacles 25 of the inner side wall 27 of the upstanding area 19.

Alternatively, instead of the two additional modules 72 and 73, a single, combined additional module may be used, which is manufactured in one piece and combines the functions of both additional modules 72 and 73. Such an additional module may be manufactured using two-component injection molding, e.g. with a translucent or opaque area and an opaque area.

Fig. 16 shows in a view obliquely above a sectional view of a light module 1 provided with another additional part in the form of a metallic back plate (which is also referred to below as "back plate" 74). This combination 1, 74 may be used as a (third) light L3 will. Fig.17 shows the luminaire L3 in part in an oblique view from below.

The annular rear plate 74 is arranged on the rear side R of the printed circuit board 2. It covers the circuit board 2 and protrudes laterally beyond it. The rear plate 74 improves the cooling of the LEDs 8 or 8a, 8b and the electronic components 9, 10.

The rear plate 74 has a central recess 75 which corresponds approximately to the recess 3 of the circuit board 2 and thus leaves the connection space free. The back plate 74 has holes 76 provided with a thread pull, by means of which it is screwed to the circuit board 2 and the cover 15 by means of the screws S guided through the locking sleeves 13.

The rear plate 74 has recesses 78 on its inner edge 77 in the region of the channels 29 of the cover 15 in order to maintain electrical safety clearances.

The lamp L3 can be fastened by means of screws S2 guided through the longitudinal holes 38 and the respective recess 6, e.g. on a wall or ceiling or on a mounting adapter (e.g. 43) or similar.

Fig. 18 shows, in a view obliquely from below, yet another additional part in the form of a diffuser cover 79 for the luminaire L3 or the combination 1, 74. The diffuser cover 79 is designed in the shape of a circular ring with a central recess 80. At an inner edge 81 surrounding the central recess 80, a circumferential wall ("fastening wall" 82) which is interrupted several times extends downwards or to the rear. The fastening wall 82 has several fastening elements 83 projecting inwardly into the recess 80 in an L-shaped cross-section and several snap or latching hooks 84 projecting outward with their lugs. An outer edge 85 is folded over downwards or backwards, for example in the manner of a fold, in order to encompass an outer edge 86 of the back plate 74.

Fig. 19 shows an additional part in the form of a reflector ring 80 for the front cover 79 in an oblique view from above. An outer side 87 of the reflector ring 80 is designed to be reflective.

Fig. 20 shows in a view obliquely from below the front diffuser cover 79 with the attached additional part 80. For this purpose, the reflector ring 80 rests with its larger edge 88 on the diffuser cover 79 or on its circular wall 90 and is attached to its smaller edge 89 by the locking hooks 84 latching behind. A secure, positive fit of the ring reflector 20 on the cover 79 can thus be achieved by means of a simple push-on movement.

The fastening elements 83 are used to fasten the parts 79, 80 assembled in this way to the receptacles 25 of the cover 15 on the outer side wall 24 of the upright Area 19 by means of a plug / turn movement, as in Fig. 21 shown. After the parts 79, 80 have been attached to the cover 15. This combination L3, 79, 80 or 1, 74, 79, 80 may also be viewed as a (fourth) lamp L4.

Fig. 22 shows the luminaire L4 in detail as a sectional illustration in a view obliquely from above. The reflector ring 80 arches over the bulge 80 and thus also the LEDs 8 or 8a, 8b, specifically in such a way that it is located from the cover 15 to the diffuser cover 79 spaced forward therefrom. As a result, the light emitted by the LEDs 8 or 8a, 8b is partially radiated onto the reflective outer side 87 of the reflector ring 80 and from there onto the back plate 74. The back plate 74 is reflective, in particular diffuse, in at least one area of its front side that can be illuminated by the light designed reflective, for example by a white coating, for example made of titanium oxide. The light reflected onto the back plate 74 is emitted to the outside through the transparent diffuser cover 79 at a wide angle and with its intensity and / or color distribution uniform. In this way, the circular wall 90 can be illuminated practically homogeneously and even let light through in this way. So that the LEDs 8 or 8a, 8b do not protrude too strongly in terms of light technology, the diffuser cover 79 is designed with a relatively large distance from the LEDs.

The rear plate 74 has a curvature 91 in the area of the outer edge 85, which prevents light from escaping from the side and guides the diffuser cover 79 circumferentially during assembly. The curvature 91 is formed as an embossing in the rear plate 74 that is directed forwards (in the direction of the diffuser cover 79). Light reflected at the bulge 91 is directed, in particular, to the front onto the diffuser cover 79 and may produce a light ring that shines slightly brighter there. By varying the shape, in particular the course, of the bulge 91, the shape of the Light ring can be changed, e.g. into a spiral, a ray pattern etc.

In order to prevent the reflector ring 80 from casting a visible shadow edge (which runs through a straight line from the LEDs 8 or 8a, 8b to the larger edge 88 of the reflector ring 80), this shadow edge is converted into a step 92 in the wall 89 of the Diffuser cover 79 placed.

The luminaire L4 enables a large-area, flat structure based on the light module 1.

A circular cover disk 93 can also be attached to the luminaire L4, which is shown in FIG Fig. 23 is shown. The cover plate 93 may consist of an opaque material or it may be so strongly opaque or translucent that a viewer cannot visually perceive parts and / or structures of the light L5 arranged behind the cover plate 93, but at best as a scheme. The highly opaque cover plate 93 has the advantage that it allows light to be guided.

The cover plate 93 may, however, also be made transparent, for example, whereby an insert plate (not shown) can be inserted on an underside of the cover plate 93. A small part of the light generated by the LEDs 8 or 8a, 8b may also be directed particularly effectively in the direction of a center of the cover plate 93 and thus also a center of the luminaire, so that it does not remain dark. The cover plate 93, in particular the insert plate, may be personalized, for example, with regard to its color, possibly lettering or also materiality (fabric, wallpaper, etc.).

The cover plate 93 may be designed for the attachment of further elements, for example information elements, for example made of light-conducting material.

In order to prevent reflections on a cover plate 93, in particular a transparent cover plate, this cover plate can be formed in a slightly arched manner.

On its rear side facing the printed circuit board 2 and the cover 15, the cover disk 93 has several L-shaped fastening elements 94 for engaging in the receptacles 25 in the area of the inner side wall 27 of the upstanding area 19 or on the diffuser cover 79. The cover plate 93 may in particular be mounted after the diffuser cover 79 and partially cover it.

Fig. 24 shows the arrangement in a view obliquely from above Fig. 21 with the cover plate 93 Fig. 23 . Such an arrangement L4, 93 can also be viewed as a lamp L5. Fig. 25 shows the luminaire L5 as a sectional view in an oblique view from above.

Fig. 26 shows a section from the arrangement in a view obliquely from above as a sectional illustration Fig. 24 . The cover plate 93 covers the diffuser cover 79 above the circuit board 2. For this purpose, the cover plate 93 has in particular an outer edge area 95 which covers an inner edge area of the diffuser cover 79, which extends from the step 92 to the fastening wall 82. In particular, this outer edge area 95 may be treated so as to be opaque in order to prevent a view of the inner edge area of the diffuser cover 79. For this purpose, the cover plate 93 may be satined or partially satined on its outer edge area 95, for example. A surface of the outer edge region 95 of the cover plate 93 may additionally or alternatively be partially painted or partially vapor-coated, so that part of the light is transmitted radially inward (towards the center of the luminaire).

The diffuser cover 79 can protrude upwards or forwards, so that the diffuser surface protrudes in height beyond at least an outer ring area of the cover disk.

Although the invention has been illustrated and described in more detail by means of the exemplary embodiments shown, the invention is not restricted thereto and other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention.

In general, “a”, “an” etc. can be understood to mean a singular or a plurality, in particular in the sense of “at least one” or “one or more” etc., as long as this is not explicitly excluded, for example by the expression “precisely” a "etc.

A numerical specification can also include exactly the specified number as well as a customary tolerance range, as long as this is not explicitly excluded.
