Abstract

The invention discloses a kind of aspherics lens for having and cutting photo structure, including non-spherical lens and reflection box, the reflection box includes the framework in four directions, the unilateral section of framework is triangle, the non-spherical lens is located at the framework center, the reflection box inner surface is wide-mouth shape, its wide-mouth projects light mutually its light direction reflection in the same direction and by the non-spherical lens towards the light-emitting surface with the non-spherical lens, the light of LED light source is after non-spherical lens transmits, it intercepts and reflects using reflection box, there is sharp keen section of change square focus spot to obtain, the rectangular illumination spot uniformly with sharp keen section of change may be implemented in it, preferably remove veiling glare, dazzle, obtain better optical field distribution.

Description

It is a kind of that there are the aspherics lens for cutting photo structure
Technical field
The invention belongs to LED light lens technologies, concretely relate to a kind of with the aspherical of section photo structure Optical lens.
Background technology
LED light source is widely used in due to its characteristic better than conventional light source in various illumination occasions.Current LED light Source is made of the spherical lens of LED chip and the closing LED chip, and in order to remove veiling glare, dazzle so that LED light source Luminescent properties are more preferable, obtain better optical field distribution, need light-ray condensing into the hot spot of definite shape and matching for degression type Therefore light will install an optical lens again on LED light source.
Present LED lamp design is unreasonable, causes its condenser performance not high, cannot effectively remove veiling glare, dazzle, not have The original intention for reaching mounted lens forms the problems such as luminous irregular, dazzle is big and causes inconvenient for use.
In addition, existing section of photo structure is often designed as reflector, but reflector is only applicable to relay lens, for non- Spherical lens is simultaneously not suitable for.
Invention content
The object of the present invention is to provide a kind of aspherics lens for having and cutting photo structure, it is intended to solve the prior art Present in many deficiencies.
In order to solve the above technical problems, the object of the present invention is achieved like this:
It is a kind of that there is the aspherics lens for cutting photo structure, including non-spherical lens and reflection box, the reflection box Include the framework in four directions, the unilateral section of framework is triangle, and the non-spherical lens is located at the framework center, institute It is wide-mouth shape to state reflection box inner surface, and wide-mouth is in the same direction towards the light-emitting surface with the non-spherical lens and will be described aspherical Lens project light mutually its light direction reflection.
Preferred embodiment on the basis of said program and as said program:The framework bottom has a bottom plate, institute It states aspherical lens base to blend with the bottom plate, so that reflection box is formd an entirety with non-spherical lens in this way, so just In installation, it is not necessary that reflection box and non-spherical lens relative position are adjusted.
Preferred embodiment on the basis of said program and as said program:The framework, bottom plate and aspherical Mirror is integrally formed, and is integrally formed the production being convenient for rapidly and efficiently, and its homogeneity of product is high.
Preferred embodiment on the basis of said program and as said program:The framework material is acrylic and it is wide Discharge surface has reflective layer, and acrylic is plastic macromolecule material, with the preferable transparency, chemical stability, easily molded, Production efficiency is high, light, drop resistant, and reflective layer is for being intercepted and being reflected the light projected by non-spherical lens, aspheric Face lens make LED circular light spots be changed into square focus spot, and reflection box makes the light and shade of square focus spot become sharp keen.
Preferred embodiment on the basis of said program and as said program:The framework material be acrylic with it is reflective Material granule mixture is mixed with reflectorized material particle in acrylic, and making it, entire framework is all reflective as one after shaping Body reduces the step of coating reflective layer in this way, and process is saved while realizing same purpose and effect, improves production effect Rate.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that:Non-spherical lens makes LED circular light spots change For square focus spot, reflection box makes the light and shade of square focus spot become sharp keen so that the application lens devices may be implemented uniformly to have There is the rectangular illumination spot of sharp keen section of change, preferably removes veiling glare, dazzle, obtain better optical field distribution.

Specific implementation mode
To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with the attached drawing in embodiment, to reality The technical solution applied in example is clearly and completely described,
Embodiment one
A kind of aspherics lens with section photo structure, including non-spherical lens 20 and reflection box 30, it is described anti- The framework 31 that frame 30 includes four directions is penetrated, 31 unilateral section of the framework is triangle, and the non-spherical lens 20 is located at the frame 31 center of body, 31 inner surface of the reflection box are wide-mouth shape, the light extraction of wide-mouth direction and the non-spherical lens 20 Face transmits light in the same direction and by the non-spherical lens 20, and mutually its light direction reflects.
Further, 31 bottom of the framework has a bottom plate 32,20 bottom surface of the non-spherical lens and 32 phase of bottom plate Fusion.
The framework 31, bottom plate 32 and non-spherical lens 20 are integrally formed.
Further, 31 material of the framework is acrylic and its wide-mouth surface is coated with reflective layer 33.
Certainly, 31 material of the framework can also be acrylic and reflectorized material granulate mixture, and reflectorized material is existing Common reflectorized material in technology.
Embodiment two
Difference lies in reflection box 30 and non-spherical lens 20 it is split structure with embodiment one, it is right in actual use The two is assembled.
Specific principle is:
See Fig. 5, the light of LED light source 10 is being intercepted and is being reflected by reflection box 30 after the transmission of non-spherical lens 20, As shown in Fig. 6 there is sharp keen section of change square focus spot to obtain.
In addition, this lens can individually correspond to single led use, multiple LED can be corresponded to single lens and are used, to It realizes other colour switchings such as RGB, forms it into rectangular colored hot spot.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore:It is all according to The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
