Description

A kind of aspherics lens with section photo structure

Technical field

The utility model belongs to LED light lens technology, concretely relates to a kind of with the non-of section photo structure Spherical optical lens.

Background technique

LED light source is widely used in various illumination occasions due to its characteristic better than conventional light source.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 certain shapes and matching for degression type Therefore light will install again an optical lens 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.

Summary of the invention

The purpose of the utility model is to provide a kind of with the aspherics lens for cutting photo structure, is intended to solve existing Many deficiencies present in technology.

In order to solve the above technical problems, purpose of the utility model is realized as follows:

A kind of aspherics lens with section photo structure, including non-spherical lens and reflection box, the reflection box Framework comprising four directions, the unilateral section of framework are triangle, and the non-spherical lens is located at the framework center, institute Stating reflection box inner surface is wide-mouth shape, 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 above scheme and as above scheme: the framework bottom has a bottom plate, institute It states aspherical lens base to blend with the bottom plate, so that reflection box and non-spherical lens is formd an entirety 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 above scheme and as above scheme: 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 above scheme and as above scheme: 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, High production efficiency, light, drop resistant, reflective layer is for being intercepted and being reflected the light projected by non-spherical lens, aspheric Face lens make LED circular light spot 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 above scheme and as above scheme: the framework material be acrylic with it is reflective Material granule mixture is mixed with reflectorized material particle in acrylic, make its after shaping entire framework all become one it is reflective 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.

Compared with the prior art, the utility model has prominent and beneficial technical effects that: non-spherical lens makes LED circular light spot It is changed into 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 With sharp keen section change rectangular illumination spot, preferably remove veiling glare, dazzle, obtain better optical field distribution.

Specific embodiment

To keep the purposes, technical schemes and advantages 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, the unilateral section of the framework 31 is triangle, and the non-spherical lens 20 is located at the frame 31 center of body, 31 inner surface of reflection box are wide-mouth shape, and wide-mouth direction goes out light with 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 framework has a bottom plate 32,20 bottom surface of 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 framework is acrylic and its wide-mouth surface is coated with reflective layer 33.

Certainly, 31 material of framework can also be acrylic and reflectorized material granulate mixture, and reflectorized material is existing Common reflectorized material in technology.

Embodiment two

Difference with embodiment one is reflection box 30 and non-spherical lens 20 is split type structure, right in actual use The two is assembled.

Specific principle are as follows:

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, thus It realizes other colour switchings such as RGB, forms it into rectangular colored hot spot.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
