Determine slot to be fixedly connected with anti-skid cover.
As advanced optimizing for the technical program, a kind of optical lens with free curved surface of the present invention, the base is organic
The photic zone of material production is made every effort to overcome in the base of glass production, the photic zone Asia, and the refracting layer is the folding of quartz glass production
Penetrate layer.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
1. there is stronger light transmission by photic zone, so as to enhance the translucency of lens, in order to promote light source pair
External radiation response, it is more practical, and the light transmittance of lens can be effectively promoted by filtering blu-ray layer, while can cover
The blue light that light source comes out prevents people when carrying out viewing light source, avoids damaging people's eyes, greatly be promoted
The practicabilities of lens.
2. the refracting layer made by quartz glass, keeps light more uniform in the refraction track of lens interior, is not easy out
Existing intricate phenomenon, avoids the use for influencing people to lens, is wherein fixed with concave surface at the top of refracting layer, makes light
There is good diffusivity in lens interior, so as to promote light source to external irradiated area.
3. good protection can be carried out to lens by making every effort to overcome release film by Asia, lens surface is set to be less prone to destruction, greatly
Big improves the service life of lens, wherein good reflection can be carried out to light source by reflective layer, so as to be promoted
The utilization rate of light source, avoids light source from being wasted.
A kind of optical lens with free curved surface of the present invention program, novel in design, structure is simple, has good light transmission effect
Fruit, while can effectively increase the irradiated area of light source, secondly, having certain anti-dazzle effect, do not easily cause light pollution
Phenomenon, it is more practical, it is suitble to be widely popularized and used.
Detailed description of the invention
Technical scheme of the present invention is further explained with reference to the accompanying drawing：
Attached drawing 1 is a kind of overall structure diagram of optical lens with free curved surface of the present invention.
Attached drawing 2 is a kind of lens interior structural schematic diagram of optical lens with free curved surface of the present invention.
Wherein：Lens 1, shield 2, base 3, photic zone 4, filter blu-ray layer 5, refracting layer 6, concave surface 7, anti-dazzle layer 8, thoroughly
Bright raised 9, release film 10, fixing groove 11, rubber layer 12, reception room 13, reflective layer 14, through slot 15 are made every effort to overcome in Asia.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
