The utility model discloses a three main key point: firstly, after the light coupling that LED sent gets into the lens, take place the total reflection as far as possible high-efficiently on the wavefront cutting plane, make more light can propagate along lens long limit direction. And secondly, the tooth-shaped structure on the back of the lens is optimized as much as possible, so that more light rays can be emitted and totally reflected more uniformly through the tooth-shaped structure and irradiate each area on the front of the lens. Thirdly, the front columnar structure of the lens is adjusted as required, the columnar structure can enable light to be better diffused, the diffusion angle of the light in the space can be effectively adjusted through the relative angle between the columnar structure and the tooth-shaped structure on the back face of the lens, the requirement of a large visual angle on the outer side of a tail lamp function is met, and meanwhile the lightening effect of the glistening shark is achieved by matching the angle of the tooth-shaped structure.
The utility model has the advantages that: through reasonable placement of the LED and the lens and design of optical structures on the side surface, the back surface and the front surface of the lens, a common lens can be lightened according to different modeling requirements, so that a special lightening effect is obtained; the side surface of the lens has a total reflection collimation function, so that light rays emitted by the LED light source can be efficiently coupled into the lens for propagation; the back of the lens is provided with a tooth-shaped structure, and the tooth-shaped structure is designed according to the shape, so that light rays in the lens are totally reflected through the optimized tooth-shaped structure and are transmitted to each area needing to be lightened on the front of the lens.
