Description

Thick wall extinction structure of car light Technical Field The utility model relates to the technical field of car lamps, in particular to a thick-wall extinction structure of a car lamp. Background The thick-wall part of car light is the core optical carrier of car light, is made by transparent material usually, and the main role is that the conduction light can set up the decorative frame in the thick-wall part outside generally, through the fixed and decoration part of decorative frame, except for providing stable support for the thick-wall part, can also play shelter from inner structure, optimize the effect of car light outward appearance. Along with the daily and lunar variation of car lamp modeling, the modeling concept of thick wall external leakage outside the decorative frame has begun to lead trend, but because the size of thick wall spare external leakage outside the decorative frame is too much, when light conducted in the thick wall spare, the side wall can produce bright spots about the thick wall spare, and bright spots can influence car lamp thick wall and light effect and whole pleasing to the eye, remain to optimize. Disclosure of utility model Aiming at the problems, the utility model provides a thick-wall extinction structure of a car lamp, which is used for solving the existing defects. The thick-wall extinction structure of the car lamp comprises an extinction grain A arranged on the outer side of a thick-wall part, wherein one end of the thick-wall part is provided with an incident surface, the other end of the thick-wall part is provided with a light emitting surface, the incident surface is provided with a condenser, and a path from the incident surface to the light emitting surface forms a light transmission path; The extinction texture A comprises at least one blocking groove, the blocking groove is formed in the upper side wall and the lower side wall of the thick-wall piece, a rib plate is arranged on one side of the blocking groove, the rib plate is fixedly connected with the thick-wall piece, and the extending direction of the blocking groove and the rib plate is not collinear with the light transmission route.
