Automobile lamp optical system with optical thick-wall part

Abstract

The invention aims to provide an automobile lamp optical system with an optical thick-wall part. A middle plane can be adjusted in the horizontal direction and in the longitudinal direction, and lightof an LED light source enters the optical thick-wall part through a collimator to reach the middle plane of the optical thick-wall part. On the one hand, one part of the light is adjusted by a longitudinal cross section of the middle plane, is completely reflected and reaches a bottom light-emitting surface; on the other hand, the other part of the light is adjusted by a transverse cross sectionof the middle plane and broadened in the horizontal direction; and finally, the light is adjusted in the horizontal direction and in the longitudinal direction and emitted from a pattern surface whichis diffused at the bottom. The collimator is used for feeding light, so that the effect of improving the light effect is achieved. The middle plane with a bidirectional adjusting mechanism is used, the light is completely reflected in the longitudinal direction to reach the bottom light-emitting surface, and the light is broadened in the horizontal direction after being horizontally adjusted so that the horizontal width of the bottom light-emitting surface can be larger than the horizontal width of a top light incident surface, and the problem about saving and compacting space of a PCB is solved.

Description

technical field [0001] The invention relates to the field of automobile headlight optical systems, in particular to an automobile headlight optical system for optical thick-walled parts. Background technique [0002] With the rapid development of automobile lamp technology, in addition to the design of lamps that can strictly meet the requirements of regulations, vehicle customers are paying more and more attention to the appearance requirements of lamps, especially the lighting effect. To a certain extent , a beautiful appearance of headlights can quickly improve the visual experience of a car. For car lights, customers like the novel design of the lights and the perfect lighting effect. Therefore, more and more thick-walled parts are used in automobile lights, which have reached the requirements of transparency, uniformity and changeable shapes. [0003] Although the existing thick-walled parts can meet the requirements of vehicle customers for the shape and appearance o...
