Large-spacing, high-lighting-effect and small-size thick-wall light guide structure

Abstract

The invention provides a large-spacing, high-lighting-effect and small-size thick-wall light guide structure. The structure is matched with an LED light source in use, and is provided with total reflection optical surfaces and diffusion patterns. The diffusion patterns are arranged on the light-emitting slope face of the thick-wall light guide, the three total reflection optical surfaces are arranged on the other side face, and a 45-degree wedge surface is formed between every two total reflection optical surfaces. The design is skillful, and the structure is optimized. Collimation and diffusion patterns are added, so that the light rays can be uniformly diffused from each direction. Uniform light emitting of the whole thick-wall light guide can be achieved only by changing the physical structure of the thick-wall light guide and evenly distributing the optical structures on the thick-wall light guide. Primary total reflection and secondary total reflection of the light are achieved through reasonable distribution of the optical surfaces. The illumination distance is increased, the utilization efficiency of the LED light source is greatly improved, high practicability is achieved,and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of car lights and car light source adjustment, in particular to a thick-walled light guide structure with large spacing, high light efficiency and small volume. Background technique [0002] With the promotion of industrialization, cars have become an indispensable means of transportation in people's lives. The requirements and performance improvements of car lights are also constantly refined. Nowadays, in order to improve the lighting effect and lighting effect of car lights, people pay attention to the car The design requirements of lamps are getting higher and higher. [0003] In modern car shape design, the shapes are becoming more and more diverse, and the use of thick-walled light guide sheets on car lights is becoming more and more common. The thick-walled light guide structure distributes the light emitted by the LED lights evenly, turning the point light source of the LED light into a surface ligh...
