The invention relates to an automobile lighting technology, in particular to a light guide structure for solving large-area light emission and a signal lamp. The light guide structure comprises a reflector, a light guide and a PCB, wherein one end of the light guide is connected with the PCB. The light guide structure further comprises a fixing mechanism, a light guide buckle, light guide back teeth, light guide side teeth and a light guide piece connecting piece, wherein the light guide is connected with the reflector through the fixing mechanism, the light guide is further connected with the reflector through the light guide buckle, the light guide is connected with the reflector through the light guide piece connecting piece, tooth-shaped structures are arranged on the back surface and the side surface of the light guide, light passing through patterns on the back surface is emitted towards the X direction, light passing through patterns on the side surface is emitted towards the other side of the light guide, and the light emitting range of the light is expanded through diffusion of the reflecting surface, so that the problem of large-area light emission of the light guide structure is solved, the cost is saved, the application of the light guide in the field of signal lamps is improved, the light guide is combined with an inner lampshade with dermatoglyph on the inner surface, the light diffusion effect can be further achieved, the uniformity of the overall function is achieved, and the lighting effect similar to a light band is obtained.
Description
Technical field [0001] The present invention relates to an automotive lighting technique involving a light guide structure and a signal lamp thereof that solves a large area of light. Background technique [0002] The development of the car photographic field, the shape of the lamp is increasing, and the light surface size and shape are gradually broken through the tradition. The traditional large-area light exposure surface is realized using the LED to reflect the mirror, and the litter is strong, and the number of LEDs is large. The use of the light guide structure can reduce the number of LEDs and the light surface is more uniform, and the lighting effect can be reduced while the lighting is reduced, and the lamp is currently widely used in the field of light. However, the area of the permanent light guide is often smaller, and the application of the light guide is limited to the field of large-area styles. Inventive content [0003] The technical problem to be solved by ...
