Abstract

The invention relates to the technical field of car lamps, especially to a reflector structure and a car lamp. Light distribution patterns are arranged on the side wall of the reflector; the light distribution patterns comprise first visual angle patterns and second visual angle patterns; the first visual angle patterns are corn kernel patterns which are uniformly distributed; the second visual angle patterns are strip-shaped patterns; the light directly emitted or reflected to the side wall by the LED light source is reflected by the first visual angle patterns to form light rays of 50-80 degrees; and light directly emitted by the LED light source or reflected to the side wall is reflected out of 30-60 degrees of light through the second visual angle patterns. The reflector structure andthe car lamp can solve the problem that in the prior art, an automobile lamp cannot meet the requirement for a large-angle visual angle.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, and specifically relates to a reflector structure and a vehicle lamp. Background technique [0002] Automobile lamp regulations require that some functions of lamps, such as turn signals and position lamps, need to meet the requirements of a large viewing angle of 45° on the inside and 80° on the outside. At present, reflective car lights still occupy a large proportion in the field of automotive lamps due to their simple structure. The large-angle light of reflective lamps is reflected by the LED light source through the side wall, but the reflection efficiency of the side wall of the reflector is very low. Some cannot achieve the wide angles required by car lighting regulations. With the changeable shape, the light emitting surface of reflective car lights becomes smaller, and the area of ​​the side wall of the reflector that can be seen at large angles becomes smaller and smaller. The t...
