[0002] At present, when designing tail lamps, many cars use transparent thick-walled inner lampshades as the main light-emitting window of the lamp. The light emitted by the LED behind or above the thick-walled inner lampshade is transmitted to the thick-walled inner lampshade through the principle of reflection or refraction, and is emitted from the front of the thick-walled inner lampshade, thereby lighting up the function. At this point, the light source directly observed by people is transformed from the point light source of the LED to a surface light source mainly in the shape of the thick-walled inner lampshade.
[0003] On the other hand, with the popularity of horizontal through-type taillights in recent years, taillights are usually designed by designers to be long strips, which increases the horizontal size of the lamps while continuously compressing the vertical size. In the end, all major automobile manufacturers are faced with a structural problem: how to integrate the functions of position lights, brake lights, reverse lights, rear fog lights, logo lights and many other signal lights into the long strip taillights.
