Abstract

The invention discloses an automobile tail lamp capable of achieving different functions in the same area. The automobile tail lamp capable of achieving different functions in the same area comprisesa circuit board, a first reflector, a second reflector, a lamp body, a light diffusion layer and a lens. The horizontal circuit board is arranged on the upper portion in the lamp body, a first LED light source and a second LED light source are arranged on the circuit board, the vertical light diffusion layer is arranged at the outer end of the circuit board, and the parallel lens is arranged on the outer side of the light diffusion layer. The first reflector and the second reflector are arranged under the circuit board, the first LED light source is located at the focal point of the first reflector, the second LED light source is located at the focal point of the second reflector, and the middle of the first reflector is hollowed out. By means of the automobile tail lamp capable of achieving different functions in the same area, different functions in the same area are achieved through two independent optical subsystems, the efficiency of a whole optical system is effectively improved,and uniformity of the whole illuminating effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile lamp bodies, in particular to an automobile tail lamp which realizes different functions in the same area and has a more uniform lighting effect. Background technique [0002] At present, LEDs are widely used in the exterior lamp body of automobiles, and more and more automobile manufacturers and customers choose to use all-LED exterior lamp body design. In the past, the large size of the bulb limited the shape of the car's exterior light body, and the filament of the bulb limited the possibility of implementing different functions in the same area, especially without color. Compared with light bulbs, LEDs have the advantages of small space requirements, which makes the shape of the exterior lamp body of the car more diverse and complex, and also provides a variety of choices and combinations for the definition of each functional area of ​​the lamp body. [0003] In the existing systems that r...
