Description

Technical Field

[0001] The utility model relates to the field of vehicle lamps, in particular to an automotive rear position lamp. Background Art

[0002] In the automotive field, different types of vehicles have different types of lights. The lights at the front of the vehicle include front outline lights, outline lights, high and low beam lights, turn signals, and fog lights. The lights at the rear of the vehicle include rear position lights, brake lights, reverse lights, turn signals, and license plate lights. These lights play an indispensable role in the vehicle. When it comes to vehicle lights, the rear position lamp is an important component. The rear position lamp is also known as the width indicator lamp, and its main function is to indicate the presence and width of the vehicle, facilitating other vehicles to judge the width of the vehicle when meeting or overtaking. The rear position lamp is usually located at the front edge or the rear edge of the vehicle. Like buses or large trucks, width indicator lights are installed on the roof and sides. When driving at night, the rear position lamp can play an important role in helping other vehicles judge the width of the vehicle, facilitating entry or overtaking. In addition, the rear position lamp can also be used as a brake light to remind the following vehicle that the braking measure has been taken. The existing rear position lamp only has the functions of on and off, lacking innovation and interaction with people. Summary of the Invention

[0008] As an improvement, the mask is a black or smoky gray translucent mask.

[0009] The beneficial effects brought by the present utility model compared with the prior art are as follows:

[0010] 1. The LED light source is composed of a plurality of light-emitting units spliced together, which can reduce the heat concentration of the LED lamp beads distributed in an array. The lamp board is supported and fixed on the support plate by the second bolt columns, and a heat dissipation channel is formed between the two, which is beneficial to the heat dissipation of the lamp board;

[0011] 2. The LED lamp beads on each lamp board are uniformly controlled by a program, and a unique light-emitting pattern can be realized when lit. The vehicle owner can customize the position lamp pattern according to his own preferences, personality or specific theme, making the vehicle more unique and eye-catching on the road, and meeting the individual aesthetic and expression needs;

[0012] 3. The unique customized pattern can improve the recognition of the vehicle at night or under low visibility conditions, reduce the risk of traffic accidents, and other road users can more easily identify and distinguish different vehicles. BRIEF DESCRIPTION OF THE DRAWINGS
