Description

car tail light

technical field

The utility model belongs to the technical field of vehicle lamps, in particular to an automobile tail lamp.

Background technique

Car tail lights are usually installed at the rear of the car body for night lighting to remind vehicles behind to keep a safe distance. In order to ensure the lighting effect of automobile taillights, LED light sources are commonly used in existing automobile taillights. However, due to the Lambertian luminous characteristics of LED light sources, the brightness near the center of the LED will be higher, and the position far away from the LED lights will produce dark areas. , resulting in uneven lighting and affecting the lighting effect.

In order to solve this problem, some automobile manufacturers install the LED light source on the thick-walled light guide structure. A light guide structure and an LED light source installed inside the thick-walled light guide structure. Since the tail end of the thick-walled light guide is equipped with a microstructure of the reflective surface, the light in the central area can be diffused at a certain angle according to the light-emitting angle characteristics of the LED, and the light on both sides can be collimated, so that the light-emitting area of the thick-walled light guide has a Uniform incident light, realize the uniform transmission of light in the thick-walled parts, and improve the lighting effect.

In the above technical solution, the taillights located on the left and right sides of the rear of the car generally include two lampshades arranged left and right with a gap in the middle, each lampshade is provided with a thick-walled light guide block and an LED light source, and the thick-walled light guide block will be located on the other side. The light emitted by the LED light source on the inside spreads to the outside. However, there are large dark areas in the gap between the two lampshades and between each thick-walled light guide block and the side wall of the corresponding lampshade facing the other lampshade, which directly affects customers. The poor visual senses caused customers to complain about the problem, which needs to be improved urgently.

The horizontal part is connected to the outer surface of the corresponding thick-walled light guide block, so that the upper surface of the thick-walled light guide block is inclined downward from the inner side to the outer side, so as to ensure the light-emitting area of the taillight and improve the visual perception of customers.

In the above automobile tail light, the upper surface of the protrusion is flush with the corresponding horizontal part. It is conducive to improving the streamline effect of lighting and improving customers' visual senses.

In the above automobile tail light, the protrusions are in a square shape, and there is a gap two between each protrusion and the side wall of the corresponding lampshade facing the other lampshade. The bump is square, which is convenient for mold design and preparation, and can ensure the light-emitting surface area of the bump. The second gap facilitates the installation of the thick-walled light guide block in the lampshade, and can avoid light interference between the bump and the lampshade to ensure the lighting effect of the bump, thereby helping to reduce light and dark areas.

In the above-mentioned automobile tail light, the protrusion is integrally formed with the corresponding thick-walled light guide block. The installation stability of the bump can be ensured, and at the same time, the design and preparation of the mold are facilitated, and the production cost is reduced.

Compared with the prior art, the utility model has the following advantages: a transparent bump is set on the side wall of the thick-walled light-guiding block facing the other thick-walled light-guiding block, so that the light in the thick-walled light-guiding block can pass through the bump , the light-emitting area of the thick-walled light-guiding block is increased, and the bumps are arranged close to the outer side of the corresponding thick-walled light-guiding block, and the light can be transmitted to the side of the thick-walled light-guiding block and the corresponding lampshade facing the other lampshade through the refraction of the transparent bumps The area between the walls can effectively reduce the light and dark areas of the car taillights and improve the visual sense of customers.
