Car taillights, including lamps and bulbs in the tail of the car. Among them, the function of the lamp is to aggregate and emit the light emitted by the bulb, so as to enhance the brightness and range of the light emitted by the bulb and change the light color of the bulb through the color of the lamp. There are currently three main types of bulbs, one is halogen car bulbs, the other is HID car bulbs, and the emerging LED car bulbs.
LED taillights are innovative brake lights and taillights that use long-term LED light sources. The light bulb is made of diodes, the brightness is higher than ordinary light bulbs, and the response speed is faster. LED (Light-Emitting-Diode in Chinese means light-emitting diode) is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament light emission of incandescent lamps and three-primary color powder light emission of energy-saving lamps, and electroluminescence is adopted. It can send signals to other vehicles and pedestrians when the car brakes, turns or turns. LED taillights have excellent light source intensity and can maintain extremely high visibility even in foggy weather.
In recent years, due to the needs of design, aerodynamics and aesthetics, the low-profile, streamlined appearance of automobiles has become more and more popular. The shape of the taillights is also developing towards heterogeneity and integration. According to the application, automotive LED lights can be divided into light distribution lamps and decorative lamps. The light distribution lamps are suitable for instrument indicator backlight display, front and rear turn lights, brake indicators, reversing lights, fog lights, reading lights, etc. On the one hand, decorative lights are mainly used to change the color of car lights, which can beautify the interior and exterior of the car. In recent years, as the brightness problem of some vehicles has been solved and the cost has dropped, its application has increased.
