Description
技术领域technical field

Innovative reforms are essential in the fiercely competitive automotive sector. In order to comply with the policy of harmony, environmental protection and energy saving, automobile lamps are also developing towards a streamlined integration method: the design structure is improved, so that they have stronger competitiveness. The current car taillights generally choose LED as the directional light source. In any case, the combined light emission cannot achieve the original old-fashioned filament method. However, the design of the car taillight is to spread out from the center of the light, and gather the light emitted by the original tungsten wire to all directions through the reflective surface. It is almost impossible to use a directional point light source to project to the required place to achieve the illuminance at various angles of the automobile taillight safety standards. However, this invention uses a special structure to make the LED emit light at 360 degrees. According to the previous filament The light center reaches to completely replace the traditional taillights.
其次，还在汽车尾灯上安装反射镜在汽车尾灯中的主要作用：通过改变发光源所发射光线的路径，进而形成路面照明效果，以达到在光线不足的地区，保证安全驾驶。Secondly, the main function of installing the reflector on the taillight of the car is to change the path of the light emitted by the light source to form a road lighting effect to ensure safe driving in areas with insufficient light.
但是上述的汽车尾灯在使用时，LED等发出的光线直接向外侧照射，在车辆行驶的过程中，车尾灯的灯光直射伤及后车司机的眼睛且会在短时间内形成视线盲区，影响车辆的安全驾驶，因此，需要一种预防灯光直射的导光汽车尾灯满足使用需求。However, when the above-mentioned automobile taillights are in use, the light emitted by LEDs etc. is directly irradiated to the outside. During the running of the vehicle, the direct light of the taillights will hurt the eyes of the driver behind and will form a blind spot in a short time, affecting the vehicle. Therefore, there is a need for a light-guiding automobile taillight that prevents direct light from shining to meet the use requirements.
