Background technique

LED is a low-field electronic semiconductor light-emitting device, which can directly convert electrical energy into light energy. With the advantages of energy saving and environmental protection, high brightness, long service life, strong shock resistance, and less maintenance, it has been widely used in lighting, backlight, landscape decoration, traffic lights and other fields.

In the field of automotive lighting fixtures, LED light sources are gradually replacing the original incandescent bulbs. The traditional light guide strip generally adopts the method of setting a light source at one end. The light generated by the light source obliquely enters the light guide strip, and the light is transmitted inside the light guide strip by reflection. During the transmission process, part of the light is reflected At the same time, refraction occurs, and the refracted light exits the light guide strip to form illumination light, and this kind of refracted light has less diffuse reflection due to the smooth surface of the light guide strip, so it can only be seen in the direction that meets the refraction angle.
