Description

Technical Field

[0002] Headlights, as an important part of safe driving, usually have three main parts: lampshade, light source and circuit controller. The lampshade is usually made of plastic or glass, and has a reflector inside to reflect the light to expand the lighting range. The bulb is the light-emitting part of the headlight, usually made of glass or ceramic, filled with inert gas and metal wire. When current passes through, the metal wire generates heat and emits light. The circuit controller includes the headlight switch, relay, fuse, etc., which is responsible for controlling the on and off of the bulb and protecting the circuit safety.

[0003] With the development of science and technology, the structure of car lights is also improving. Most of the car lights in the prior art adopt an emitting structure, that is, the light emitted by the light source is reflected and focused on the lens through a reflective lamp cup inside, with high light intensity and sufficient light. In the above structure, the light reflected by the lamp cup is always diffused, and the adapted lenses are adjusted in a targeted manner to improve the utilization rate of light energy. What's more, a dual light source design is used in a targeted manner, combined with a double-layer lens to achieve further focusing. However, the use of a dual light source structure will cause the overall heat of the light source to increase. When the heat dissipation performance remains unchanged, the light source is prone to overheating and damage, affecting the use of the car lights, which urgently needs to be improved.
