It is a core accessory in a car headlight assembly. The light emitting source is the yellow LED patch lamp bead on it. It is a performance component that can switch between high beam and low beam. The lumen value of light reaches more than 1000LM. Colleagues need good heat dissipation performance. Fans and materials are commonly used to dissipate heat. The purpose of designing it is to design and beautify the performance components, I divided the design of automobile LED headlights into four parts, 1. Light source part; 2. Heat dissipation part; 3. Interface part; 4. Design elements.. The car light in everyone's consciousness is actually the car headlight assembly, which is only the light source accessory.
