Copper Substrate For Automobile Lights Product Introduction
1.Product Overview
Copper substrate for automotive lighting is a printed circuit board designed for automotive lighting systems, using copper as the main thermal and electrical conductive material. Since automotive lamps generate a lot of heat when working, the superior heat dissipation and electrical properties of copper substrates make it an important part of modern automotive lighting solutions.
2.Main Features
Excellent heat dissipation performance:
Copper has high thermal conductivity (about 400 W/m·K), which can quickly dissipate the heat generated by LED lamps, prevent overheating, and ensure that the lamps work at the optimal temperature, thereby extending the service life.
High current carrying capacity:
The copper substrate has excellent electrical conductivity and can carry higher currents, which is suitable for high-power automotive lighting equipment such as headlights, taillights and daytime running lights.
High temperature and corrosion resistance:
Automotive lamps are often exposed to high temperatures and harsh environments. Copper substrates have good high temperature resistance and corrosion resistance and can work stably under various environmental conditions.
Lightweight design:
Compared with traditional aluminum substrates, copper substrates are lighter, which helps to reduce the overall weight of the car and improve fuel efficiency.
Good electrical performance:
Copper substrates can effectively reduce resistance, improve current transmission efficiency, and ensure the brightness and stability of lamps.
