Why do LED lighting fixtures use aluminum substrates?

As an intermediate and high-end metal substrate (MCPCB), the aluminum substrate is determined to be recognized by the market as an important factor: good heat conduction, good heat conduction and good heat conduction. Why LED lighting should use a good heat conductive metal material for the circuit board. LEDs generate a lot of heat when they work. This heat is fatal if it is not very conductive. It has a great influence on the light decay of LED lamp beads. Therefore, we must use aluminum substrate with thermal conductivity when choosing PCB circuit board. Metal substrate (MCPCB) has good heat dissipation and heat transfer capability, which is professionally referred to as heat conduction. This is the reason why LED lamps use aluminum substrates.

Aluminum substrate characteristics

● Surface Mount Technology (SMT);

● extremely efficient treatment of thermal diffusion in circuit design;

● Reduce product operating temperature, increase product power density and reliability, and extend product life;

● Reduce product size and reduce hardware and assembly costs;

● Replace the fragile ceramic substrate for better mechanical durability.

PCB aluminum substrate use:
