lampshade of led high bay light is made of aluminum substrate .Aluminum base plate is a metal having good heat dissipation CCL, generally consists of three single-panel structure, namely the circuit layer (foil), the insulating layer and the metal substrate. Also used for high-end dual-panel design, the structure of the circuit layer, an insulating layer, aluminum, an insulating layer, a circuit layer. Very few applications of plywood, plain plywood can be made with the insulating layer, aluminum bonding together.
LED aluminum plate is the PCB, the PCB also mean, just the circuit board material is aluminum, we used the average fiberglass circuit board material, but because the LED heat larger, so the board is generally used for LED lamps aluminum plate, can heat quickly, electrical circuit boards or other equipment used in class or fiberglass board. so chip of led high bay light can produce heat as soon as possible to the heat sink .
Works principle
Power device surface mounted on the circuit layer, the heat generated during operation of the device through the insulating layer to a conductive metal substrate quickly, and then the metal substrate to transfer heat out of the cooling device in order to achieve
Superiority
And the ratio of the conventional FR-4, the thermal resistance of the aluminum substrate can be minimized, so that the aluminum plate having an excellent thermal conductivity; compared with the thick film ceramic circuit which is extremely excellent in mechanical properties.
In addition, aluminum plate as well as the unique advantages:
1, with RoHs requirements;
2, more adapted to the SMT process;
3, the circuit design of the thermal diffusion in a very effective treatment, thereby reducing the module operating temperature and prolong life, increase power density and reliability;
4, reduce the heat sink and other hardware (including thermal interface material) assembly, smaller footprint, lower hardware and assembly costs;
5, the power circuit and control circuit optimization portfolio;
6, replace the fragile ceramic substrates, better mechanical durability.
Led high bay light use aluminum substrate as lampshade , can get better benefit. People don’t havt to worry about the problem of heat dissipation .
