Copper Substrate

Aluminum substratehave a good thermal conductivity. they are widely used in telecommunications, electricity, electronics, medical equipment, mechanical equipment, lighting and other fields. Apply filed tunnel lights,LED street lamp,wall washer lamp,led underground lamp,ball bulb lights,dimming lamp,led lamp cup,spot lamp, projection lampand so on.
