Professional Custom Lamp Holder Accessories Manufacturer

COA (Chip On Aluminum) LED lighting technology in its printed on one side of the aluminum substrate a conductive line, while the insulating paint sprayed on the printed surface of a conductive wire and an insulating layer of paint sprayed on the surface provided with at least a light cup, the cup at the edge of each lamp corresponding set two copper electrodes, and then the LED chip fixed to the lamp holder, direct wire connection between the chips and the rest of the LED chip pin and two bronze respectively electrode is electrically connected, and finally between the LED chip and chip solder tails with fluorescent plastic and resin encapsulation. The aluminum substrate of the invention, both as light board and as a heat sink, the LED chip and lamp combination greatly simplify its structure, cooling effect, making simple, especially useful in high-power LED lights, and the line sealing, insulation well, increasing the light board security, stability and reliability.
