The COB light source means that the chip is directly packaged on the entire substrate, that is, N chips are inherited and integrated together on the substrate for packaging. It is mainly used to solve the problem of low-power chip manufacturing high-power LED lights, which can disperse the heat dissipation of the chip, improve the light efficiency, and improve the glare effect of LED lights. COB has high luminous flux density, less glare and soft light, and emits a uniform distribution of light.

COB light source is a high light efficiency integrated surface light source technology in the LED chip directly affixed to the high reflective mirror metal substrate, this technology eliminates the concept of support, no plating, no reflow, no patch process, so the process is reduced by nearly one-third, and the cost is saved by one-third.

COB light source can be simply understood as a high-power integrated surface light source, and the light area and size of the light source can be designed according to the shape structure of the product.
