What is the difference between led and cob lights?

The biggest difference between led lights and cob lights is their light source.

The led light is a surface mount light-emitting diode with a large light-emitting angle, up to 120-160 degrees. Compared with the early plug-in package, it has the advantages of high efficiency, good precision, low false welding rate, light weight and small size.

Cob light means that the chip is directly bonded and packaged on the entire substrate, that is, N chips are integrated together on the inner substrate for packaging. It is mainly used to solve the problem of manufacturing high-power LED lamps with low-power chips. It can disperse the heat dissipation of the chips, improve the light efficiency, and improve the glare effect of LED lamps. COB has high luminous flux density, less glare and soft light, and emits a uniformly distributed glossy surface.
