I know. Tell me about cob or led in the living room.

COB is an integrated LED light source, that is, multiple LED chips are packaged on a board. Generally, one LED lamp bead is packaged, and two are packaged independently. Two or more LED chips need to be displayed in different colors.

The special light of COB light source is lower than that of a single LED, and the main problem is heat concentration. The quality of COB and single light source lamps depends on the design process and materials, and the appearance is not easy to distinguish.

The same power is generally better than a larger radiator, but both the package and the chip affect the quality, so manufacturers should ensure the quality and try to choose the one with a long warranty period.
