COB means Chips on Board, which means that the chips are directly encapsulated on the flexible PCB board, and the COB led strip is a strip of chips encapsulated on a flexible board. The chips are mostly flip-chips, which are linearly fixed on the PCB board, and then a layer of encapsulation glue mixed with phosphor is directly dropped on the surface of the chip. The light emitted from the chip is refracted, reflected, and interacts with the phosphor, and the glue emits different colors and color temperatures of light evenly.
The Advantages of COB led strip:
- Due to the structural characteristics of COB led strips, the light-emitting surface is a linear gel, whereas, with ordinary SMD led strips, the structure is one light-emitting bead at a time, attached to the PCB board. So the light emitted by COB strips is much more uniform, linear, and without light spots.
- The COB chip is directly fixed on the PCB board, the heat of the chip can be quickly transferred to the PCB board. Therefore, the heat dissipation rate of the COB led strip is faster than that of the SMD led strip, and subsequently, the light decay of the COB led strip is smaller, and the life span is longer.
- COB led strips with a luminous surface up to 180°.
