What is COB?
COB is Chips on Board, which means that the chip is directly packaged on the PCB, the COB flexible strip is a lighting strip that encapsulates the chip on a flexible board.
Chips are mostly flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped ono the surface of the chip. The appearance resembles a piece of ramen glued to the PCB Board, the lighting emitted by the chip is refracted/reflected, and interacted with the phosphor inside the encapsulating gel, the gel uniformly emits light of different colors and color temperatures.
The difference between COB led strip and normal led strip
1: The structural characteristics of the COB, the light-emitting surface is a linear colloid, while the ordinary led strip which is structure is a luminous led and led, so the lighting emitted of COB flex strip should be much more uniform, no dark spot.
2: The led strip used in the aluminum profile are conventional led strip before, it has a little dark area every unit length, the COB led strip with higher led chips is a good choice to solve the lighting dark area.
3: The COB led strip can be folded in 180 degrees without damaging led strip, it is very flexible to use.
