COB LED soft light strip crystal characteristics and advantages

LED soft light belt refers to the LED assembly on the ribbon FPC(flexible circuit board), because its product shape like a soft belt named.The LED soft light belt is also called the flexible LED light belt, and the COB soft light belt refers to the soft light belt encapsulated by the COB flip process. COB refers to Chips on Board, which means that the Chips are directly encapsulated on the PCB Board.A COB strip is a strip that encapsulates the chip on a soft board.The chip mostly adopts flip chip, and the solid tin paste is linearly solid on the PCB board, and then a layer of encapsulation glue mixed with phosphor powder is directly dropped on the chip surface.The appearance is like a ramen stick on the PCB board, the light from the chip in the package colloid through refraction, reflection, and interaction with the phosphor, colloid evenly emits light of different colors, color temperature

COB lamp belt and lamp bead lamp belt difference:

(1) Due to the structural characteristics of the COB lamp belt, the luminous surface is a linear colloid;

And ordinary lamp bead type lamp belt, its structure is a luminous lamp bead, pasted on the PCB board.

Therefore, the light emitted by the COB lamp belt is much more uniform, linear, without light spot;

(2) The heat of COB chip can be quickly transferred to PCB because the crystal is directly fixed on PCB board.

Therefore, the chip heat dissipation rate of THE COB lamp strip is faster than that of the lamp bead lamp, and the light decline of the COB lamp strip is smaller and the life is longer;

(3) The luminous Angle of COB lamp strip can reach 180°.
