COB LED Strip Lights / Yiford

what is COB LED strip Lights?

COB (chip on board) LED strips are different from traditional led SMD LED strips. COB strip lights are strips that encapsulate the chip on a flexible circuit 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 on the surface of the chip light source. The appearance resembles a strip of ramen glued to the PCB board.
The light emitted by the chip is refracted, reflected, and interacted with the phosphor in the packaging colloid. phosphor coating reflective surface made cob led strip lights single color or rgb dream colorful, The colloid evenly emits light of different colors and color temperatures.

What is the difference between COB light strips and traditional light strips?

COB LED Strips VS SMD LED Strips

1. Due to the structural characteristics of the COB (chip on board) light strip, the light emitting surface is a linear colloid; while the ordinary SMD (smd surface mount) type light strip, its structure is a luminous lamp bead, which is attached to the PCB board. Therefore, the light emitted by the high quality COB light strip should be much more uniform, linear, and there is no light spot; 2. Since the COB chip is directly solidified on the PCB board, the heat of the chip can be quickly transferred to the PCB board. Therefore, the heat dissipation speed of the chip of the COB led light is faster than that of the SMD type strips, and the light decay of the COB light strip is smaller and the life span is longer; compared to cob leds, new led technology led strip light brings better lighting solution. heat sink not necessary, cost effective. energy efficiency. 3. The luminous angle of the light emitting surface of the COB led light source can reach 180°.
