What is 4mm COB led strip?


COB stands for Chips on Board, which means that the chip is directly packaged on the PCB (Also called continuous light strip). The COB light strip is a light strip that encapsulates the chip on a flexible board. Chips mostly use 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.


Where can I buy bulk supper narrow COB light strips?


If you import COB bar from China first, you can directly search "China Wholesale COB light bar" on Google, there will be thousands of search results, you can find a reliable supplier from it.

What are the differences between COB light strips and ordinary LED light strips?


①Due to the structural characteristics of the COB light strip, the light-emitting surface is a linear colloid; while the ordinary lamp bead type light strip, its structure is a luminous lamp bead, which is attached to the PCB board. Therefore, the light emitted by the COB lamp belt should be much more uniform, linear, and no spot;


② Since the COB chip is directly bonded to 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 light strip is faster than that of the bead type lamp, and the light decay of the COB light strip is smaller and the life span is longer;


③The luminous angle of the light-emitting surface of the COB light bar can reach 180°.
