Know more detail about COB and CSP strip

COB strip light has been in the market since 2019 and is a very hot new product,also the CSP strips.But do you know what are the characteristics of each?Some people also called CSP strip as  COB light strip, because their appearance is very similarbut they are actually different light strips,here we will explain the difference clearly.

COB strip light Structure:

1> Flip chip. The color change is achieved by applying phosphor.

2> The chip supplied by the supplier does not have fluorescent powder, so the factory needs to use fluorescent powder glue to achieve the desired color during production. Chip cost compared to CSP will be lower. White products only need to point a color of phosphor glue, high production efficiency, the corresponding cost is low. This product is not suitable for RGB products, if you do RGB, you need every color point phosphors glue, and then together point phosphors glue, very low efficiency, very high production cost, so COB is suitable for white light, RGB, RGBW low efficiency, high cost, light color is not uniform.

CSP strip light Structure:

1> Flip chip, the supplier has already ordered the fluorescent glue chip, the factory does not need to point phosphor glue.
Because the CSP chip supplier will carry out color packaging processing, the price of CSP is more expensive than that of COB chip. If white light is made, the cost of CSP is higher than that of COB at present. If it is to do RGB, RGBW, because the received material is already a good glue chip, the manufacturer only needs to directly glue welding chip, no more color processing, so the price of the finished CSP RGB, RGBW has a comparative advantage.

COB strip is 120 degree illuminate while CSP strip is 5-sided luminescence,both of them has excellent light spot and Light efficiency.we have version for indoor use and outdoor use,Ultra-narrow series also available if you need.Contact us and we can share more information about LED strip lights.
