1) COB RGB multiple-color
2) Turly dotless & continuous, ideal for linear and indirect lighting
3) 180° beam angle, wider lighting distribution than 120° SMD LED beads
4) Super perfect color unifomity, soft and cozy lighting without glares
5) Super bendable up to a small angle
Chip on board (COB) or Flip Chip on board (FCOB) is a manufacturing method in which the chip is wired and directly bonded to the printed circuit board. This allows a dense arrangement of chips close to each other. If you would like to know how to make the flip-chip onboard/COB LED strip lighting, please Click Here.
Compared with SMD technology, which can only package 1-3 chips on the nano sapphire and gallium crystal substrate, COB can put more chips on the circuit board in the same space to provide more lumens and higher uniformity. LED light strips have been using SMD technology beads until 2019, such as SMD3528, SMD2835, SMD5050, SMD2110, SMD2216, SMD3014, SMD3838, SMD4040,SMD5630, SMD5730, etc. These light beads fix the lamp beads on the FPCB through SMT technology. However, even with the smallest lamp beads and the densest design, it can’t solve the problem of lighting spots.
Now the COB/FCOB led strip lights solve that problem and output the truly dotless and continuous linear lighting
