What is K-COB?

K-COB is a unique LED packaging pattern --by using exclusive laser caramic to replace traditional silicone and phosphor, we developed this brand new generation of LED light source.

  • No phosphor: using laser ceramic instead of silicone&phosphor;

  • Dual channel heat sink: thermal conduct from both ceramic&PCB

  • Smaller Chip size: 15%smaller than regular COB,provide better light distribution;

  • Longer Lumen intensitythe lumen decay less than 10% in 50,000 hrs;

  • CCT option: 2000~6500K, (the lowest CCT exact same as HPS lamp);

  • LM80: One and only supplier who applied LM80 test for 600w single chip in Bacl.

  • Core Material-Laser Ceramic

    Core material: laser ceramic developed by CAS, high temp resistance and conductivity, perfect replaceement for traditional phosphor in LED chip;


  • Core Package-Low thermal resistance packaging structure

    Core packaging: Laser ceramic cover + solid packaging structure + PCB board;



  • Core Parts-All-in-one madule

    Core parts: Developing with CAS TC, we provide all-in-one lighting module.
