Chip containing the radiator cover (COHS)

1.COHS is "Chip On Heat Sink", on behalf of LED chip set directly on the radiator cover

2. No other material has a thermal resistance between the LED chip and heat sink

3. advantages: 1) the lowest thermal resistance
2) The cost of the package structure
3) easy to control the T-junction
4) Flexible design capability

Quality control
COHS simple package structure can be measured to the actual T-junction
