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
Supply of high-power LED 5W ~ 120w
