Thermal Design for 5 Watt Power LED

With the consideration of the thermal management and heat sink requirements,a cooling device is designed and the thermal resistance of this device is calculated with a single 5 W power LED.The thermal design of a single 5 W power LED is reasonable,effective and the result has been simulated.This design also instruct other power LEDs' thermal design.Provided is a reliable and effective method for the design of power LED illumination lamps and lanterns.
