Abstract

             The heat generated by high power LEDs has a significant impact on the life time and brightness, so the thermal management is important. This research presents and compares the cooling capacity of high power LEDs that power is 60 Watt using a water cooling device with thermoelectric cooler. The average inlet water temperature was 20oC, water flow rate were varied to 1.96, 4.01, 5.78 and 8.29 L/min and the current was supplied to the thermoelectric cooler were varied to 2, 4 and 6 A. From the experimental result shown that when the water flow rate increases, the temperature of LEDs decreases, but at one point, the temperature of LEDs will increase. When current was supplied to thermoelectric cooler increases, the temperature of LEDs is decreases, but when the supplied current is too low, the temperature of LEDs is higher. The optimal heat dissipation is when the supplied current is 6 A and water flow rate is 5.78 L/min, the average temperature of LEDs is 4.3oC
