This paper shows the new structure of power supply for LED light with power adjust function with high efficiency. The commercially available LED power supplies are increasing its power efficiency. Currently up to 93% are available for power supply those are less than 100Watt. But, those powers show high efficiency for limited range of load condition. If the loads request the different voltages or currents than the power supply suggested one, its efficiency are very low than the 'good efficiency'. It means it has very low efficiency for the dimming condition. So this paper mentioned the new structure of high efficiency power supply that can keep the high efficiency over the dimming range 10 to 100% of rate tower.
