Abstract: In order to improve the LED in terms of efficiency of illumination, a technique to control frequency and duty cycle are in the term key essentials. The objective of this research proposes to tests the lighting LED illumination which use for lighting applications with the pulse generator voltage source. Pulse voltage source change the duty cycle of the on signal voltage from 10% to 90% and change the frequency to be 100, 200 and 300 Hz respectively. When we control current lower than exceeding peak current of …
