LED Dimming Methods for Improving Luminous Efficacy
碩士 === 國立臺灣科技大學 === 電機工程系 === 107 === PWM dimming method has been widely used for driving LEDs, and the average current through LEDs can be linearly controlled by adjusting the duty cycle of the dimming signal. However, most illuminance-current characteristic curve of LEDs is nonlinear. The smaller...
