New LED Driver Could Provide More Efficient & Brighter LEDs


A new high-performance LED driver has been developed by researchers from the Department of Electronic and Information Engineering. The driver will provide brighter, more energy-efficient LED light bulbs.


How does it do it? The driver provides power to the light bulbs via a “multi-level PWM” or pulse-width modulation. This innovative approach has showed substantial improvements in light quality and energy efficiency.


The press release explains, “By traditional method of pulse width modulation, LEDs are fed pulsed current instead of steady DC. The drive current is turned ON and OFF at a rate faster than being perceptible by human eyes. Power LEDS in pulses make their light output easily controllable.”
