Abstract
An energy-efficient, compact and cost-effective solution for driving a number of high-power LED groups for lighting applications includes using a single switching power supply together with LEDs connected in series and/or in parallel and pulse width-controlled switches in parallel across the individually controllable LED groups. If the switch of an LED group is ON, the LED group will not light up. If the switch is in the OFF position, the full current of the power supply will pass through the corresponding LED group.
