This circuit approach provides a simple way to control multiple LEDs from a processor. Doing so enables the solutions to LED aging and variability to be implemented in a more cost-effective manner.

A small round LED floodlight. Before installing them on the tractor, he tested them on the workbench. Frank was impressed with how much light both fixtures provided, exceeding the brightness of his ...

Multiple dimming techniques have been developed using both linear and digital methods. In both, the brightness is determined by the average forward current in the LEDs.
