High Current, High Brightness LEDs Simplify Power Supply Solutions By Steven Keeping, Electronic Products 2/14/2012 LEDs for mainstream lighting are much brighter and are capable of being driven at higher drive currents than the devices of just a few years ago. That means fewer chips are needed for lighting fixtures (luminaires) taking the pressure off designers who previously had to come up with complex power units (“drivers”) to supply long strings of dim LEDs.
