Programmable drivers add flexibility to LED lighting LED drivers have developed over the years from constant voltage topologies to the much more energy efficient constant current setup. Constant current drivers deliver the required current directly to an LED without an additional current regulator and are widely available in a variety of current output levels. Recently, as LED luminaires have continued to develop in complexity and range and the number of different fixtures on the market has increased, lighting designers have begun to demand flexibility from their driver hardware that the basic constant current topology can’t provide. In the latest Engineers' Insight, Don Schriek explores some of the latest programmable LED driver solutions for indoor and outdoor lighting.
