Standard Released for Lighting LED-driver Interface

The Module-Driver Interface Special Interest Group (MD-SIG) released its new specification for a universal electrical interface between LED lighting modules and power supplies, according to an Electronic Weekly report.

The standard supported by Osram, Panasonic, Philips and Tridonic is called LEDset1 edition 1.0, and has a three wire interface that includes power, ‘lset’ and return for both. It allows for separate returns for main and set currents to avoid setting errors due to return voltage drops. The ‘lset’ has nothing to do with dimming.

Further details about the standard can be viewed here.
