NEMA Publishes White Paper on LSD 68 Remote Phosphor Devices Used in LED Drivers and Luminaires

The National Electrical Manufacturers Association (NEMA) published white paper NEMA LSD 68 Remote Phosphor Devices Used in LED Lamps, Engines and Luminaires.

®Presently, programs such as ENERGY STAR require testing of each complete remote phosphor system at system level. Although the most accurate approach to qualify remote phosphor systems for use in products may be to measure total system lumen and color maintenance at the system/product level, the amount of time and cost to test each product combination is prohibitive. Replacement of system-level testing by independent component-level testing is widely expected to be a fully adequate replacement, which will accelerate the introduction of new products and the adoption of solid-state lighting.

Remote Phosphor Devices Used in LED Lamps, Engines and Luminaires NEMA is the association of electrical equipment and medical imaging manufacturers, founded in 1926 and headquartered in Rosslyn, Virginia. Its 400-plus member companies manufacture a diverse set of products including power transmission and distribution equipment, lighting systems, factory automation and control systems, and medical diagnostic imaging systems. Total U.S. shipments for electroindustry products exceed $100 billion annually
