Full article:The latest offering on the solid-state lighting (SSL) product documentation front is the National Electrical Manufacturers Association’s (NEMA) white paper: LSD 49-2010 Solid State Lighting for Incandescent Replacement-Best Practices for Dimming. With its release, LSD 49 joins NEMA’s compendium of white paper reports on a variety of lighting topics.
Drafted by NEMA’s Solid-State Lighting Section, chaired by Robert Hick of Leviton Manufacturing, the paper outlines recommended practices for the dimming and design of screw-based incandescent replacement SSL products. The goal of the document is to promote coordination between control, power supply, and LED modules between manufacturers in order to achieve industry-wide synchronicity for all LED-based luminaire products that enter the market.
The NEMA SSL Section also has started work on a related NEMA standard. Additionally, the U.S. Department of Energy (DOE) is participating in the working group that NEMA set up to devote to this subject, as the DOE has shared concerns related to the performance of SSL products in the marketplace. LSD 49 can be downloaded for free at nema.org/stds/lsd49.cfm
