continues its major shift to LED technology. by Craig DiLouie
and architectural-grade segments. Energy efficiency, life, and cost drive the basic-grade market—with exam- ples such as lensed troffers and flat panels. Aesthetics, performance, and value-added features drive the specification- and architectural- grade markets. An example is lumi- naires offered as alternatives to trof- fers that feature advanced optics to reduce brightness and the number of luminaires required. This article presents the major trends driving LED product devel- opment and applications and how
IN THE SEPTEMBER 2016 UPDATE to its Energy Savings Forecast of Solid-State Lighting in General Illumination Applications report, the DOE estimated that 12% of the in- stalled base of commercial luminaires —or 136 million units—featured LED lamping in 2015. The DOE forecasted that under current industry condi- tions, these numbers would surge to 36%, or 436 million units, by 2020. Today, the majority of luminaires sold into new buildings and renovation projects feature LED lamping. As the technology matures, the LED luminaire market has stratified similarly to the conventional lighting market into basic-, specification-,
