LED + SSL

As in previous years, the U.S. Department of Energy’s Solid-State Lighting Program offered free educational sessions at its booth at LIGHTFAIR International. These booth presentations are now posted are now posted on the DOE SSL website. Click here to download them.

In December 2015, LD+A published a column, “The LED Driver Dilemma,” by Jerry Plank. That month’s Safety Column discusses how LED driver substitution continues to be hampered by a lack of standards. Click here to read an excerpt.

I recently had the pleasure of interviewing Scott Wegner and Kevin Broughton, principal optical engineers for Eaton. The topic: LED optics. I’m happy to share their responses with you here. The interview informed an article I wrote for the June 2016 issue of tED. DiLouie: What is the purpose of an optical system, as applied [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy The topic of droop comes up quite a bit when discussing LED lighting R&D. But exactly what is droop, and why do we care about it? Simply put, droop is a phenomenon [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy All conventional light sources modulate luminous flux and intensity — i.e., they flicker — to some degree. Flicker is garnering increasing attention from lighting designers and specifiers, the standards and specification community, [...]

My contribution to the March issue of The Electrical Distributor tackled a big subject–trends in LED outdoor luminaire design. Reprinted with permission. Offering higher efficacy, longer life, greater optical control, good quality of light and greater control flexibility, LED lighting stands poised for major penetration in the outdoor stationary lighting market. These luminaires may be [...]

LEDucation, coming March 29-30 to the NY Hilton Midtown in New York City, has announced its speaker lineup, which you can see in detail here. This education event will host 30 sessions and three panel discussions for both beginner and intermediate levels. Register here.

The LED revolution is really the solid-state lighting revolution, with more than one choice on the menu. The emergence of OLED technology will create new possibilities for lighting design. If successful, OLEDs will become part of the transformation of the built environment and the lighting industry. Click here to read my December 2015 column for [...]

Below is a short article I contributed to the January 2016 issue of tED Magazine, published by the National Association of Electrical Distributors (NAED). Reprinted with permission. The U.S. Department of Energy’s CALiPER program has released Report 23: Photometric Testing of White-Tunable LED Luminaires, the first in a planned series on this nascent product category. [...]
