LED + SSL

LEDs are used for a wide variety of indicator and illuminator applications, from furniture to clothing, and now even signage at protest marches. LUX has the story below starting at the 2:17 mark.

In this contribution to Electropages.com, Mouser Electronics’ Mark Patrick sums up developments in LED lighting technology this year. He covers increases in device efficacy, anticipation for Bluetooth Mesh, TM-30 and more. Check it out here.

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 A few months ago, we devoted a Posting to the GATEWAY field study OLED Lighting in the Offices of Aurora Lighting Design, Inc., which — despite several challenges that were encountered — [...]

Below is my lighting column published in the January issue of tED Magazine. Reprinted with permission. The majority of LED lamps and luminaires feature an electronic driver that performs the same basic function as a fluorescent ballast. The driver converts AC supply voltage to DC and drives current to the LED source. In the traditional [...]

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 DOE’s LED Lighting Facts® program has come out with a handy new tool for lighting designers and specifiers, which can make their job a whole lot easier. The LED Lighting Facts Specification [...]

My contributions to the December issue of ELECTRICAL CONTRACTOR included a prominent feature on flicker in light sources, notably LED. What’s being done about it at the industry level and what specifiers can do about it to ensure good performance. The article begins: Flicker in light sources is an old problem made new again in [...]

The U.S. Department of Energy recently posted the presentations from the 2016 DOE SSL Technology Development Workshop, held November 16–17 in Denver. Tunable-white lighting, connected lighting, TLEDs, OLEDs, controls and more. Check it out here.

The U.S. Department of Energy’s CALiPER program has released a new Snapshot report on LED downlights. Among the key findings of the new Snapshot, which is based on DOE’s LED Lighting Facts database: • Across all products listed with LED Lighting Facts, average efficacy gains continue to track at about 10 lm/W per year. • [...]

ARCHITECTURAL LIGHTING recently published an article evaluating OLED general lighting technology and the obstacles facing broader adoption. Check it out here.
