The ninth annual LEDs and first-ever LEDs Measurement and Standards conferences
| Tweet |
If you’ve recently walked through lighting or LED-related, conference exhibit aisles, you may have been momentarily blinded by the seemingly, ever-brighter LEDs found in exhibitors’ booths, because LEDs are becoming brighter and more efficient. Even better, you’re seeing improved color quality. Expect this trend to continue, because much is going on behind the scenes.
I’ve just returned from San Diego, where I attended the Ninth Annual LEDs 2008 and first-ever LEDs Measurement and Standards conferences. This event provided 440 attendees with firsthand insights for LEDs future. A 61-booth tradeshow accompanied the conference. The event was organized by IntertechPira (www.intertechusa.com) and directed by LED Consulting’s Kathyrn Conway, along with representatives from Cree, Osram Opto Semiconductors and Philips Lumileds.
The first day comprised five, introductory seminars that overviewed the solid-state lighting (SSL) industry, driver technology, thermal and optical designs, and luminaire-construction strategies.
The following days’ topics covered emerging LED markets (most notable was backlighting systems for LCD-based TV screens, monitors, and notebook computers); street lighting; residential and decorative lighting; next-generation lighting solutions for signage applications; and the high-brightness, white LEDs for automotive headlights and general illumination -- the most demanding technology. Presenters represented large, medium and small LED and lighting manufacturers, driver producers and luminaire testers, as well as such supporting organizations as the U.S. Dept. of Energy (DOE) and the U.S. Environmental Protection Agency (EPA).
LEDs 2008 also included a panel/audience discussion on improvement of LED efficacy, color rendering and quality. We also debated LED lifetime claims.
By agreement, we limited LED standards and photometric-measurement topics because a separate, two-day, measurements and standards conference immediately followed LEDs 2008, in the same venue.
At the exhibit, the DOE spoke of its Energy Star SSL program and reported on the Illuminating Engineering Society’s (IES) adoption of the LM-80-2008 standard, that is, the “Approved Method for Measuring Lumen Depreciation of LED Light Sources.” The DOE also advised LED and lighting manufacturers how to qualify products for its Energy Star criteria. It now provides a preliminary document, “Manufacturer’s Guide for Qualifying Solid-State Lighting Luminaires,” which outlines performance benchmarks. The document lists DOE’s certified facilities that conduct Energy Star qualification testing; it also details Energy Star approval procedures.
Interestingly, the EPA also has an Energy Star program that includes a residential, LED-based, light-fixture qualification.
