LED + SSL

Dresden University and German OLED company Novaled are claiming that they have achieved a source efficacy of 90 lumens/W. With this accomplished, researchers say they must now achieve their next breakthrough in increasing service life to make OLEDs competitive with other sources in general lighting applications.

As you probably know, long lifetime is considered to be one of the major advantages of solid-state lighting over other lighting technologies. It’s something [...]

WAC Lighting showcased two innovative OLED fixture prototypes at Lightfair last month, including an OLED mini chandelier and an OLED wall sconce. The OLED Wall Sconce features six color changeable three-inch OLEDs. The mini chandelier uses eight colorful, transparent, one-inch OLEDs, including a panel depicting the WAC Lighting logo. Each OLED draws only 0.18W; each [...]

Braemar Energy Ventures, a venture capital fund making early- to mid-stage investments in the energy technology sector, recently announced a $10 million investment in Fulham, an assembler and distributor of electronic ballasts and drivers for fluorescent, HID and LED lighting. Fulham joins Braemar’s energy efficient lighting portfolio comprised of Laser Light Engines, Nuventix and Luminus [...]

The Department of Energy hosts conferences and other events to exchange information and facilitate development of solid-state lighting (SSL). On April 21-22, DOE hosted an SSL Manufacturing Workshop in Fairfax, VA to help shape a DOE program aimed at reducing the cost of LED products to competitive levels while ensuring quality and consistent performance. The [...]

Check out how the Graffiti Research Lab uses light to create graffiti on buildings using LED throwies and digital light projection systems. See how a digital projection system is used to tag a building here (warning: foul language), entirely with light, and without leaving a lasting mark. More here at ABC News. See how LED [...]

The blazing fire is an amazing effect–I was able to see it firsthand at the Sylvania booth at Lightfair, which was showcasing this Traxon product. The video doesn’t quite do it justice, but check it out to get a feel for the special effect: Here's another interesting use of the same product: And another:
