Panel points to developments in high-power LEDs
At a recent LEDs conference, leading manufacturers described progress in their high-power LED products.
,,The "big five" LED manufacturers, otherwise known as the usual suspects - Cree, Lumileds, Nichia, Osram Opto and Toyoda Gosei - were assembled for a panel session at the Strategies in Light conference to discuss advancements in, and new applications for, high-power LEDs.
Osram Opto's CEO, Ruediger Mueller, highlighted four key areas of growth: miniature projection systems, flat-panel display backlights, automotive headlights and general lighting. As well as reduced cost, these require improved color uniformity and increased surface brightness as key targets.
"LED technology will win where there is proven value over conventional technology; the battle is being fought application by application," said Jason Posselt, product marketing manager for Lumileds. "A focus on light sources, rather than discrete LEDs, will speed the adoption of solid-state lighting technology."
To address many applications, Lumileds has announced a complete redesign of its Luxeon high-power LED product, which when introduced this summer will provide 65 lumens at 350 mA.
In the longer term, Posselt highlighted cost targets of less than 1 cent per lumen, and coupled with hundreds or thousands of lumens per package. When pressed to say when he thought the 1 cent/lm barrier might be reached, he said, "Not this year, probably not next, but definitely within 5 years." Mueller agreed on the 3-5 years estimate, saying it was "inevitable" that production costs would fall.,,
