Lumileds boosts LUXEON CoB LED arrays to lumen range of 1000-7000lm and efficacy of 130lm/W

Philips Lumileds of San Jose, CA, USA says that, just months after being launched on the market, its LUXEON CoB (chip-on-board) LED arrays now provide 10% greater performance.

The result is luminous efficacy of up to 130lm/W and what is claimed to be the highest combination of lumens, package density and efficacy in the industry. For example, in warm white, the 9mm array delivers 2200lm at 100lm/W and the cool white array delivers 2500lm at 105lm/W.

Utilizing a small light-emitting surface (LES) of 9, 13 or 15mm, designers can use less expensive optical solutions, resulting in ultra-compact luminaires that deliver outstanding center-beam candle power, it is claimed.

In addition to optical advantages, the metal-core printed circuit board of the LUXEON CoB substrate provides four times better heat transfer than competitive solutions, it is reckoned, enabling up to 40% smaller heat-sinks or improved reliability of the lighting system when a larger heat sink is used.

“With the recent improvements in performance, LUXEON COB is an even better option for a number of general lighting solutions, including outdoor, industrial, retrofit lamps and, of course, spotlights and downlights,” says product line director Eric Senders. “Our 90-CRI versions have a typical CRI [color rendering index] of 97, which makes them perfect for high quality of light applications,” he adds. “Lumen packages are available with CCTs [correlated color temperatures] of 2700-5700K and CRIs of 70, 80 or 90.”
