Philips Lumileds announced the release of two new LUXEON Rebel LEDs with correlated color temperatures (CCTs) of 2700K and 3000K that expand the company’s portfolio for indoor illumination applications in hotels, shops, restaurants, and homes.

The new emitters use Philips' latest thin film flip chip (TFFC) and proprietary Lumiramic phosphor technologies. At the high operating temperatures found in applications like recessed lamps, the new emitters set efficacy benchmarks.

Philips also contends that the implementation its Lumiramic phosphor technology reduces the white binning space, advancing the company’s drive to free customers from white color binning, provides superior color uniformity and raises the standard for quality of light.

New LUXEON Rebel Emitter Highlights

• Typical efficacy of 80 lumens per watt and up to 95 lumens per watt at 350 mA and 3000K CCT
• Consistent efficacy across the typical operating temperature range
• Specified CRI—typical 85
• Industry’s smallest and most consistent, white binning space
• Only power LED with specified color over angle performance
• Superior light output performance at application conditions

Philips also claims that the new Rebel emitters will be stable from an efficacy perspective over a wide temperature range. The company points out that most LED specifications are based on a 25ºC junction temperature, whereas many downlights and retrofit lamps may operate at temperature in the 80ºC~100ºC range.

According to Philips, the new emitter maintain more than 90% of rated light output and more than 95% of specified efficacy at a junction temperature of 85ºC.

The new 2700K and 3000K CCT LUXEON Rebel emitters are available now in evaluation and prototyping quantities directly from Future Lighting Solutions’ regional marketing centers. High volume production quantities will be available in August 2010.
