Lumileds adds hot-tested LUXEON A illumination-grade LED with Freedom From Binning

Philips Lumileds of San Jose, CA, USA says that its latest illumination-grade LED reduces the engineering effort required for new solutions and delivers Freedom From Binning. The LUXEON A shares the LUXEON Rebel ES platform and footprint and incorporates a 2mm2 thin-film flip-chip and Lumiramic phosphor technology to deliver what is claimed to be the highest-quality light at correlated color temperatures (CCTs) of 2700K and 3000K with high efficacy (100 lumens/Watt at 350mA) and light output (175lm).

Lumileds says that its unique chip and phosphor technology allows color targeting that ensures all LUXEON A emitters fall within a single 3-step MacAdam ellipse on the black-body curve. The quality, uniformity and consistency of the light from LED to LED relieves luminaire manufacturers and lighting designers of many of their long-held concerns about the suitability of LED technology for illumination applications, adds the firm.

Lumileds says that Freedom From Binning gives confidence in the quality of light, and Lumileds’ hot testing pays dividends for engineers designing LED solutions. The LED industry has long tested and specified products at an LED chip junction temperature of 25°C. It is well known that, in applications like down-lights and retrofit lamps, LED junction temperatures are more likely to be near 85°C, so luminaire manufacturers have had to make many complex calculations to determine actual light output, efficacy and color point of their products. In contrast, all LUXEON A LEDs are hot-tested and specified at a junction temperature of 85°C that represents real-world operating conditions. Providing the actual operating condition information means that there’s no ambiguity, performance hyperbole or wasted engineering effort, simplifying the process, says Lumileds.

“Our LUXEON LEDs are delivering performance that does not require sacrifices in the quality of light for homes, restaurants, shops, and other applications in pursuit of energy efficiency and reduced operating costs,” says Steve Barlow, senior VP sales & marketing.

LUXEON A is available for sampling and design-in activities now, and will enter high-volume production in early May.
