  • Luxeon A LED

SAN JOSE, Calif., April 29, 2011 — The Luxeon A introduced by Philips Lumileds is the latest illumination-grade LED that reduces the engineering effort required for new solutions and delivers freedom from binning. Sharing the Luxeon Rebel ES platform and footprint, it incorporates a 2-sq-mm thin-film flip chip and Lumiramic phosphor technology to deliver high-quality light at 2700 K and 3000 K, with high efficacy and light output.

The LED is hot-tested and specified at a junction temperature of 85 °C, which represents real-world operating conditions. Proprietary chip and phosphor technology allows color targeting that ensures that the emitter falls within a single three-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 concerns about the suitability of LED technology for illumination applications.

The company says that it delivers illumination-grade LEDs that improve the state of the art in lighting and that the LED performance 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.

Operating at 700 mA, the LED offers a minimum color rendering index of 80, typical hot flux of >175 lm and typical hot efficacy of 100 lm/W.

flip chip
An optical switch that controls conduction paths into and out of a junction in fiber optic and integrated optical circuits.
thin film
A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
