LUXEON Rebel PC Amber Hot/Cold Factor and Light Output Improve

Amber LEDs have been essential for automotive and construction/manufacturing lighting applications for some time and in the lighting market, they have been implemented in entertainment solutions. Now, there is particular interest from the makers of retrofit bulbs designed to replace traditional incandescent lamps and replicate the color change from white to reddish-yellow as the light is dimmed.

Unlike conventional bulbs, white LEDs do not change color as they are dimmed so the “color” of the white light is always the same. Adding an amber LED to the system allows a retrofit bulb’s light to change in a way that people already expect. However, amber LEDs typically have poor light output and color stability at the high temperatures found in retrofit bulbs. LUXEON Rebel PC Amber combines the same blue, thin film flip chip used in the company’s white LUXEON LEDs. By adding proprietary Lumiramic phosphor technology, Philips Lumileds manufactures a highly stable, reliable amber LED that performs in high application temperatures, high humidity, and high drive currents, and still delivers the light output, efficacy, and quality of light required.

“The InGaN based LUXEON Rebel PC Amber with Lumiramic phosphor simplifies system design,” said Frank Harder, VP of Product Marketing for Philips Lumileds. “It gives 4-5 times the light output of AlInGaP amber products so fewer pieces can be used, and it is much more reliable and cost effective from a lumens/watt and lumens/dollar perspective.”

Philips Lumileds continues to improve and expand its LUXEON Rebel LED portfolio so that lighting applications can more easily deliver the quality of light, efficiency, and reliability that customers are expecting from solid-state lighting solutions.
