July 16, 2010... Philips Lumileds reports that the Amber version of its Luxeon Rebel phosphor converter (PC) LED now has improved performance. Specifically the amber LED has a 12 percent increased hot/cold factor at 80 degrees C. The hot/cold factor indicates how much light is delivered at operating conditions as opposed to test conditions. Additionally, Philips Lumileds contends that the LED's lumen output and lumens per watt (efficacy) performance exceed that of all other amber power LEDs.

The company points out that amber LEDs have been essential for some time in automotive, construction/manufacturing, and as lighting in the entertainment industry. Now, according to the company, makers of LED-based retrofit bulbs have particular interest in using amber LEDs to help replicate the color change from white to reddish-yellow as the light is dimmed. Despite being used in many applications, conventional amber LEDs have not stood up well to the high temperatures required, and are not bright enough and the color isn't stable enough for many general lighting applications.

The Luxeon Rebel PC Amber LED is actually a blue, thin film flip chip Luxeon Rebel LED used in the company’s white Luxeon LEDs, with the company's proprietary Lumiramic phosphor technology.
