Lumileds Phosphor Technology Expected to Simplify Binning

LEDs Magazine reports that Philips Lumileds has developed a new phosphor technology, Lumiramic, developed jointly by the company's Advanced Laboratories in San Jose and Philips Research in Europe. Luxeon products that use the new technology are expected in early 2008, and sampling programs will begin with customers in the lighting community in the fourth quarter of 2007.

Lumiramic phosphor technology enables targeted production of white LEDs to specific correlated color temperatures (CCT) on the black-body curve. This will result in high volume availability in the most desired color temperatures.

Lumileds says that by utilizing the new technology it may reduce the number of fine bins at a given CCT by 75% or more. This in turn should greatly simplify the efforts of the lighting community, which has asked the LED industry to reduce the variation in white LEDs and more effectively enable luminaire-to-luminaire consistency.

Lumiramic phosphor technology utilizes a ceramic phosphor plate in combination with the company's new Thin Film Flip Chip (TFFC) technology. The Lumiramic plates are being manufactured at Philips phosphor factory in Maarheeze, The Netherlands.
