San Jose, CA — Philips Lumileds today introduced a new phosphor technology, Lumiramic, developed
jointly by the company’s Advanced Laboratories in San Jose and Philips Research in Europe. Lumiramic
phosphor technology enables targeted production of white LEDs to specific correlated color temperatures
(CCT) on the black-body curve resulting in high volume availability in the most desired color temperatures.
Utilizing Lumiramic phosphor technology, Philips Lumileds may reduce the number of fine bins at a given
CCT by 75% or more. This will 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. Eliminating complex binning schemes, ensuring consistent high-volume supplies of white LEDs
on the black-body curve, and making it easier than previously imagined to meet future Energy Star guidelines
are just some of the efforts Philips Lumileds is undertaking to facilitate and speed the development of never
before possible lighting solutions.
Lumiramic phosphor technology
utilizes a ceramic phosphor plate and
the company’s new Thin Film Flip
Chip (TFFC) technology. TFFC
technology, recently introduced in Luxeon Rebel, is the only thin film process that removes the anode and
cathode from the light output path and provides an unobstructed plane to which the Lumiramic plate can be
applied. This optical alignment is not possible with other thin film technologies. The technology is already
being incorporated into the company’s LED automotive headlamp products, so that the auto industry’s
stringent color consistency requirements are met easily and through a completely scalable manufacturing
“Philips Lumileds is vertically integrated meaning we develop, manufacture and use our own chip, phosphor
and packaging technologies. Thus our scientists and engineering teams have the unique ability to direct our
efforts with the intent that advances in one area are not just supported by other technologies, they are designed
to work in conjunction with advances in each of the other technology areas,” said Frank Steranka, Executive
Vice President of Research & Development. “TFFC and Lumiramic are a perfect example of two technology
advances that independently provide great value to the market but together, enable an entirely new level of
lighting performance. Lumiramic and TFFC were two of the key technologies used to achieve the 115 lm/W
performance announced earlier this year and we continue our work on the remaining technologies that will
take our performance to these levels and beyond.”
The Lumiramic plates are being manufactured at Philips phosphor factory in Maarheeze, The Netherlands.
Philips Lumileds will introduce Luxeon products with Lumiramic phosphor technology in early 2008 and will
begin sampling programs with customers in the lighting community in the fourth quarter of 2007.
Philips Lumileds pioneered power LED technology and is the world’s leading provider of power LEDs for
lighting applications. The company’s records for light output, efficacy and thermal management are direct
results of the ongoing commitment to advancing solid-state lighting technology and enabling lighting
solutions that are more environmentally friendly, help reduce CO2 emissions, and reduce the need for power
plant expansion. Philips Lumileds’ Luxeon LEDs are enabling never before possible applications in the
automotive, digital imaging, display, projection, and general lighting markets. More information about the
