In 2007, Philips Lumileds released the LUXEON K2 warm and neutral white LEDs that offer new lighting possibilities
Warm-white and
neutral-white LUXEON K2 emitters and a LUXEON K2 Star part can be specified with
any standard white emitter.
The new white colors have typical correlated color temperatures
(CCT) of 3000K and 4100K and a color rendering index (CRI) of 80 and 75 respectively. The
CCT range for LUXEON K2 now extends from 2670K to 10,000K and a new finer color bin
structure allows for better overall selection.
Unlike most power
LEDs that are limited to 700mA, LUXEON K2 warm white and
neutral white LEDs can be run up to 1500mA and a junction
temperature of 150°C. The new warm-white and neutral white
can deliver more than 130lm and 140lm respectively. LUXEON K2
delivers more usable light at virtually any drive current and
junction temperature condition.
“With the increases in light output performance and efficacy, there is expanding demand for
power LEDs that deliver the quality of light required for general lighting applications,” said
Steve Landau, Director of Marketing Communications. “Designers of residential applications,
such as recessed can lights need uniformity, high color rendering and a warm white color
temperature at 3000K. In many retail and commercial applications, a cooler temperature of
4100K is desired. With the new binning and phosphor technologies in LUXEON K2, the needs of
lighting designers in both markets can be addressed.”
Lighting designers consider several critical “quality of light” factors when evaluating white LEDs:
color temperature (CCT), color rendering (CRI) and color uniformity are three of the most
important. The new LUXEON K2 parts address CCT and CRI and Philips Lumileds phosphor
expertise and technologies ensure the highest degree of color uniformity resulting in white LEDs
that are as much as 7 times more uniform that other white power LEDs.
LUXEON K2 Star, like the configuration already available in other LUXEON product families,
consists of a white LUXEON K2 emitter mounted onto a metal core pc board (MCPCB). This
configuration allows for rapid prototyping and production in a wide range of applications without
the need to create custom level 2 boards. LUXEON Star products have been an industry
standard for many years and been the configuration of choice for everything from architectural
and entertainment lighting to emergency and portable lighting. Complete product information
is available on the company’s website and in the LUXEON K2 datasheet also available online.
LUXEON K2 warm-white and neutral-white power LEDs are in-stock and available for immediate
delivery from Future Electronics. LUXEON K2 Star is stocked in limited quantities and
interested parties should contact Future Electronics with their specific needs.
