SAN JOSE, CA (January 30, 2006) --- Lumileds Lighting today announced release of its
LUXEON® K2 LEDs that set industry benchmarks in a variety of areas including light
output, temperature tolerance and drive current. LUXEON® K2 Emitters enable the
development of solid-state lighting applications with
more useable light, reduced thermal management
engineering, lower cost, and simpler manufacturing.
“LUXEON® K2 shatters every performance record in the
power LED industry by a wide margin, and that has
far-reaching implications for luminaire manufacturers
and other lighting solution providers,” said David
Eastley, Lumileds product manager for the LUXEON® K2 line. “With LUXEON® K2 we start
a new chapter for solid-state lighting by simultaneously increasing the brightness
threshold and simplifying the engineering required to use high-power LEDs.”
“We have completed our own analysis to determine which high-power LEDs are
appropriate for our luminaires, and LUXEON® K2 has a clear edge in both performance and
engineering,” said Mr. Yvan Péard, CEO of AYRTON®. “These new LEDs delivered 30%
more light than products in the 3-watt range and exceeded our expectations on every
level.”
Key benefits of LUXEON® K2 LEDs include:
• The world’s best LED light output with
140 or more lumens in white,
outstripping the performance of other
power LEDs by 15 to 30% and significantly
lowering the cost per lumen.
• The industry’s highest maximum
junction temperature at 185°C,
allowing engineers to deliver more light in
current applications with existing thermal
designs by driving LEDs at higher currents.
This feature also makes it possible to
reduce or even eliminate heat sink
requirements, thereby lowering the cost of
system thermal design; and to build
applications for use in environments with
severe heat conditions.
• The market’s highest allowable drive
current at 1500mA and lowest
thermal resistance at 9° C/W, further reducing the cost per lumen by delivering
more light from the same package.
• The industry’s best moisture tolerance with a JEDEC Level 2a rating,
allowing for four weeks of unsealed factory floor life prior to preconditioning. Other
products are rated at JEDEC Level 4 at best, leaving only a 72-hour production
window after removal from their sealed production packaging.
Other advantages include simpler manufacturing through the use of surface mount
technology, lead-free package and assembly capabilities, and new alignment features and
datum reference points that facilitate precision assembly for automotive applications and
other products where tight positioning tolerance is critical.
LUXEON® K2 LEDs are rated for light output and drive current resulting in two series of
part numbers. Complete details are available in the LUXEON® K2 Datasheet at
www.lumileds.com.
LUXEON® K2 emitters can be ordered now from Lumileds Future Electronics (
www.lumiledsfuture.com) in eight colors, including white, green, blue, cyan, royal blue,
red, red-orange and amber.
