LEDs claim new industry benchmark
Luxeon K2 LEDs claim new industry benchmarks in a variety of areas including light output, temperature tolerance and drive current.
Lumileds Lighting reckons its Luxeon K2 LEDs 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

High-power LEDs boast double the light output
The increased drive current capability of Luxeon K2 LEDs enables development of brighter LED-based lighting applications than ever before.
Power LEDs offer more white options
Expanded range of white emitters means the Luxeon K2 series is now available with correlated colour temperatures from 2670 to 10,000K.
"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 Yvan Peard, CEO of Ayrton.

Bright showing from long-life LEDs
The Luxeon III is a new high-power 100kh-life LED that generates typical light output of 65 and 80 lumen from a single emitter at 700 and 1000mA operation, respectively.
RGB LED backlight is ready to use
The Luxeon DCC is billed as the first fully assembled LED-based RGB light source for use as an alternative to cold cathode fluorescent lamps in LCD backlights.
"These new LEDs delivered 30% more light than products in the 3W range and exceeded our expectations on every level".
Luxeon K2 LEDs claim world's best LED light output with 140 lumen or more in white, outstripping the performance of other power LEDs by 15 to 30% and significantly lowering the cost per lumen.
They feature industry's highest maximum junction temperature at 185C, 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 heatsink requirements, thereby lowering the cost of system thermal design; and to build applications for use in environments with severe heat conditions.
The new LEDs also have market's highest allowable drive current at 1500mA and lowest thermal resistance at 9C/W, further reducing the cost per lumen by delivering more light from the same package.
Also claimed is 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.
Devices are available in eight colours: white, green, blue, cyan, royal blue, red, red-orange and amber.
