Lumileds releases Luxeon K2 LEDs

Luxeon K2 LEDs offer industry-leading light output, thermal and electrical properties.

Lumileds Lighting announce the 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 theLuxeon 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 Peard, 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 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 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 9deg 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.

Luxeon K2 emitters can be ordered now from Lumileds Future Electronics (www.lumiledsfuture.com) in eight colours, including white, green, blue, cyan, royal blue, red, red-orange and amber.
