Lumileds Multi-die Emitter Drives Down Cost-per-lumen in Outdoor, Industrial and Directional Lamps

LUXEON 5050_Top_640x640_labelLumileds has introduced the LUXEON 5050, a multi-die high power package
that provides high flux at high efficacy, enabling system designers to reduce LED count and cost in outdoor and indoor fixtures. “The LUXEON 5050 is designed for outdoor and directional lamp applications that demand high efficiency and cost effective design together with precise beam control,” said Ivan Tsoi, product manager. In outdoor applications, the source delivers more than 155 lumens per watt at a typical drive current of 160 miliangstroms and more than 180 luments per watt at 80 milliangstroms. For indoor spotlights and downlights, the it can achieve more than 130 lumens per watt at 160 milliangstroms, said Tsoi.

The LUXEON 5050 is offered in a range of color temperatures and is driven at 24V, which enables the use of low cost and high efficiency drivers for all solid state lighting applications. Its surface mount device package features a thermal resistance of 1.9 kilowatt,which greatly reduces thermal management needs. It utilizes a small round light emitting surface (4.6 mm) which simplifies opticaldesign and makes it easier to achieve high center beam candle power.
