LED maker Lumiledsof San Jose, CA, USA has launched 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 the superior choice for outdoor and directional lamp applications that demand high efficiency and cost-effective design together with precise beam control," reckons product manager Ivan Tsoi. For example, in outdoor applications, the source delivers luminous efficacy of 155lm/W at a typical drive current of 160mA (4000K, 70 CRI) and >180lm/W at 80mA. For indoor spotlights and downlights, the LUXEON 5050 can achieve 130lm/W at 160mA (3000K, 80 CRI).
The LUXEON 5050 is offered in a range of color temperatures (2700-5700K) at 70, 80 and 90 CRI (color rendering index). The source is driven at a voltage of 24V, enabling the use of low-cost and high-efficiency drivers for all solid-state lighting applications.
The surface-mount device package has a thermal resistance of 1.9K/W, which greatly reduces thermal management needs. Finally, the LUXEON 5050 utilizes a small round light-emitting surface (4.6mm), simplifying optical design and making it easier to achieve high center-beam candle power.
