Lumileds today 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 the superior choice for outdoor and directional lamp applications that demand high efficiency and cost effective design together with precise beam control,” said Ivan Tsoi, Product Manager for the LUXEON 5050. For example, in outdoor applications, the source delivers ˃155 lm/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 ˃130 lm/W at 160mA (3000K, 80 CRI).
The LUXEON 5050 is offered in a range of color temperatures (2700K-5700K) at 70, 80 and 90 CRI. The source is driven at 24V, which enables the use of low cost and high efficiency drivers for all solid state lighting applications. The LUXEON 5050’s surface mount device package features a thermal resistance (1.9 K/W), which greatly reduces thermal management needs. Finally, the LUXEON 5050 utilizes a small round light emitting surface (4.6 mm) which simplifies optical design and makes it easier to achieve high center beam candle power.
