Lumileds' latest multi-die LEDs dramatically reduce the cost per lumen of outdoor, industrial and directional lights

Lumileds has announced the LUXEON 5050, a multi-die high-power package that delivers high performance and high throughput, enabling system designers to reduce the number and cost of LEDs for outdoor and indoor lighting. “The LUXEON 5050 is the best choice for outdoor and directional light applications that require high efficiency and low cost design and precise beam control,” said Ivan Tsoi, Product Manager, LUXEON 5050. For example, for outdoor applications, the source can provide greater than 155 lm/W at a typical drive current of 160 mA (4000 K, 70 CRI) and provide greater than 180 lm/W at 80 mA. For indoor spotlights and spotlights, the LUXEON 5050 achieves light efficiency greater than 130 lm/W at 160 mA (3000 K, 80 CRI).

The LUXEON 5050 is available in 70, 80 and 90 CRI and a wide range of color temperature configurations (2700K-5700K). The source is driven at 24V, enabling the use of cost-effective drives for all steady-state lighting applications. The surface mount device package of the LUXEON 5050 is equipped with thermal resistance (1.9K/W) to significantly reduce thermal management requirements. The LUXEON 5050 features a small circular illumination surface (4.6mm) that simplifies the optical design and makes it easier to achieve high center beam intensity.
