Multi-die package LED provides precise beam control and high luminance

Now stocked by Mouser, the Lumileds LUXEON 5258 LED is engineered to serve as a single 4.8mm optical light source. The multi-die package LED provides precise beam control and high luminance from a single package. The SMD devices are available in 24V and 96V options for a variety of directional LED lighting applications. The 5258 LEDs provide high-flux and high-efficacy, improving the quality of light while avoiding the showerhead effect common with distributed, multi-die solutions. The devices are offered in two voltage versions of either 24V or 96V, and are available in warm white color temperature ranges of 2700K and 3000K. The color rendering index (CRI) of the LUXEON 5258 is rated at 80, and the devices offer hot-color targeting to ensure that the LEDs are within color target at ANSI application conditions of 85C. All the LUXEON 5258 devices are also binned with either a single 3-step or 5-step MacAdam ellipse to ensure colour uniformity, and are compatible with low-cost and high-efficiency drivers. The LEDs offer some of the best efficacy and flux metrics in the market today, providing superior reliability and droop curve over other competing solutions. The LUXEON 5258 24V solutions provide a luminous flux of 500 lumens (typical) at an efficacy of up to 125 lm/W, while the 96V solutions provide 458 lumens (typical) at an efficacy of up to 118 lm/W. The multi-die emitter on the LUXEON 5258 devices enable cost effective designs for PAR 16, PAR 20, MR16 and GU10 lamps. The 5258 LEDs are available in a 5.2mm x 5.8mm surface-mount package, and are aimed at a broad array of general purpose lighting and directional lighting applications including retrofit lamps, spotlights and luminaires.
