Lumileds' LUXEON Q high-power LED boosts efficacy and flux in standard 3535 surface-mount package

Philips Lumileds of San Jose, CA, USA says that its new LUXEON Q LED delivers superior performance in a high-power emitter that serves as a direct drop-in replacement for products using the standard 3535 surface-mount package. LUXEON Q is the first high-power LED based on LUXEON flip-chip die, Lumileds’ high-performance chip-scale package (CSP) device architecture.

Efficacy for the LUXEON Q is 135lm/W at a correlated color temperature (CCT) of 5700K with a color rendering index (CRI) of 70 and 115lm/W at a CCT of 3000K and 80 CRI (at a junction temperature of 85˚C and drive current of 350mA). “Our LED is especially competitive when it’s driven harder,” notes Kathleen Hartnett, product line director for LUXEON Emitters. “For instance, at 1 Ampere, a flux of more than 300lm at an efficacy of 102lm/W at 85˚C is achieved in neutral white at 4000K. The high efficacy at high drive current of the LUXEON Q emitter is achieved as a result of the industry-leading wall-plug and conversion efficiency of Philips Lumileds next-generation CSP architecture,” she claims.

The LUXEON Q takes advantage of a fully developed ecosystem for 3535 components (including a wide range of optics) to speed time-to-market for omnidirectional indoor and outdoor luminaires. Applications include high-bay and low-bay luminaires, downlights, outdoor wall packs, replacement lamps and specialty luminaires. “Customers are starting with a familiar LED package and can quickly build their products from there using readily available optics and other compatible components,” says Hartnett.

The LUXEON Q emitter line is available in CCTs of 2700K, 3000K and 3500K at 80 CRI and CCTs of 4000K and 5700K at 70 CRI.
