Cree launches XB-D lighting-class LED on new platform that doubles lumens-per-dollar

Cree Inc of Durham, NC, USA has launched the XLamp XB-D LED. The first LED based on a new technology platform, the XB-D ushers in what is claimed to be a new era of price-performance for lighting-class LEDs. Cree adds that the LED can further simplify designs, ultimately removing a key barrier to widespread LED implementation—up-front system cost.

Leveraging Cree’s proven silicon carbide (SiC) technology and expertise, the XB-D LED delivers luminous flux and efficacy, effectively, up to 139 lumens and 136 lumens per watt in cool white (6000K) or up to 107 lumens and 105 lumens per watt in warm white (3000K), both at a drive current of 350mA and a temperature of 85°C.

Cree claims that the XB-D LED delivers twice the lumens-per-dollar of other LEDs, in the industry’s smallest lighting-class footprint of 2.45mm x 2.45mm. The XB-D LED is 48% smaller than the XLamp XP package and suitable for lighting applications where high lumen density and compact light sources are required. The developments behind this next generation of lighting-class LEDs can enable significantly lower prices for LED lighting products by using up to three times fewer LEDs, three times fewer optics, and substantially smaller circuit boards than current designs, the firm adds.

“With this new platform Cree has fundamentally redefined the price-performance paradigm for our components customers,” reckons Mike Watson, senior director of marketing, LED components. “It’s not enough to just make LEDs brighter—it’s also about improving product payback and market acceptance of LED lighting.”

XB-D LEDs are also compatible with most existing XP family secondary optics, which can speed the optical design process and create direct cost savings for existing XP family-based designs.

Samples are available immediately and production volumes are available with standard lead times.
