LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has introduced the XLamp MH-B LED, a new generation of high-power LEDs that delivers better performance and a more effective way to achieve low-cost systems than mid-power (MP) LEDs.
Using Cree’s high-reliability ceramic package technology, the MH-B LED is able to operate at higher temperatures than MP LEDs with no reduction in rated lifetime, enabling a 60% reduction in heat-sink size and cost. Using up to 26 times fewer LEDs than MP LEDs to achieve the same level of performance, the MH-B is optimized to simplify LED system designs for applications where multiple MP LEDs are currently used.
“Cree has once again invented a lighting-optimized solution that can lower my costs and decrease manufacturing times,” comments Frank Chen, technical director at Zhejiang Shenghui Lighting Co Ltd and Sengled Optoelectronics Co Ltd. “While chip-on-board (CoB) LEDs are an attractive alternative to MP LEDs in terms of reliability and cost, they aren’t compatible with my automated manufacturing processes,” he adds. “The new XLamp MH-B LED finally gives me a more reliable alternative to mid-power LEDs.”
Featuring Cree’s EasyWhite technology and a small 5mm light-emitting surface, the MH-B provides many system benefits over arrays of MP LEDs, including tighter beam angles, simpler optics, a more traditional appearance and easier color consistency, claims Cree. As a single LED, the MH-B LED delivers up to 830 lumens at 175mA and can also be used in arrays to address higher-lumen applications that require low cost and high reliability, such as high-bay, outdoor area and downlights.
“The new XLamp MH-B LED combines the reliability and manufacturability of Cree’s high-power LEDs with the simplicity and performance of our CXA LED arrays,” says Paul Thieken, Cree’s director of marketing, LED components. “MH-B introduces a new technology platform that gives customers the best of both technologies, while avoiding the limitations of mid-power LEDs.”
The MH-B LED is available in correlated color temperatures (CCTs) of 2700–6500K with high color rendering index (CRI) options. Product samples are available now and production quantities are available with standard lead times.
