Cree Announces New Generation of High Power LEDs
Higher temperature performance enables 60 percent reduction in heat sink size
Cree has introduced the XLamp MH-B LED, a new generation of high power LEDs that the company says delivers better performance and a more effective way to achieve low-cost systems than mid-power (MP) LEDs.
Using Cree's ceramic package technology, the XLamp MH-B LED is able to operate at higher temperatures than MP LEDs with no reduction in rated lifetime, enabling an impressive 60 percent 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 XLamp MH-B is optimised to simplify LED system designs for applications where multiple MP LEDs are currently used.
"Cree has once again invented a lighting-optimised solution that can lower my costs and decrease manufacturing times," said Frank Chen, technical director, Zhejiang Shenghui Lighting Co., Ltd. and Sengled Optoelectronics Co., Ltd. "While chip-on-board LEDs are an attractive alternative to MP LEDs in terms of reliability and cost, they aren't compatible with my automated manufacturing processes. The new XLamp(r) MH-B LED finally gives me a more reliable alternative to mid-power LEDs - I no longer have to compromise my brand and reputation to achieve a lower system cost."
Featuring Cree's EasyWhite technology and a small 5mm light emitting surface, the XLamp 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. As a single LED, the XLamp MH-B LED delivers up to 830 lumens at 175 mA 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," said Paul Thieken, 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 XLamp MH-B LED is available in 2700K - 6500K with high CRI options. Product samples are available now and production quantities are available with standard lead times.
