Cree, Inc. reported that it added the new CMT LEDs to the XLamp® High Current LED Array family. The new CMT LEDs employ Cree’s latest metal-based chip-on-board (COB) LED technology with the most prevalent COB form factors. The LEDs boast up to 45 percent more lumen density and up to 17 percent higher efficacy, than all Cree® XLamp High Current LED Arrays. Cree says its novel metal substrate technology increases the reliability of the LEDs beyond that of competing metal COBs.
The company also says that the with more than 6,000 hours of LM-80 data available, the expanded family of LEDs allows lighting makers to quickly upgrade their designs for DesignLights Consortium® and ENERGY STAR® eligible applications, including downlights, as well as outdoor and track lighting.
The CMT LEDs and the company’s recently debuted High Current CMA LEDs which both use Cree’s new metal-based COB technology, are available in form factors that are compatible with most commercially available holders and optics.
CMA and CMT LEDs and the Standard and High-Density CXA and CXA2 Make up Broad COB Portforlio
The newly expanded High Current LED Array family (CMA and CMT LEDs) join Cree’s Standard Density and High-Density families (CXA and CXA2). According to Cree, combined these LEDs make up the broadest portfolio of COB LEDs from a single company. COB LEDs mount directly onto a heat sink without needing a separate circuit board, thereby simplifying the luminaire production and reducing system cost.
“Cree is a long-standing leader in developing reliability and lifetime standards for LEDs, such as IES LM-80 and TM-21, and we remain fully committed to upholding these methods,” said Dave Emerson, executive vice president and general manager, Cree LEDs. “In light of recent reports of some companies falsifying lifetime data, our customers can remain confident that Cree LEDs, including our latest High-Current COB family, undergo rigorous testing to allow them to consistently deliver reliable long-term performance.”
The CMT LED family includes 10 LEDs measuring 9.8 mm by 14.5 mm by 22 mm, across three light emitting surface (LES) sizes. The XLamp CMT LEDs come in Cree’s EasyWhite® bins, in correlated color temperatures from 2700K-6500K.
“With the new High Current CMT LEDs, Cree has given us a full portfolio of solutions for our upcoming luminaire designs, in terms of both performance and ease of integration,” said Shawn Keeney, technology manager, Ledra Brands, a maker of innovative, specification-grade LED lighting fixtures and systems. “By choosing Cree, we know that we are leveraging the highest performance and best long-term reliability for COB LEDs to continue our leadership in solid state lighting design.”
Standard color options of 70, 80 and 90 CRI and premium color options including high fidelity (98 CRI) and specialty color points are available. Product samples are currently available, and production quantities are available with standard lead times.
