Cree introduces new CMT high-current series COB light source


Cree has announced the launch of XLamp CMT LEDs, based on the latest metal substrate COB technology, using a common COB form factor to enrich the existing High Current product family.

Cree high-current COB adopts innovative metal substrate technology, which can not only bring up to 45% increase in lumen density and up to 17% increase in light efficiency, but also achieve higher reliability. The new XLamp CMT LED now provides over 6,000 hours of LM-80 data, helping lighting manufacturers quickly implement design upgrades including track lights, downlights, outdoor lighting, and more, to meet DLC and Energy Star certification applications.

Shawn Keeney, technical manager of Ledra Brands, said: "With the Cree CMT high-current series COB, we can achieve higher performance and easier integration, helping us to achieve a comprehensive portfolio of solutions in lighting design. With Cree COB With its high performance and reliability, we continue to maintain our leading position in solid-state lighting design."

Cree's CMT and previously released CMA high-current series LED adopts Cree's new metal substrate COB technology, and its appearance size is compatible with most commercially available stent holders and lens optics on the market. Cree high-current LED arrays (CMA and CMT) and Cree's industry-leading standard density and high-density LED arrays (CXA and CXB) constitute the industry's most extensive COB product portfolio. The COB is mounted directly on the heat sink without the need for additional circuit boards, helping to simplify the luminaire manufacturing process and reduce system costs.

According to Dave Emerson, executive vice president and general manager of Cree's LED Division, “Creo has been leading the way in the development of reliability and life-span standards including IES LM-80 and TM-21. We are fully committed to maintaining such standards and testing methods.Recently, the industry has reported the forged life data of individual companies, and our customers have maintained full confidence in Cree LED products including the latest high-current series COB. The harsh tests ensure that they always provide reliable long-term performance."

The Cree CMT high-current series COB includes 10 new products, covering three kinds of light-emitting surface LES dimensions (9.8 mm, 14.5 mm, and 22 mm) to meet the needs of different applications. Cree CMT high-current series COB adopts EasyWhite color temperature binning, correlated color temperature CCT range 2,700 K - 6,500 K, provides color rendering index CRI 70, 80, 90 standard options, and provides high color fidelity (CRI 98 ) and special color points for superior light quality Premium Color options.
