CREE's New CMT High Current Series COB Brings 45% Lumen Density Increase And Higher Reliability.
- May 11, 2018 -

CREE (NASDAQ: CREE) announced the introduction of XLamp CMT LED, based on the latest metal substrate COB technology, using the universal COB appearance size, enriching the existing large current (High Current) product series.


The CREE high current COB adopts the innovative metal substrate technology, which can not only bring the highest 45% lumen density and the highest 17% light efficiency, but also achieve higher reliability. The new XLamp CMT LED currently provides more than 6000 hours of LM-80 data to help lighting manufacturers to quickly implement design upgrades, including track lights, down lights, outdoor lighting, and so on, to meet the requirements of DLC and Energy Star authentication applications.

Shawn Keeney, a technology manager for Ledra Brands, said: "by using the CREE CMT large current series COB, it can bring higher performance and easier integration, helping us to achieve a comprehensive combination of solutions in the design of lamps and lanterns. With the high performance and high reliability of CREE COB, we continue to maintain a leading position in the field of solid state lighting design.


CREE's release of CMT and the previously published CMA series LED, using the CREE new metal substrate COB technology, its appearance size and the vast majority of commercial production of the market on the market support holders and lens optics matching. CREE high current LED array (CMA and CMT), and CREE industry's leading standard density and high-density LED arrays (CXA and CXB) constitute the most abundant COB product combination in the industry. COB is directly installed on the radiator instead of another circuit board, which helps to simplify the lamp manufacturing process and reduce the system cost.


Dave Emerson, executive vice president and general manager of CREE LED, said: "CREE has been in the leading position in developing reliability and life standards, including IES LM-80 and TM-21. CREE strictly implements and fully maintains such standards and testing methods. Recently, the industry has reported the forged life data of individual enterprises, and our customers have maintained full confidence in CREE LED products, including the latest large current series COB. CREE LED products undergo rigorous testing to ensure that they can always provide reliable long-term performance.


CREE CMT high current series COB includes 10 new products, covering 3 kinds of luminous surface LES size (9.8 mm, 14.5 mm and 22 mm) to meet the needs of different applications. CREE CMT high current series COB uses EasyWhite color temperature division, related color temperature CCT range 2700 K - 6500 K, provides the color index CRI 70, 80, 90 standard options, and provides high color fidelity (CRI 98) and special color point of the excellent optical quality Premium Color option.


CMT is now available for sample application and can be produced at standard delivery time.
