Cree's Chip-on-Board LEDs Provide Best In Class Lumen Density and Efficacy

Posted Oct 05, 2017 by Cree

Cree has launched a new family of XLamp CMA High Current LED Arrays that provide the best lumen density and efficacy for metal-based chip-on-board (COB) LEDs. Optimized for operation at high drive currents, the CMA LEDs deliver up to 2 ½ times the lumen density of Cree’s Standard Density CXA2 LEDs. The new CMA LEDs are compatible with the existing ecosystem of holders and optics for the CXA2 LED family, enabling lighting manufacturers to boost the lumen output of their products with minimal redesign.

The CMA LED Arrays feature a new innovative metal COB technology that delivers higher reliability than competing metal COBs. In addition, the CMA LEDs can be mounted directly to the heat sink, which eliminates the need for holders, simplifies the luminaire manufacturing process and reduces system cost.

The CMA LED family includes five LEDs with light emitting surface (LES) sizes ranging from nine to 23 mm to address a wide variety of applications. Featuring Cree’s EasyWhite bins, the XLamp CMA LED arrays are available in 2700 K - 6500 K CCTs with standard color options of 70, 80 and 90 CRI and premium color options that include high fidelity (98 CRI) and specialty color points. Product samples are available now, and production quantities are available with standard lead times. Click here to know more.
