Cree expands chip-on-board LED portfolio with high-current XLamp LED arrays

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has launched a family of XLamp CMA high-current LED arrays that provide what is claimed to be 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 2.5 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 metal COB technology that delivers what is claimed to be 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.
