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.
“Since the new high-current CMA LED arrays are compatible with the standard-density CXA2 LED family, we can easily deliver more visual impact while maintaining the same optics options and color quality choices that our customers are looking for,” comments Andrea Gallucci, head of optics & electronics at Italian lighting firm Artemide S.p.A. “These new CMA LEDs will speed up the pace of performance enhancements within both our iconic and innovative luminaire designs.”
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.
The CMA LED family includes five LEDs with light-emitting surface (LES) sizes ranging from 9mm to 23mm to address a wide variety of applications. Featuring Cree’s EasyWhite bins, the XLamp CMA LED arrays are available in correlated color temperatures (CCTs) of 2700-6500K with standard color options of 70, 80 and 90 CRI (color rendering index) 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.
