Cree introduces new higher-light-output CXA2540 and CXA3050 LEDs

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA says it has extended its XLamp CXA family of integrated LED arrays with the introduction of new higher-light-output CXA2540 and CXA3050 LEDs. The new CXA LEDs deliver 5000 to over 10,000 lumens, enabling new applications such as high-output track lights and downlights, outdoor area lighting and high-bay lighting, says the firm.

CXA3050 is the brightest member of the CXA family and can enable LED replacements for up to 100-watt ceramic metal halide in spot lighting or up to 175 watt pulse-start metal halide in high-bay and outdoor area lighting. The CXA2540 delivers up to 20% higher efficacy at 5000 lumens and 3000K than competing LED arrays of similar size, says the firm. In addition, the CXA2540 shares the same mechanical package as the existing CXA2520 and CXA2530 LEDs, giving manufacturers access to the same connector and optics solutions available today.

“We really like the ease-of-use and high performance of the CXA family, and we’re looking for higher-lumen versions to address the high-bay lighting market,” says Jong Hyun Woo, chief project manager of ILSUNG Ltd. “The CXA3050 LED Array gives us the performance that we need together with the high reliability that Cree is known for to create compelling designs for our customers.”

CXA2540 and CXA3050 LED Arrays use the same package technology as the CXA1507 LED, which now has 6000 hours of LM-80 data published and is able to support TM-21 calculated lifetimes of greater than 130,000 hours at binning current and greater than 85,000 hours at maximum current.
To help lighting manufacturers get started designing with the new CXA integrated LED arrays, Cree has also published three CXA-based LED reference designs: PAR30 replacement lamp, six-inch downlight and retail track light. In addition, the new CXA LEDs are available in EasyWhite color temperatures.

XLamp CXA2540 and CXA3050 LED samples are available now.
