Lighting-class LED arrays

10 July 2013 Opto-Electronics

Cree has extended the XLamp CXA family of integrated LED arrays with the new higher-light-output CXA2540 and CXA3050 LEDs. Optimised to simplify designs and lower system cost, the new LEDs deliver 5000 to over 10 000 lumens, enabling applications such as high-output track lights and downlights, outdoor area lighting and high-bay lighting.

The new CXA3050 LED is now the brightest member of the CXA family and can enable LED replacements for up to 100 W ceramic metal halide in spot lighting or up to 175 W pulse-start metal halide in high-bay and outdoor area lighting. The addition of the CXA3050 LED array also enables lighting manufacturers to expand their product portfolio with higher-lumen products.

The new CX2540 LED delivers high efficacy at 5000 lumens and 3000 K, and shares the same mechanical package as the existing CXA2520 and CXA2530 LEDs, giving manufacturers access to the same connector and optics solutions available previously.

The CXA2540 and CXA3050 LED arrays use the same proven 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 LEDs are available in EasyWhite colour temperatures, providing enhanced colour consistency for designs that use only one LED.
