by Shane Henson — April 5, 2013—Lighting product manufacturer Cree Inc. recently added two new products to its XLamp CXA family of integrated light-emitting diode (LED) arrays, with both LEDs featuring higher light output.
According to the company, its CXA2540 and CXA3050 LEDs are optimized to simplify designs and lower system cost while delivering 5,000 to over 10,000 lumens and enabling new applications such as high output track lights and downlights, outdoor area lighting and high-bay lighting.
Cree says the CXA3050 LED is now 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 addition of the CXA3050 LED Array also enables lighting manufacturers to rapidly expand their product portfolio with higher lumen products.
The new CX2540 LED delivers up to 20 percent higher efficacy at 5,000 lumens and 3000K than competing LED arrays of similar size, Cree says. 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.
Cree adds that the CXA2540 and 3050 LED Arrays use the same proven package technology as the CXA1507 LED, which now has 6,000 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. This long-term calculated lifetime exceeds many other LED Arrays and plastic mid-power LEDs used today, the company says.
