New Cree XLamp CXA2 High Density LEDs Double Lumen Output

April3_Cree CXA2 HD_IMG_2544Cree, Inc. has introduced the XLamp CXB1310 and CXB1520 High Density LED arrays. Incorporating elements of Cree’s SC5 Technology Platform, the new LEDs deliver the highest lumen density at 6 mm and 9 mm, the most lumens in the industry for their LES [light emitting surface] sizes.  The advancement enables new and differentiated LED lighting form factors for applications like track lights, lamps and downlights. For example, the CXB1520 LED packs the lumen output of seven 60-watt replacement lamps into an area much smaller than a dime, allowing lighting manufacturers to put more light where it is intended at a lower system cost.

“The CXB1310 High Density LED array delivers an impressive amount of light in a small package,” said Massimo Parravicini, R&D director of Reggiani Illuminazione. “The high lumen density of the CXB1310 LED will allow us to offer LED designs with performance and form factors previously impossible.”

The high performance of the CXA2 High Density LED arrays allow lighting manufacturers to reduce thermal, mechanical and optical costs at the system level. For example, when combined with a 74 mm diameter optic, the 3,000K, 80 CRI CXB1520 High Density LED array delivers over 50,000 candela in a 10° beam while drawing only 40 watts. This high lumen density allows lighting manufacturers to deliver the performance of a 70 W ceramic metal halide (CMH) PAR38 lamp through a much smaller PAR20-size optic using 43 percent less power. The CXB1310 High Density LED array delivers up to 3,200 lumens in a 6 mm LES, allowing similar reductions in size and power from traditional light sources.

“The CXB1520 High Density LED allows us to deliver downlights that provide up to 2,700 lumens with just 28 watts in a very small 4” trim platform. What was previously only possible in much larger platforms with much higher wattage requirements is now made possible in our VF series Specification Grade Luminaire Downlight product line using Cree’s CXB1520 High Density LEDs,” said Justin Weaver, Vice President Engineering, LF Illumination. “The very high efficacy of the CXB1520 High Density LED also allows us to move many of our products that at one time were only possible with active cooling solutions to passive solutions, simplifying our design and lowering our system costs significantly.”

Offering the industry’s best color consistency for designs that use only one LED, Cree XLamp CXA2 High Density LED arrays are characterized and binned at 85°C, available in 2-, 3- and 5-step EasyWhite color temperatures (2700K – 6500K), and CRI options of 70, 80 and 90. The CXB1310 and CXB1520 LEDs have LM-80 long-term test data available immediately, delivering reported L90 lifetime projections of at least 36,300 hours at 85°C and 105°C.

“Cree pioneered high lumen density LED arrays, and we continue to push the boundaries of LED performance, consistently achieving what no other LED manufacturer has been able to achieve,” said Dave Emerson, vice president and general manager for Cree LEDs. “The industry-leading performance of the new CXA2 High Density LED arrays allows our customers to develop differentiated products that deliver high performance and energy savings through better LED technology.”

The CXA2 High Density LED arrays are available in the same form factor as the CXA LED arrays, allowing the use of existing optics, holders and drivers. The CXA2 High Density LED arrays are also UL-recognized and feature a level 4 rating.  Product samples are available now, and production quantities are available with standard lead times.
