LED arrays deliver high lumen density

The advancement enables radically 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 high performance of the High Density LED arrays allows lighting manufacturers to reduce thermal, mechanical and optical costs at the system level.

For example, when combined with a 74mm diameter optic, the 3000K, 80 CRI CXB1520 High Density LED array delivers over 50,000 candela in a 10-degree beam while drawing only 40 watts.

This high lumen density allows lighting manufacturers to deliver the performance of a 70W 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 6mm LES, allowing similar reductions in size and power from traditional light sources.

Offering colour consistency for designs that use only one LED, Cree XLamp CXA2 High Density LED arrays are characterised and binned at 85°C, available in 2-, 3- and 5-step EasyWhite colour 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.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-recognised and feature a level 4 rating.
