Cree doubles light output from high-density LED arrays

February 13, 2014 // By Graham Prophet
Cree says its CXA high-density LED arrays offer unmatched lumen density, to access new designs and applications for LED lighting

Three new LED arrays – the XLamp CXA2590, CXA1850 and CXA1310 High-Density LED Arrays – double the light output of existing standard-density CXA LED arrays without increasing the size. This increase in lumen density delivers new levels of light intensity, which enables the complete replacement of ceramic-metal-halide (CMH) light sources, expands the possibilities of LED spotlights and enables applications that could not be addressed by previous LED technologies.

By emitting more than 15,500 lumens from a 19-mm light source, the CXA2590 LED Array enables luminaires with the same centre-beam candlepower (CBCP) and light quality of a 150-W CMH light source at lower power level, with longer lifetime and with better control. Delivering more than 9,000 lumens from a 12-mm light source, the CXA1850 LED Array enables lighting solutions with the same CBCP and light quality as 70-W CMH while using half the power. The CXA1310 LED Array provides more than 2,000 lumens in a 6-mm light source, which allows lighting manufacturers to design smaller, more-efficient track lights, reduce the size of halogen replacements by half and deliver twice the CBCP of CMH at 30% less power.

The extended CXA product family helps lighting manufacturers address a wide range of lighting applications from small-form-factor halogen and CMH, to sports and stadium lighting, Cree says. Lighting manufacturers can also take advantage of the CXA’s ability to increase light output without increasing size.

Offering optimum colour consistency for designs that use only one LED, Cree XLamp CXA LED Arrays are characterised and binned at 85°C, available in ANSI White and EasyWhite colour temperatures (2700 K – 6500 K), and CRI options of 70, 80 and 95.
