New Cree CXA High-Density LED Arrays Have Unprecedented Lumen Density

Durham North Carolina-based Cree Inc., has launched three new LED arrays
with double the light output of existing CXA LED arrays without increasing the
size. According to Cree, the XLamp® CXA2590, CXA1850 and CXA1310 High-Density
LED Arrays have an unprecedented increase in lumen density. Cree asserts that
this new level of lumen density creates new levels of light intensity, enables
the complete replacement of ceramic metal halide (CMH) light sources, expands
the abilities of LED spotlights, and makes possible applications that could not
be addressed by previous LED technologies.

“The beauty of these new high-density LED arrays from Cree is that
they are helping us bring products to the market that currently don’t
said Mike Wang, vice president, lighting engineering, Edison
Price Lighting, Inc. “Never before have we been able to harness such
a large amount of light in such a small package, which can help us improve our
lighting designs and address a number of applications that we previously could

Cree says that the CXA2590 Array’s emission of more than 15,500 lumens from
a 19 mm light source, makes possible luminaires with the same center beam
candlepower (CBCP) and light quality of a 150-watt CMH light source at lower
power, with longer lifetime and better control. Delivering more than 9,000
lumens from a 12 mm light source, the CXA1850 LED Array provides the same CBCP
and light quality as 70-watt CMH while using half the power. Cree notes that
the CXA1310 LED Array delivers more than 2,000 lumens in a 6 mm light source.
According to Cree, this gives lighting manufacturers the opportunity to design
smaller, more efficient track lights, reduce the size of halogen replacements
by half and deliver twice the CBCP of CMH at 30 percent less power.

“Having access to such intense light sources without having to
account for lots of variation in size is a tremendous benefit to our product
design process,”
said Seok-Ki Park, CEO, Hwang-Duck Engineering Co.,
LTD. “We have the flexibility to increase our design options while
protecting our investment in ongoing product development.”

Like all CXA LED Arrays, the new arrays are characterized and binned at
85°C, available in ANSI White and EasyWhite® color temperatures (2700K –
6500K), and with CRI options of 70, 80 and 95. Samples of all three new
high-density LED arrays are available now and production quantities are
available with standard lead times.
