LIGHTimes News Staff
February 17, 2015...Durham, North Carolina-based Cree, Inc. has added the CXA2 to its CXA LED
array family. Cree says that in the same form factor, the CXA2 provides up to
33 percent higher efficacy. The improvement in lumen density reportedly comes
from Cree's SC5 Technology Platform, which Cree claims reduces system size and
cost. The new chip-on-board (COB) LED arrays are suited for applications
including downlight, track, and outdoor lighting.
“We are working together with Cree to evaluate their latest COB
technology,” said Massimo Parravicini, R&D director of Reggiani
Illuminazione. “I believe that the new CXA2 LED arrays, which deliver
excellent performance in such small LES [light emitting surface], would be a
great solution for the new generation of indoor luminaires we are currently
Cree points out that with the new CXA2 LED arrays, lighting manufacturers
can achieve the same or better performance with a smaller light emitting
surface (LES) compared to earlier products. For example, a 3800 lumen output
from a larger 19 mm LES LED can be replaced with a smaller 12 mm LES LED.
According to Cree, the smaller LES results in up to 60 percent system cost
savings through lower LED heat sink, mechanical, and optical material costs.
“The new CXA2 LED arrays make it possible for lighting designers
to radically reduce system costs in the next generation of industry-leading
lighting products," said Dave Emerson, vice president and general manager
for Cree LEDs. "By giving our customers innovative LED solutions instead of
incremental LED improvements, we enable them to differentiate their products in
the marketplace and deliver more value to their end customers.”
CXA2 LED arrays share the same physical design as earlier arrays, allowing
lighting manufacturers to use the existing electrical, mechanical, and optical
components to reduce time to market without additional cost. LM-80 data is
available for all CXA2 LED arrays for lighting manufacturers seeking ENERGY
STAR® qualification. The CXA2 LED arrays are also UL®-recognized components and
feature a level 4 rating.
Through improvements in the light conversion process, Cree has reduced
LED-to-LED color variations. Among other options, the CXA2 LED arrays come in
2-step and 3-step EasyWhite® bins with correlated color temperatures of 2700K
to 6500K and color rendering index (CRI) options of 70, 80, and 90. The arrays
also come with multiple voltage options in LES from 6-30mm with a lumen output
from 250 to 19,000 lumens.
