Cree XLamp CXA LED Arrays Product Family Overview

October 12, 2019

At Cree our mission is to lead the LED
Lighting Revolution one way we do that is by manufacturing a
variety of LED components that lighting designers and engineers
like you can easily use to create LED lights powered by Cree. We have four
major types of LED components: discreets, arrays, integrated arrays, and modules. This video will focus
on our revolutionary Xlamp CXA integrated arrays. There are many
benefits and practical solutions to using CXAs to design your next light. In an integrated array, LED’s are
positioned into a single uniform light source and come pre-attached to a printed circuit board. So all you have to do is attach power to
the CXA and you can focus on designing the rest
of your light. This eliminates some time-consuming
steps in the design process When choosing the right CXA for your
project, there are two main differentiating
factors to think about: density and size. Standard density CXAs
optimize lumens per dollar and high-density CXS optimize Center
Beam Candle Power per dollar. We offer small arrays with a Light
Emitting Surface of 14 millimeters wide or less and large
arrays that are wider than 14 millimetres High-density CXAs are great for
high-power directional lighting. And, standard density CXAs are
optimized for cost and performance across all lighting applications. Small
high-density CXAs can replace high output track lights. Large high density CXAs can replace high
ceiling downlights and stage spotlights. Standard Density CXAs can replace
anything from track lights and down lights to high bay lights and wall packs. So, you can see that CXAs can offer a wide variety of solutions to your lighting needs Let’s focus on high-density arrays for a
moment. High-density CXAs redefine performance
for LED spotlights was significantly reduced size and
tighter beam angles. And HD Arrays use less power for the same quality light coming in 80 and 95 CRI options. For instance, the high-density CXA1250
can give you the same Candela power as the standard density CXA2530 but from a much smaller light source and
using 66 percent less energy. Let’s say you’re trying to build a
high-output track light and you know you needed to be cool white. And let’s say you want to have a lumen output of about 3500. Looking at this chart you can see that
the CXA1850 gives you the best performance at this
lumen level. Using this chart you can find the best CXA for your
lighting needs. Compared to a 39w CMH lamp, the CXA1520 design prototype has
better performance and cost with lower power, lower temperature, no explosion risk,
longer lifetime, instant on, and instant restrike. Also, the XLamp CXA1310 prototype offers
two times the Candela at 66 percent less power than a CMH PAR20. Also, the XLamp CXA1310 prototype give 70 watt performance at 35 watt
power consumption levels. Now let’s talk about standard density
arrays. Standard density arrays are optimal for
everything from small spotlights to warehouse and outdoor area lights. For
each size Cree has industry-leading performance
and excellent reliability. And you can use our charts to find the
most efficient standard density CXA for your lighting needs. Additionally there are several
third-party options for connectors for CXAs as well as lots of options for optics
and thermal interface materials. And you can speed time to market by
leveraging the Cree LED modules ecosystem with available drivers and heatsinks
for CXAs See how you can utilize CXAs for your
next lighting design. join Cree in the LED Lighting
