CXA1820 LED
ProDuCt DEsCriPtion
The XLamp
®
CXA1820 LeD array expands
Cree’s family of high‑flux, multi‑die
arrays, offering high performance in an
easy‑to‑use platform. With XLamp LED
lighting‑class reliability, the CXA1820’s
uniform emitting surface enables both
directional and non‑directional lighting
applications and luminaire designs.
Available in 2‑step, 3‑step and 4‑step
color consistency, and featuring a
12‑mm optical source, the CXA1820
brings new levels of flux and efficacy to
this form factor.
The
CX Family LED Design Guide
provides basic information on the
requirements to use the CXA1820 LED
successfully in luminaire designs.

oPErAting LiMits
The maximum current rating of the CXA1820 depends on the case temperature (Tc) when the LED has reached thermal equilibrium under
steady‑state operation. The graph shown below assumes that the system design employs good thermal management (thermal interface
material and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions section
on page 14 for the location of the Tc measurement point.
Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends a
maximum LES temperature of 135 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 15 for more
information on LES temperature measurement.
