Cree® XLamp® CXB1310 LED
PRODUCT DESCRIPTION
Cree CXB1310 High Density (HD) LED
arrays are the next generation of high
lumen density LED arrays. Incorporating
elements of Cree’s SC5 Technology™
Platform, the CXB1310 HD LED arrays
deliver the most lumens in the industry
for their light-emitting surface (LES)
size, enabling radically new and
differentiated LED lighting form factors
for applications like tracks, lamps
and downlights. The industry-leading
performance of the CXB1310 HD LED
arrays allows lighting manufacturers
to develop compact, cutting edge
products that deliver high performance
and energy savings.
The CX Family LED Design Guide
provides basic information on the
requirements to use the CXB1310 HD
LED array successfully in luminaire
designs.

OPERATING LIMITS
The maximum current rating of the CXB1310 is dependent on the case temperature (Tc) when the LED has reached thermal equilibrium
under steady-state operation. The graphs shown below assume 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16forthelocationoftheTcmeasurementpoint.

XLamp® CXB1310 LED
THERMAL DESIGN
The CXB family of LED arrays can include over a hundred different LED die inside one package, and thus over a hundred different junction
temperatures (TJ). Cree has intentionally removed junction-temperature-based operating limits and replaced the commonplace maximum
TJ calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required to
ensuretheCXBLEDisbeingoperatedwithinitsdesignedlimits.Pleaserefertopage15fortheOperatingLimitspecication.
There is no need to calculate for TJinsidethepackage,asthethermalmanagementdesignprocess,specicallyfromTSP to ambient (Ta),
remains identical to any other LED component. For more information on thermal management of Cree XLamp LEDs, please refer to the
Thermal Management application note. For CXB soldering recommendations and more information on thermal interface materials (TIM)
and connection methods, please refer to the Cree XLamp CX Family LEDs soldering and handling document. The CX Family LED Design
Guide provides basic information on the requirements to use Cree XLamp CXB LEDs successfully in luminaire designs.
To keep the CXB1310 LED at or below the maximum rated Tc, the case to ambient temperature
thermal resistance (R_c-a) must be at or below the maximum R_c-a value shown on the following
graphs, depending on the operating environment. The y-axis in the graph is a base 10 logarithmic
scale.
Asthegureatrightshows,theR_c‑avalueisthesumofthethermalresistanceoftheTIM(R_tim)
plus the thermal resistance of the heat sink (R_hs).
