The 35V Cree XLamp® CXA1520 is the newest High Density (HD) LED array, featuring a 9-mm optical source and enabling a new generation of products that delivers the same intensity and light quality as 20-W ceramic metal halide (CmH). The new HD class of 1520 CXA arrays provide unrivaled lumen density by packing hundreds of die into the light emitting surface (LES), that can reduce system cost for LED spotlights. We offer this LED in warm-white and cool-white.
Thermal Design The CXA 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 CXA LED is being operated within its designed limits. Please refer to page 2 for the Operating Limit specification.
Cree has measured the temperature at the bottom of the package, commonly referred to as the solder point (TSP), and found this value to be equivalent to the temperature at the Tc location at the top of the package once the LED has reached thermal equilibrium. There is no need to calculate for TJ inside the package, as the thermal management design process, specifically 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 XLamp Thermal Management application note. For CXA soldering recommendations and more information on thermal interface materials (TIM) and connection methods, please refer to the Cree XLamp CXA Family LEDs soldering and handling document. The CXA LED Design Guide provides basic information on the requirements to use Cree XLamp CXA LeDs successfully in luminaire designs.
Lumen Maintenance Projections Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen maintenance. For information on the specific LM-80 data sets available for this LED, refer to the public LM-80 results document.
Please read the XLamp Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature.
