The graph shown below assumes that the system design employs good thermal management (thermalinterface material and heat sink) and may vary when poor thermal management is employed. Either solder pad shown in the MechanicalDimensions section on page 16 can be used as the Tc measurement point.Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends amaximum LES temperature of 140 C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 17 for moreinformation on LES temperature measurement.CMA1840240085 C, 2300 mA220020001800If (mA)1600140012001000125 C, 885 mA80060040020000255075100125150Case Temperature ( C)Copyright 2017-2019 Cree, Inc.

XLAMP CMA1840 LEDTHERMAL DESIGNThe CMA family of LED arrays can include over a hundred different LED die inside one package, and thus over a hundred different junctiontemperatures (TJ). Cree has intentionally removed junction-temperature-based operating limits and replaced the commonplace maximumTJ calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required toensure that the CMA LED is being operated within its designed limits. LES temperature measurement provides additional verification ofgood thermal design. Please refer to page 2 for the Operating Limit specification.There is no need to calculate for TJ inside the package, as the thermal management design process, specifically from solder point (TSP) toambient (Ta), remains identical to any other LED component. For more information on thermal management of Cree XLamp LEDs, pleaserefer to the Thermal Management application note. For CMA soldering recommendations and information on thermal interface materials(TIM), LES temperature measurement, and connection methods, please refer to the Cree XLamp CM Family LEDs soldering and handlingdocument.To keep the CMA1840 LED at or below the maximum rated Tc, the case to ambient temperaturethermal resistance (R c-a) must be at or below the maximum R c-a value shown on the followinggraph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmicscale.R j-cR j-cTcTcR timAs the figure at right shows, the R c-a value is the sum of the thermal resistance of the TIM (R tim)R c-aplus the thermal resistance of the heat sink (R hs).R hsCMA1840 - StandardTaTa100.00Maximum R c-a10.00Ta 25 CTa 55 C1.00Ta 85 CTa 105 urrent (mA)Copyright 2017-2019 Cree, Inc.
