Operating Limits The maximum current rating of the CXA2540 is dependent 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.

For example, at steady-state operation of Tc = 55 °C, IF = 1760 mA, the relative luminous flux ratio is 140% in the chart below. A CXA2540 LED that measures 4600 lm during binning will deliver 6440 lm (4600 * 1.4) at steady-state operation of Tc = 55 °C, IF = 1760 mA. 180% 160% Relative Luminous Flux 140% 120% Tc = 25 °C 100% Tc = 55 °C 80% Tc = 85 °C Tc = 105 °C 60% 40% 20% 0% 400 740 1080 1420 1760 2100 Current (mA) Copyright © 2013-2016 Cree, Inc.

CRONIN CHECK APPROVED MATERIAL FINAL PROTECTIVE FINIS 63 2 XLamp ® CXA2540 LED 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. There is no need to calculate for TJ inside the package, as the thermal management design process, specifically from solder point (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 CXA 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 CXA LEDs successfully in luminaire designs. To keep the CXA2540 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 R_j-c R_j-c scale. Tc Tc As the figure at right shows, the R_c-a value is the sum of the thermal resistance of the TIM (R_tim) R_tim graph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmic R_c-a plus the thermal resistance of the heat sink (R_hs).

These measurements will change over time based on a number of factors that are not within Cree’s control and are not intended or provided as operational specifications for the products. Calculated values are provided for informational purposes only and are not intended as specifications. Pre‑Release Qualification Testing Please read the LED Reliability Overview for details of the qualification process Cree applies to ensure long-term reliability for XLamp LEDs and details of Cree’s pre-release qualification testing for XLamp LEDs. Lumen Maintenance 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 Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing and forecasting. Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature. RoHS Compliance The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to as the threshold limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2011/65/EC (RoHS2), as implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree representative or from the Product Documentation sections of www.cree.com. REACh Compliance REACh substances of very high concern (SVHCs) information is available for this product. Since the European Chemical Agency (ECHA) has published notice of their intent to frequently revise the SVHC listing for the foreseeable future, please contact a Cree representative to insure you get the most up-to-date REACh SVHC Declaration. REACh banned substance information (REACh Article 67) is also available upon request. UL® Recognized Component Level 4 enclosure consideration. The LED package or a portion thereof has been investigated as a fire and electrical enclosure per ANSI/ UL 8750. Vision Advisory WARNING: Do not look at an exposed lamp in operation. Eye injury can result. For more information about LEDs and eye safety, please refer to the LED Eye Safety application note. Copyright © 2013-2016 Cree, Inc. All rights reserved.
