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. Please refer to the Mechanical Drawings section on page 16 for the
location of theCXA2540
Tc measurement point.

Relative Luminous Flux
The relative luminous flux values provided below are the ratio of:
• Measurements of CXA2540 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 1100 mA at TJ = 85 °C.
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.

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.
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 at
www.cree.com/xlamp_app_notes/thermal_management. 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 at www.cree.com/xlamp_app_notes/CXA_SH.
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 graph, depending on the operating environment. The
y‑axis in the graph is a base 10 logarithmic scale.
As the figure at right shows, the R_c-a value is the sum of the thermal resistance of
R_tim
R_c-a
the TIM (R_tim) plus the thermal resistance of the heat sink (R_hs).

XLamp CXA2540 LED
Notes
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 at www.cree.com/xlamp_app_notes/LM80_results.
Please read the XLamp Long-Term Lumen Maintenance application note at www.cree.com/xlamp_app_notes/lumen_
maintenance for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal
Management application note at www.cree.com/xlamp_app_notes/thermal_management 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.
