oPEꢀAting LiMits
The maximum current rating of the CXA1820 depends 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. Please refer to the Mechanical Dimensions section
on page 14 for the location of the Tc measurement point.
Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree recommends a
maximum LES temperature of 135 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 15 for more
information on LES temperature measurement.

Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
measurements. See the Measurements section (page 16).
Cree XLamp CXA1820 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
Flux values @ 25 °C are calculated and for reference only.

Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
measurements. See the Measurements section (page 16).
Cree XLamp CXA1820 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
Flux values @ 25 °C are calculated and for reference only.

Measurements of CXA1820 at steady‑state operation at the given conditions, divided by
Flux measured during binning, which is a pulsed measurement at 550 mA at T = 85 °C.

For example, at steady‑state operation of Tc = 55 °C, IF = 850 mA, the relative luminous flux ratio is 140% in the chart below. A CXA1820
LED that measures 2100 lm during binning will deliver 2940 lm (2100 * 1.4) at steady‑state operation of Tc = 55 °C, IF = 850 mA.

XLamp® CXa1820 LED
thEꢀMAL 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 (T ). Cree has intentionally removed junction‑temperature‑based operating limits and replaced the commonplace maximum
J
T calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required to
J
ensure that the CXA LED is being operated within its designed limits. LES temperature measurement provides additional verification of
good thermal design. Please refer to page 2 for the Operating Limit specifications.
There is no need to calculate for T inside the package, as the thermal management design process, specifically from TSP to ambient
J
(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), LES temperature measurement, and connection methods, please refer to the Crꢀꢀ XLamp CX Family LeDs soldꢀring 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 CXA1820 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
Tc
R_j-c
Tc
graph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmic
scale.
R_tim
As the figure 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).
