OPERATING LIMITS The maximum current rating of the CMB2550 LED 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. Either solder pad shown in the Mechanical Dimensions 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 LED recommends a maximum LES temperature of 140 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 17 for more information on LES temperature measurement.

CLD-DS287 REV 0 9 RELATIVE LUMINOUS FLUX The relative luminous flux values provided below are the ratio of measurements of the CMB2550 LED at steady‑state operation at the given conditions, divided by the flux measured during binning, which is a pulsed measurement at 1400 mA at TJ = 85 °C. For example, at steady‑state operation of Tc = 25 °C, IF = 1600 mA, the relative luminous flux ratio is 125% in the chart below. A CMB2550 LED that measures 6160 lm during binning will deliver 7700 lm (6160 * 1.25) at steady‑state operation of Tc = 25 °C, IF = 1600 mA.

CLD-DS287 REV 0 17 THERMAL DESIGN The CMB 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 LED has intentionally removed junction‑temperature‑based operating limits and replaced the commonplace maximum TJ calculations with maximum ratings based on forward current (I F) and case temperature (Tc). No additional calculations are required to ensure that the CMB 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 specification. There is no need to calculate for TJ inside the package, as the thermal management design process, specifically from solder point (T SP) to ambient (Ta), remains identical to any other LED component. For more information on thermal management of XLamp LEDs, please refer to the Thermal Management application note . For CMB soldering recommendations and more information on thermal interface materials (TIM), LES temperature measurement, and connection methods, please refer to the XLamp CM Family LEDs soldering and handling document. To keep the CMB2550 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 the TIM (R_tim) plus the thermal resistance of the heat sink (R_hs).

CLD-DS287 REV 0 18 NOTES Measurements The luminous flux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specifications only and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number of factors that are not within Cree LED’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 or provided as specifications. Pre-Release Qualification Testing Please read the LED Reliability Overview for details of the qualification process Cree LED applies to ensure long‑term reliability for XLamp LEDs and details of Cree LED’s pre‑release qualification testing for XLamp LEDs. Cree LED did not perform Room Temperature Operating Life (RTOL) testing on the CMB2550 LED. Lumen Maintenance Cree LED 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 LED’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. 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.
