Cree XQ-D White Series on Board
* Exceeding maximum ratings may damage the LED and cause potential safety hazards.
* Elevated operating temperatures can be expected to negatively impact the service life (lumen output)
* All data is related to entire assembly. Data reflects statistical mean values. Actual data may differ depending on variances
in the manufacturing process.
* End users need to take into account the lumen depreciation as the temperature rises with various thermal solutions
installed.
Note 1: Using continuously under elevated loads (i.e. the application of high temperature/current/voltage or a significant
change in temperature, etc.) may cause this product to significantly decrease in reliability even if the operating conditions are
within the
absolute maximum ratings.
Note 2: The thermal resistance from the LED junction to ambient temperature, Rth(j-a), should be kept below 100C/W so that
the LED is not exposed to a condition beyond the absolute maximum ratings.
Note 3: The temperature of the LED assembly must be measured at the TC-point according to EN60598-1 in a thermally
constant status with a temperature sensor or a temperature sensitive label.
