Current Derating Curves
The graph below illustrates the relationship between the system thermal resistance, drive current, and
ambient temperature. Please note that absolute maximum ratings requirements, including that of
maximum case temperature, must be adhered to in the system design. The thermal resistance values
indicated in Figure 17 and 18 are total system values (junction to ambient) including the thermal
resistance of the LED Array. Individual LED Array thermal resistance values are listed in Table 3.
