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 12 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.
