which as long as a data inaccuracy will affect the accuracy of the test. Figure 3 shows the thermal resistance of each LED to the radiator diagram. Which combined a lot of resistance, making it a more limited accuracy. That is, the heat sink from the surface temperature measured to infer more accurate junction temperature difference.
Figure 3 LED to the heat sink thermal resistance diagram Fortunately, each an indirect method of measuring temperature, it is to measure voltage. Then the junctio
