e characteristic plotted the temperature characteristics.
Figure 4 LED voltage characteristics of the temperature characteristics of the LED is assumed to supply constant current Io, the junction temperature of T1, the voltage V1, and when the junction temperature rise for the T2, the voltage characteristic left, the current Io is not change, voltage becomes V2. Is the temperature difference between the two voltage removed, the temperature coefficient can be obtained in order to mV / oC said. F
