Published Date: November-16

Description

The output power (P0) of a GaAs LED is a function of forward current (IF). As this forward current increases, the output power will also increase. This forward current flowing through the LED generates heat (P0) which causes the junction temperature (ƟI) of the diode to increase. As the junction temperature increases, the output power decreases.
