発光素子と直列に接続されてなる電気光−換器。An electro-optical conversion circuit that operates a circuit with a light emitting element whose relative optical output and forward voltage at the same forward current value are inversely proportional to temperature, and whose forward current and forward voltage are directly proportional, at a light output within a permissible range at a predetermined load. In order to compensate for the decrease in relative light output and forward voltage of the light emitting element due to temperature rise, an increased forward current is rectified for the light emitting element to compensate for the difference between the predetermined voltage and the decreased forward voltage of the light emitting element. An electro-optic converter comprising: a fixed resistor having a resistance value that generates an increased voltage that balances the voltage increase that is to be generated; connected in series with the light emitting element.
