Abstract: PURPOSE: A circuit for driving a light emitting diode signal lamp is provided to offer a stable optical output by controlling a driving current of an LED about a variety of temperature through a thermistor. CONSTITUTION: A resistance value of a thermistor(4) is varied according to a variety of an external temperature. Namely, when the external temperature is increased, the resistance value of the thermistor(4) is decreased, and the base voltage of a power transistor(T2) is increased. When the external temperature is decreased, the resistance value of the thermistor(4) is increased, and the base voltage of the power transistor(T2) is decreased. For this reason, the luminous intensity of the LED is sustained regularly.
