The invention discloses a logic protection emitter coupled three-filtering type voice control automobile lamp power-off protection system which is mainly composed of an integrated chip AL, a timer, a control circuit, a photo resistor RL, an overvoltage protection circuit, a voice control system and the like. A three-filtering amplification circuit and a logic protection emitter coupled amplification circuit are further arranged. The logic protection emitter coupled three-filtering type voice control automobile lamp power-off protection system can well filter out clutter in the circuits, so that the accuracy of the product is greatly improved and the application range of the product is greatly enlarged; a power source can be cut off automatically when a driver forgets to turn off an automobile lamp, and therefore the phenomenon that electricity of a vehicle-mounted storage battery is exhausted can be effectively eradicated, and the service life of an automobile bulb and the service life of the storage battery are prolonged to the maximum.
