ABSTRACT:
An irradiation direction control apparatus for a vehicular lamp including: a vehicle state detection device for detecting a state of a vehicle; a drive device for directing irradiation light of a lamp toward a desired direction; and a compensation calculation device for performing a compensation calculation to keep the irradiation light of the lamp to a predetermined direction in accordance with a signal from the vehicle state detection device and sending a compensation signal to the drive device, whereby at the time of lighting the lamp or during lighting of the lamp, the compensation calculation device performs the compensation calculation to keep the irradiation light of the lamp to the predetermined direction in accordance with the signal from the vehicle state detection device and sends the compensation signal based on a calculation result to the drive device to drive the lamp or components thereof, whereas at the time of deactivating the lamp or during deactivation of the lamp and with a power source of the vehicle in operation or during running of the vehicle, the compensation calculation device performs only the compensation calculation to keep the irradiation light of the lamp to the predetermined direction in accordance with the signal from the vehicle state detection device and does not send the compensation signal to the drive device.
