摘要： PROBLEM TO BE SOLVED: To provide a control device of the direction of irradiation of a lighting fixture capable of shortening the initializing time of a stepping motor, and suppressing degradation thereof. SOLUTION: In the control device of the direction of irradiation of the lighting fixture comprises a driving means for deflecting the direction of irradiation of the lighting fixture and a control means for performing the deflection by controlling the driving means, the control means has an initializing function for setting a stepping motor as a drive source of the drive means to the initial position. The initializing function detects the first present positional angle θ1 of the stepping motor, rotates the stepping motor at a high speed until the first present positional angle reaches the reference angle α when the first present positional angle is larger than the reference angle α, rotates the stepping motor to the butting position S at a low speed after the present positional angle reaches the reference angle α, and sets the stepping motor to the initial position I by rotating the stepping motor in the opposite direction by the predetermined steps after the butting.

摘要： PROBLEM TO BE SOLVED: To provide a lighting fixture system for vehicles capable of judging the number of abnormal luminous elements and other abnormal elements within a lamp through connection of a single line between the lamp and a judgment circuit. SOLUTION: The system is equipped with a luminous unit 20, composed of the parallel connection of a plurality of luminous elements 21; a lamp TL, which is fitted with a line breakage detection circuit 22, designed to detect line breakage of individual luminous elements; and a judgment circuit 5, linked with the line breakage detection circuit with a single signal line and designed to judge abnormality of luminous elements. The line breakage detection circuit 22 outputs an electric potential corresponding to the luminous element, from which line breakage was detected, to the signal line SL, while the judgment circuit 5 passes judgment about the abnormal luminous element in line with the electric potential from the said signal line SL. Because the number of luminous elements in which line breakage occurred and their position/arrangements within the lamp cause changes in the electric potential output to the signal line, the judgment circuit 5 can judge the number of abnormal luminous elements and their location/arrangements within the lamp.

摘要： PROBLEM TO BE SOLVED: To precisely detect a rotating direction and a rotating position of a motor by eliminating noise effect superimposed on a signal from a detecting element detecting the rotating position of the motor. SOLUTION: The lighting device for the vehicle is equipped with a driving motor 42 for a light axis deflecting means for deflecting the lighting device provided on the vehicle, detecting elements H1 to H3 outputting the signal for detecting the rotating position of the driving motor, and a motor control means 433 for controlling a rotating operation of the driving motor based on the detected rotating position. The lighting device is equipped with a means 434 which detects abnormality of the signals P1 to P3 from the detecting elements and detects the rotating position of the driving motor by correcting the abnormal signal based on the normal signal when detecting the abnormality. When the rotating position and/or rotating direction of the motor cannot be normally detected because the noise is superimposed on the signal outputted from the detecting element, the correction is performed based on the normal signal obtained around the time, and the rotating direction and the rotating position of the motor can be precisely detected.

The initialization function includes function for detecting a current positional angle of the motor and rotating motor in a bumping direction at a high speed until a reference angle is reached, when the positional angle is greater than the reference angle. The motor is rotated to a bumped position at an initial number of steps at a low speed after the reference angle is reached. The control unit controls the driving mechanism to perform a deflection of the emitting direction of a lamp. The motor is rotated in a reverse direction at a predetermined number of steps and the initial position is set after the bumped position is reached. An independent claim is also included for an emitting direction controlling method for a lamp.
