The tilt motor driver 18 receiving vertical rotation information from the controller 11 receives a current vertical value detected by the tilt sensor 16 through the tilt motor unit 40 to vertically rotate the current lamp 50. By recognizing the angle and driving the tilt motor unit 40 by the rotation angle corresponding to the vertical rotation information, the corresponding lamp 50 rotates vertically by the desired irradiation angle of the console device.

In addition, the fan motor drive unit 19 that receives the horizontal rotation information from the control unit 11 also receives the current horizontal value detected by the fan sensor 17 through the fan motor unit 30 of the current lamp 50. By recognizing the horizontal rotation angle, and driving the fan motor unit 30 by the rotation angle corresponding to the horizontal rotation information, the corresponding lamp 50 is rotated horizontally by the desired irradiation angle of the console device.
