装置。In an elevating lighting device in which a lighting fixture is suspended by a wire from a fixed part and the lighting fixture is raised and lowered by winding up or unwinding the wire using a motor, an appropriate pulley placed in the fixed part and on which the wire is hung is provided. This pulley is made movable and is biased in the direction opposite to the tension of the wire by an elastic body such as a tension coil spring, and raised to a position in the direction of tension and a position in the direction opposite to the tension by the elastic body. The movement of the pulley is detected by these switches, and when upward force is applied to the lighting equipment, the pulley is moved upward, the lift switch is turned on, and the motor is turned on in the wire winding direction. An elevating lighting device that is driven in the wire rewinding direction by moving a pulley downward when a downward force is applied to the lighting equipment, turning on a lowering switch, and driving a motor in the wire rewinding direction.
