[Background technology]

Conventionally, lighting fixtures installed in gymnasiums and stages have been difficult to maintain, such as replacing lamps, because they are located at high places. Therefore, for ease of maintenance, an elevating lighting fixture has been proposed in which the lighting fixture can be moved up and down.

However, since the irradiation direction of the lamp is fixed, the light distribution is fixed and there is a problem in that it is not possible to obtain an appropriate light distribution according to the purpose of use, such as sports events such as gymnasiums, event contents, etc.

Providing a rotation drive device for the lamp eliminates this problem. However, with elevating type lighting equipment, the rotational drive transmission system must be disconnected when the lamp is lowered, and general transmission systems such as belts and gears cannot be used. Further, if a separate drive source such as a clutch or solenoid is used for disconnection, the structure becomes complicated.
