a and an infrared type optical remote control means composed of an optical receiver 5b, and a control light from an optical transmitter 5a in a spot illuminator similar to the conventional example which enables remote control of blinking of spot illuminator and illumination direction. The light receiving section 7 of the optical receiver 5b that receives the light to control the rotation of the instrument body 1 is provided on the lower surface of the instrument body 1. In the embodiment, the hanging pipe 20 rotated by the horizontal rotation motor 4a,
The holding means 3 includes an inverted U-shaped holding metal fitting 21 and an attachment shaft 22.
And the instrument body 1 is hung horizontally by a hanging pipe 20 which is rotated around an axis, and the instrument body 1 is vertically rotated around a mounting shaft 22 by a vertical rotation motor 4b. 1 is vertically rotatable so that the spot illumination direction can be changed three-dimensionally. Further, the light receiving portion 7 provided on the lower surface of the instrument body 1 is provided in the vicinity of the extension line of the hanging pipe 20, so that the position does not change much even when the instrument body 1 is horizontally rotated. ing. The configuration of the optical receiver 5b is the same as the conventional example,
In the embodiment, the control circuit section 8 is provided in the instrument main body 1, but it goes without saying that the control circuit section 8 may be provided in the ceiling-embedded block 6.
