When performing the engagement/disengagement operation, the cover frame 18 may be slid from the front and rear directions with respect to the base frame 17.
Alternatively, the cover frame 18 may be forcibly fitted into the base frame 17 from below while being slightly tightened from the upper edge of the opening having a U-shaped cross section.

The base frame 17 of the appliance main body B has a washer 2 mounted with a bolt/nut 21 at approximately the center of the flat surface parallel to the wall surface W and the ceiling surface R.
The hanger band 2 is connected to the outer casing 12 of the mounting base A through the hanger band 2 and also serves as the bolt/nut 21, and has a substantially inverted U-shaped cross section.
3 is also fixedly installed on the base frame 17 of the instrument body B from below. Reference numeral 24 denotes a flexible device inserted and installed between the outer casing 12 and the base frame 17, which face each other, so that the entire appliance body B is perpendicular to the wall surface W and the ceiling surface R with respect to the mounting base A. It is designed so that it can only rotate 360 degrees, so to speak, with the axis Y-Y in the relationship as a fulcrum. In other words, the appliance main body B is in an installed state in which the cylinder core line Z-Z extends parallel to the wall surface W and the ceiling surface R as a whole as a hollow cylinder, and in this state, the axis of the flexible device 24 Around Y-Y, 360
It is designed so that only one degree of swinging motion can be performed.

While a light pattern modeling disk 55 prepared in various forms such as The base frame 17 is pivoted so that it can only rotate 360 degrees.
By being detachably locked to the base frame 17, it is formed into an assembly with the cover frame 18 that encloses the lamp case C and lens holder D, and the cylinder core line Z-Z is aligned with the wall surface W. A pair of opposing pivot screws 34 are used to connect the front of the lamp case C to the overhanging end of the hanger band 23 that integrally overhangs inward from the base frame 17. The lamp case C and the lens holder D are connected and supported, and the entire lamp case C and lens holder D are arranged along separate axes perpendicular to the axis Y-Y of the instrument body B in the limited internal space of the instrument body B. Maintaining the ability to see-saw back and forth by a certain angle θ around The fixed angle θ of the seesaw movement is set to be adjustable by advancing and retracting a presser screw 49 screwed into the plate, and the light emitted from the light source lamp 44 is shaped into a pattern corresponding to the form of the modeling disk 55. At the same time, the light is colored by the color filter 65 and/or given a refraction effect by the mirage lens 67, and then passes through the wide lens 63 or the narrow lens 69 to the wall surface W or ceiling surface R to which the mounting base A is directly fixed. A lighting equipment for performance, characterized in that it is configured to project the image in a caressing manner.
