As shown in FIG. 3, the light source head 5 is recessed from the cylindrical portion 5 e surrounding the disk 6 with straight strip-shaped portions 5 f toward both sides of the trapezoid 14 having a cross section.

  The display stand 2, the light source head 5, and the column 14 integrally form a casing. The light source head 5 has a lid member 5c just fitted into the fitting portion 5d. However, the upper portion of the column 14 and the light source head 5 may be fixed to be tiltable, and the shaft 7 may be tilted.

  The back surface of the display stand 2 is a back cover 2d that is detachably fitted to the display stand 2.

(Function)
The exhibit 3 is placed or fixed on the surface 2 a of the display stand 2.

  When the push button 12a is pressed to input, the internal lighting circuit and control circuit are energized. The power supply from the lighting circuit is transmitted to the slip ring 6e via the brush 13, and is supplied to the light source 4 through the wiring (not shown) from the slip ring 6e. At the same time, the motor 8 is energized by power supply from the control circuit, the pulley 9 rotates, and the disk 6 rotates around the shaft 7 via the round belt 11.

  Thus, the exhibit 3 (see FIG. 1) on the display stand 2 is irradiated with light from the light source 4 that rotates. If the exhibit 3 is a piece of jewelry or cut glass, the light source 4 will continuously irradiate the jewelry and cut glass from all angles, so that even if the viewer stays in one place, the exhibit Shines in the blink of an eye. The viewer sees the exhibit 3 from above, while the light from the light source 4 irradiates the exhibit 3 from above, so that the exhibit 3 can be seen well. Due to the light shielding part 5a, the light from the light source 4 does not enter the eyes of the person viewing the exhibit 3, so that the exhibit 3 is easy to see.

  In the case of display replacement, if the display lighting device is moved together with the exhibits, the display position can be easily changed because the related position does not change.
