A light source such as a lamp is used as the light source 1 and is located on one side above the reflection plate 2. The reflection plate 2 is made of a highly reflective material such as aluminum, is fixed to the rotation mechanism 5 by bolts or the like, and is opened at the center thereof so as to freely pass through the axis of the rotation mechanism 5.
As the rotation mechanism 5, a motor or the like is used, and the reflection plate 2 is used.
, The axis of which passes through the center opening of the reflector plate 2, and the tip of the axis projects to a predetermined position above the light source 1. The flat body 3 is disposed on the tip of the shaft by a screw or the like.

The flat plate 3 is formed integrally with a transparent thin material having various colors or patterns, and a reflecting element 4 made of a highly reflective material is vertically arranged around the flat element. The reflection element 4 is formed of, for example, a reflective material such as an aluminum vacuum deposited film. In order to increase the reflection effect and increase the change of the color light, the reflection element 4 is arranged in a polygonal shape, and the color light transmitted through the flat plate 3 is highly reflective. By virtue of the side reflection, more vivid color light can be produced.

The decorative lighting fixture A of the present invention described above will be described below.
The state of use will be described.

The power supply is started to rotate the shaft 6 of the rotating mechanism 5. The reflection plate 2 and the light source 1 are not rotated since they are fixed to the rotation mechanism 5, and therefore, the flat plate 3 and the reflection element 4 are not rotated.
Rotates relative to the light source 1. Therefore, the color or pattern on the flat body 3 facing the light source 1 changes periodically. At this time, the light radiated from the light source 1 irradiates the flat plate 3 directly or through the reflection of the reflecting plate 2, and the flat plate 3 is a transparent thin plate having each color or pattern. Represents the color or pattern on the flat plate 3. Further, since the light source 1 and the flat plate 3 rotate relatively, the light transmitted through the flat plate 3 changes periodically. Further, the light emitted from the decorative lighting fixture A has various color light changing patterns due to the reflection of the reflection element 4, and when such a color light is irradiated on a wall, a ceiling, or an object. Then, the change pattern of the color light is reflected on the surface of the irradiated object.

Next, another embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of this embodiment is the same as that of the above-described embodiment, the description of the same components will be omitted.

As shown in FIG. 3, the decorative lighting fixture A of this embodiment is arranged in the shade 9 by fixing the rotating mechanism 5 to the bottom of the shade 9 with bolts or the like. Further, a semi-transparent mask 7 is provided in an opening above the shade 9. Since the translucent mask 7 is provided in the upper opening of the shade 9, the light emitted from the light source 1 passes through the flat plate 3, and changes the color light to the mask 7 via the reflection of the reflection element 4. Reflect the pattern. The decorative lighting fixture having such a configuration is suitable for being placed on a desk or the like as a decoration.

Further, as shown in FIG. 4, the decorative lighting fixture A described above is arranged laterally and is supported by a support base. In addition, a honeycomb louver 8 is used instead of the mask 7,
