JP2511941Y2 - Lighting device that projects rainbow colors - Google Patents

Description

TECHNICAL FIELD The present invention relates to an illuminating device in which projection light is changed into a rainbow color by using a prism ball formed in a spherical polyhedron.

2. Description of the Related Art The use of variously colored light for illumination is well known from, for example, mirror balls. In addition, for lighting equipment using a prism as a light transmitting body, for example, Japanese Utility Model Laid-Open No. 61-100813,
There are gazettes such as No. 53815 and No. 9706, as well as No. 63-118106.

Problems to be Solved by the Invention A conventionally known mirror ball uses colored light as a light source itself, causes the ball to have a colored brightness by reflection, and illuminates with reflected light. Therefore, in order to obtain multiple colors, it is necessary to use a large number of light sources and to use a rotating colored plate like a spotlight. On the other hand, the latter uses a prism plate as a light-transmitting body that shades the light source, so it is not an illumination that dynamically changes the color of light like the former, and its prism effect is crispy. It is not much different from glass, and its use is limited only when illuminating the room with static light.

From the above, it is an issue to develop a lighting device that projects a large number of rainbow light beams with a single light source onto, for example, a wall or ceiling in a room, and the light projection is dynamically changed. Was there.

Means for Solving the Problems In order to solve the above problems, the present invention rotatably includes a prism ball formed in a polyhedron using a translucent substance having a prismatic property such as glass, and It is an object of the present invention to provide an illuminating device for projecting rainbow colors, which is characterized in that it is configured so as to be changed into a large number of rainbow colors by irradiating light from a light source.

Function The present invention transmits the light from the light source to the prismatic balls of the polyhedron, so the light is dispersed inside the ball and the emitted light is projected as rainbow-colored colored light which is dispersed in each of the multiple directions. . Also, as the prism ball rotates, the rainbow-colored light beam moves by changing the projection angle, so one light source,
Despite being a single light-transmitting body, it dynamically emits multi-colored light projections.

The present invention solves the above-mentioned conventional problems by projecting light by using the polygonal prism action as described above.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a prism ball 1 obtained by cutting a spherical glass into a polyhedron.

The light source 2 for projecting light onto the prism ball 1 uses the sun as the light source 2 in the case of the embodiment I shown in FIG.
Then, the light is projected onto the prism ball 1 which is rotatably suspended by the suspension cord 6 from the tip of the support column 5 which is integrally erected on the rotating table 4.

Example II shown in FIG. 3 is a case of projecting an artificial light ray on the prism ball 1, and changes it into a parallel light ray through a lens 8 in a cylindrical body 7 having a light source 2 for the artificial light ray. In the same manner as in the above case, light is projected through the reflecting plate 3 to the prism ball 1 installed using the rotating table 4, the supporting column 5, and the hanging string 6.

Needless to say, in implementing the present invention, the installation structure of the prism ball 1 is not limited to the illustrated mode. It is also optional to install a plurality of prism balls 1 in the same space.

The illuminating device configured as described above is placed, for example, on a table as an interior of light, or installed in a room to project a rainbow-colored light beam moving on a wall or a ceiling in a polygonal shape and dynamically. Alternatively, it is used as lighting suitable for a dynamic atmosphere.

Effects of the Invention According to the present invention configured as described above and used as described above, despite the simple structure,
Extremely dynamic and aesthetically pleasing multicolored, it can provide multi-faceted lighting, and can be used as a home interior lighting or playground equipment, or as a large-scale business like a mirror ball. It can also be used for other purposes, and has a lot of practical effects.
