At ice skating rinks, which are mainly used for entertainment purposes, they not only try to improve the quality of the ice on the rink, but also add various features to the rink, such as coloring the inside of the rice, and improving the quality of the ice from outside. They also put reflective materials in the water. Also, in skating rinks for sports competitions, the in-ice coloring method is used for track lines, ball game frames, center lines, etc. In addition, at indoor skating rinks, laser light is emitted from the upper space such as the ceiling,
The atmosphere of the skating rink is created using illuminations, cocktail lights, mirror balls, and other lighting.

In recent years, as various types of lighting have been developed and put into practical use, displays using laser light have been increasingly applied, and are used to display patterns on the surface of ice. On the other hand, attempts have been made to draw patterns, lines, etc. using the internal brightness of light emitted from underwater, but this is not possible with equipment that can be used for light that is close to a point light source with a small luminous flux diameter, such as laser light. There is a drawback that it is necessary to provide Moreover, it is extremely difficult to install a transmitter that can scan laser light two-dimensionally underwater, and it must be said that it is impossible in terms of equipment costs. Furthermore, in the case of laser light, there is a risk that the mouth will be directly irradiated with a light source with an output of 1 milliwatt or more, and it is also necessary to disperse the laser light over a wide range and to reduce the focusing ability.

This invention takes advantage of the fact that light passes through a convex light transmitting material placed in front of a light source with a small beam diameter, such as a laser, and is diffused by the lens effect. This ensures sufficient diffusion even if the distance from the transparent material to the ice surface is short. That is, the present invention is characterized in that a plurality of light transmitting materials each having an uneven cross section are buried in water in front of a highly condensing light source so that the groove directions of the uneven sections intersect at a desired angle. do.

以下、この発明を図面により具体的に説明する。Hereinafter, this invention will be specifically explained with reference to the drawings.

FIG. 1 shows an example of the arrangement of a light source and a light diffuser used in the present invention, with a light source that emits a laser beam 1 and a light diffuser 2 above it. ! : A lens with a wavy cross section and a semicircular shape on one side is buried under the ice 3. In such a configuration, the laser minute light source 1 enters the light diffuser 2,
Due to the convex lens effect on this surface, the beam diameter and light diffuser 2
The light spreads according to the size of the unevenness, passes through the ice 3, and forms a pattern of a diffusion region 5 on the ice surface 4. In FIG. 1, since there is only one light diffuser 2, the light source only spreads in one dimension, and shows a state in which a so-called point light source appears in the form of a single line. In addition, in the figure, 6 is an optical path after refraction, and 7 is a focal point.

Next, FIG. 2 is an explanatory diagram showing essential parts of a light emitting device showing an embodiment of the device of the present invention. In this device, two diffusers 2 are placed one on top of the other with a space between them, and the grooves are arranged so that their directions are shifted by 90°, in other words, they are perpendicular to each other. Note that 10 is a light emitting section (light source). As a result, the first light diffuser spreads the light into a linear light diffusion region 5-1, as shown in FIG. -2, planar shape (2
It appears on the ice as a planar luminescence that is diffused in a dimension (dimensional shape).

Furthermore, by gradually shifting the intersection angles of the first and second sheets, the second light diffusion region 5-2 can be transformed from a rectangular state to a diamond shape, and at each intersection of 0°, 1 It is possible to obtain a one-dimensional linear diffused light similar to that in the case of a single sheet. By increasing the number of sheets*, this pattern becomes even more complex, and it becomes possible to create various patterns in a simple manner.

In this invention, as shown in FIG. 1, the relationship between the beam diameter d of the light source and the pitch p of the unevenness is extremely important in determining the diffusion rate of the light diffusion region 5. For example, if the Fil (diameter) d of the laser beam 1 is sufficiently smaller than the pitch p, the laser beam 1 will be refracted and travel only along one optical path of the light beam in Figure 1, so it will not be diffused at all. It would end up reaching the ice without any time. Therefore, it is important to process the light diffusing body into irregularities with a pitch equal to or smaller than the diameter of a point light source such as a laser beam. In addition, as a light diffusing material, a light transmitting material (lens) having an uneven cross section such as a semicircle, a triangular waveform, or a Fresnel lens shape on one or both sides.
can be used. Figure 3 (A), (B), (C)

As described above, according to the present invention, it is extremely easy to diffuse a single beam from a point light source over a wide area, and furthermore, there is no need for any electrical control such as laser light source scanning, so it is possible to spread a single beam from a point light source over a wide area, and therefore it is possible to spread a single beam from a point light source over a wide area. You can get a lot of light.
