DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monument installed at a place where people rest, and more particularly, to a monument having a prism to provide an aesthetic appearance by utilizing light decomposition and refraction. It is about.

[0002]

2. Description of the Related Art Hitherto, as a monument using light, there has been known a monument which irradiates an artificial light source from various directions in the dark. Conventionally, as this type of monument, a monument provided with a lighting device provided with a cover that acts like a filter in order to change the color of light or the like is known.

[0003]

However, the above-mentioned conventional monument is constructed so as to exhibit an aesthetic appearance mainly in the dark, and can hardly expect the effect when it is installed outdoors such as a park in the daytime. Was. In addition, in order to produce a color or a pattern mainly intended for light, a filter that suppresses transmission of light of a specific wavelength and acts like a filter is used, and there are many limited patterns. . Further, in the case of a huge artificial light source, the power consumed is large, so that a large cost burden is required for maintenance.

[0004] The present invention has been made by focusing on the problems existing in the prior art as described above. It is an object of the present invention to provide a monument that can form a variety of light patterns by effectively utilizing natural light and that has a low maintenance cost.

[0005]

In order to achieve the above object, a monument according to the present invention comprises a prism for decomposing, refracting and transmitting light.

According to a second aspect of the invention, in the monument according to the first aspect, the prism is a polyhedron. According to a third aspect of the present invention, in the monument according to the first or second aspect, the prism has a concave portion surrounded by a plurality of surfaces.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. (First Embodiment) As shown in FIG. 1, a monument 1 has two struts 3 erected at an angle of 60 ° from the ground 2 at an abutment point 4 in the air. Along the side surface of the opposing support column 3, an internal support column 5 formed substantially in an arch shape is attached. Further, this monument 1 has a prism 6 for decomposing, refracting and transmitting light fixed to the uppermost part of the internal support 5, and an abutment point 4.
Two artificial light sources 7 are suspended below the prism 6 so as to face the prism 6. This monument is mainly installed outdoors, and is installed at a place where a sufficient amount of sunlight is irradiated, such as at a place where many people relax or gather, such as an entrance to a park or a station.

[0010] The prism is a polyhedron molded from a material that dissociates, refracts, and transmits light, and is capable of dissolving, refracting, and transmitting irradiated light in a complicated manner. As a material for forming the prism, a transparent synthetic resin such as acryl, glass, or the like may be used, but crystal glass is preferably used because of its high refractive index and high transparency. The prism may be colored to such an extent that light transmission is not hindered, but is preferably colorless and transparent.

Examples of the shape of the prism include various types of polyhedrons and polyhedrons having a concave portion surrounded by a plurality of surfaces, such as sunlight radiated from different directions depending on the season or time, or artificial light from an artificial light source. Are decomposed and refracted in various directions. An example of such a polyhedron is 4
Examples include a polyhedron such as a pyramid, an octagonal pyramid, a hexahedron, and a hexahedron, and a diamond-like polyhedron is also possible. Further, as shown in FIG.
As shown in FIG. 2B, the prism 6 having a curved surface such as a cone and a non-polyhedral prism 6 having a polyhedron-shaped uneven portion 8 is formed on the surface of a polyhedron which is a quadrangular pyramid.
It is also possible to form a more complicated shape such as a shape with the addition of.

The prism 6 having a concave portion surrounded by a plurality of surfaces has a concave portion 9 formed from a plurality of surfaces having different angles as shown in FIGS. 3 (a) and 3 (b).
The prism 6 shown in FIG.
Each of the prisms 6 shown in FIG. The light emitted from the outside passes through the prism 6 while being decomposed and refracted, and the transmitted light passes through the concave portion 9 and is transmitted again while being decomposed and refracted when the light enters the prism 6 again. You. Therefore, this prism can further decompose, refract and transmit light more complicatedly by having the concave portion. The outer surface of the prism can have any shape, but is preferably a polyhedron because a more complicated light pattern can be formed. It is also possible to form a polyhedral uneven portion on the outer surface of the prism or on the surface on which the concave portion is formed.

The prism transmits the sunlight while resolving and refracting the sunlight. This decomposition and refraction is caused by the fact that different wavelengths of light have different indices of refraction in the prism, so that they are diverted at different angles. The transmitted light that has been decomposed, refracted, and transmitted forms a rainbow-like light pattern having various colors.

[0014] The pattern of the light greatly changes depending on the season or time. This change in the light pattern is caused by a change in the incident angle of sunlight with respect to the prism surface.
That is, when compared with sunlight in winter or morning and evening, sunlight in summer or day has a larger incident angle with respect to the ground, and moves in the east-west direction between the time the sun comes out and the time it sets. This monument can also form a calculated light pattern at a specific time and place, taking into account the sunlight irradiation angle.

The artificial light source is installed so as to maintain the position and direction in which light from the artificial light source irradiates the prism. This artificial light source preferably emits light of various wavelengths, and more preferably emits white light because light is decomposed by the prism. The artificial light source may emit a laser beam. At this time, the laser beam applied to the prism is complicatedly refracted and transmitted, forming a clear light trajectory in the dark and forming a bright light pattern. Further, the artificial light source may be a light source that radiates light radially or a beam that emits converged light. The artificial light source preferably has high illuminance in order to form a clear light pattern.

When this monument is installed outdoors, it is decomposed, refracted and transmitted through the prism in the rainy or cloudy weather or at night by artificial light from an artificial light source in the same manner as in sunlight. While forming various light patterns. In addition, when installed indoors, a pattern of light can be formed by using artificial light mainly from an artificial light source in substantially the same manner as when installed outdoors.

At the same time, a thin tube 15 having a small hole 14 formed in the peripheral wall is spirally wound. Further, this monument 1 has a prism 6 having the same shape as that of the monument of the first embodiment closely fitted to a hole 16 formed in the wall of the pipe 13, and an artificial light source 7 inside the pipe 13. Is installed. The thin tube 15 discharges water in a fountain shape through the small holes 14 while passing colored or colorless water fed from a pump buried in the ground 2 under the monument 1. Further, the released water is collected at a water inlet provided on the ground 2 under the monument 1,
