Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lighting device for a Buddhist statue that is an object of worship.

BACKGROUND TECHNOLOGY Buildings that are the center of faith in religions, etc.
The target Buddha statue is enshrined here. The place where it is usually enshrined is in the back room or in the center of the building. There is no natural light and lighting is required, so candles, light bulbs, etc. are used.
In order to ensure that the lighting does not spoil the atmosphere, even when light bulbs are used, high brightness lights are avoided.

Therefore, Buddhist statues were placed in dimly lit areas even during the day, and additional costs were required for lighting.

Problems to be Solved by the Invention The present invention illuminates a Buddhist statue, which is the object of a religious belief, with natural light by taking in sunlight, and at the same time, at a specified date and time in that religious belief, sunlight is emitted from the Buddhist statue itself. The purpose of this project is to enable irradiation so that people can practice their faith in the midst of nature's blessings.

Structure The present invention comprises a ring-shaped lens made of concentric glass blocks arranged in different predetermined directions, a light guide whose end is arranged near the focal point of the lens, and a center support member. It consists of a condensing optical path surrounding which the light guide is arranged, a diffusing optical path made up of a plurality of glass blocks supporting the optical path at the center, and a Buddhist statue that is an object of worship, and the Buddhist statue is illuminated by the diffusing optical path. In addition, the present invention is characterized in that a condensing optical path is guided to an appropriate position of the Buddha statue so that light is emitted from the Buddha statue.

Examples will be described below. FIG. 1 shows a light collecting tower as a light collecting part, which is installed at the top of a building. When configured as a circle, for example, the diameter is about 5 m and the height is about 40 m, but the shape, size, etc. are not particularly limited, and any shape,
Good size. 1 is a lighting window at the zenith, 2
is an annular window provided concentrically therewith. 3
is a lens fixed to the condenser tower so as to focus on the input end of the light guide 4 at a specific point in time, which will be described below. As shown in FIG. 3, the lens 3 is composed of a central circular lens 31 and ring-shaped lenses 32 to 34 surrounding the central circular lens 31, forming a ring-shaped lens as a whole. The focal position of each lens is designed to coincide with the input end 41 of the light guide 4. Further, the circumferential surfaces a to c of each lens are formed as conical surfaces having inclined surfaces that coincide with the refraction optical path within the lens. The apex of each conical surface may be aligned with the focal point, for example. Then, the ring-shaped lens can be assembled by simply dropping it in from the outside. For example, six such lens assemblies are used. The mounting of each lens assembly is selected such that sunlight is focused on the end face of the optical fiber at the following dates and times (1) to (7), which are religious festivals, for example.

(1)...Noon of the vernal equinox, (2)...noon of the autumnal equinox, (3)…The morning of the winter solstice, (4)...Morning of the summer solstice, (5)...The morning of the founder's birthday, (6)...The morning of the founder's death anniversary. (7)...The morning of the current head priest's birthday.

Of these, (1) and (2) match, so they can be shared.
In such a date and time setting, six sets of lenses are required.

As shown in FIG. 4, the light guides 4 corresponding to each set of lenses are combined into one with a metal wire 7 made of, for example, a titanium alloy as a central support member to form a condensing optical path. Reference numeral 51 denotes a hexagonal glass block, which is joined together with a number of lead plates or the like to support the light-condensing optical path described above as a translucent support plate 5 as shown in FIG. At the same time, the glass block transmits the scattered light entering from the zenith window and the annular window downwardly, and transmits the incident light further downwardly through the second light-transmitting support plate 6 constructed in the same manner. These translucent support plates form a diffused optical path. By making the inner surface of the light collection tower a reflective surface, it is possible to improve the collection and transmission efficiency of scattered light. Note that the glass block may be appropriately colored.

The light thus transmitted is used as illumination light as shown in FIG. 7 is a Buddhist statue that is an object of worship, and is placed on a pedestal 8. Buddha statue 7
A diffused light path opens at the top. The light guide 4 is suitably guided into the image and separated into, for example, an eye 71 of the image.
and opens the palm 72.

As is clear from the above configuration, the scattered light incident from the condensing tower illuminates the Buddha statue from above through the diffused light path. In addition, at the specific dates and times mentioned in (1) to (7) above, the sunlight concentrated by a specific set of lenses from the appropriate position of the Buddha statue, such as the eyes and palms, becomes intense as several rays of light. irradiated.

Effects As described above, the present invention can illuminate the Buddhist statue, which is the object of worship, with natural light, which is more natural than artificial light. Also, at certain times, the Buddha statue itself emits intense light, which can give gratitude and peace to the believers. moreover,
Since a ring-shaped lens is used as a lens for condensing light, there is an effect that less expensive optical glass is required and the weight can be reduced.
