Abstract

PURPOSE:To make it possible to illuminate a statue of a religious object with a natural light by providing plural sets of ring-form lenses of coaxial glass blocks facing in a specific direction, and dispersing light passages which consist of plural glass blocks. CONSTITUTION:A lens 3 consists of a central circular lens 31, ring-form coaxial lenses 32-34 surrounding the central lens 31 in a circular form, and the like, forming a ring-form lens set as a whole. The focuses of the lenses are designed to coincide to the input end 41 of a photoconductor 4, and the circumferential surfaces a-c of the lenses are formed as conical surfaces with sloped surfaces coincident to the refraction light passage in the lenses. On the other hand, numerous hexagonal glass blocks are combined with lead plates or the like to make light emission holding plates 5 and 6, which transmit the scattered light input from a zenith window and ring-form windows to the downside, while holding focusing light passages. As a result, a statue of a religious object can be illuminated with a natural light, the light is natural compared with an artificial light, and in a specific time, the luminous light can be emitted strongly from the statue itself.

Description

[Detailed description of the invention] Presenting upper momme beans ■ Beans each other The present invention relates to an illumination device for an image that is an object of worship.

蓑】U Sou 4 For buildings that are the center of belief in religions.

The target statue is enshrined there. The place where they are enshrined is usually in a deep room or in the center of a building. There is no natural light and lighting is required, so candles, light bulbs, etc. are used. Care must be taken to ensure that the lighting does not spoil the atmosphere.

Even when using light bulbs, those with high brightness are avoided.

Therefore, statues had to be placed in dimly lit places even during the day, and additional costs were required for lighting.

By taking in sunlight, the present invention illuminates the image that is the object of the faith with natural light, and at the specified date and time of the faith, the image itself irradiates sunlight. The purpose is to enable children to practice their faith amidst the blessings of nature.

I-Ikuni The present invention includes a plurality of ring-shaped lenses made of concentric glass blocks arranged in a predetermined direction, a light guide whose end is arranged near the focal point of each set of lenses, It consists of a condensing optical path in which the light guide is arranged surrounding a central support member, a diffusing optical path made up of a plurality of glass blocks supporting the optical path as a center, and an image of an object of worship, and the image is arranged in the diffusing optical path. The image is characterized in that it is illuminated by an optical path and that a condensing optical path is guided to an appropriate position of the image.

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. If configured as a circle, for example, the diameter is 5 m and the height is 40 m.
However, the shape, size, etc. are not particularly limited, and any shape or size may be used. 1 is a lighting window at the zenith, and 2 is an annular window provided concentrically therewith. Reference numeral 3 denotes a lens fixed to the light collecting tower so as to focus on the input end of the light guide 4 at a specific point in time which will be described later.

As shown in FIG. 3, the lens 3 includes a circular lens 31 in the center and a ring-shaped lens 3 surrounding the central circular lens 31.
It consists of 2 to 34 lenses, forming a ring-shaped lens as a whole. The focal point position of each lens is at the input end 41 of the light guide 4.
It is designed to meet the Also, the peripheral surface a-
C is formed as a conical surface having an inclined surface that coincides 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 attachment of each lens assembly is selected such that sunlight is focused on one 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 guide 4 corresponding to each set of lenses is constructed using a metal wire 7 made of, for example, a titanium alloy as a center support member.
They are compiled into a book to create a condensing optical path. Reference numeral 51 denotes a hexagonal glass block, and a number of these blocks are combined with lead plates or the like to form a translucent support plate 5 as shown in FIG. 1 to support the light condensing optical path described above. At the same time, the glass block transmits the scattered light entering from the zenith window and the annular window downward, and further transmits the incident light downward through the second transparent support plate 6 configured 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 an image that is an object of worship,
It is enshrined on pedestal 8. A diffused light path opens above the image 7. The light guide 4 is suitably guided into the machine and separated into openings, for example into the eye 71 and palm 72 of the image.

As is clear from the above configuration, the scattered light incident from the light collection tower illuminates the image from above through the diffused optical path. Also,
At the specific dates and times mentioned in (1) to (W) above, sunlight focused by a specific set of lenses is intensely irradiated from appropriate positions of the image, such as the eyes and palms, as several rays of light. Ru.

Effects The present invention is more natural than artificial light because the image that is the object of worship can be illuminated with natural light as described above. Also, at certain times, the statue itself emits intense light, giving gratitude and peace to those who believe in it. Furthermore, since a ring-shaped lens is used as a lens for condensing light, the amount of expensive optical glass can be reduced and the weight can be reduced.
