Description

[Detailed Description of the Invention] [Industrial Application Field] In recent years, buildings such as residential complexes such as condominiums have been modified from uniform designs to designs that blend in with the surrounding area. It looks like this. The present invention further advances the above-mentioned trend, and emits light by arranging light-emitting parts in a dispersed manner on the outer surface of a building such as a residential apartment complex, thereby making the entire building stand out or adding various features to the outer surface of the building. This article relates to a lighting method for a building and its device for creating a lighting effect in a building, such as making light Mi4 appear. [Prior Art] Conventional lighting methods and devices for buildings generally involve lighting common passageways such as hallways and elevator halls with electric lights, fluorescent lights, or the like.

Such common passages were usually located at the back of buildings, not facing the outside, such as roads, and were only intended to provide lighting for traffic. In addition, in order to consider the lighting effect of the entire building, for example, electric lighting equipment such as hooded electric lights and fluorescent lights is installed on the balcony of each condominium unit, and this is used to improve the lighting effect inside and outside the building. It is known that the entire building can be seen at night by being illuminated.

[Problems to be Solved by the Invention] However, in the above-mentioned lighting methods and devices using electric lighting equipment, the light bulbs inside the lighting equipment have a limited lifespan, so there is a need for replacement and inspection. However, when installing electric lighting equipment on a balcony, etc., it must be installed in a place where it will not interfere with daily life, such as removing the clothesline or hanging futons to dry, so it is inevitable to install it in a corner of the balcony. Even within reach,
This had the disadvantage of requiring a stepladder, which required time and effort to replace and inspect, resulting in high costs. In particular, as buildings tend to become taller in recent years, replacement and inspection work must be performed at heights, which is dangerous and increases costs even further. In addition, it is extremely dangerous if light bulbs or appliances are accidentally dropped during replacement or inspection work, so if the work is done at a high place, protective nets must be put up, which requires more effort and costs. Ta. These results
Even if some of the light bulbs were defective, they tended to be left unreplaced without being replaced, which had the disadvantage of reducing the performance effect. Furthermore, since it is impossible to replace or inspect light bulbs from outside, it is difficult to do so through the interior of each residence, which tends to be avoided due to privacy concerns, making it difficult to adopt this system. The present invention has been made in view of the above circumstances, and has an objective of making it possible to easily replace and inspect the light source, and to provide a good lighting effect for the entire building. The purpose is to

, [! Means for Solving the Problem] In order to achieve the above object, the method for illuminating a building according to the present invention takes in light from a light source unit installed in the building, and transmits the light to the building. The invention is characterized in that it is guided to each of a plurality of locations on the outside of the building via an optical fiber bundle that passes through the inside of the object, and emits light inside and outside of the building. In order to achieve the above-mentioned purpose, the lighting device for a building according to the present invention includes a light source unit, which is passed through the inside of the building, and is converged at one end and divided at the other end. an optical fiber bundle, and a light emitting unit disposed at a plurality of locations on the outer surface of the building; The divided ends of the light emitting parts are placed on each of the multiple light emitting parts. A halogen lamp can be used as the light source for the light source unit. Further, the light source may be installed anywhere within the building, for example, in a bomb room or a machine room. As the optical fiber bundle, a plurality of known optical fibers can be bundled and used, or one end can be bundled and the other end can be divided and the divided side can be used as a small bundle. Note that quartz-based optical fibers and plastic-based optical fibers can be used as well-known optical fibers, and although quartz-based optical fibers are superior in terms of light transmission, they are easy to break, have poor workability, and are expensive, and plastic-based optical fibers are It is preferable to use optical fiber. However, the number of optical fibers is not particularly limited. When using a plastic optical fiber, it is preferable to use one with a diameter of about 0.25 to 3.0 mm. In the case of the present invention, since the distance is long, if it is less than 1.0 am, it will be easily affected by the length and the amount of light transmitted will be disadvantageous. On the other hand, if it exceeds 3.0 am, the rigidity of the optical fiber itself will become strong. This is because it becomes difficult to handle. The light emitting part may be the end face of an optical fiber itself, which is obtained by processing the end face of a small bundle of divided optical fibers into a planar shape, but it is preferable that it is a light diffusing means provided at the tip of the small bundle of optical fibers. ．． Furthermore, emitting light outside the building means
In addition to the case where the light is emitted towards the outside of the building, it also includes the case where the light is emitted towards the building itself. The present invention can be applied to buildings such as residential housing complexes such as condominiums and office buildings, and when applied to residential housing complexes, a part of the optical fiber bundle is divided and the divided small bundles are One end side may be opened into the living room, and the illumination light inside the living room may be used as part of the light source. In addition, a part of the optical fiber bundle that is wired through the living room is divided, and the divided small bundles are arranged in a plane and exposed inside the living room, so that the light leaking from the side wall of the optical fiber illuminates the living room. Also good. At this time, by scratching or bending the side wall surface of the optical fiber exposed inside the living room, a diffused reflection portion may be actively attached to adjust the amount of illumination light into the living room.

[Function] According to the method and apparatus for lighting a building according to the present invention, the light source unit and the light emitting part are separated, and the light from the light source unit is transmitted to the building by an optical fiber bundle passing through the inside of the building. The light is guided to a plurality of light emitting parts on the exterior side of the building, and the light is emitted from the inside and outside of the building on the exterior side of the building, making it possible to create a dramatic effect such as making the entire building stand out.
