Description
【発明の詳細な説明】
本発明は、光導体内を伝搬されて（る光を光源として使
用する照明方式に関し、特に、光導体内を伝搬されて（
る光を効果的に拡散されて照明に供し得るようにしたも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an illumination method using light propagated in a light pipe as a light source, and in particular to a lighting system using light propagated in a light pipe as a light source.
This allows the light to be effectively diffused and used for illumination.
近時、省エネルギ一時代を迎え、太陽光エネルギーの効
果的利用について各方面で活発に研究開発が行われてい
る。Recently, we have entered an era of energy conservation, and research and development on the effective use of solar energy is being actively conducted in various fields.
太陽光エネルギーを利用する場合、太陽光エネルギーを
電気エネルギー、熱エネルギー等に変換することなく、
そのま又光エネルギーとして室内照明等に利用すれば、
変換ロスがなく、最も効率がよいことは明らかであり、
従来、屋外で収集した太陽光エネルギーを光導体を通し
て照明を必要とする箇所例えば室内に導いて照明に供し
ている。When using solar energy, there is no need to convert solar energy into electrical energy, thermal energy, etc.
If you use it directly as light energy for indoor lighting, etc.
It is clear that there is no conversion loss and it is the most efficient.
Conventionally, solar energy collected outdoors is guided through a light guide into a location that requires illumination, such as indoors, to provide illumination.
しかし、光導体の端面から光を放出させた場合、光の広
がり角度は約４５°でスポット光源に近いものとなって
しまい、広い範囲例えば部屋全体をやわらかく照明する
には必ずしも満足のいくものではなかった。However, when light is emitted from the end face of the light guide, the spread angle of the light is approximately 45°, which is close to a spot light source, which is not necessarily satisfactory for softly illuminating a wide area, for example, an entire room. There wasn't.
本発明は、上述のごとき実情に鑑みてなされたもので、
光導体を通して伝搬されてきた光を効果的に拡散して比
較的広い範囲をやわらかい光で照明し得るようにしたも
のである。The present invention was made in view of the above-mentioned circumstances, and
The light propagated through the light guide is effectively diffused to illuminate a relatively wide area with soft light.
図は、本発明による照明方式の一実施例を説明するため
の図で、図中、１はスタンド、２は光導体、３は光導体
２の光放出端２から放出される光が直接口に入らないよ
うにするためのフードで、これらは例えば床上に配置さ
れている。The figure is a diagram for explaining one embodiment of the illumination method according to the present invention. In the figure, 1 is a stand, 2 is a light guide, and 3 is a figure in which light emitted from the light emitting end 2 of the light guide 2 is directly emitted from the mouth. These are placed on the floor, for example.
また、４は笠、５は散光体で、これらは例えば天井にω
架されている。In addition, 4 is a shade, 5 is a diffuser, and these are used for example on the ceiling.
It is suspended.
従って、今、図示のように、光導体２の光放出端２と散
光体５を対向させ、光放出部２より散光体５に向けて光
を放出すると、光放出部２より放出された光は、図中に
点線にて示すように散光体５によって散光され笠４によ
って拡散され、広い範囲にわたってやわらかい光で照明
することができ、笠４を半透明体で構成する時は、更に
広い範囲にわたって照明することができる。Therefore, as shown in the figure, when the light emitting end 2 of the light guide 2 and the light diffuser 5 are made to face each other and light is emitted from the light emitting part 2 toward the light diffuser 5, the light emitted from the light emitting part 2 is As shown by the dotted line in the figure, the light is scattered by the diffuser 5 and diffused by the shade 4, so that a wide area can be illuminated with soft light, and when the shade 4 is made of a semi-transparent body, an even wider area can be illuminated. can be illuminated throughout.
なお、図には、光導体２をスタンド１の中空部を通して
配設する例を示したが、光放出部２を部屋の壁面に直接
取り付けるようにしてもよく、また、笠４及び散光体５
も天井に限らず部屋の壁面等任意箇所に光放出端２に対
向して配設するようにしてもよく、その際、光放出端２
から放出される光軸と散光体５の中心軸とにある角度を
もたせてもよいことは容易に理解できよう。Although the figure shows an example in which the light guide 2 is placed through the hollow part of the stand 1, the light emitting part 2 may be directly attached to the wall of the room, and the light guide 2 may be installed directly on the wall of the room.
The light emitting end 2 may be disposed not only on the ceiling but also at any location such as the wall of the room, facing the light emitting end 2.
It is easy to understand that the optical axis emitted from the diffuser 5 and the central axis of the diffuser 5 may form a certain angle.
また、散光体５をくもりガラス等で形成されたグローブ
とし、その中に通常の電球等を配設するようにすること
も可能であり、このようにすると電気照明と光導体から
の光による照明を選択的に或いは同時に行うことができ
る。It is also possible to make the diffuser 5 a globe made of frosted glass or the like, and place a normal light bulb or the like inside the globe.In this way, the light from the electric light and the light from the light guide can be combined. This can be done selectively or simultaneously.
以上の説明から明らかなように１本発明によると、簡単
な構成によって、或いは、通常の電気照明器具を利用し
て、光導体から放出される光を効果的に散光、拡散し、
比較的広い範囲をやわらかい光で照明することができる
。As is clear from the above description, according to one aspect of the present invention, light emitted from a light guide can be effectively diffused and diffused by a simple construction or by using a conventional electric lighting device;
A relatively wide area can be illuminated with soft light.
