【発明の詳細な説明】
本発明は、光導体内を伝搬されてくる光を効果的に拡散
させて照明に供し得るようにした照明器具に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device that can effectively diffuse light propagated within a light guide to provide 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向で活発に研究開発が行われてい
る。BACKGROUND ART Recently, we have entered an era of energy conservation, and research and development is being actively conducted in various directions regarding the effective use of solar energy.
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１熱エネルギー等に変換することなく、
そのまま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、最も効率的である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等に導いている。When using solar energy, solar energy is not converted 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 that it is the most efficient method. Conventionally, solar energy collected outdoors is guided through a light pipe to a place that requires illumination, such as indoors.
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、部屋全体を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 illuminating an entire room.
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で室内を照明するに際
し、光導体から放出される光を効果的に拡散して室内全
体を効果的に照明するようにしたものである。The present invention was made in view of the above-mentioned circumstances, and
When illuminating a room with light propagated through a light guide, the light emitted from the light guide is effectively diffused to effectively illuminate the entire room.

明による照明器具はＹ−Ｙ軸に関して軸対称であるので
、図には、Ｙ−Ｙ軸の右半分のみを示しである。The figure is a side sectional view of the lighting fixture according to the present invention, but since the lighting fixture according to the present invention is axially symmetrical with respect to the Y-Y axis, only the right half of the Y-Y axis is shown in the figure.

好ましくは、該密封容器内に窒素ガス等が封入され、該
密封容器内に塵埃等が入らないように構成されている。In the figure, 1 is a light guide, 2 is a guide body receiving part, 3 is a transparent body for sealing the guide body receiving part, and 4 is a guide body receiving part 2
0 is a reflective mirror surface provided around the periphery, 5 is a translucent rest provided adjacent to the periphery of the reflective mirror surface 4, and 6 is a transparent portion provided adjacent to the periphery of the semitransparent body. In the body part, these guide body receiving part or transparent body part 6 constitute a sealed container,
Preferably, nitrogen gas or the like is sealed in the sealed container to prevent dust or the like from entering the sealed container.

。In addition, inside the sealed container, there is a light-transmitting part (transparent or hollow) 7.
．． Concave lens8. A reflecting mirror plate 9 is provided, and the light emitted from the center of the light guide 1 is transmitted through the light transmitting portion 1 and the concave lens 8V? c Therefore, as shown by arrow A, the light that is focused and diffused in a spot and is emitted from the middle part of the light guide 1 is:
As shown by the arrow B, the light source with high brightness is reflected and diffused by the reflector plates 9 and 4 while maintaining its beauty, and furthermore, the light emitted from the periphery of the light guide 1 is reflected and diffused by the reflector plate 9 and the semi-transparent plate. 5, the light is reflected and diffused as soft light, that is, light that does not hit the eyes, as shown by arrows C and C'.
なお、透光部７及び反射鏡板９は、反射鏡板９の影にな
るす領域を利用して透明板６に取り付けることができ、
このようにすれば、反射鏡板９の影を生じるようなこと
はない。Note that the light transmitting portion 7 and the reflective mirror plate 9 can be attached to the transparent plate 6 by using the area that will be in the shadow of the reflective mirror plate 9.
In this way, there will be no shadow from the reflecting mirror plate 9.
以上の説明から明らかなように、本発明によれば、光導
体から放出される光を効率よく掛数することができ、従
って、部屋全体を効率よく照明することかできる。As is clear from the above description, according to the present invention, the light emitted from the light guide can be efficiently multiplied, and therefore the entire room can be efficiently illuminated.
