本発明は、上述のごとき技術的背景にもとづいてなされ
たもので、以下、図面を参照しながら説明する。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.However, in order to use solar energy most effectively,
It is the use of sunlight energy as it is as light energy without converting it into other forms of energy such as thermal energy or electrical energy. This kind of view,
Based on this point, the present applicant focuses sunlight using a lens or the like, introduces it into a light guide cable, transmits it through the light guide Kelp to any desired location, and at that location, the light guide cable and the light guide cable. Various proposals have already been made regarding emitting light to provide illumination. Therefore, when trying to use solar energy for lighting as described above,
If the light propagated within the optical conductor cable is diverted from the optical conductive cable, its utility value will be extremely high, but such a device has not yet been proposed. was developed based on the above-mentioned technical background, and will be explained below with reference to the drawings.

しても使用可能である。FIG. 1 is a schematic sectional view for explaining one embodiment of the optical branching mechanism according to the present invention, and FIG. 2 is a view seen from the direction of the line ■-■ in FIG. 1, where 1 is a light guide. A rod is shown, and sunlight focused by a lens system (not shown) is introduced into the light guide rod 1, and the sunlight passes through the light guide rod while repeatedly reflecting on the wall surface of the light guide rod 1. It's being propagated. The invention can thus be applied within a light guide rod or in a light guide pipe (for the example of a light guide pipe, the third
This device branches out a part of the light that propagates through the outer peripheral wall of the light guide (see figure) and extracts it. Specifically, as shown in the figure, A hole 2 extending in the radial direction of the light guide rod or light guide pipe is provided, and a branching light guide 3 that can be inserted into and removed from the hole 2 is provided, and the tip end 3' of the branching light guide 3 is inserted into the hole 2. The branching light guide 3 is tilted opposite to a plane perpendicular to the axis, and the tilted surface is made into a reflective mirror surface.In this way, the light L' that hits the tilted surface 3' is reflected by the tilted surface. The light L'' that is reflected by the surface and branched into the branching light guide 3 and passes through areas other than the inclined surface passes through the branching light guide and propagates within the light guide rod 1 as it is. The amount of branched light can be adjusted by the insertion depth of the branching light guide 3, and in the state shown in the figure, the amount of branching is the maximum, and as it is inserted deeper, the amount of branching decreases, and at the position of the chain line shown in the figure, it is approximately 0. becomes.In addition,
In this case, if the branching light guide 3 is turned upside down and the light is isometrically propagated inside the light guide rod 1 from the direction of the LO, the light LO will be transmitted to the inclined surface 3'. Since the light beam is reflected in the direction of L6 and emitted to the outside of the light guide 1, the light branching mechanism according to the above embodiment can also be used as a 1-light:radiator.
