であつた。Prior Art The present applicant has previously proposed that sunlight or artificial light is focused by a lens or the like, introduced into a light guide, and transmitted through the light guide to any desired location for illumination or other uses. Various proposals were made. In this case, if the light energy propagating within the light guide can be branched and extracted from the light guide during its propagation, the efficiency of use of light energy can be further improved. There was no such optical branching means, which was extremely inconvenient.

用に供される。Configuration FIG. 1 is a front view for explaining an embodiment of the optical branching device according to the present invention, and FIG. 2 is a sectional view.
In the figure, reference numeral 1 denotes a first light guide rod. The light guide rod 1 has a through hole in the radial direction, and a second light guide rod 2 and a third light guide rod are inserted into the through hole. 3 is inserted, and the second light guide rod 2 is fixed with optical glue or the like. The end of the second light guide rod 2 in the penetration hole is formed into an inclined surface 2a with respect to the axial direction of the first light guide rod, and the third light guide rod 3 is formed at an inclined surface 2a with respect to the axial direction of the first light guide rod. 2
It has an inclined surface 3a opposite to said inclined surface 2a. Further, the third light guide rod 3 is fitted into the through hole so as to be able to move forward and backward, and a groove 3b is provided at the upper end along the axial direction of the light guide rod. The inclined surface 2a of the second light guide rod 2 and the inclined surface 3a of the third light guide rod 3
Optical oil is injected into the gap d between the third light guide rod 3, and when moving the third light guide rod 3 back and forth, the air in the gap is exhausted or air is introduced into the gap, and the third light guide rod It facilitates the advancement and retreat of After injecting optical oil into the gap d in this way,
When the third light guide rod 3 is pushed forward, the gap d narrows and the level of optical oil increases,
On the other hand, when it retracts, the gap d becomes wider and the level of optical oil decreases. Therefore, the light L propagated in the direction of arrow A within the first light guide rod 1 is transmitted to the inclined surface 2a of the second light guide rod 2 in the part where the optical oil is not contained in the gap. Therefore, it is reflected and travels in the direction of arrow B, and in the area where optical oil is contained, it travels in the direction of arrow C. At this time, the amount of light traveling in the direction of arrow B is adjusted by the level of optical oil in the gap. This adjustment can be made by adjusting the insertion depth of the third light guide rod 3. 4 is a fourth light guide rod fixed to the outer peripheral surface of the light guide rod 1 so as to cover the fitting portion of the second light guide rod 2, or formed integrally with the second light guide rod; The light branched in the direction of arrow B as described above is taken out through the fourth light guide rod 4 and transmitted to any desired location through a light guide cable (not shown) connected to the fourth light guide rod 4. and used for lighting and other purposes.
