FIG. 8 is an explanatory view of a main part of the first embodiment, and FIG. 8 is a cross-sectional view of a main part of the illumination device of the first embodiment.
[0008]
(Condensing tube 10)
In this embodiment, as shown in FIGS. 4 to 7, by arranging a plurality of unit light collection tubes 10 a having substantially the same shape in the light collection tube 10, incident light SL4 passes through the glass 30 and enters the unit light collection tube 10 a. All incident light can be effectively used without reflecting it to the outside. Regarding the reflection in the Z-axis direction (lateral direction), the partition plates of the mirror body of the longitudinal reflection wings 21 and 21a formed in the light collection tube 10 are juxtaposed in a form close to concentric circles, and the first reflected light is reflected. It is curved so as to be guided in the direction of point P at the entrance of the light guide tube 41.
That is, if it demonstrates in FIG. 6, light of all angles (15 to 60 degrees in the example of FIG. 6) which inserts into the E1 range will be light guide pipes on the side surface of the condensing tube 10 and the longitudinally reflecting feathers 21 and 21a in the tube. 41 is curved toward the direction of point P near the entrance of 41. In addition, for the light to be inserted into the E2 range, the curvature of the longitudinal reflection wing 21 is in the reverse direction. Since the gaps are juxtaposed in a form close to concentric circles, the light travels back while repeating reflection. In addition, the light inserted from a sharp angle (for example, about 15 °) is once reflected by the longitudinal reflecting wings 21a and then taken into the condensing tube 10a. In the example of FIG. 6, the reflected light seems to travel in a direction different from the point P, but actually, after reflecting off the R portion of FIG. From the reflecting surface 20 on the 10 side surfaces, it goes to the vicinity of the point P through S1 and S2 in FIG. Next, the reflection in the Y-axis direction (vertical direction) in the light collection tube 10 will be described. Assuming that light is emitted from the point P in FIG. 5, the R portion is curved so that all the light reflected on the R portion is parallel to the Z-axis direction (horizontal direction). Further, as shown in FIG. 7, the incident sunlight at all angles is curved so as to be parallel to the Z-axis direction (horizontal direction) by the first reflection of the lateral reflection wing 22. However, although there is a part of the light reflected on the part of the lateral reflection wing 22 that does not advance in the parallel direction, the direction of the travel is not greatly deviated because the curve of the lateral reflection wing 22 is gentle. In summary, the reflection in the Y-axis direction (vertical direction) is summarized as follows. The incident sunlight at all angles travels in the Z-axis direction (horizontal direction) by the first reflection of the lateral reflection wings 22, and then the R part in FIG. 5. Will be reflected near the point P.
Moreover, the glass 30 is not an essential constituent requirement.

Specifically, as shown in FIG. 2, the condensing tube 10 is formed of a mirror partition plate in which the longitudinal reflecting wings 21 and 21a and the lateral reflecting wings 22 intersect at right angles, and has a glass on the front surface. 30, a light guide tube 41 is connected to the rear, and the condensed light is sent to an appropriate place in the handrail lowering device. In addition, the reflective surface 20 of the wall surface of the condensing tube 10 is not necessarily four sides of upper, lower, left, and right. For example, it may be a hexagonal honeycomb shape. Further, the unit condensing tube 10 formed by the vertical reflection wings 21 and the horizontal reflection wings 22 is not limited to the four sides of the top, bottom, left and right, and (1) to (4) in FIG.
