FIG. 1 is a schematic perspective view for explaining the principle of the sunlight collecting device according to the present invention. Axial direction of shaped concave reflector 1 (X-X direction)
A lens plate 3 with a cylindrical surface is disposed on the lens plate 2, and 3 is a light guide whose light-receiving end is disposed at the focal line position of the lens plate 2. Sunlight L is introduced into the light guide 3 and transmitted through the light guide 3 to any desired location for use in identification or other uses. Therefore, in Fig. 1, for example, the width W 1 of the light receiving end of the light guide 3 is 2 mm, the length L 1 is 8 mm considering spherical aberration, and the radius of curvature of the lens surface of the lens plate 2 is 200 mm. , length L 2
If it is 100 mm, the width W 2 of the lens plate 2 is 8 mm, the length Z 1 from the lens surface to the focal point is 100 mm, the width W 3 of the cylindrical concave reflector 1 is 400 mm, the length L 3 is 100 mm,
The focal length Z 2 is 400 mm, and the light receiving area (W 3 × L 3 )
The sunlight received at 40000 mm 2 is reduced to an area of W 1 × L 2 = 16 mm 2 , that is, the sunlight received at the cylindrical concave reflector 1 is concentrated 2500 times and introduced into the light guide 3. However, if sunlight is focused using a Fresnel lens with a diameter of 40 cm as in the prior art, the diameter of the solar image will be approximately 10 mm taking into account spherical aberration and chromatic aberration, and in that case, (π × 20 2 )/
(π×(1/2) 2 )=1600, meaning that it could only be concentrated 1600 times. As described above, according to the conventional technology, since sunlight is focused using a lens, there is a serious problem of chromatic aberration, and it is difficult to introduce high-quality sunlight into the light guide 3. However, the present invention According to the above, since the cylindrical concave reflecting mirror 1 is used to focus sunlight over a wide area, there is no problem of chromatic aberration in this respect, and the light introduced into the lens plate 2 is reflected by the lens. Since it is confined within the plate 2 and propagated to the light receiving end of the light guide 3 while reflecting off the wall surface of the lens plate 2, there is no problem of chromatic aberration at this point, and high quality sunlight is inside the light guide 3. In other words, the light closest to natural light is introduced. In this case, if the peripheral side of the lens plate 2 is formed into a reflective mirror surface or a cladding layer is formed on the peripheral side, the light introduced into the lens plate 2 will not leak to the outside and will be efficiently used as a light guide. Guided by 3.

FIG. 2 is a schematic configuration diagram for explaining one embodiment of the present invention, in which 1 is a cylindrical concave reflecting mirror;
3 is a lens plate, 3 is a light guide, and 4 is a support frame for supporting the cylindrical concave reflector 1 to the light guide 3. As in the previous embodiment, the cylindrical concave reflector 1 allows the Y-Y axis to be In this embodiment, sunlight L focused in the direction of the X-X axis is focused by the lens plate 2 and introduced into the light guide 3. In this embodiment, a single cylindrical concave reflective A plurality of rectangular lens plates 2 (two in the figure) are used for the mirror 1, and the lens surfaces of these lens plates 2 are arranged in parallel along the focal point of the cylindrical concave reflecting mirror 1. In this way, when multiple lens plates are used for a single cylindrical concave reflector, the distance from the lens surface of lens plate 2 to the focal point is shortened compared to the case where one lens plate is used. There are advantages such as the overall size can be reduced and assembly work of the device becomes easier. In addition, if a rectangular lens plate is used as the lens plate 2 as in this embodiment, when a plurality of lens plates are arranged in parallel as shown in the figure, it becomes easy to join adjacent lens plates. , the assembly of the device becomes easy and reliable. In addition, when using a fan-shaped lens plate as shown in FIG. 1, triangular plates 5 that cooperate with the lens plate 2 to form a rectangular shape as a whole are glued on both sides as shown in FIG. Then, as in the embodiment shown in FIG. 2, when a large number of lens plates 2 are arranged in parallel, assembly can be made easy and reliable. If the mirror surface is formed, the light propagating within the lens plate 2 is efficiently transmitted to the light guide 3 without being introduced into the triangular plate 5. Furthermore, in the above embodiments, the sunlight focused in the Y-Y axis direction by the cylindrical concave reflecting mirror 1 is now focused in the X-X axis direction by the lens plate 2. In that case, considering one lens plate, since the lens surface 2' of the lens plate 2 draws an arc, the distance from the cylindrical concave reflector 1 to the lens surface 2' is the same as the center of the lens plate. It is different at both ends and becomes longer towards the end. 4 and 5 are schematic diagrams for explaining this relationship. FIG. 4 is a view of the cylindrical concave reflecting mirror 1 viewed from the side, and FIG. 5 is a diagram of the cylindrical concave reflecting mirror 1. 1 as seen from the front direction. In the figure, 2'a indicates the center position of the lens surface, and 2'b indicates the end position. As mentioned above, the lens surface 2' draws an arc. Therefore, the distance l 1 from the cylindrical concave reflector 1 to the position 2'a at the center of the lens surface is less than the distance l 2 from the cylindrical concave reflector 1 to the position 2'b at the end of the lens surface. short. Therefore, as shown in Figures 4 and 5,
If the distance between the cylindrical concave reflector 1 and the lens plate 2 is determined so that the reflected light from the cylindrical concave reflector 1 at position 2'c focuses on the lens surface, then 2'
At the position c, it is possible to introduce all the reflected light from the cylindrical concave reflecting mirror 1 into the lens plate 2, but at the center part 2'a or the end part 2'b, as shown in FIG. As shown, part of the light cannot be introduced into the lens plate 2. FIG. 6 is a diagram for explaining an example of a lens plate that solves these drawbacks. As shown in the figure, a large number of strip-shaped lenses each forming a part of the lens surface 2' are used. 2 1 ,
2 2 ... 2 5 are glued together using optical glue or the like so that the distances from the cylindrical concave reflector 1 are the same, and when done this way, at almost all positions, The positions from the cylindrical concave reflecting mirror 1 to the lens surface 2' are approximately equal, and the reflected light reflected by the cylindrical concave reflecting mirror 1 can be efficiently introduced into the lens plate 2.

FIG. 7 is a schematic configuration diagram for explaining the configuration of the three parts of the light guide of the sunlight collecting device using a large number of fan-shaped lens plates as the lens plates 2 as described above. Since the focal line image of the lens plate 2 is rectangular, if the light-receiving end face of the light guide 3 is configured to be square according to the focal line image of the lens plate 2, the cylindrical concave reflecting mirror 1 and the lens plate 2 Focused sunlight can be introduced into the light guide 3 most efficiently, and the light guide 3 from each lens plate 2 can be introduced into the light guide 3 most efficiently.
The arrangement process of the light guide 3 is easy because it can be stacked and integrally glued together as shown in the figure. In FIG. 7, reference numeral 6 denotes a circular light guide, and when the square light guide integrally formed as described above is connected to the circular light guide 6, the connection is difficult because the light guide has no corners. The subsequent arrangement of the light guide becomes easy, and the light transmission efficiency is also good.
