At the winter solstice, all the sunlight 15 incident on the triangular prism Bliz A 8 reaches the bottom 6 of Bliz L, l, and 2. The thick IS r15' which is incident on the triangular prism 8' is repeatedly reflected and totally reflected within the prism 8' and reaches the prism 1'. These things happen during the summer solstice.
Everything else is the same except that prism 8' has been replaced. In the morning before noon, sunlight 15 and 15' enter triangular prisms 8 and 8' from the southeast, and The inside of 8' and 1 and 1' is refracted from the east force to the west force and reaches the bottoms 6 and 6'. The refracted sunlight incident on the parts near the west ends of the triangular prisms 8 and 8' is reflected eastward by a reflecting mirror 12 provided on the west side, and then reaches the bottom parts 6 and 6'.

In the afternoon after noon, sunlight 15 and 15' enter the triangular prisms 8 and 8' from the southwest direction. Sunlight 15 and 15' incident on the triangular prisms 8 and 8' are +'i
Contrary to f+, part of it reaches the l bottoms 6 and 6', including being reflected in the west direction by the reflecting mirror 12 provided on the east ψ11.

The total internal reflection critical angle Q of a triangular prism is expressed by the following formula.

nxSQ=1 n is the refractive index of the triangular prism When the refracted light 16 of the sunlight 15 incident on the side surface 2 of the regular cylindrical prism 1 is incident on the 9111 surface 6 at a total reflection critical angle or more, it is totally reflected on the side surface 6. be done. The minimum angle of incidence of such sunlight 15 on the five side surfaces 2 is defined as the critical incidence angle. The range from the critical incidence angle to the incidence angle 900 is defined as the allowable incidence φ. The sun whose angle of incidence with respect to the side surface 2 is within the permissible incident range)'(, 15 undergoes total reflection or repeats the curvature 1 and total reflection inside the triangular prism 1, and finally reaches the bottom surface B.

The refractive index of the triangular prism 1 is 1.8, and the apex angle 5 is 16.
If the side face 6 is not a reflective mirror, the allowable angle of incidence is 5.
The permissible incidence at 2° is only 1.1 at 58°. C but
If the side surface 2 is a reflective mirror, the allowable angle of incidence is 0° and 7. 'I right incidence; 6it enclosure 1. Hiroga 4) on L 900. In one case where the apex angle 5 is 60, the incidence range of one trough is 66° in the former case and &j, 480° in the latter case. The side 5 is used as a reflecting mirror, which serves as a permissive person (1, ■i'l・1), who plays the role of expanding the group.

The ratio is the ratio of the incident area to the receiving area is 1,lt -t 2) The maximum q, 1 area is 1% of the side 2 and the length is The loss is equal to the total area.

Light receiving part 4 of sunlight 15? i is equal to the area of rlJ and length of the bottom 6. In order to make the concentration ratio of sunlight 15 6 or more, the light receiving area needs to be 4 or less of the incident area, that is, when the side surface 2 and the bottom surface 6 are perpendicular, the apex angle 5 needs to be 180 or less.

As the seasons change from the spring equinox to the summer solstice and from the autumn equinox to the winter solstice,
C The altitude of the sun at noon is the vernal equinox 1. The angle changes vertically by 26.4 degrees around the altitude of the autumnal equinox. In order for one triangular prism 1 to receive sunlight 15 from the vernal equinox through the summer solstice to the autumnal equinox with a condensing ratio of 6 or more, the apex angle 5 of the triangular prism 1 must be 23.40 larger than the critical incident angle. In contrast, it is necessary to have a condensing ratio of 6 or more. Vertical angle 5 like this

Sunlight 15 incident near the apex 40 is refracted by the side surface 2, reflected by the side surface 6 as shown in FIG. 6(1), and then totally reflected by the side surface 2, after which it reaches the bottom surface B. Each time the refracted light 16 is reflected at the side surface 6 and totally reflected at the side surface 2, the incident angle increases by an angle corresponding to the apex angle 5. When the refracted light 16 reaches the bottom surface 6, the angle of the refracted light 16 with respect to the side surfaces 6 and 2 is sufficiently large. The bottom surface 6 is perpendicular to the side surface 2 and the bottom surface 6 of the refracted light 16
The angle of incidence on the bottom surface 6 is smaller than the critical angle of total reflection.
The light is refracted at the point and emitted to the outside of the triangular prism 1.

Sunlight 15 that enters near the bottom 60 of the side 2 of the triangular prism 1 is refracted by the side 2 and then directly returns to the bottom IT+76.
It reaches the bottom surface 6 after repeating the reflection on the side 6 and the total reflection on the side 2 several times. Since the number of reflections and total reflections of the refracted light 16 is small, the angle of the refracted light 16 with respect to the side surface 6 and the side surface 2 is not larger than m as shown in FIG. 6(2). The angle of incidence of the refracted light 16 on the bottom 4 is greater than the critical angle of total reflection, and if the bottom 6 is in contact with air, it will be totally reflected at the bottom 6.

The totally reflected No. 2 diffracted light 16 travels in the direction of the apex within the triangular prism 1, is reflected, and after repeating total reflection, is emitted to the outside through the side surface 2.

When a heat-resistant liquid or an adhesive-free elastic material is sandwiched between the bottom surface 6 and the light receiving plate 7 is mounted in close optical contact with the bottom surface 6, the critical angle of total reflection at the bottom surface 6 becomes large, and part of the refracted light 16 that is totally reflected at the bottom surface 6 increases. Most of the light can be refracted by the bottom surface 6 and received by the light receiving plate 7. By optically bringing the light receiving plate 7 into close contact with the bottom surface 6, it is possible to increase the portion of the refracted light 16 that can be received by the light receiving plate 7.

When the thick light 15 at an altitude of 5oO measured from the horizontal plane is incident on the side surface 2, it traces the optical path of the refracted light of the sunlight that enters every other point from the apex 4 of the side surface 2 to the bottom surface 6. Calculate the angle of incidence on the bottom surface 6 when it reaches 1fI6 and the angle of refraction into the air when it is totally reflected at the bottom surface. η, the result is ash jtd.

If the light receiving plate 7 is not optically brought into close contact with the bottom surface 6, only the back half of the sunlight 15 incident on the side surface 2 will be refracted by the bottom surface 6, and the rest will be totally reflected. Refractive index is 1.5
When the light-receiving plate 7 is brought into optical contact with the tree surface A using a heat-resistant liquid, the critical angle of total reflection is 56.40, and from 1, up to 95 of the sunlight 15 is refracted at the bottom surface 6 and received. Reach board 7.

When sunlight 15 from a horizontal plane at an altitude of 700 is incident on the side surface, if the light receiving plate 7 is optically brought into close contact with the bottom surface 6, only 56 beams of the solar bar 15 will be refracted by the bottom surface 6 in the same way. , the remainder is totally reflected. Light receiving plate 7 on the bottom 6
When they are brought into close optical contact, up to 93% of sunlight is refracted at the bottom surface 6 and reaches the light receiving plate 7.

Fold it once and enter the triangular prism 1. At this time, since the side surface 100 human incidence angle and the side surface 2's Ji'TI refraction angle are the same, the refracted sunlight 16 appears to be the same as the side surface 10 and τI1
It is expressed as a straight line drawing 1 side 2.

When the angle of incidence of the refracted light 16 on the side surface 10 is larger than the critical angle for total reflection, the refracted light 16 is totally reflected on the side surface 10 and does not reach the triangular prism 1.

The condensing ratio when adding ° is 4.0.

In Figure 4 (21), the apparent critical incident angle with respect to the side surface 9 is 21.5°.The condensing ratio at the critical incident angle is 8.9
So, when 23.40 is added to the critical incident angle, the condensing ratio is 6.
It is 6. Refracted light 16 with 26.4° added to the critical angle of incidence
The angle of incidence on the side surface 10 is 1°, and total reflection occurs.□It reaches the side surface 2 at a angle smaller than Shougetsu's 66-7°.

In FIG. 4(3), the apparent critical angle of incidence with respect to the side surface 9 is 21.5°. The concentration C1 ratio and the optical path of the refracted light 16 are the same as in FIG. 4 (21).
