Description of the Related Art A conventional solar lighting apparatus will be described with reference to FIGS. 2A and 2B show the principle of construction of two lighting prisms incorporated in a conventional solar lighting device, wherein FIG. 2A is a perspective view when the solar altitude is low, and FIG. 2B is a perspective view when the solar altitude is high. FIG. 3 is a cross-sectional front view of an example of attachment to a frame of the conventional solar lighting device, and FIG. 4 is a plan view of the conventional solar lighting device. As a specific mechanism of a conventional sunlight collecting apparatus, for example, a mechanism described in JP-A-61-180217 is known. FIG. 2 shows a configuration principle of a daylighting prism incorporated in the sunlight daylighting device described in the publication, (A) is a perspective view when the solar altitude is low,
(B) is a perspective view when the sun altitude is high, and the one described in the publication discloses two lighting prisms P as shown in FIG.
1 and P 2 are independently rotated with the movement of the sun to control the emitted light in a predetermined direction. For this reason, the outgoing light of the sun is efficiently illuminated directly below the sunlight collecting device throughout the day. Next, a specific configuration of a conventional solar lighting device will be described with reference to FIGS. FIG. 3 is a cross-sectional front view of an example of attachment of a conventional solar lighting device to a frame, wherein 1 is a solar lighting device, 2 is two lighting prisms arranged at predetermined intervals, 3 is a dome cover, Denotes a light duct, 5 denotes an indoor light distribution plate, and 6 denotes a frame. That is, the conventional sunlight lighting device 1 includes the lighting prism 2, the dome cover 3, the light duct 4, and the indoor light distribution plate 5, is inserted and mounted on the frame 6, and the sunlight is directed downward through the sunlight lighting device 1. The light is emitted, and the emitted light is distributed indoors through the indoor light distribution plate 5. FIG. 4 is a plan view of a conventional daylighting device. The daylighting device is provided concentrically with the daylighting prism 2 disposed outside the daylighting prism 2 unlike the configuration of FIG. The rotating ring 7 formed is made of the same material (polycarbonate or the like) as the lighting prism 2 and, for example, four holding plates 8a to 8d are arranged so as to cross each other as shown in FIG. Are configured to be integrally rotated. Although not shown in FIG. 4, a gear is engraved on the outer circumference of the rotating ring 7, and the rotating ring 7 is rotated by receiving a torque from a driving gear 9 a of the rotary driving device 9. Note that S is a support frame of the rotating ring 7. That is, in a conventional solar lighting device, two lighting prisms are rotatably arranged in a lighting part, the rotation angles of these lighting prisms are controlled according to the altitude and azimuth of the sun, and refracted by the lighting prism. The emitted sunlight is emitted in a predetermined direction, and the emitted light is distributed indoors through a light duct and an indoor light distribution plate provided below the lighting prism, For this daylighting prism, for example, a transparent material such as acrylic or polycarbonate was used, and further, the direction of rotation of the transparent prism was controlled so that emitted light would always be directly below two transparent daylighting prisms.
