Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides solar lighting that collects sunlight using a solar collector and transmits the collected light through a light guide to a room that requires illumination. In particular, in multi-story housing complexes, a solar collector is placed at approximately the same height as the floor of the floor to be illuminated, and thereby This allows the owner to freely observe and maintain the sunlight collection device that illuminates the room.

2. Description of the Related Art A solar lighting system in which sunlight is collected by a solar collector, and the collected sunlight is guided through a light guide into a room to be illuminated has already been extensively proposed. Figure 1 is a schematic configuration diagram showing an example of a conventional solar lighting system. In the figure, 1 shows a partial side cross section of a multi-story apartment building, 2 shows the nth floor (n is a natural number), and 3 is (n-1)
0 indicates the ceiling of the floor; 4 indicates a solar collector; 5 indicates a light guide; and 6 indicates a light emitter. The sunlight thus guided is emitted from a light emitter 6 and used for illumination. Accordingly, in the conventional solar lighting method described above, in order to illuminate a room on the (n-1) floor (for example, n = 5), the sunlight collecting device 4 is placed on the floor of the room on the 5th floor, which is approximately the same as the floor surface of the room on the 5th floor. Even if the solar collecting device 4 breaks down, the solar collecting bag @4 is actually used for fe.
Residents on the floor could not repair the solar collector without permission. In particular, in cases where the multi-story housing complex is a multi-unit housing complex, as shown in the illustrated example, the solar collection bag w4 used for lighting in the 41 bamboo room (despite being owned by the resident on the 24th floor) It is located on the 5th floor in a part that is owned by 11 people, and the residents of 41"+X have 1-;
In addition, the resident on the 5th floor, 1d, is indifferent to the solar collection equipment owned by someone else, as it is located in a place that should be his/her own. The construction was very sloppy, and the solar lighting was not always working at its best. In addition, if a child on the upper floor plays a trick with the sunlight collecting device and messes with the sunlight, or if the sunlight collecting device is a fixed sky light collecting type. When an internally reflective type of light guide vibrator is used as a light guide, the light guide pipe acts as a bell, allowing residents on the upper floor to see into the rooms on the lower floor through the solar collector. However, there were drawbacks such as the possibility of an invasion of privacy.

The present invention has been made in order to eliminate the drawbacks of the prior art as described above, and as shown in FIG. In other words, the solar collector that illuminates one's own room should be installed at a location that corresponds to the owner's room. It is arranged within the control range to facilitate maintenance and management of the solar light collecting device. The sunlight collecting device 4 may be, for example, a solar collecting device whose light-receiving surface always faces the sun to collect direct sunlight as shown in FIG. 3, or a solar collecting device as shown in FIG. As shown in Figure 2, a solar collector is used that collects indirect light from the sun with a fixed light-receiving surface.These devices are installed at the same time, and the collected sunlight is passed through a common light guide. If the light is transmitted to the illuminated area, more effective illumination can be achieved. In FIG. 2, reference numeral 7 indicates an optical outlet, to which a solar lighting stand (not shown) (see, for example, Japanese Patent Application No. 55-87280) is connected.

FIG. 3 is a schematic configuration diagram showing an example of a direct sunlight collecting device previously proposed by the present applicant. In the figure, 8a is a cylindrical base portion, 8b is a transparent dome-shaped head, and these constitutes a capsule 9 for a solar collector, and in use, the capsule 9 has a solar collector 1 as shown in the figure.
0 is stored. This sunlight collection device 10 includes lenses 11 (for example, one lens, two lenses,
4, 7, or 9), a sunlight direction sensor 12 for detecting the direction of the sun, a support frame 13 that holds these together, and a first sensor for rotating the support frame 13. -14, a first motor 15 that rotates the first rotation shaft 14, a support arm 16 that supports the lens 11 to the motor 15, and a support arm 16 disposed perpendicular to the first rotation shaft 14. The sunlight direction sensor 12 detects the direction of the sun and outputs a detection signal thereof. The motor is controlled so that the lens 11 always faces the sun, and the sunlight focused by the lens 11 is introduced into the optical conductor cable 5 whose light receiving end is disposed at the focal position of the lens, and the light is A conductor cable leads to the room of the person who owns the place where the solar collector is installed. Although FIG. 3 shows a solar collector that collects only solar energy, the applicant has also proposed a solar collector that collects solar energy and solar thermal energy at the same time. , when using such a solar collector as a solar collector, solar thermal energy can also be utilized.

This is a schematic configuration diagram showing an example of a collecting device (see Japanese Patent Application No. 55-157979).
It is formed into a hexagonal or circular cylindrical body, and the sunlight receiving port at the top has a relatively wide area, and the light exit port has a relatively narrow area. (In ~, the inner wall surface of the cylinder side is discontinuously provided with a taber, and the light received from the relatively wide area of the light receiving opening is directed along the inner wall surface of the cylinder side toward the light exit. As the light travels, it is reflected by the inner wall surface of the cylinder, focused on a relatively narrow area of the light exit, and is effectively introduced into the light guide cable attached to the light exit, passing through the light guide cable. You will be asked to go to the room of the PTR holder where the solar collection device is installed.Now,
The cylindrical body side is a cylindrical body, and the cylindrical body is divided into four parts, and the taper angle θ□ of the 201 part is set to 200, and the taper angle θ of the 202 part is
2 is 10°, the taper angle θ3 of the 203 part is 5°,
The taper angle θ4 of the 204 part is 2.5 degrees, the length of the 201 part is 30 mm, and the length of the 202 part is 6011.203
Part length 180 penalty, 204 Part length 270
If the diameter of the light exit port is 10mm, the diameter of the light receiving port will be approximately 10811mm, and if we ignore the light transmission loss on the wall surface of the cylinder, the sunlight introduced through the light receiving port will have approximately 117 times the light energy. The light is densely focused and guided to a light exit and introduced into a light guide cable.

As is clear from the above description, according to the present invention, when a solar light collection device is installed in each household in a multi-story housing complex to provide solar lighting for each household, the scope of ownership or management of each household is Since the solar collectors of the house are installed in locations within the building, each solar collector can be ideally managed and solar energy can be used efficiently.
