Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a solar light collecting device that collects sunlight and transmits the collected sunlight through a light guide to a room that requires illumination. Regarding light lighting devices, in particular, in a multi-story apartment complex, a solar light collection device that is intended to illuminate a room is placed at a position approximately at the same height as the floor of the floor to be illuminated, and then This allows the owner of a room to freely observe and maintain the sunlight collection device that illuminates the room.

2. Description of the Related Art Various solar lighting devices have already been proposed in which sunlight is collected by a sunlight collecting device, and the collected sunlight is guided through a light guide into a room to be illuminated for illumination. FIG. 1 is a schematic configuration diagram showing an example of a conventional solar lighting device.
1 shows a partial side cross section of a multi-story residential complex, 2 shows the floor of the nth floor (n is a natural number), and 3 shows the ceiling of the (n-1)th floor. Further, 4 indicates a solar light collecting device, 5 a light guide, and 6 a light emitter, and as is well known, sunlight collected by the sunlight collecting device 4 is passed through the light guide 5 to a room that requires illumination. The solar light thus guided is emitted from a light emitter 6 to provide illumination. Therefore, the above-mentioned conventional solar lighting device is installed on the (n-1) floor, for example, when n=5,
To illuminate the rooms on the second floor, use the solar collector 4 to 5.
It is installed on a surface that is approximately at the same height as the floor of the room on the second floor, so that even if the solar light collecting device 4 breaks down, the solar light collecting device 4 is actually used. Residents on the fourth floor were unable to repair the solar collector without permission. In particular, when the multi-story housing complex is a condominium, as shown in the example,
Solar collector device 4 used for lighting the room on the 4th floor
Although it is owned by the resident on the 4th floor, it is located in the area owned by the resident on the 5th floor.
The residents on the 5th floor have a weak sense of ownership regarding the solar collection equipment they own, and the residents on the 5th floor feel that the solar collection equipment owned by others is placed in a place that should originally belong to them. As a result, they were not interested in handling the solar collector, and the solar collector was handled roughly, and the solar lighting was not always operating in the best condition. In addition, if a child on the upper floor plays a trick with the solar collector, blocking the sunlight or staining the solar collector, or if the solar collector is a fixed sky light collecting type. When an internally reflective light guide pipe is used as a light guide, the light guide pipe acts as a periscope, allowing residents on the upper floor to see into the rooms on the lower floor through the solar collector. , there were drawbacks such as the risk of infringing on privacy.

The present invention has been made to eliminate the drawbacks of the prior art as described above, and as shown in FIG.
be at approximately the same height as the floor of the room on the nth floor.In other words, the solar light collection device that illuminates your room should be installed at a location that is owned by your room. The solar light collecting device is placed within the control range of the solar power collecting device, thereby facilitating maintenance and management of the solar light collecting device. In addition, the second
In the figure, numeral 7 indicates a light 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 collection device previously proposed by the applicant, and in the figure, 8a
8b is a cylindrical base portion, and 8b is a transparent dome-shaped head, which constitute a capsule 9 for a solar collector.
A sunlight collecting device 10 is housed therein as shown. This sunlight collecting device 10 includes a lens 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. The rotating shaft 14 of the first rotating shaft 1
4, a first motor 15 that rotates the lens 11;
A support arm 16 supporting the motor 15, a second rotation shaft 17 disposed perpendicular to the first rotation shaft 14, and a second motor rotating the second rotation shaft 17 (see FIG. ), etc., the direction of the sun is detected by the sunlight direction sensor 12, and the motor is controlled by the detection signal so that the lens 11 always faces the direction of the sun. The focused sunlight is introduced into a light guide cable 5 whose light receiving end is arranged at the focal position of the lens, and through the light guide cable, ownership of the place where the sunlight collecting device is installed is obtained. Lead to someone's room. 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.

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 thermal energy can be used efficiently.
