Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar lighting device of the type to be installed in eaves of a building.

[0002]

2. Description of the Related Art Conventional solar light collecting devices are mainly installed on the roof of a building as shown in Japanese Patent Laid-Open No. 3-249608, or installed on a roof or a veranda.

Further, although different from the daylighting device, there is a skylight as a device for collecting sunlight, and the installation place of this skylight is a roof or a rooftop.

[0004]

By the way, the above-mentioned conventional device has the following problems. (1) In order to guide the sunlight, which is lit by the lighting unit, into the room,
Optical ducts, optical fibers, etc. were required, and special construction for that was required. (2) Since the lighting unit is attached to the roof with a hole, there is a concern that rain may leak in the room. (3) Further, in the case of the skylight, since it is directly attached, even if it is desired to illuminate the place such as the center of the building on the first floor, there are cases where it cannot be attached to that place.

The present invention has the above-mentioned problems (problems) of the conventional ones.
It is an object of the present invention to provide a sunlight collecting device that solves the above problem.

[0006]

In order to solve the above-mentioned problems, the solar lighting device of the present invention is provided with a daylighter in the eaves of a building, and the sunlight collected from the daylighter is arranged below the daylighter. It was constructed so that it could be taken into the room through the window.

In this case, it is preferable that the daylighting device is constructed so that one or a plurality of flat plate prisms are rotated in the eaves of the building in response to the operation of the sun.

Further, it is desirable that the window for taking in the light collected by the lighting device into the room constitutes first light emitting direction changing means having the function of changing the direction of the light itself.

As the first light emission direction changing means, a window is used, a flat plate prism is used as an upper plate constituting the ceiling portion of the window, and a glass plate or the like is used as a lower plate constituting the floor plate of the window. Using a light-transmissive material, the inclined plate arranged from the outer tip of the upper plate to the inner tip of the lower plate is formed by arranging a reflector or a half mirror or a louver-shaped mirror. It can be configured so that the sunlight collected from the daylight collector is taken into the room and the light is guided also to the lower floor.

Further, as a window for taking in the sunlight taken by the daylighting device into the room, a second light provided with means for changing the direction of the sunlight taken up by the daylighting device outside a normal window. The emitting direction changing means can be configured.

In this case, as the second light emission direction changing means, a flat plate prism is arranged at an upper end portion of the ordinary window at an appropriate angle, and the sunlight collected from the daylight collector is arranged as described above. It is possible to change the direction through the flat prism and take it into the room.

Further, the second light emission direction changing means is
A first flat plate prism having a predetermined area is arranged on the upper end portion of a normal window, and a second flat plate prism is further arranged on the upper end portion of the first flat plate prism so as to be inclined, and the light is collected from the light collector. The sunlight may be configured so that the first light whose direction is changed by the second flat plate prism and the second light whose direction is changed by the first flat plate prism are taken into the room.

Further, a plurality of the daylighting devices provided in the eaves of the building are arranged in the horizontal direction in association with the windows of the building located below the eaves. It is desirable to arrange a plurality of the first light emitting direction changing means and / or the second light emitting direction changing means.

[0014]

Since the solar lighting device of the present invention installs the lighting device by utilizing the eaves of the building, there is no risk of rain leakage into the room.

Further, since the sunlight shined from the lighting unit is guided into the room facing the window directly below the lighting unit, there is no need for a light guiding means such as an optical duct or an optical fiber, so that the facility of the existing building is large. It can be installed without modification.

Further, the flat plate prism constituting the daylighting device is rotated so as to have an appropriate angle according to the operation of the sun,
The part to be attached to the eaves is only one or a plurality of flat plate prisms and its rotating mechanism, and the other control mechanisms can be installed on the ground. Therefore, the part to be attached to the eaves can be made lightweight and compact.

In the device of the present invention, the sunlight drawn by the daylighting device is taken into the room through a slightly modified window, but in this case, when a normal window is used, Since it is only necessary to install a flat prism as an attachment part, retrofitting work to an existing building is easy,
Also, when using a bay window, it is sufficient to install a bay window having a configuration described later, and therefore the mounting is easy.

No matter which type of window is used, sunlight is guided into the room through the window, so that it does not give an uncomfortable feeling to a person in the room.

The light H1 refracted by 1 and the light H2 reflected by the inclined plate 43, and the light heading toward the first floor corresponds to the light H3 transmitted through the inclined plate 43.

Therefore, since the amount of sunlight toward the first floor depends on the amount of light transmitted through the inclined plate 43, the inclined plate 43 using the half mirror shown in FIG. 4B is used as the inclined plate 43. If the upper plate 41A constituted by a special prism as shown in FIG. 4D is used, the glass parts G1, G2 ... Area and further inclined plate 43
In the case of installing the above, since it is determined by both the characteristics of the half mirror of the inclined plate 43, it is necessary to design in consideration of daylighting on both the first floor and the second floor.

When the inclined plate 43R is composed of the louvered mirror shown in FIG. 4C, the inclined plate 43R is used.
It is convenient because the amount of light traveling toward the first floor can be adjusted by adjusting the degree of opening of each mirror constituting the.

Next, as the light to be taken into the room on the first floor, the sunlight transmitted from the second floor side under the above conditions is shown in the second light emission direction changing means 6 as shown in FIG.

Two or more are installed and it corresponds to each of these daylighters.
If the first and second light emission direction changing means provided in each room on the first and second floors are also installed by the number of daylight collectors, the amount of light taken into each room can be made appropriate. .

In the above embodiment, the example of the first floor and the second floor is explained, but in the case of a one-story building or a three-story building, or when the present invention is applied to a part of a high-rise apartment,
It is applicable by installing the thing of the said Example in the eaves of the living room which needs sunlight, and providing the following light emission direction changing means with respect to the window of the said living room.

In this case, for example, when it is desired to install the device only in the one room on the second floor of the condominium on the window side, the second light emitting direction changing means 6 is provided as a set with the daylighting device 3, etc. It is necessary to make a combination according to the application place of.

Further, in the above-mentioned embodiment, the operation of the sunlight collecting device of the present invention is emphasized, so that the sunlight naturally taken in through the windows on each floor, and the sunlight on the first floor side is 2 In addition to the sunlight guided from the floor side,
There is also sunlight that is incident on the flat plate prism of the light emission direction changing means, but the description of the sunlight collecting device of the present invention will be made without mentioning that, and as a supplement to the amount of sunlight that is naturally taken in. Did.

[0048]

As described above, since the sunlight collecting device of the present invention installs the daylighting device in the eaves of the building and takes in the collected light into the room through the window of the living room, it is as follows. Has excellent effect. (1) Since the place where the daylighting device is installed is the eaves of the building, there is less risk of rain leaks in the room as compared to the conventional installation on the roof or rooftop. Further, since a light guide means such as an optical duct or an optical fiber is not necessary, this device can be attached without major modification of the building. Therefore, since the houses are densely packed, it is most suitable as a facility for supplementing the daylight for a house where the natural light is insufficient. (2) Since the rotating part of the light collector is only a flat prism, it can be made light and compact, and can be easily installed in eaves. (3) The light emitting direction changing means for guiding the light from the daylight collector to the room basically uses a window, and auxiliary means such as a prism for changing the light direction to the room side with respect to the window. Since it is provided, both the bay window type and the normal window type can be applied with a small amount of retrofitting work without significantly modifying the existing building. (4) Further, in any of the window types, sunlight is taken into the room through the window, so that it is natural for the person in the room and does not cause any discomfort. (5) If the number of the daylighting devices and the light emitting direction changing means are set according to the number of windows or the width of the windows, the amount of daylight can be greatly increased. (6) If a louver-shaped mirror is used as the inclined plate of the first light emission direction changing means, the amount and direction of light guided to the first floor can be arbitrarily adjusted by adjusting the opening degree of the louver. .
