Description

  The present invention relates to a solar light guide that guides sunlight into a room such as a house.

  Conventionally, in order to guide bright sunlight into a room such as a house, sunlight is directly guided through a glass window provided on a wall surface or a skylight provided on a roof or the like.

  However, although sunlight reaches a room having a glass window or skylight facing south, sunlight does not sufficiently enter the basement or north room that is not in contact with the outside from the window.

  For example, Patent Document 1 discloses a solar light guide device that guides sunlight into a basement or the like. Patent Document 2 discloses that the light guide is branched to split sunlight into a plurality of rooms.

  However, the solar light guide device of Patent Document 1 has flexibility but is composed of one light transmission hose, cannot be branched, and can guide light only to one point at the tip. .

  In addition, the daylighting device of Patent Document 2 branches from a main pipe line to a branch pipe line via a branching reflector, and the main pipe line and the branch pipe line are connected at the building construction site of the building. It is necessary to adjust the angle accurately, and a great deal of labor is required for installation. It must also be installed as part of the building when it is being constructed.

  The object of the present invention is to solve the above-mentioned problems, and even in a room that does not have a room having a glass window or skylight, or in a position away from the glass window or skylight, the sunlight collected in the existing building is used. In contrast, an object of the present invention is to provide a solar light guide that can easily guide light to an arbitrary portion.

  In order to achieve the above object, a solar light guide according to the present invention bundles a plurality of flexible light guide tubes having a light reflecting material having high reflectivity with respect to light on the inner surface, and covers the outer surface. It is characterized by being covered with wood.

  According to the sunlight light guide according to the present invention, sunlight can be guided to an arbitrary place by bundling a plurality of flexible light guide tubes.

It is explanatory drawing of the state which attached the solar light guide of the Example to the building. It is a longitudinal cross-sectional view of a light guide tube. It is a cross-sectional view of a solar light guide. It is a perspective view of the front-end | tip part of the sunlight light guide located in the lighting window side. It is a fragmentary perspective view of the state where the light guide tube was arranged in parallel.

The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 shows an explanatory diagram of a state in which a solar light guide 1 in this embodiment is attached to a building. In order to guide sunlight from a daylighting window provided on the roof of a building H such as a building or a house, a plurality of tubular light guide tubes 2 having a hollow inside are bundled to have flexibility. A solar light guide 1 is attached to the building H.

  FIG. 2 shows a longitudinal cross-sectional view of the light guide tube 2, and a layer of the light reflecting material 3 having a high reflectance is provided on the inner surface of the light guide tube 2 having a circular cross section by pasting, coating, vapor deposition, or the like.

  In order to create the light guide tube 2, for example, aluminum or the like, which is a highly reflective material having a thickness of about 0.2 mm, is formed on one side of a flexible strip-shaped strip material such as soft synthetic resin or light metal. The tube body is formed by a forming machine or the like so that the layer of the light reflecting material 3 becomes the inner surface after the layer of the light reflecting material 3 is formed by pasting a sheet or applying a highly reflective paint. It can be manufactured by rolling in the longitudinal direction and then forming.

  Thus, since the light guide tube 2 is mainly formed from a flexible strip, the light guide tube 2 itself has appropriate flexibility. Furthermore, by providing a metal sheet or the like of a highly reflective material on the inner surface of the light guide tube 2, the entire light guide tube 2 is provided with an appropriate shape retention, and the shape is maintained when the light guide tube 2 is bent. It becomes possible to do.

  Alternatively, it can also be produced by applying the light reflecting material 3 made of a highly reflective paint on the inner wall of an existing flexible tube and sequentially connecting these tubes. Further, the light reflecting material 3 having high reflectivity such as aluminum may be wound around and attached to the outside of the transparent and flexible synthetic resin tube.

  As shown in FIG. 3, the solar light guide 1 has, for example, seven light guide tubes 2 a to 2 g each having an inner diameter of about 3 to 10 cm, and the entire outer periphery of the bundled light guide tubes 2 a to 2 g. It is covered with a covering material 4 such as synthetic rubber.

  FIG. 4 shows a perspective view of the daylighting unit 5 of the solar light guide 1 arranged on the side of the daylighting window for daylighting. One end of each of the light guide tubes 2a to 2g is processed into a regular hexagonal cross section, and is fitted into a regular hexagonal frame 6a to 6g made of a synthetic resin having a light reflecting material applied to a highly reflective metal or an inner surface, for example. The lighting part 5 is covered with a covering material that is not used.

  Thus, in the lighting part 5 of the sunlight light guide 1, it is preferable to form a honeycomb structure by bundling regular hexagonal light guide tubes 2a to 2g. By making the daylighting part 5 into a honeycomb structure, the light guide tubes 2a to 2g can be arranged efficiently, there is no gap between the light guide tubes 2a to 2g, and sunlight is efficiently used even from a small part. Daylighting. The shape of the daylighting window can be matched with the cross-sectional shape of the solar light guide 1 in which a plurality of light guide tubes 2 are bundled.

  Further, in order to collect sunlight more efficiently on the daylighting section 5 of the solar light guide 1, a condensing lens and a condensing concave mirror are arranged around the solar light guide 1, and the light lens and the condensing concave mirror are used. The collected sunlight may be guided to the daylighting unit 5 of the solar light guide 1.

  In the present embodiment, one end of the light guide tube 2 that is the daylighting unit 5 has a regular hexagonal cross section. If the side portions of the light guide tube 2 are in contact with each other and are arranged so that there is no gap between the adjacent light guide tubes 2, an appropriate polygonal cross-sectional shape can be adopted.

  As shown in FIG. 2, the sunlight L guided from one end of the light guide tube 2 travels in the light guide tube 2 by being repeatedly reflected by the light reflecting material 3 in the light guide tube 2.

  As described above, since the solar light guide 1 in which the light guide tubes 2a to 2g are bundled has flexibility, the daylighting unit 5 is provided on a daylighting window or the like provided on the roof of the building H as shown in FIG. The solar light guide 1 can be pulled into the interior of the building H while being bent and freely bent along the wall of the building H or along the back of the ceiling.

  In addition, as shown in FIG. 3, in the sunlight light guide 1 in a state where the seven light guide tubes 2a to 2g are bundled, the diameter is too thick and the light guide tube 1 is arranged in a flat place such as between the walls or the ceiling. In some cases, it cannot be bent at a right angle.

  In such a case, as shown in FIG. 5, when a part of the covering material 4 is peeled off and the light guide tubes 2 a to 2 g are bundled, the arrangement can be easily made. In this way, by arranging the light guide tubes 2a to 2g in a flat shape, it is easy to be placed between the walls and the narrow flat part of the ceiling, and to be bent easily.

  Further, by partially removing the covering material 4, as shown in FIG. 1, a part of the light guide tubes 2a to 2c of the solar light guide 1 is drawn into the room Ha on the second floor, for example, and a part of the light guide tubes It is also possible to branch 2d and 2e into the room Hb on the first floor and pull in, and partly guide the light guide tubes 2f and 2g into the room Hc which is a basement. And the sunlight guided from the front-end | tip part of the light guide tubes 2a-2g will irradiate in each room.

  In this embodiment, the solar light guide 1 in which seven light guide tubes 2 are bundled has been described as an example. However, the light guide tube for one more turn around the seven light guides is particularly necessary at a place where a light amount is required. A solar light guide 1 can be used by bundling a total of 19 pieces including 12 pieces. By bundling many light guide tubes 2, more light can be guided. The number of the light guide tubes 2 of the solar light guide 1 can be changed as appropriate to adjust the light amount and the amount of light.

  Since the solar light guide 1 is composed of a flexible tube covered with the covering material 4, the light guide tube 2 can be guided to the place where the light guide tube 2 should be guided only by peeling off the covering material 4 at the site of the building H. It can be easily branched, no connection or adjustment work is required, and the installation work on site can be performed very easily. Moreover, it may replace with the coating | covering material 4 and you may make it arrange | position the binding tool which bundles the some light guide tube 2 in predetermined spacing. The light guide tube 2 can be branched by releasing the binding tool.

  As described above, the light guide tubes 2a to 2g can guide the sunlight L incident from the daylighting unit 5 to the rooms Ha, Hb, and Hc without using a reflecting mirror or the like.

  In addition, when light is guided, a part of sunlight is converted into heat in the light guide tube 2 and the sunlight light guide 1 has heat. Therefore, the covering material 4 preferably has heat insulation.
