  However, in the above-described blindfolded lattice structure, when the illumination is turned on indoors at night and the interior of the building becomes brighter than the exterior, the interior of the building becomes easy to see from the gap between the lattices, and a sufficient blindfold effect cannot be obtained.

  The present invention has been made in view of such points, and an object thereof is to provide a blindfold louver capable of obtaining a sufficient blindfolding effect even at night when the interior of a building is bright.

  In order to achieve the above object, the present invention provides a plurality of rod-shaped blindfolds arranged in parallel at predetermined intervals on a wall surface having an opening of a building, and at least one end of the plurality of blindfolds. A support body disposed substantially perpendicular to the blindfold body and supporting an end of the blindfold body, wherein the support body is formed in a cylindrical shape having an inner surface that reflects light, and a light source is provided therein. Each of the blindfolds is formed in a cylindrical shape having an inner surface that reflects light, and the interior thereof communicates with the interior of the support, and the wall on the building exterior side of each of the blindfolds has the support It is a blindfolded louver in which an outward light emitting part for emitting light from the light source of the body is formed.

  According to the present invention, by emitting light from the outward light output portion of the blindfold, it becomes difficult to see the interior from the outside of the building even at night, even in a bright state of the building, and a sufficient blinding effect is obtained. .

  An inward light emitting portion for emitting light from the light source of the support may be formed on the wall surface of each blindfold inside the building. In such a case, since light can be emitted toward the inside of the building, the light from the blindfold louver can be used as auxiliary illumination inside the building.

  Moreover, the said blindfold may be arrange | positioned on the outer side of the window surface of a building. In such a case, the light emitted from the inward light emitting portion of the blindfold is reflected by the window. As a result, the inside becomes harder to see from the outside of the building, and the blinding effect is further improved.

  The inward light outgoing portion may be formed wider than the outward light outgoing portion. In such a case, the amount of light reflected on the window surface increases, and as a result, the interior becomes more difficult to see from the outside of the building.

  The wall surface on the building interior side of each blindfold may be formed wider than the wall surface on the building exterior side. In such a case, it is easy to see the outside from the inside of the building, it is difficult to see the inside from the outside of the building, the outside scenery is easily seen, and a high blinding effect is obtained.

  The outgoing light portion may be set to have a higher reflectance with respect to light incident from the outside of the blindfold than other portions of the blindfold. In this case, since the blindfold reflects light from the outside such as the sun, the effect of blindfolding during the day is also improved.

  A low-luminance portion having a lower luminance than other portions may be formed on the wall surface of each blindfold inside the building. In such a case, when the outside is viewed from the inside of the building, the blindfold has a low brightness, and the outside can be easily seen from the gap between the blindfolds.

  According to the present invention, a sufficient blindfold effect can be obtained regardless of day or night.

FIG. 1 is an explanatory diagram showing an outline of the configuration of the blindfold louver 1 according to the present embodiment. FIG. 2 is a cross-sectional view taken along the line XX in FIG. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  The blind louver 1 is provided on a wall surface portion B having a window A as an opening of a building. The blindfold louver 1 is provided outside the window A. The blindfold louver 1 is arranged substantially vertically with respect to the blindfold body 10 at the upper and lower ends of the plurality of blindfold bodies 10 and the plurality of blindfold bodies 10 arranged in parallel at predetermined intervals in a state of being vertically oriented. The support 11 supports the end of the blindfold 10.

  The support body 11 is being fixed to the wall surface part B of a building. The support 11 is formed in a cylindrical shape with a square cross section, and light sources 20 are provided at both ends inside. An LED is used as the light source 20. The light source 20 is directed toward the side wall surface of the support 11 at an angle with respect to the axial direction of the support 11. As shown in FIGS. 3 and 4, the support 11 has an inner surface 21 with high light reflectivity. The inner surface 21 having a high light reflectivity may be realized by applying a coating that enhances the light reflectivity, or may be realized by forming the support 11 from a material such as aluminum having a high light reflectivity. May be.

  The blindfold 10 is formed in a hollow cylindrical shape. The blindfold 10 has a substantially trapezoidal cross section as shown in FIGS. 2 and 5, and in the cross-sectional shape, the short side 10a is directed to the exterior S1 side of the building, and the long side 10b is directed to the interior S2 side of the building. ing. As shown in FIG. 3, the interior of the blindfold 10 communicates with the interior of the support 11. As with the support 11, the blindfold 10 has an inner surface 30 with high light reflectivity. The inner surface 30 may be realized by applying a coating that enhances light reflectivity, or may be realized by forming the blindfold 10 with a material such as aluminum having high light reflectivity.

  As shown in FIGS. 1, 2, and 4, an outward light emitting portion 31 that emits internal light to the outside is formed on the wall surface on the building exterior S <b> 1 side of the blindfold 10. The outward light exiting portion 31 is formed in a rectangular shape that is long in the vertical direction. The outward light exiting portion 31 is formed of a milky white acrylic plate having a high light diffusibility. Therefore, as shown in FIG. 3, the light emitted from the light source 20 at the end of the support 11 travels while reflecting the inner surface 21 of the support 11, enters into each blindfold 10, and the inner surface of each blindfold 10. As shown in FIGS. 2 and 4, the light advances from the outward light exiting portion 31 of each blindfold 10 to the building exterior S1 side.

  The outgoing light portion 31 is set to have a higher reflectance with respect to light incident from the outside S1 of the blindfold 10 than the other portions of the blindfold 10. Specifically, the inner surface of the outgoing light portion 31 is rough and the outer surface of the outgoing light portion 31 is smoothly formed, so that the reflectance of light incident from the outside S1 is increased.

  As shown in FIG. 5, a low-luminance portion 40 is formed on the wall interior S <b> 2 side of each blindfold body 10, that is, on the wall surface on the long side 10 b side. The low luminance part 40 is realized by forming the outer surface of the blindfold 10 on the side of the building interior S2 rough.

  In the blindfold louver 1 configured as described above, the interior S2 is hardly seen from the exterior S1 of the building by the plurality of blindfolders 10 arranged in the daytime without causing the light source 20 to emit light. Moreover, since the reflectance of the light of the outwardly outgoing light part 31 of the blindfold 10 is high, the solar light is reflected by the outwardly outgoing light part 31, and the interior S2 becomes less visible from the exterior S1 of the building.

  At night, the light source 20 emits light, and the light passes through the inside of the support 11 and the blindfold 10 and is emitted from the outward light exit 31 toward the outside S1 of the building. As a result, when viewed from the outside S1 of the building, the blindfold 10 is in a state of shining with high brightness, and even when the illumination is turned on inside the building S2, the inside S2 is difficult to see from the outside S1 of the building.

  According to the present embodiment, it is difficult to see the interior S2 from the exterior S1 of the building by emitting light from the outward light exiting portion 31 of the blindfold 10, and even if the interior S2 of the building is bright at night, sufficient A blindfold effect is obtained. Moreover, since the support body 11 and the blindfold body 10 are communicated and the light of the light source 20 of the support body 11 is incident on the plurality of blindfold bodies 10, the number of the light sources 20 is reduced. Thereby, the cost of the blindfold louver 1 can be reduced, and the number of replacements of the light source 20 is reduced, so that maintenance is also simplified.

  In the present embodiment, since the wall surface on the building interior S2 side of each blindfold body 10 is formed wider than the wall surface on the building exterior S1 side, the exterior S1 is easily visible from the interior S2 of the building. The inside S2 becomes difficult to see from S1, and the outside scenery becomes easy to see and a high blinding effect is obtained.

  Since the outgoing light portion 31 is set to have a higher reflectance with respect to the light incident from the outside of the blindfold 10 than the other portions of the blindfold 10, the blindfold 10 receives light from the outside S1 such as the sun. Reflection can improve the blinding effect during the day.

  Since the low brightness portion 40 is formed on the wall surface on the building interior S2 side of each blindfold body 10, when the exterior S1 is viewed from the interior S2 of the building, the blindfold body 10 has low brightness, and the blindfold 10 The outside S1 can be easily seen from the gap.

  In the above embodiment, as shown in FIGS. 6 to 8, the light from the light source 20 of the support 11 is emitted also to the wall surface on the building interior S2 side of each blindfold body 10, that is, the wall surface on the long side 10b side. An inward light emitting unit 60 may be provided. In such a case, the inward light emitting portion 60 is formed in a rectangular shape that is long in the vertical direction, like the outward light emitting portion 31. The inward light emitting portion 60 is formed of a milky white acrylic plate with high light diffusibility. Therefore, the light emitted from the light source 20 at the end of the support 11 travels while reflecting the inner surface 21 of the support 11, enters the blindfolds 10, and travels while reflecting the inner surfaces 30 of the blindfolds 10. The light is emitted from the inward light emitting portion 60 of each blindfold 10 to the inside S2 side of the building. As shown in FIG. 6, a part of the light emitted from the inward light emitting unit 60 passes through the window A and proceeds to the inside S2 side of the building, and a part of the light is reflected by the window A and passes through the gap of the blindfold 10. Proceed to the exterior S1 side of the building.

  As shown in FIG. 8, the inward light outgoing portion 60 is formed wider than the outward light outgoing portion 31. Further, in this case, the low luminance part 40 is formed on both sides of the inward light emitting part 60.

  According to such an example, since the light is emitted from the inward light emitting unit 60 to the inside S2 side of the building, the light of the blindfold louver 1 can be used as auxiliary illumination of the inside S2 of the building.

  In addition, since the blindfold 10 is arranged outside the window surface of the building, the light emitted from the inward light emitting portion 60 of the blindfold 10 is reflected by the window A. As a result, the interior S2 becomes more difficult to see from the exterior S1 of the building, and the blinding effect is further improved.

  Since the inward light emitting portion 60 is formed wider than the outward light emitting portion 31, more light is reflected on the window A, and as a result, the interior S2 is more difficult to see from the exterior S1 of the building.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  The blindfold 10 has a substantially trapezoidal cross-sectional shape, but may have another shape. For example, a semi-cylindrical shape may be used as shown in FIG. 9, or a square shape having the same width on the outside S1 side and the inside S2 side of the building as shown in FIG.

  Moreover, the shape of the outward light emission part 31 and the inward light emission part 60 is not restricted to a rectangular shape, Other shapes may be sufficient. The outward light exiting portion 31 and the inward light exiting portion 60 are continuous along the blindfold 10, but may be intermittently formed along the blindfold 10.

  The support 11 is provided at the upper and lower ends of the blindfold 10, but may be provided only at one end. Moreover, although the light source 20 was provided in the both ends of the support body 11, it may be provided only in the edge part of one side. Further, the light source 20 is not limited to the end of the support 11 and may be in the center, for example.

  Further, the blindfold louver 1 may be such that the plurality of blindfold bodies 10 are horizontal and the support body 10 is vertical. The blindfold louver 1 may be inside the window A. The blindfold louver 1 may be provided in an opening other than a window such as a doorway.
