In the former case, there is no particular problem, but when the latter louver fence is used, it is arranged by arranging the daylighting panel in an inclined manner to form a ventilation space. Depending on the form, the lower part and upper part of the upper and lower daylighting panels may overlap with the position of the sun, and when such an overlapping part with the sun occurs, this kind of daylighting panel is generally at the upper and lower ends. Because it is fixed to the vertical frame of the fence via the upper and lower horizontal rails, sunlight incident on the lower part of the upper daylighting panel will enter the lower daylighting panel. In many cases, sunlight refracts toward the upper horizontal beam, and the sunlight toward the upper horizontal beam is reflected or diffused by the upper horizontal beam and cannot reach the sunlight supply area.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a residential fence using a daylighting panel 10, and the housing fence A has a large number of daylighting panels vertically arranged between left and right vertical frames. Arranged in parallel, installed on the upright partition B and covered the upper part thereof, so that sunlight is refracted downward by the daylighting panel 10 and supplied to the back surface of the upright partition B. At this time, the daylighting panel 10 of the fence A is a solar refracting surface having a strong and weak refractive index composed of a number of belt-shaped refracting surfaces 12 and 16 for solar refraction, each having a different refractive index. In this example, the solar refracting surface group 11 having a weak refractive index is arranged on the upper side in the plane, and the solar refracting surface group 15 having a strong refractive index is arranged on the lower side or the lower end in the plane. The housing fence A is The vertical arrangement between the left and right vertical frames of the optical panel 10 is a louver arrangement that is inclined so as to form a ventilation space 21 that is separated from the upper and lower lighting panels 10 between the upper and lower ends. The solar light refracting surface group 15 having the refractive index is refracted downward toward the solar light refracting surface group 11 having a low refractive index in the lower daylighting panel 10 so that the solar light is refracted downward twice. It is.

  That is, the residential fence A is placed on and fixed to a standing partition B installed on the ground surface such as a block fence or a blind fence, or the lower end is partially overlapped and fixed to the back of the upper end. It is installed so as to stand up and protrude further upward from the partition B, and a shaded normal region formed by blocking sunlight on the surface of the back of the standing partition B, that is, a refracted light supply region a The sunlight is refracted by the sunlight refracting surface groups 11 and 15 having the above-mentioned strong and weak refractive index to reduce or eliminate the shade as much as possible, and the influence of the occurrence of the shade on the landscape and plant growth is possible. In the present example, sunlight is supplied to the refracted light supply region a mainly by the sunlight refracting surface group 11 having the weak refractive index, while in the upper daylighting panel 10. Sun of the refractive index group 15 having a strong refractive index Is directed downward toward the sunlight refractive surface group 11 of the lower refractive index of the lower daylighting panel 10 to perform the above-mentioned two downward refractions so that the sunlight with respect to the daylighting panel 10 is effectively transmitted to the refractive light supply region a as much as possible. The loss of solar light supply of the daylighting panel 10 is minimized.

  In this example, the daylighting panel 10 of the residential fence A has a fence or a transparent synthetic resin extruded plate obtained by extruding a highly weather-resistant transparent resin such as acrylic or polycarbonate, for example, to ensure rigidity for the fence. However, at this time, the daylighting panel 10 has the weak refractive index solar refracting surface group 11 with a band width of 1 mm or more and 5 mm or less on each band-like refracting surface 12. In addition, the total band width of the band-shaped refracting surface 12 and the light-transmitting narrow band surface 13 is set to 2 mm or more and less than 20 mm.

  That is, the daylighting panel 10 has the above-described sunlight refractive surface groups 11 and 15 having the above-mentioned strong and weak refractive indices arranged on the front side facing the sun side, and the back side facing the site side is a flat surface, for example, 10 to 15 cm. In this example, the solar light refracting surface groups 11 and 15 have two refractive indexes, which are strong and weak, in this example. Among them, the solar refractive surface group 11 having a weak refractive index is mainly disposed in most of the in-plane of the daylighting panel 10, while the solar refractive surface group 15 having a strong refractive index is sub-arranged from the lower side to the lower end in the plane. The weak refractive index solar refracting surface group 11 in the example is set to 2/3, 3/4 to 4/5 above and below the in-plane of the daylighting panel 10, and the remaining solar refracting surface group 15 having a strong refractive index is left. It is arranged.

  The solar refracting surface groups 11 and 15 each have a plurality of strip-shaped refracting surfaces 12 and 16 for solar light refraction, and the weak refractive index solar refracting surface group 11 of the present example includes the respective strip-shaped refracting surfaces. It is assumed that the light transmission thin strip surface 13 is provided above 12, and in the solar light refraction surface group 11 of the weak refractive index, the belt-like refraction surface 12 is made concave toward the sun. While projecting to the front so as to form a curved lens surface, the light-transmitting narrow band surface 13 forms a plane parallel to the flat back surface, and the band-shaped refracting surface 12 of this example is The curved surface has a radius of curvature of several mm, for example, 4 mm, and a band width of 3 to 4 mm. The upper light-transmitting thin band surface 13 has a band width of about 1 to 5 mm, for example, 1 .5 mm width, and at this time, the light transmission thin strip surface 3 the total band width of the band refractive surface 12, of less than 20mm above the 2mm which, for example, as a 5mm width. The band-shaped refracting surface 12 protrudes to the front side by the radius of curvature, so that the band-shaped refracting surface 12 is located between the lower end of the light-transmitting fine band surface 13 and the light-transmitting thin band surface 13 below, and has a V-shaped cross section. As a result, the projecting dimension is made as small as possible by restricting the radius of curvature to the above several mm, and in this example, for example, it is suppressed to about 1 mm. The daylighting panel A is a thin wall having a maximum thickness of about 3 mm or less, for example, about 2.5 mm, even if the thickness of the light transmission thin strip surface 13 portion is about 1 to 2 mm, for example, 1.5 mm, from the rear surface. It is supposed to be a thing. At this time, between the lower end of each band-shaped refracting surface 12 having a V-shaped cross section and the upper end of the light transmitting thin band surface 13, for example, an inclined connecting surface 14 is provided so as to connect them in a straight line. In the example, the inclination angle of the inclined connecting surface 14 is, for example, about 30 degrees. Therefore, as long as the angle of the sun exceeds the angle of 30 degrees, the inclined connecting surface 14 can also Sunlight can be supplied toward the back surface.

  In the solar refractive surface group 11 having a weak refractive index, the total band width of the band-shaped refractive surface 12 and the light-transmitting narrow band surface 13 can be 2 to 20 mm, preferably 3 to 10 mm. If the total band width is 20 mm, the protruding dimension of the band-shaped refracting surface 12 is close to 4.5 mm, the maximum thickness of the daylighting panel 10 is increased to about 6 mm, and the curvature radius of the curved lens surface used for this is increased. As a result, the angle of refraction supply of sunlight becomes a loose angle, which is not suitable for reducing or eliminating the shade on the back of the standing partition B, and when it is less than 2 mm, the daylighting panel 10 is produced. Although the width of the band-shaped refracting surface 12 and the light transmitting surface 13 is too fine and these form a V-shaped groove, the surface of a fence to be installed outdoors is dusty. Is attached and installed Depending on the situation, dirt such as generation of flaws and the possibility of poor solar power supply due to this is likely to occur, and it is not suitable as well. Therefore, considering the possibility of fouling such as dust adhesion and generation of wrinkles, the belt-like refractive surface 12 And the light transmission thin strip surface 13 as a unit, the arrangement pitch is 3 mm or more, more preferably 4 mm or more.

  The band width of the light-transmitting thin strip surface 13 can be 1 mm or more and 5 mm or less, but if it exceeds 5 mm, the blinding action of the light-transmitting thin strip surface 13 is impaired, and the perspective of the road or a neighboring house is not visible. In order to invite the possibility, it is not suitable as a fence for a house that is also installed at the boundary with a road or a neighboring house, and if it is less than 1 mm, the total amount of sunlight transmitted by the light transmission thin strip surface 13 is insufficient. The above-described difference in brightness tends to cause a tendency to deteriorate the uniformity of sunlight supply, which is also not suitable. Therefore, in consideration of the blinding action and the uniformity of the sunlight supply, it is preferable that the band width of the light transmission thin strip surface 13 is 1.5 mm or more and 4 mm or less.

  On the other hand, the band-like refracting surface 16 in the high refractive index solar refracting surface group 15 is projected in the same manner so as to form an inclined lens surface so as to form a prism toward the sun. In this example, the band-shaped refracting surface 16 has the same or substantially the same projecting dimension as the band-shaped refracting surface 12 in the weak refractive index solar light refracting surface group 11, for example, about 1 mm. In this case, the band-shaped refracting surface 16 has an inclination angle of 30 to 40 degrees, in this example, about 35 degrees. Similarly to the sunlight refractive surface group 11 having the weak refractive index, the inclined connecting surface 17 having the same angle, for example, 30 degrees, is disposed on the back surface, and similarly, as long as the sun angle exceeds the 30 degree angle. , By the inclined connecting surface 17 Even are as capable sunlight supply toward the back surface of the upright partition member B.

  The lighting panel 10 formed in this manner has upper and lower horizontal beams 20 arranged at upper and lower ends via holders such as gaskets (not shown) that hold the upper and lower ends inclined, and the upper horizontal beams 20 are connected to a wide vertical frame. The frame is displaced to the site side, the lower horizontal beam 20 is displaced to the sun side, that is, the road or the adjacent land side, and the upper and lower horizontal beams 20 are fixed so as to be at the same height position of the vertical frame. A large number of daylighting panels 10 are disposed in an inclined manner within a frame of, for example, an aluminum extruded material, and the ventilation space 21 is formed between the daylighting panels 10, so that the housing fence A having the louver arrangement, that is, the daylighting louver fence. This is fixed such that the standing partition B is located on the upper surface of the standing partition B, for example, and sunlight is supplied to the back surface.

  In other words, the daylighting panel 10 of the present example in the residential fence A has a band-shaped refracting surface 12 in the solar refractive surface group 11 of the weak refractive index of the main arrangement, so that the sunlight enters the refracted light supply region a. On the other hand, the light is refracted downward and supplied, and the shade on the back surface of the standing partition B is eliminated. On the other hand, the light-transmitting narrow band surface on the band-shaped refractive surface 12 of the solar refractive surface group 11 having the weak refractive index is provided. 13 transmits and supplies sunlight to the transmitted light supply area b on the back surface, which produces a difference in brightness and darkness from the direct light irradiation area c by direct light passing through the daylighting panel 10. By eliminating as much as possible, it is possible to make the illuminance of the shade elimination between the refractive light supply region a and the transmitted light supply region b of the sun as uniform as possible, and the strong refractive index of the sub-arrangement The band-shaped refracting surface 16 in the sunlight refracting surface group 15 is: Sunlight is applied to the band-shaped refracting surface 12 of the sunlight refractive surface group 11 having a low refractive index of the daylighting panel 10 positioned at the upper position, particularly the band-shaped refracting surface 12 positioned at the upper part in the plane, avoiding the horizontal beam 20. Refracting downward and supplying the light, the band-shaped refracting surface 12 of the lower daylighting panel 10 refracts the sunlight again downward and refracts twice, thereby supplying the refracted light supply region a. In the upper daylighting panel 10 that is assumed when supplementary sunlight is supplied to the back surface of the upright partition B and the strip-shaped refracting surface 12 having the same refractive index is disposed on the entire daylighting panel 10. The lower refracted light is directed to the upper horizontal beam 20 of the lower daylighting panel 10, and the loss of sunlight due to the upper horizontal beam 20 reflecting and diffusing it is minimized or eliminated. Each inclined connecting surface 17 Is as for supplying sunlight when the position of the sun is below the angle.

  At this time, the daylighting panel 10 imparts a light diffusing action thereto, thereby reducing the intensity of sunlight supplied from the daylighting panel 10 to the refractive light supply region a and the transmitted light supply region b. The glare in a and b and the glare caused by this can be reduced, and the measure of the light diffusing action is performed by irregularly reflecting the emitted light by using the panel surface of the daylighting panel 10, for example, the back surface as a mat surface. A diffused reflection material such as a pigment or a bead is added to the daylighting panel 10 so that the sunlight is supplied from the refracted light supply area a to the transmitted light supply area b in this example by colored light or irregularly reflected light. can do. By taking measures for the light diffusing action in this way, it is possible to further reliably inhibit the see-through of the light transmitting narrow strip surface 13 at the same time and to secure a high level of blinding action as the residential daylight fence A. .

  In this example, the daylighting panel 10 is provided with the light diffusing action, and the light diffusing action is due to a measure that uses all or part of the rear surface of the daylighting panel 10 as a matte surface. This is done by subjecting the daylighting panel 10 that has been extruded or cut to a predetermined size to a physical or chemical matting process such as shot blasting or etching in accordance with a conventional method.

  The height of the house fence A using the daylighting panel 10 of this example can be set as appropriate. For example, it is about 30 cm, that is, two or three daylighting panels 10 are arranged in parallel. Even in the position directly below the back of the standing partition B, some shade area remains, but the shade can be greatly reduced to refract and supply sunlight to most of the sunlight. It is possible to reduce glare and glare caused by this, and to make the sunlight softer, while ensuring a high degree of blinding action by completely blocking the see-through from the road or the adjacent ground.

  Although the illustrated example is as described above, the daylighting panel is made of glass or a transparent resin other than the above, and the solar refractive surface group having strong and weak refractive index is changed in a stepwise manner. It is composed of a large number of refractive index belt-like refractive indexes, and the solar refractive surface group having the strongest refractive index is arranged at the lower or lower end in the plane, and the lighting panel is arranged above and below the horizontal beam fixed to the fence vertical frame.
