Description

  The present invention relates to a closing member and a daylighting member that incorporate light such as sunlight into a building.

2. Description of the Related Art Conventionally, a technique is known in which light such as sunlight incident through an opening of a building is emitted in a desired direction so as to collect light inside the building (for example, Patent Document 1).
The daylighting sheet of Patent Document 1 has a light deflection layer that deflects light, and deflects light incident obliquely from above, such as sunlight, in a specific direction and enters the inside of the building. Natural light can be used to brighten the room without using a lighting device, etc., enabling energy saving (reducing lighting costs) and creating a comfortable indoor space.
However, since such a daylighting member simply takes light such as sunlight into the room, it is poor in design.For example, when it is used in a kindergarten classroom or a hospital room, the daylighting room is sufficient. In some cases, it was not possible to make it comfortable.

FIGS. 3 (e) and 3 (f) are also photographs in the case where a daylighting member of another comparative example is attached to a window, which were taken at 11:30 am and 2:00 pm, respectively.
In the present embodiment, the daylighting member shows an example in which light such as sunlight is taken inside the building (indoor side), but light may be taken into the indoor side of the vehicle.

As shown in FIGS. 1A and 1B, the closing member 10 is a daylighting window installed in an opening 2 provided on the wall of the building 1, and includes a window frame 11, a window 12 and a daylighting member 20.
The window frame 11 is a frame member that fixes the window 12 to the opening of the building, and is formed of a metal such as aluminum, for example.
The window 12 is a transparent glass substrate that closes the opening 2 of the building 1.
The daylighting member 20 is a sheet-like member that introduces light such as sunlight into the inside of the building (inside the room), and as shown in FIG. 2A, on the + Y side of the window 12 (inside the building). Affixed to the surface. As shown in FIG. 1B, the daylighting member 20 includes a plurality of light transmission parts 21 and a light deflection part 30.

As shown in FIGS. 2B and 2C, the light transmitting portion 21 is a portion that transmits the light incident on the daylighting member 20 through the window 12 as it is to the indoor side. In the present embodiment, It is an air gap (air layer) provided between adjacent light deflection units 30.
As shown in FIG. 2A, the light deflection unit 30 is a part that deflects the light incident on the daylighting member 20 through the window 12 and takes it into the inside of the building (inside the room). Affixed via the bonding layer 22 along the inner (−Y side) surface of the object.

As shown in FIG. 1B, each of the light transmitting portion 21 and the light deflecting portion 30 is formed in a strip shape extending in the first direction, and stripes in the second direction intersecting the first direction. Are arranged alternately. Here, the first direction means not only a direction parallel to the vertical direction (Z direction) but also includes a direction inclined in a range of −80 ° to + 80 ° with respect to the vertical direction. From the viewpoint of more clearly reflecting the shape, it is preferably in the range of −60 ° to + 60 ° with respect to the vertical direction, more preferably in the range of −45 ° to + 45 ° with respect to the vertical direction. Is more preferably in the range of −30 ° to + 30 °. In the present embodiment, the first direction is a direction parallel to the vertical direction (Z direction), and the second direction intersecting the first direction is a direction parallel to the left-right direction (X direction). It explains as being.
Thus, by providing the daylighting member 20 in which the light transmitting portion 21 and the light deflection portion 30 are arranged in a stripe shape on the indoor side (+ Y side) surface of the window 12, the daylighting member 20 has the opening 2. The light such as sunlight entering from can be taken in a stripe shape. As a result, as shown in FIGS. 3 (a) and 3 (b), the daylight is reflected in stripes on the ceiling or wall of the room, and the daylighting member 20 has a pleasant design. The lighting function with a feeling can be exhibited and the indoor environment can be made comfortable.

As shown in FIGS. 3C and 3D, the light transmission part and the light deflection part are each formed in a strip shape extending in the second direction (X direction), and the first direction (Z If the light beams are alternately arranged in the (direction) direction, the lights collected from the light deflecting units are mixed with each other, and the pattern of the light reflected on the ceiling of the room becomes unclear and the design is deteriorated.
Also, as shown in FIGS. 3 (e) and 3 (f), when the light deflecting portion is formed in a circular shape and is randomly arranged on the indoor surface of the window, each light deflecting portion is Since the daylights are mixed with each other, the pattern of the light reflected on the ceiling of the room becomes unclear and the design is deteriorated.
Therefore, the light transmission part 21 and the light deflection part 30 are formed in a strip shape extending in the first direction (vertical direction, Z direction), and are alternately arranged in stripes in the second direction (left-right direction, X direction). It is desirable that

Here, the daylighting member 20 has the widths S1 and S2 in the second direction (left-right direction) of the light deflection unit 30 and the light transmission unit 21 to be 50 mm or more and 300 mm or less in order to achieve the above-described effect more effectively. It is desirable to be formed. If the width S2 of the light transmission part 21 is less than 50 mm, the distance between the adjacent light deflection parts 30 becomes too close, and the light taken in by each light deflection part 30 is likely to be mixed, and the ceiling in the room It is not desirable because the light pattern adopted in the area is not easily recognized as a stripe pattern. In addition, when the width S2 of the light transmitting portion 21 is larger than 300 mm, the distance between the adjacent light deflecting portions 30 is too large, and the light pattern taken in the indoor ceiling or the like is not easily recognized as a stripe shape. So undesirable.
Further, if the width S1 of the light deflection unit 30 is less than 50 mm, the width of the light deflection unit 30 becomes too narrow, and the light pattern taken on the indoor ceiling or the like is not easily recognized as a stripe shape. Or the amount of light taken in by the light deflection unit 30 is reduced, which is not desirable. Further, when the width S1 of the light deflection unit 30 is larger than 300 mm, the width of the light deflection unit 30 becomes too thick, and it is difficult to recognize the light pattern taken into the indoor ceiling or the like as a stripe shape. Absent.

The light deflection unit 30 is located on the outer side (−Y side) of the building in the thickness direction (Y direction), is opposed to the incident surface 30a on which light such as sunlight is incident, and the incident surface 30a. It is located on the inner side (+ Y side) of the object and is composed of an emission surface 30b from which light is emitted.
As shown in FIG. 2A, the light deflection unit 30 includes a base portion 31 having a plurality of grooves 31a and a louver portion 32 formed in the grooves 31a. The light L such as sunlight mainly incident from the side) is deflected in a predetermined direction by the interface between the base portion 31 and the louver portion 32 and is emitted toward the inside of the building.
Note that the haze value of the exit surface 30b of the light deflection unit 30 is 50% or less from the viewpoint of suppressing the diffusion of light taken into the indoor ceiling or the like and blurring of the stripe pattern. It is desirable that it is 10% or less.

The base portion 31 is a member that is the basis of the light deflection portion 30 formed of a transparent material having light transmittance. A plurality of grooves 31 a are arranged in the base portion 31 in the left-right direction (X direction) and in the vertical direction (Z direction) along the incident surface 30 a of the light deflection unit 30.
The louver part 32 is formed of a light transmissive material in a groove 31 a provided in the base part 31. The louver portion 32 extends in the left-right direction (X direction), and a plurality of louver portions 32 are arranged in the vertical direction (Z direction) along the incident surface 30 a of the light deflection unit 30.

  The louver portion 32 is formed in a wedge shape in cross section (YZ cross section) parallel to the arrangement direction (vertical direction (Z direction)) and parallel to the thickness direction (Y direction) of the light deflection section 30. Has been. Here, the wedge shape refers to a shape in which one end portion is wide and gradually becomes narrower toward the other, and includes a triangular shape, a trapezoidal shape, and the like. The louver part 32 is formed so that the width on the incident surface 30a side is wide and the width is gradually narrowed toward the exit surface 30b side. The louver portion 32 of the present embodiment is formed in a substantially triangular shape with a cross-sectional shape having the base surface on the incident surface 30a side.

By forming the louver part 32 in this way, light L such as sunlight that has entered the daylighting member 20 from the vertically upper side (+ Z side) is mainly generated by the louver part 32 as shown in FIG. The light enters the inclined surface on the vertical upper side (+ Z side), is reflected at the interface between the base portion 31 and the louver portion 32, is deflected, and is emitted from the emission surface 30b.
The refractive index of the louver part 32 is preferably formed to be smaller than the refractive index of the base part 31 from the viewpoint of efficiently reflecting light such as sunlight at the interface between the base part 31 and the louver part 32. Therefore, it is desirable that the louver part 32 be formed of a material having a refractive index lower than that of the base part 31. Further, the louver portion 32 may empty the air layer, that is, the groove 31a.

  Moreover, in order to improve the reflectance, a reflective surface may be formed on the interface between the louver part 32 and the base part 31 with a material having a high reflectance such as a metal-containing compound such as aluminum or aluminum oxide. . Furthermore, when a reflective surface is formed, the same material may be used for the louver portion 32 and the base portion 31. Thereby, the refractive index of the louver part 32 and the refractive index of the base part 31 can be made substantially the same, and the refraction at the interface between the louver part 32 and the base part 31 can be suppressed. be able to.

Note that the light deflection unit 30 may be provided with a coloring unit that colors light that is introduced indoors on either the entrance surface 30a or the exit surface 30b. Moreover, you may make it provide a colored part in a part or all of the base part 31 instead of providing a colored part in the entrance plane 30a or the output surface 30b. Thereby, the light taken in indoor can be colored according to indoor space, and the design property can further be improved.
This colored portion can be formed into a sheet-like form made of a resin containing a pigment or dye of a desired color, for example, and is attached to the entrance surface 30a or the exit surface 30b of the light deflection unit 30. Can be. Further, the colored portion can be provided in a part or all of the base portion 31 of the light deflection portion 30 by causing the resin constituting the base portion 31 to contain a pigment or dye of a desired color.
Note that at least a part of the colored portion provided in the light deflecting portion may be colored with a color different from that of the colored portions provided in the other light deflecting portions. By doing in this way, the light of the several color will be taken in by the lighting member 20, and the design property can further be improved.

FIG. 4 is a diagram showing another form of the light deflection unit, which is a cross-sectional shape in the YZ section of the light deflection unit.
The light deflecting unit 30 has been described as an example including the base unit 31 and the louver unit 32. However, the present invention is not limited to this, and incident light may be deflected by a different configuration.
For example, as shown in FIG. 4A, the light deflecting unit 30 has a configuration in which the base portion and the louver portion described above are formed of the same material, and the reflective layer 34 is sandwiched and connected, that is, a member 33 serving as a base. A flat reflection layer 34 extending in the left-right direction (X direction) and inclined at a predetermined angle with respect to the normal direction of the incident surface 30a along the incident surface 30a of the light deflection unit 30 is formed in the vertical direction ( A plurality may be arranged in the (Z direction). In this case, the reflective layer 34 is formed of a material having a high reflectance such as a metal-containing compound such as aluminum or aluminum oxide.
Further, as shown in FIG. 4B, the light deflecting unit 30 may have a configuration in which a plurality of prism bodies 30c are arranged in the vertical direction (Z direction) along the incident surface 30a. Moreover, it is good also as a form which forms a Fresnel lens shape instead of forming a prism body.

The bonding layer 22 is a layer that detachably bonds the light deflection unit 30 to the window 12, and is provided on a surface (incident surface 30 a) on the −Y side of the light deflection unit 30. By detachably joining the light deflection unit 30 to the window 12 in this manner, the light deflection unit 30 can be attached or removed from the window 12 as necessary, and the indoor environment can be easily adjusted. can do.
The bonding layer 22 is made of, for example, an adhesive that can be peeled and reattached, an electrostatic adsorbent, or the like. As the adhesive, those that can be peeled off from the adherend even after being attached to the adherend, and can be attached to the adherend again after being peeled off, for example, silicone polymer, urethane polymer, acrylic polymer, An adhesive such as rubber can be used. In addition, as the electrostatic adsorbent, those that can be adsorbed to the adherend by the electrostatic charge held inside are preferable. For example, plastics such as polyolefin, polyamide, polyester, polycarbonate, and polystyrene have high insulating properties and are electrostatic. Since it is easy to hold an electric charge inside, it can be preferably used. In addition to the above-described materials, known materials can be appropriately used for the adhesive and the electrostatic adsorbent.

  From the viewpoint of avoiding light refracting between the light deflection unit 30 and the window 12, the bonding layer 22 prevents the air deflection unit 30 and the window 12 from interposing an air layer between the light deflection unit 30 and the window 12. It is desirable to join. Therefore, the bonding layer 22 is provided with, for example, the above-described adhesive having translucency over the entire incident surface 30a (the surface on the -Y side) of the light deflector 30, so that no air layer is interposed therebetween. The deflection unit 30 is joined to the window 12.

Moreover, you may make it the joining layer 22 be comprised with a magnet. In this case, the bonding layer 22 is provided at, for example, the upper edge and the lower edge of the light deflection unit 30, and uses a magnetic member for the window frame 11 or arranges a magnetic member in a part of the window frame 11 to deflect the light. The light deflection unit 30 can be joined to the window 12 by attracting the portion 30 to the window frame 11 by magnetic force.
Note that, from the viewpoint of avoiding that an air layer is interposed between the light deflection unit 30 and the window 12 and the light is refracted, the bonding layer 22 includes the surface on the + Y side of the window 12 and the − of the light deflection unit 30. It is desirable that the surface on the Y side (incident surface 30a) be closely bonded without any gap.
As described above, the bonding layer 22 is bonded to the window 12 by the magnetic force, so that the bonding layer 22 is formed from the window 12 of the light deflection unit 30 as compared with the bonding layer formed of the above-described adhesive or the like. Can be attached and detached more easily.

  Note that the bonding layer 22 may be omitted. For example, after the light deflecting unit 30 and the window 12 are brought into close contact with each other using water, the light deflecting unit 30 and the window 12 can be directly and detachably joined by evaporating water. In addition, when the surface of the light deflection unit 30 or the window 12 exhibits adhesiveness or electrostatic adsorption, the light deflection unit 30 and the window 12 can be directly and detachably fixed. As a specific example, the light deflection unit 30 in which a layer containing the above-described pressure-sensitive adhesive or electrostatic adsorbent is arranged on the outermost surface (incident surface 30a) side can be cited.

Next, another embodiment of the daylighting member 20 will be described.
FIG. 5 is a diagram illustrating another embodiment of the daylighting member. Fig.5 (a) is the front view seen from the thickness direction of the lighting member. FIG. 5 (b) is a diagram showing a cross section b of the daylighting member of FIG. 5 (a), FIG. 5 (c) is a diagram showing a section c of the daylighting member of FIG. 5 (a), FIG.5 (d) is a figure which shows the d section cross section of the lighting member of Fig.5 (a).

In the above description, the example in which the daylighting member 20 is configured by the light deflection unit 30 and the light transmission unit 21 including a gap provided between the adjacent light deflection units 30 has been described, but the present invention is not limited thereto. Not a thing.
As shown in FIG. 5, in the daylighting member 20, the light transmitting portion 21 is configured by a light-transmitting member (for example, a transparent resin), and the light transmitting portions 21 and the light deflecting portions 30 are alternately arranged. Alternatively, it may be in the form of a single sheet-like member. In this case, as in the embodiment shown in FIG. 1B, the strip-shaped light deflecting portions 30 are not attached to the window 12 one by one, but the daylighting member 20 is placed in the window 12 as a single sheet. It can be affixed to the inner (+ Y side) surface, and the operation of peeling and reattaching the daylighting member 20 to the window 12 can be facilitated.

Next, another form of the stripe pattern formed by the light transmission part 21 and the light deflection part 30 constituting the daylighting member 20 will be described.
FIG. 6 is a diagram showing another form of the light transmitting part and the light deflecting part constituting the daylighting member. Each drawing of FIG. 6 is a front view of the daylighting member as seen from the thickness direction (Y direction).
The light transmitting part 21 and the light deflecting part 30 are not limited to the form shown in FIG. 1B as long as they are formed in a strip shape extending in the first direction. Here, the belt-like shape extending in the first direction is not only the straight belt-like shape extending in the vertical direction shown in FIG. 1B, but also the wave shape having the first direction as the traveling direction, This refers to a shape including a linear shape inclined within an angle range of 1 direction (−80 ° to +80 with respect to the vertical direction) and a curved shape such as a wave shape.

For example, as shown in FIG. 6A, the light transmission part 21 and the light deflection part 30 are formed in a wave shape, and the traveling direction P of the wave shape is in the first direction (vertical direction, Z direction). The light transmitting portions 21 and the light deflecting portions 30 may be alternately arranged in a stripe shape in the second direction (left-right direction, X direction).
Further, as shown in FIG. 6B, the extending direction of the band-like shapes of some of the light deflection units and the light transmission units may be inclined at a predetermined angle θ with respect to the vertical direction. In this case, the angle θ of each light deflection unit and each light transmission unit needs to be formed within the above-described angle range in the first direction (−80 ° to + 80 ° with respect to the vertical direction). Note that the angles θ of the light deflecting units and the light transmitting units may be different from each other, or may be the same.
Furthermore, as shown in FIG. 6C, the light transmitting portion 21 and the light deflecting portion 30 may be formed in a shape in which a belt-like shape extending in the first direction is curved in a “<” shape. In this case, the angle θ1 and the angle θ2 of each line segment bent in a “<” shape of the light transmitting portion 21 and the light deflecting portion 30 are within the angle range (−80 ° to + 80 °) in the first direction described above. Need to be formed.
Even if it is the above form, the light taken in by the light deflecting unit 30 on the ceiling or the like in the room is reflected in a stripe shape, and the design can be further improved.

As described above, in the daylighting member 20 (closing member 10) of the present embodiment, the light deflection unit 30 and the light transmission unit 21 are formed in a strip shape extending in the first direction (vertical direction, Z direction). They are alternately arranged in a second direction (left-right direction, X direction) that intersects (orthogonally) the direction. As a result, the daylighting member 20 can sufficiently incorporate light such as sunlight into the indoor side, and can reflect the light taken in by the light deflecting unit 30 onto the ceiling or wall of the room in a striped manner. A daylighting function with a rich sense of fun can be demonstrated.
In addition, the daylighting member 20 (closing member 10) of the present embodiment has the widths S1 and S2 in the second direction (left-right direction) of the light deflection unit 30 and the light transmission unit 21 are 50 mm or more and 300 mm or less. The above-described effects can be achieved efficiently.
Further, in the daylighting member 20 (closing member 10) of the present embodiment, at least a part of the light deflection unit 30 and the light transmission unit 21 formed in a band shape is curved in the second direction (left-right direction, X direction). In this case, it is possible to further improve the design of the light pattern that is adopted on the indoor ceiling or the like.

(Second Embodiment)
FIG. 7 is a diagram showing details of the daylighting member of the second embodiment, and is a front view of the daylighting member as seen from the thickness direction.
In the following description and drawings, parts having the same functions as those of the first embodiment described above are denoted by the same reference numerals or the same reference numerals at the end (last two digits), and repeated descriptions are omitted as appropriate. To do.

As shown in FIG. 7A, the daylighting member 120 (closing member) of the present embodiment is different from that of the first embodiment in that the light transmitting part 121 and the light deflecting part 130 are different. It is different from the member 20 (closing member).
The daylighting member 120 is a sheet-like member that takes light such as sunlight inside the building (inside the room), and is attached to the surface of the window 12 on the + Y side (inside the building). The daylighting member 120 includes a plurality of light transmission parts 121 and a light deflection part 130.
As shown in FIG. 7A, the light deflecting unit 130 of the present embodiment is formed by a plurality of specific shapes, and the specific shapes are in the first direction (vertical direction, Z direction in the present embodiment). It is arranged in an extending strip shape. The daylighting member 120 of the present embodiment has a second direction (in this embodiment, left and right direction, X direction) in which the light deflection unit 130 in which the specific shape is arranged in a band shape intersects the first direction with the light transmission unit 121 interposed therebetween. Are arranged alternately at predetermined intervals.
Here, the specific shape means not only a circle, an ellipse, and an ellipse, but also a shape including a polygon such as a triangle and a rectangle, and a pattern such as an animal or a character. In the present embodiment, an example in which the light deflection unit 130 is formed in a circular shape as a specific shape will be described.
Moreover, the specific shape being arranged in a strip shape extending in the first direction is not only the case where the specific shape is arranged in a straight line extending in the vertical direction, but also a wave shape having the first direction as the traveling direction. Or what includes the case where it arranges in the linear form which inclined in the angle range (-80 degree- + 80 degree with respect to a perpendicular direction) of the above-mentioned 1st direction, or the curved shape.

The light deflection unit 130 has a distance between specific shapes adjacent in the second direction (left-right direction) as d1, and a distance between specific shapes adjacent in the first direction (vertical direction) as d2. The distance d1 is formed to be larger than the distance d2 (d1> d2), and the distance d1 is formed in a range of 50 mm to 300 mm.
Here, the distance d1 between specific shapes refers to the shortest distance between specific shapes adjacent in the second direction in the second direction. Further, the distance d2 between the specific shapes refers to the shortest distance between the specific shapes adjacent to each other in the first direction in the first direction.
Thus, by setting the magnitude relationship between the distance d1 and the distance d2 to be d1> d2 and defining the dimension range of the distance d1 as described above, the light deflection unit 130 in which the specific shape is arranged is arranged in the first direction (vertical It can be seen as a strip extending in the direction) or a strip-like shape, and the light deflector 130 can appear as stripes alternately arranged in the second direction (left-right direction) with the light transmitting portion 121 interposed therebetween.
As a result, the light taken into the room by the daylighting member 120 is reflected in a striped pattern on the ceiling or wall of the room, and the daylighting member 120 exhibits a daylighting function with a sense of fun that is rich in design. The indoor environment can be made comfortable.

If the relationship between the distance d1 and the distance d2 is d1 ≦ d2, the light deflection unit is difficult to recognize as a strip extending in the first direction (vertical direction), while in the second direction (left-right direction). It becomes easy to look like an elongated strip. For this reason, when viewed as the whole daylighting member, the light deflection section appears as stripes arranged alternately in the first direction (vertical direction) across the light transmission section (FIG. 3 (c), FIG. 3). (See (d)), the pattern of light reflected on the ceiling or the like of the room tends to become unclear, and the design is deteriorated.
In addition, when the distance d1 is less than 50 mm, the distance between the light deflection units 30 adjacent in the second direction (left-right direction) becomes too short, and the pattern of light taken into the indoor ceiling or the like is striped. It is not desirable because it becomes difficult to be recognized as. When the distance d1 is larger than 300 mm, the distance between the light deflecting units 130 adjacent in the second direction (left-right direction) becomes too long, and the light pattern taken into the indoor ceiling or the like is recognized as a stripe pattern. It is not desirable because it becomes difficult to be done.

The width S3 in the second direction (left-right direction) of the specific shape of the light deflection unit 130 is desirably formed in the range of 50 mm to 300 mm. Here, the width S3 of the specific shape refers to the maximum dimension of the specific shape in the second direction.
If the width S3 in the second direction (left-right direction) of the specific shape is less than 50 mm, the light deflecting unit 130 becomes too small with respect to the light transmitting unit 121, and the light taken into the indoor ceiling or the like. This is not desirable because it is difficult to be recognized as a stripe pattern, or the amount of light taken in by the light deflecting unit 130 is reduced. On the other hand, when the width S3 is larger than 300 mm, the light deflecting unit 130 becomes too large, and the light pattern taken in the indoor ceiling or the like is not easily recognized as a stripe shape, which is not desirable.
In the above description, the specific shapes of the light deflection unit 130 are all formed in the same shape. However, the present invention is not limited to this example. As long as the numerical range of the width S3 (in the direction of 2) (from 50 mm to 300 mm) and the numerical range of the distance d1 (from 50 mm to 300 mm) are satisfied, the sizes and shapes of the specific shapes may be different. Also, as the specific shape, not only a circular shape but also different shapes such as an ellipse, a polygonal shape, and a character pattern may be mixed.

As described above, in the daylighting member 120 (closing member) of the present embodiment, the light deflection unit 130 or the light transmission unit 121 is formed in a specific shape, and the specific shape is in a strip shape extending in the first direction (vertical direction). The light deflection units 130 arranged in a specific shape in a strip shape are alternately arranged in the second direction (left-right direction) with the light transmission unit 121 interposed therebetween. As a result, the daylighting member 120 can sufficiently incorporate sunlight and other light into the room side, and can also reflect the light taken in by the light deflecting unit 130 on the ceiling or wall of the room in a striped manner. A daylighting function with a rich sense of fun can be demonstrated.
In the daylighting member 120 (closing member) of the present embodiment, the distance d1 of the specific shape adjacent in the second direction (left-right direction) is greater than the distance d2 of the specific shape adjacent in the first direction (vertical direction). Since the width in the second direction (left and right direction) of the specific shape is 50 mm or more and 300 mm or less, the above-described effects can be achieved more efficiently. Can do.

Next, another embodiment of the daylighting member 120 of this embodiment will be described.
FIG. 8 is a diagram illustrating another embodiment of the daylighting member 120. Each drawing of FIG. 8 is a front view of the daylighting member as seen from the thickness direction.
In the daylighting member 120, as shown in FIG. 8A, the light transmitting portion 121 is formed by a plurality of specific shapes, and the specific shapes are arranged in a strip shape extending in the first direction (vertical direction, Z direction). You may make it do. In this case, the daylighting members 120 are alternately arranged at predetermined intervals in the second direction (left and right direction, X direction) so that the light transmitting parts 121 in which the specific shapes are arranged in a band shape sandwich the light deflection part 130. In other words, the light transmitting unit and the light deflecting unit shown in FIG. 7 are interchanged.

Further, at least a part of the light deflection unit 130 in which the specific shape is arranged in a strip shape extending in the first direction (vertical direction) may be curved in the second direction (left-right direction, X direction). For example, as shown in FIG. 8B, the light deflection unit 130 in which the specific shape is arranged in a band shape is formed in a wave shape, and the traveling direction P of the wave shape coincides with the first direction. For example, the light deflection units 130 formed in this wave shape so as to coincide with the vertical direction may be alternately arranged in the second direction (left-right direction) with the light transmission unit 121 interposed therebetween. Good.
The wave-shaped traveling direction P may be inclined with respect to the vertical direction as long as it is within the angle range of the first direction (−80 ° to + 80 ° with respect to the vertical direction).

Furthermore, as shown in FIG. 8 (c), not only circular shapes, but also triangles, polygons such as rectangles, cards such as playing cards (spades, hearts, clubs, diamonds) are mixed, Each of the specific shapes having different sizes is formed in the shape of the light deflector 130 arranged in a wave shape, and the angle θ3 of the wave shape traveling direction P with respect to the vertical direction is within the range of the first direction (vertical). -80 ° to + 80 ° with respect to the direction).
Even in the above-described form, the light taken into the indoor ceiling or the like by the light deflector 130 is reflected in a stripe shape, and the design can be further improved. In particular, as shown in FIG. 8 (c), the specific shape constituting the light deflector 130 is formed in a plurality of different shapes and sizes, thereby greatly improving the design of light that can be taken into the indoor ceiling or the like. Can be improved.
8B and 8C can also be configured such that the light transmission unit 121 and the light deflection unit 130 are interchanged.

  8A to 8C, the distance d1 between the specific shapes adjacent to each other in the second direction (left and right direction, X direction) is the same as in the form shown in FIG. The distance d2 is larger than the distance d2 between the specific shapes adjacent in the first direction (vertical direction, Z direction) (d1> d2), and the distance d1 is in the range of 50 mm to 300 mm. Furthermore, the width S3 in the second direction (left-right direction) of the specific shape is formed in the range of 50 mm to 300 mm.
