Description

  The present invention relates to a closing member that takes light such as sunlight into a building, and a building including the same.

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 deflection layer in which a prism is formed, 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 the amount of light taken from the outside of the building changes according to changes in the external environment such as the season and weather, the effects such as energy saving and the formation of a comfortable indoor space are sufficient. In some cases, it cannot be obtained.
For example, if the closing member provided with the daylighting member has a sufficient daylighting function in the winter, the solar altitude is generally higher in the summer than in the winter, so the light blocked by the building in the winter May increase the chances of dazzling when entering the room, and the sunshine hours will be longer than in winter, which may cause the room temperature to rise too much, preventing the formation of a comfortable indoor space. Will end up.

JP2013-15569A

  In such a case, if the daylighting member has an anti-glare function, it is possible to suppress glare in summer and temperature rise in the room. However, in winter, there may be a problem that the daylighting function of the daylighting member is too lowered due to the antiglare function. Similar problems may arise not only from seasonal changes between summer and winter, but also from weather changes such as between clear and cloudy or rainy. Alternatively, when the daylighting member is used indoors, it may be caused by a change in the light source such as between the daylight outside and the illumination light at night.

The thickness direction is the Y direction, and the left-right direction orthogonal to the thickness direction is the X direction. Of this thickness direction (Y direction), the −Y side is the outside of the building (the side on which light such as sunlight is incident), and the + Y side is the inside of the building (the side on which light such as sunlight is emitted). To do.

  As shown in FIGS. 1 (a) and 1 (b), the closing member 10 is a daylighting window installed in an opening 2 provided on the wall of the building 1, and includes a frame member 11 and a daylighting member. 20 and a light control member 40.

The frame member 11 is a member that fixes the daylighting member 20 and the light control member 40 to the opening 2 of the building 1, and is formed of a metal such as aluminum, for example. The frame member 11 fixes the first frame portion 11a that fixes the daylighting member 20, the second frame portion 11b that fixes the light control member 40, the first frame portion 11a, and the first frame portion 11a. A movable groove frame 11c that holds the second frame portion 11b so as to be movable in the left-right direction (X direction) is provided.
The first frame portion 11 a is a window frame provided so as to surround the outer peripheral edge of the daylighting member 20.
The 2nd frame part 11b is a window frame provided so that the outer periphery of the light control member 40 may be enclosed, and the shape seen from the thickness direction is formed equivalent to the above-mentioned 1st frame part 11a.

The movable groove frame 11c is a frame member in which a groove extending in the left-right direction (X direction) is formed. As shown in FIG. 2A, the groove provided in the movable groove frame 11c is formed so that the groove width on the −X side is wider on the −Y side than the groove width on the + X side. The first frame portion 11a is fixed to the −Y side of the portion where the width is increased. Moreover, the 2nd frame part 11b is hold | maintained so that the movement to the left-right direction is carried out inside the building of the groove | channel provided in the movable groove frame 11c (+ Y side).
The movable groove frame 11c of the present embodiment is provided on the vertical upper side (+ Z side) and the vertical lower side (−Z side) of the first frame portion 11a and the second frame portion 11b, and the upper end of the first frame portion 11a. While fixing an edge and a lower end edge, the upper end edge and lower end edge of the 2nd frame part 11b are hold | maintained so that a movement is possible.

Here, in this embodiment, as shown in FIG. 2A, the light control member 40 fixed to the second frame portion 11b on the movable groove frame 11c is light-fixed to the first frame portion 11a. A position facing the member 20 is defined as a facing position. Further, as shown in FIG. 2B, the position where the light control member 40 is completely removed from the position facing the daylighting member 20 fixed to the first frame portion 11a is set as the retracted position.
In addition, the above-mentioned 1st frame part 11a and 2nd frame part 11b are each formed in the opening dimension of the opening part 2 of the building 1, and the closure member 10 is the 1st frame which fixed the lighting member 20 The part 11 a is arranged in the building 1 so as to close the opening 2. Therefore, the light control member 40 is in a position that does not overlap the opening 2 in the retracted position, and overlaps the opening 2 by being moved to the facing position.

  The movable groove frame 11c has an emission surface 20b (to be described later) of the daylighting member 20 fixed to the first frame portion 11a and a first light control member 40 fixed to the second frame portion 11b at the above-described facing positions. It is desirable that the first frame portion 11a is fixed and the second frame portion 11b is movably held so that the surface 40a (described later) is in close proximity. Thereby, the thickness of the air layer interposed between the daylighting member 20 and the light control member 40 can be reduced as much as possible, and the occurrence of image deviation of transmitted light due to refraction of light caused by the air layer is suppressed. be able to.

The daylighting member 20 is a sheet-like member that takes light such as sunlight into the inside (indoor side) of the building, and as shown in FIG. 3A, in order from the outside (−Y side) of the building, The incident side panel 21, the light deflection layer 30, and the emission side panel 22 are stacked.
The daylighting member 20 is located on the outer side (−Y side) of the building in the thickness direction (Y direction), and is opposed to the incident surface 20a on which light such as sunlight is incident, and the incident surface 20a. And an emission surface 20b from which light is emitted.
The incident side panel 21 and the emission side panel 22 sandwich the light deflection layer 30 on the surface on the −Y side (outside the building) and on the surface on the + Y side (inside the building) of the light deflection layer 30. Each of the glass substrates is provided with translucency. The incident side panel 21 and the emission side panel 22 can use a resin-made substrate having translucency in addition to the above glass substrate. The daylighting member 20 of the present embodiment has a laminated glass shape when the light deflection layer 30 is sandwiched between the incident side panel 21 and the emission side panel 22.

The incident side panel 21 is disposed on the −Y side surface of the light deflection layer 30, and the −Y side surface is a surface on which light such as sunlight incident from the outside of the building is incident. In the present embodiment, the −Y side surface of the incident side panel 21 is the incident surface 20 a of the daylighting member 20.
The emission side panel 22 is disposed on the + Y side surface of the light deflection layer 30, and the + Y side surface is a surface from which light transmitted through the light deflection layer 30 is emitted toward the light control member 40 side. In the present embodiment, the + Y side surface of the emission side panel 22 becomes the emission surface 20 b of the daylighting member 20.
The incident side panel 21 and the emission side panel 22 are bonded to the light deflection layer 30 by a transparent adhesive layer (not shown). For this adhesive layer, for example, a light-transmitting thermoplastic resin or the like can be used.

  The light deflection layer 30 is a sheet-like layer having an entrance surface 30a and an exit surface 30b facing each other in the thickness direction (Y direction). Here, the incident surface 30a is a surface on the −Y side (outside of the building) of the light deflection layer 30, and is a surface on which light enters from the outside of the building. Further, the emission surface 30b is a surface on the + Y side (inside the building) of the light deflection layer 30, and is a surface from which light transmitted through the light deflection layer 30 is emitted. The normal direction of the light deflection layer 30 is parallel to the thickness direction.

The light deflection layer 30 is a member that deflects light such as sunlight incident from the incident surface 30a and emits the light from the emission surface 30b. The light deflection layer 30 is disposed between the incident side panel 21 and the emission side panel 22 so that the incident surface 30 a is along the incident side panel 21 and the emission surface 30 b is along the emission side panel 22.
As shown in FIG. 3A, the light deflection layer 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.

The base portion 31 is a member that is the basis of the light deflection layer 30 formed of a transparent material having light transmission properties. The base portion 31 extends in the left-right direction (X direction), and a plurality of grooves 31 a are arranged in the vertical direction (Z direction) along the incident surface 30 a of the light deflection layer 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 is arranged in a plurality in the vertical direction (Z direction) along the incident surface 30 a of the light deflection layer 30.

  Further, 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 layer 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 gradually becomes narrower 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 bottom surface on the incident surface 30a side.

By forming the louver part 32 in this manner, 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 the reflective surface is formed, the material of the louver part 32 and the material of the base part 31 may be the same. 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, so that the visibility through the daylighting member is improved. be able to.

FIG. 4 is a diagram showing a modified optical deflection layer, which is a cross-sectional shape in the YZ section of the optical deflection layer.
Although the light deflection layer 30 has been described as an example including the base portion 31 and the louver portion 32, the light deflection layer 30 is not limited to this, and incident light may be deflected by a different configuration.
For example, the light deflection layer 30 is formed by combining the base portion and the louver portion with the same material and sandwiching the reflection layer 34 therebetween, that is, as shown in FIG. 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 layer 30 is vertically A plurality may be arranged in the direction (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.
For example, as shown in FIG. 4B, the light deflection layer 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 light control member 40 is a sheet-like member having a first surface 40 a and a second surface 40 b facing each other, and is held movably with respect to the daylighting member 20 by the frame member 11 described above. The first surface 40 a is a surface on the −Y side of the light control member 40, is a surface that faces the emission surface 30 b of the light deflection layer 30, and is a surface on which light emitted from the emission surface 30 b is incident. The second surface 40b is a surface on the + Y side of the light control member 40, and is a surface from which light transmitted through the light control member 40 is emitted toward the inside (+ Y side) of the building.

The light control member 40 is a member that is disposed on the emission surface 20 b side of the daylighting member 20 and controls the light emitted from the daylighting member 20. Specifically, the light control member 40 causes the light emitted from the daylighting member 20 to enter the first surface 40a, reduce the light intensity, and emit the light from the second surface 40b. It is not necessary for the light control member 40 to reduce the intensity over the entire wavelength region of light, and it is sufficient if the light control member 40 can reduce the light intensity of a specific wavelength or a specific wavelength region. Whether or not the light control member 40 is reducing the light intensity is determined by taking light at an incident angle of 55 degrees from the vertical upper side (+ Z side) of the daylighting member 20 to the normal direction of the daylighting member 20 (XZ plane). The determination can be made by measuring the intensity at the emission angle of the main component of the light irradiated to the member 20 and deflected by the daylighting member 20. Here, the main component of the light deflected by the daylighting member 20 means a light emission angle at which the ratio of the light deflected by the daylighting member 20 and emitted from the daylighting member 20 is high and the luminance is the highest. The light component that is simply deflected by the daylighting member 20 without being deflected by the daylighting member 20 is excluded. Incidentally, the incident angle of 55 degrees is equivalent to the south and middle altitudes of equinox in several large cities (for example, Tokyo 54 degrees, Osaka 56 degrees, Chicago 49 degrees, Los Angeles 57 degrees, Houston 61 degrees, Beijing 51 degrees, Shanghai 59 Therefore, it is a suitable value as a judgment criterion from the viewpoint of versatility of the daylighting member.
The light control member 40 of the present embodiment has a light diffusing function of diffusing light emitted from the daylighting member 20 as a function of controlling light, and prevents glare of light emitted from the closing member 10. While realizing the glare effect, the light is uniformly emitted to the entire indoor space. Specifically, the light control member 40 has a light diffusing portion formed of a resin having light permeability containing a diffusing agent that diffuses light.

FIG. 5 is a diagram showing an intensity distribution of a certain wavelength of light emitted from the daylighting member and the light control member.
FIG. 5A is a diagram showing the light intensity distribution when the light control member 40 is provided with a light diffusion function or a light absorption function, and FIG. It is a figure which shows the intensity distribution of light at the time of providing. In each diagram of FIG. 5, the vertical axis indicates the intensity of light, and the horizontal axis indicates the light emission angle. In each drawing of FIG. 5, the emission angle θ1 of the main component of the light L1 deflected by the daylighting member 20 is the center of the horizontal axis (intersection with the vertical axis).

  Here, the light L such as sunlight that has entered from the vertically upper side (+ Z side) is deflected in the daylighting member 20 of the daylighting member 20 as shown in FIG. On the other hand, the light exits from the exit surface 20b of the daylighting member 20 in a state inclined at a predetermined exit angle θ1, and enters the first surface 40a of the light control member 40. At this time, as shown in FIG. 5A, the intensity of the light L1 emitted from the daylighting member 20 takes a maximum value at the emission angle θ1 of the main component of the light L1 deflected by the daylighting member 20, and the angle is shifted. As it goes on, the light intensity tends to decrease.

The light L1 enters the light control member 40 and is dispersed by the light diffusing agent to become light L2, and is emitted from the light control member 40. At this time, the light angle θ2 (the emission angle from the second surface) that is the main component of the light L2 is equal to the emission angle θ1 of the light L1 (θ1 = θ2), but the intensity of the light L2 is the light diffusion. Due to the dispersion of the agent, it becomes lower than the intensity of the light L1.
Thus, the intensity of the light L2 emitted from the light control member 40 is such that the light intensity at the emission angle θ1 of the main component of the light L1 deflected in the daylighting member 20 is reduced by the diffusing action of the light diffusing section. Become. By reducing the intensity of light in the visible light region (380 nm to 780 nm), a suitable antiglare effect can be obtained.
In addition, although the light control member 40 of this embodiment showed the example provided with the light-diffusion part formed from resin containing a light-diffusion agent in order to provide a light-diffusion function, it is not limited to this. For example, a fine concavo-convex shape may be formed on the second surface 40b, or a known light diffusion technique may be applied to form a light diffusion portion.

In the above description, the light control member 40 has a light diffusing function as a function of controlling light, and an example in which an antiglare effect that suppresses dazzling of light emitted from the daylighting member 20 is given. However, it is not limited to this.
For example, the light control member 40 has a light absorption function as a function of controlling light, reduces glare caused by daylighting, and optimally adjusts the amount of light into the building (indoor). Also good. In this case, the light control member 40 is provided with a light absorbing portion formed of a light-transmitting resin containing a dark pigment such as black. Even in this case, the intensity of the light L2 emitted from the light control member 40 is the main component of the light L1 deflected in the daylighting member 20, as shown in FIG. The intensity of light at the emission angle θ1 will be reduced. Instead of dark pigments, pigments other than dark colors may be incorporated into the resin to absorb light in a part of the wavelength range of visible light. As a result, the color of the light inside the structure (indoor) can be controlled to obtain an effect.

  Moreover, you may make it absorb light (for example, ultraviolet light and infrared light) of wavelength regions other than visible light by using an ultraviolet light absorber or an infrared light absorber. For example, a light absorption part that absorbs light in the near infrared light region (780 nm to 1400 nm) may be provided in the light control member 40 so as to suppress a temperature increase in the building (indoor) due to daylighting. . Even in this case, the intensity of the light in the specific wavelength region emitted from the light control member 40 is the light intensity at the emission angle θ1 of the main component of the light in the specific wavelength region out of the light L1 deflected in the daylighting member 20. Will be reduced.

  In the above description, the light control member 40 has a light deflection function different from that of the light deflection layer 30 as a function of controlling light, so that the light deflected by the daylighting member 20 It may be further deflected according to the environment or the like. In this case, the angle θ3 (the emission angle from the second surface) of the main component of the light L3 deflected by the light control member 40 is the main light L1 emitted from the daylighting member 20, as shown in FIG. This is different from the component angle θ1. Therefore, the intensity of the light L3 emitted from the light control member 40 is lower than the intensity of the light L1 emitted from the daylighting member 20 at the emission angle θ1 of the main component of the light L1 deflected by the daylighting member 20. .

FIG. 6 is a diagram illustrating a design function provided in the light control member. Each drawing in FIG. 6 is a front view of a light control member having a design function.
The light control member 40 may be provided with a design function using the above-described light diffusion function, light absorption function, and deflection function. Specifically, as shown in each drawing of FIG. 6, the light control unit 40 is provided with the light diffusing portion and the light absorbing portion in a stripe shape, a dot shape, a gradation shape, or the like, thereby providing light control. The member 40 can be provided with a design function. Moreover, you may make it provide the design function by coloring the whole surface of the light control member 40 in the same color. The width and pitch of stripes, the size and arrangement interval of dots, and the like can be appropriately set according to the size of the closing member, the installation location of the closing member, the indoor environment, and the like.
The light control member 40 may have a form having any one of the above-described light diffusion function, light absorption function, deflection function, and design function, or a form having a plurality of functions among these functions. May be.

Next, the usage example (construction example) of the closure member 10 of this embodiment is demonstrated.
As shown in FIG. 1B, the closing member 10 is attached to the opening 2 of the building 1 and is provided for taking light such as sunlight indoors.
In general, in the case of the building 1 located in the northern hemisphere, light such as sunlight is most incident on the opening 2 located on the south side. A provided closure member 10 is arranged. By moving the light control member 40 held movably in the movable groove frame 11c to a facing position facing the emission surface of the daylighting member 20, the closing member 10 has too much light taken in the daylighting member 20. The light control member 40 can prevent the room from becoming dazzling and can uniformly emit light to the entire indoor space, so that the indoor environment can be optimally adjusted.

  Even when the closing member 10 is provided in the opening 2 located on the south side, it is closed when the weather is cloudy or rainy, or when it is fine (evening from 15:00 to 16:00) in the evening. When there is a building or the like that blocks light around the member 10, sufficient light cannot be taken from the closing member 10. Therefore, in these cases, by moving the light control member 40 movably held in the movable groove frame 11c to the retracted position, the light taken in by the daylighting member 20 is emitted to the indoor side without diffusing. Thus, the interior can be brightened and the visibility to the outside of the building can be improved.

  In addition, you may change the diffusion characteristic of the light control member 40 with a light-diffusion function according to the position (direction) of the opening part 2 where the closing member 10 is arrange | positioned. For example, when the closing member 10 is disposed in the south side opening 2 as described above, the light control member 40 sets its haze value (the value of the ratio of diffused light to transmitted light) as 50% as the diffusion characteristic. be able to. On the other hand, when the closing member 10 is disposed in the opening 2 on the west side, the western sun is strongly inserted into the room in the evening, and is more dazzling than when the above-described closing member 10 is disposed in the opening 2 on the south side. Therefore, the haze value of the light control member 40 can be set to 80%, and the antiglare effect can be further enhanced.

  Further, instead of the light control member 40 having a light diffusion function, a light control member 40 having a light absorption function may be used. Here, the light absorption characteristics of the light control member 40 having a light absorption function can be appropriately changed according to the position of the opening to be arranged. For example, when the closing member 10 is disposed in the south side opening 2 as described above, the light control member 40 can set the transmittance as 80% as the light absorption characteristic. On the other hand, when the closing member 10 is disposed in the opening 2 on the west side, the western sun is strongly inserted into the room in the evening, and is more dazzling than when the above-described closing member 10 is disposed in the opening 2 on the south side. Therefore, the transmittance of the light control member 40 can be set to 60% to further enhance the antiglare effect.

In addition, when the sunlight is very strong in summer or the like, the temperature inside the room (indoors) may increase due to the light taken in by the daylighting member 20. In such a case, instead of the light control member 40 having a light diffusion function, the light control member 40 having a light absorption function for absorbing the wavelength region of infrared light may be held in the movable groove frame 11c. .
Thereby, since the wavelength region of infrared light is absorbed among the light taken in by the lighting member 20, the closing member 10 can suppress that an indoor temperature rises extremely, and cooling efficiency As a result, the indoor environment can be adjusted to an optimum state.
Further, instead of the light control member 40 having a light diffusion function, a light control member 40 having a light absorption function for absorbing a wavelength region of infrared light and a light diffusion function may be used. As a result, the closing member 10 can suppress an increase in the room temperature and also have an antiglare effect, and can adjust the indoor environment to a more optimal state.

  Moreover, the opening part 2 located in the north side of the same building 1 cannot receive external light, such as sunlight, easily, and cannot take in enough light indoors. Therefore, for the closing member 10 arranged in such an opening 2, for example, a light control member 40 having a design function colored in a warm color such as yellow or orange and formed in a gradation is used. The interior can be produced in a warm space, and the indoor environment can be adjusted more comfortably.

As described above, in the closing member 10 of the present embodiment, the light control member 40 receives the light emitted from the daylighting member 20, and the light intensity at the emission angle θ1 of the main component of the light deflected by the daylighting member 20 is increased. Reduced. The closing member 10 includes a frame member 11 that is provided on the outer periphery of the daylighting member 20 and the light control member 40 and moves the light control member 40 relative to the daylighting member 20, and the light control member 40 includes the frame member 11. Thus, the first surface 40a moves between a facing position where the first surface 40a faces the emitting surface 20b of the daylighting member 20 and a retracted position where the first surface 40a deviates from the facing position.
As a result, the closing member 10 can appropriately adjust the light taken in by the daylighting member 20 in response to a change in the external environment, etc., to be emitted indoors by the light control member 40, and realizes a good daylighting function. can do. In addition, since the light control member 40 can be easily moved from the facing position facing the daylighting member 20 to the retracted position, the indoor environment can be easily adjusted optimally according to changes in the external environment or the like.
Since the closing member 10 has a light diffusing portion in the light control member 40, when the light taken in by the daylighting member 20 is too strong and dazzling, the light is diffused to provide an antiglare effect, Light can be emitted uniformly over the entire space.

In addition, when the light control member 40 has a light absorbing portion, the closing member 10 absorbs the light when the light taken in by the daylighting member 20 is too strong and has an antiglare effect. The amount of light transmitted through the room can be adjusted appropriately.
Further, when the light absorbing portion absorbs light in a specific wavelength region, for example, when the light absorbing portion absorbs the wavelength region of infrared light, the closing member 10 is red among the light taken in by the daylighting member 20. Since the wavelength region of external light is absorbed, it is possible to suppress the indoor temperature from rising. Thereby, the closing member 10 can improve the cooling efficiency and achieve an energy saving effect, and can adjust the indoor environment to an optimum state.
