(First embodiment)
First, the structure of the roof structure with a lighting device according to the first embodiment will be described.

  As shown in FIGS. 1 and 2, the roof structure 1 with a lighting device is used as a roof for a carport, for example, and is composed of two light transmissive plates 10 and 11 (lower side) laminated in the vertical direction. 2), a solar panel 30 that converts solar energy into electrical energy (see FIG. 2), a light transmitting plate 10, 11, and a frame member 50 that supports the solar panel 30; The battery 70 (refer FIG. 4) which stores the electrical energy converted with the solar panel 30 and the light source 80 for illumination (refer FIG. 2) are provided.

(Light transmissive plate)
The shapes of the light transmissive plates 10 and 11 are determined according to the roof shape of the roof structure 1 with a lighting device, and are formed in, for example, a substantially rectangular shape in plan view. The peripheral portions of the light transmissive plate members 10 and 11 are supported by the frame member 50 to form a roof surface. The light transmissive plates 10 and 11 are formed in a straight line along the longitudinal direction (X-axis direction in FIG. 1) of the roof structure 1 with a lighting device, and in the short direction of the roof structure 1 with the lighting device ( In FIG. 1, it is formed in an arch shape curved along the Y-axis direction). Both the upper and lower light-transmitting plate members 10 and 11 are formed in substantially the same shape.

  Of the two sheets, the light transmissive plate 10 located on the upper side (hereinafter sometimes referred to as “upper light transmissive plate”) is composed of, for example, a light transmissive resin plate or a light transmissive glass plate. . In consideration of the amount of power generated by the solar panel 30, the upper light transmissive plate member 10 is preferably transparent. Examples of the material of the upper light transmissive plate member 10 include polycarbonate, polystyrene, acrylic resin, and the like, and it is particularly preferable to use a resin excellent in strength and weather resistance, such as polycarbonate and acrylic resin. In the present embodiment, the upper light-transmitting plate material 10 is composed of a single plate-shaped material made of the resin, but is reinforced by bonding two or more plate-shaped materials made of any resin. It may be a resin plywood. The upper light-transmitting plate material 10 may be a translucent resin plate that scatters sunlight on the surface of the resin plate by increasing the surface roughness by mat processing or the like.

  The light transmissive plate 11 located on the lower side (hereinafter sometimes referred to as “lower light transmissive plate”) is constituted by an edge-light double-sided light guide plate that emits light from both the upper and lower sides. The edge-light type double-sided light guide plate introduces light from the illumination light source 80 through its end face (edge), and this light is totally reflected inside the edge-light type double-sided light guide plate, while the flat plate of the edge-light type double-sided light guide plate As the light travels in the direction (the direction in which the plate spreads), it strikes the reflecting means 12 provided later on the surface, changes its direction, and light of a component larger than the total reflection critical angle is incident on the surface of the edge light type double-sided light guide plate. The lighting effect is obtained by using the phenomenon that appears. The lower light transmissive plate 11 (edge light double-sided light guide plate) is made of a light transmissive resin plate such as polymethyl methacrylate, polycarbonate, polystyrene, or acrylic. This light-transmitting resin plate has a low light transmittance as compared with a glass plate, but can sufficiently secure the transmittance as an edge light type double-sided light guide plate. In addition, since the light-transmitting resin plate has high strength and is lightweight, it can cope with an increase in the area of the light-transmitting plate materials 10 and 11.

In the present embodiment, the light transmissive plates 10 and 11 contain a phosphor. As the phosphor, for example, calcium phosphate 3Ca ₃ (PO ₄ ) ₂ .Ca (F, Cl) ₂ : Sb is used. When the phosphor is contained in the light-transmitting plates 10 and 11, near ultraviolet rays and visible rays are emitted. Since the fluorescent material emits fluorescent light, the illuminance of the edge light type double-sided light guide plate is increased. Further, the light transmissive plates 10 and 11 may contain a pigment instead of the phosphor. When the pigment is contained in the light-transmitting plates 10 and 11, the roof surface can be colored in a desired color, so that it can be adapted to the surrounding environment and the aesthetics can be enhanced.

As shown in FIGS. 2 and 3, at least one surface (upper surface in the present embodiment) of the lower light-transmitting plate member 11 is provided with reflecting means 12 for partially reflecting light from the illumination light source 80. It has been. In the present embodiment, the reflecting means 12 is composed of a semi-transmissive reflective dot sheet, and is attached to the upper surface of the light transmissive plate 11. The transflective reflective dot sheet has no optical absorption of titanium white (TiO ₂ ) or precipitated barium sulfate (BaSO ₄ ) as a base material on a resin sheet 12a such as polyethylene terephthalate (PET) or polycarbonate. The reflective ink 12b obtained by kneading a highly reflective pigment and a resin binder is applied by a screen printing method. The transflective reflective dot sheet reflects and refracts light (partially transmits) at a portion where the reflective ink 12b is applied, and transmits light at a portion where the reflective ink 12b is not applied. .

  The reflective ink 12b is applied according to a unique gradation pattern as shown in FIG. Specifically, the reflective ink 12 b is applied so as to be along the light emission direction of the illumination light source 80, the portion close to the illumination light source 80 is small, and increases as the distance from the illumination light source 80 increases. By the way, in this embodiment, since the light source 80 for illumination is provided in the both sides of the lower side light transmissive board | plate material 11, the reflective ink 12b is apply | coated so that an intermediate part may become large, and a lower side light transmissive board | plate material is used. 11 is configured such that the reflection amount is uniform when viewed in plan. Since the transflective reflective dot sheet is affixed to the upper surface of the lower light transmissive plate 11, an adhesive is applied to the surface opposite to the surface on which the reflective ink 12b is printed. That is, the transflective reflective dot sheet is arranged so that the surface on which the reflective ink 12b is printed is on the upper side, and an adhesive is applied to the lower surface thereof. As the adhesive, an epoxy adhesive, an acrylic adhesive, or the like is used. In addition, you may use the adhesive agent used for an adhesive tape etc.

In the present embodiment, a transflective reflective dot sheet is employed as the reflecting means 12, but the present invention is not limited to this. For example, as shown in FIG. 6A, the reflective ink 12c may be directly printed on the upper surface of the lower light-transmitting plate member 11 to form reflective dots, which may be used as reflecting means. In this case, the reflective ink 12c has a high reflectance reflectance pigment and resin binder, such as titanium white (TiO ₂ ) and precipitated barium sulfate (BaSO ₄ ), which are not optically absorbed on the upper surface of the lower light transmissive plate 11. The reflective ink 12c obtained by kneading together is applied by a screen printing method. The shape of the reflective dots is applied according to the same gradation pattern as that of the transflective reflective dot sheet.

  Moreover, you may comprise the reflection means 12 in the reflective groove | channel 13 formed in the upper surface of the lower side light-transmitting board | plate material 11, as shown in FIG.6 (b). For example, a plurality of reflection grooves 13 are formed with a V-shaped cross section, and are integrally formed by convex portions processed into a mold when the lower light-transmitting plate material 11 is injection-molded. The reflection groove 13 may be formed on the surface of the lower light transmissive plate 11 by cutting or the like. According to such a configuration, since the light incident on the reflection groove 13 is reflected downward or emitted upward depending on the incident angle, the reflecting means 12 is a semi-transmissive type.

  As shown in FIGS. 2 and 3, the reflection sheet 14 is provided on at least the end surface of the peripheral portion of the lower light transmissive plate 11 that faces the end surface on the side where the illumination light source 80 is disposed. ing. The reflection sheet 14 is a reflection means provided to return the light that escapes outward from the end face of the lower light-transmitting plate material 11 into the lower light-transmitting plate material 11. In the present embodiment, since the illumination light source 80 is provided on both sides of the lower light transmissive plate 11 (in FIG. 2, both sides in the left-right direction), the reflection sheet 14 is provided on both end surfaces in the left-right direction on the paper surface. ing. Furthermore, the reflection sheet 14 is also provided on the end surfaces at both ends in the paper front and back direction, and is provided over the entire periphery of the lower edge of the lower light transmissive plate member 11. The reflection sheet 14 is manufactured by foaming a resin having high optical transparency such as polyethylene terephthalate (PET) or polycarbonate. The diameter of the foam formed at this time is about several μm, but the higher the density of the foam, the higher the reflectance. The reflective sheet 14 is bonded to the lower light transmissive plate 11 with an adhesive having a lower refractive index than that of the lower light transmissive plate 11. The reflection sheet 14 is configured to transmit light from the outside of the lower light transmissive plate 11 toward the inside and reflect light from the inside.

  Of the end faces of the peripheral portion of the lower light transmissive plate 11, the angle of incidence of the light from the illumination light source 80 into the lower light transmissive plate 11 is set on the end surface where the illumination light source 80 is arranged. A prism sheet 17 to be adjusted is provided. The prism sheet 17 is disposed in front of the illumination light source 80 in the light irradiation direction, and is configured to widen an incident angle when the light from the illumination light source 80 enters the lower light transmissive plate 11. The prism sheet 17 has a planar rectangular shape, and is affixed to the position facing the illumination light source 80 on the end surface of the lower light-transmitting plate 11 with a resin adhesive. In the present embodiment, since a plurality of illumination light sources 80 are provided at predetermined intervals along the longitudinal direction of the frame member 50 as will be described later, the prism sheet 17 faces each illumination light source 80. A plurality of light transmission plates 11 are provided at predetermined intervals along the end surface of the lower light transmissive plate 11. In the portion where the prism sheet 17 on the end surface of the lower light transmissive plate 11 is provided, the reflection sheet 14 is cut out to form an opening. A prism sheet 17 is provided in the opening. That is, the prism sheet 17 is affixed to the end surface of the lower light-transmitting plate member 11 positioned in front of the illumination light source 80, and the reflective sheet 14 is affixed to the end surfaces of the other portions.

  A diffusion sheet 15 is provided on the lower surface of the lower light transmissive plate 11 to diffuse light from the illumination light source 80 and emit it downward. The diffusion sheet 15 is attached so as to cover the entire lower surface of the lower light transmissive plate 11. The diffusion sheet 15 is formed by unevenly mixing a resin having a high optical transparency such as polyethylene terephthalate (PET) or polycarbonate and a resin having a refractive index different from that of the resin. The diffusion sheet 15 may be a mat type sheet in which unevenness is formed on one side surface (lower surface).

(Light source for lighting)
As shown in FIGS. 2 and 3, in the present embodiment, the illumination light source 80 is configured by a light emitting diode. The light emitting diode may be of any type as long as it utilizes a light emitting element that emits visible light or ultraviolet light by recombination of electrons and holes. As the light emitting element, for example, any of red, green, and blue light emitting diodes may be used, or white light may be emitted by combining these three color light emitting diodes.

  In the present embodiment, the light emitting diode includes a light emitting element in which at least a light emitting layer is a nitride semiconductor, and an inorganic phosphor that emits fluorescence by absorbing at least a part of light emitted from the light emitting element and converting the wavelength. It is what you have. Specifically, an ultraviolet LED light emitting element that can emit light at 350 nm to 390 nm as the main peak of the emission spectrum is used. In this case, the light emitting layer is provided with a low-temperature buffer layer such as AlN on a sapphire substrate, for example, by metal organic chemical vapor deposition (MOCVD), and an AlGaN thick film, an AlGaN-based n-type nitride semiconductor, and the like. A p-type nitride semiconductor thin film is formed, and an InAlGaN light emitting layer is formed as a cladding layer. Of course, various emission wavelengths can be selected depending on the material used for the semiconductor layer and its composition.

Examples of the inorganic phosphor that emits white light include 3Ca ₃ (PO ₄ ) ₂ .Ca (F, Cl) ₂ : Sb. In addition, a mixed phosphor that emits white light and is composed of a phosphor mixture that emits blue, green, and red light. When these fluorescent materials are used, they may be formed by mixing an appropriate amount of these fluorescent materials in a light-transmitting inorganic member such as glass or a light-transmitting organic member such as resin. Further, after applying a mixture of the fluorescent material, the organic binder, and the solvent to the inner wall or the outer wall of glass or the like, it may be heated to decompose and gasify only the binder and the solvent. With such a light-emitting device, bright illumination can be obtained by efficiently converting the ultraviolet rays emitted from the light-emitting diodes into white light by the inorganic phosphor.

  A plurality of illumination light sources 80 are provided at predetermined intervals along the longitudinal direction of the frame member 50 (see FIG. 3). A specific fixing structure of the illumination light source 80 will be described later when the structure of the frame member 50 is described.

  A reflector 82 is provided around an illumination light source 80 made of a light emitting diode, and a convex lens 83 is provided at the front opening of the reflector 82.

  The reflector 82 is formed by pressing an aluminum plate or an aluminum alloy plate excellent in thermal shock resistance, and its surface (illumination surface) is polished by CMP (Chemical Mechanical Polishing). As a result, the surface roughness is reduced. The reflector 82 is formed in an umbrella shape so as to cover the light emitting diode, and reflects light irradiated backward from the light emitting diode in the front direction of the light emitting diode. The reflector 82 is not limited to aluminum or aluminum alloy. For example, a glass reflector in which a metal such as aluminum is deposited on the surface of a glass plate may be used.

  The convex lens 83 is made of glass or light transmissive resin, and converges the light reflected by the reflector 82 toward the end surface of the lower light transmissive plate 11. The convex lens 83 is fixed by being bonded or fitted to the front opening of the reflector 82.

(solar panel)
As shown in FIGS. 2 and 3, the solar panel 30 is configured by laying a light-transmissive back sheet 32 on a thin film solar cell 31. The solar panel 30 is in the form of a film and has appropriate flexibility, and is a flexible panel that can follow the surface shape of the light transmissive plates 10 and 11. As the thin-film solar battery cell 31, for example, a thin-film silicon solar photovoltaic cell having optical transparency is used. The thin-film solar battery cell 31 is formed thin and has improved light transmittance. A thin-film silicon solar cell is formed by forming a thin film of several μm made of amorphous silicon (a-Si: H), microcrystalline silicon (μc-Si: H), etc. on a flexible substrate. It is formed in a single large area. The thin film is formed by a CVD (chemical vapor deposition) method or the like. The thin-film solar battery cell 31 has a lower power generation efficiency than a conventional crystal-wafer type solar power generation cell, but has a large area to ensure a power generation amount. The thin film solar cell 31 of the present embodiment is a solar cell in which a thin film is formed on both sides of a substrate, and light can be generated by receiving light on both sides.

The beam member 51 includes a large beam 54 spanned between adjacent column members 52 and a connecting beam 55 spanned between the large beams 54 and 54 facing each other. The large beam 54 and the connecting beam 55 are formed in a hollow shape, and reinforcing ribs (not shown) are formed inside or outside as required.

The beam member 51 and the column member 52 are made of extruded shapes made of aluminum or aluminum alloy. The extruded shape made of aluminum alloy is formed based on 6063 alloy. The extruded profile based on 6063 alloy has high strength and toughness because Mg ₂ Si is finely precipitated in the matrix by heat treatment after extrusion. Furthermore, the surface of the extruded shape is subjected to an anodic oxide film treatment, which is excellent in corrosion resistance and weather resistance. In the process of anodizing film treatment, it is possible to improve the appearance as a shape material of various colors by incorporating a pigment into the surface oxide film before sealing treatment. In the present embodiment, the beam member 51 and the column member 52 are formed hollow (hollow), but may be solid (solid).

  The beam material 51 constitutes a frame of the roof surface. Here, the beam material 51 is formed by bending the large beam 54 and the connecting beam 55 extending in the Y-axis direction shown in FIG. 1 into an arc shape, and the large beam 54 and the connecting beam 55 extending in the X-axis direction. Is formed in a straight line. As a result, the roof surface has a rounded roof shape that is curved only in one direction (Y-axis direction), and accordingly, the light-transmitting plate members 10 and 11 constituting the roof surface are also in one direction ( A rounded roof shape curved only in the Y-axis direction) will be exhibited. The large beam 54 and the connecting beam 55 extending in the Y-axis direction are once formed as a straight extruded shape and then curved.

  As shown in FIGS. 2 and 3, the beam member 51 is configured to support the peripheral portions of the light transmissive plate members 10 and 11. Specifically, gripping grooves 56 are formed on the side surfaces of the large beam 54 and the connecting beam 55 on the side of the light transmissive plates 10 and 11, and the peripheral portions of the light transmissive plates 10 and 11 are formed in the gripping grooves 56.

The peripheral portions of the light transmissive plates 10 and 11 are sandwiched between upper and lower plate portions 57 and 57 that constitute upper and lower frames of the gripping grooves 56. Elastic seal members 58 and 58 are provided at the tips of the plate portions 57 and 57, respectively. The elastic seal member 58 is composed of rubber packing, and is provided between the upper surface of the upper light-transmitting plate member 10 and the tip of the upper plate portion 57 and between the lower surface and the lower portion of the lower light-transmitting plate member 11. Each is provided in a compressed state between the front end portion of the plate portion 57. As a result, it is possible to obtain an appropriate pressing force for sandwiching the light transmissive plates 10 and 11 arranged so as to sandwich the solar panel 30, and to prevent rainwater and condensed water from entering the grip groove 56. Can be prevented.

  A plurality of screw holes 61 for fixing the illumination light source 80 are formed in the bottom (back side) of the grip groove 56 at a predetermined interval. On the other hand, the illumination light source 80 includes a male screw portion 81 that is screwed into the screw hole 61 on the outer periphery of the base end portion of the light emitting diode. The illumination light source 80 is configured to be able to adjust the distance from the end surface of the lower light transmissive plate member 11 by screwing the male screw portion 81 into the screw hole 61. In other words, since the illumination light source 80 moves along the axial direction by screwing the male screw portion 81 into the screw hole 61, the axial position can be adjusted by stopping the rotation at a desired position. In addition, the illumination light source 80 can be attached by a simple operation such as screwing the male screw portion 81 into the screw hole 61, and the attachment position of the illumination light source 80 can be used as a guide.

  When the roof surface has a rounded roof shape that is curved only in one direction (Y-axis direction) as in the present embodiment, the screw hole 61 is formed in the curved frame member 50 (the large beam 54 and the connecting beam 55). The illumination light source 80 is configured to emit light along the plane direction (X-axis direction) of the lower light transmissive plate 11.

  A second grip groove 59 parallel to the grip groove 56 is formed below the grip groove 56 for fixing the light transmissive plates 10 and 11. The second grip groove 59 grips the light transmissive cover 16 provided below the light transmissive plate members 10 and 11. The light transmissive cover 16 is sandwiched between upper and lower plate portions 57, 57 that constitute the upper and lower frames of the second gripping groove 59. The upper plate portion 57 of the second holding groove 59 is also used as the lower plate portion 57 of the holding groove 56. Similar to the grip groove 56, elastic seal members 58, 58 are provided in a compressed state between the tips of the plate portions 57, 57 of the second grip groove 59 and the light-transmitting cover 16, respectively. The parts 57 and 57 are configured to hold the light-transmitting cover 16.

  The light transmissive cover 16 is provided below the lower light transmissive plate 11 so as to cover the lower light transmissive plate 11. The light transmissive cover 16 is provided for further diffusing the light emitted from the diffusion sheet 15, and is made of, for example, a light transmissive resin plate. The light transmissive cover 16 has a mat surface by forming irregularities on the surface (upper surface) on the lower light transmissive plate member 11 side. According to this, illumination can be softened.

  A hollow space 60 is also formed on the back side of the bottom of the grip groove 56 of the frame member 50. The hollow space 60 is used as a wiring space in which a power supply cord (not shown) of the illumination light source 80 is disposed. According to such a configuration, it is possible to prevent the wiring from being exposed to rainwater or the like without exposing the wiring (power supply cord) to the outside, and to obtain an aesthetic appearance.

  Next, the effect | action of the roof structure 1 with an illuminating device by the said structure is demonstrated.

  According to the roof structure 1 with the lighting device, the solar panel 30 includes the thin-film solar battery cell 31 composed of a thin-film silicon solar photovoltaic cell and the light-transmissive backsheet 32, and has two upper and lower lights. Since it is arrange | positioned between the permeable board | plate materials 10 and 11, as shown to (a) of FIG. 5 in daytime, sunlight will insert below a roof surface and a ceiling surface will become bright. Specifically, a part of sunlight passes through the roof surface in the order of the upper light-transmitting plate member 10, the solar panel 30, and the lower light-transmitting plate member 11, as shown by a thick line in FIG. 5. In the transflective reflective dot sheet constituting the reflecting means 12, a part of sunlight passes through the resin sheet 12a portion where the reflective ink 12b is not applied, and the resin sheet 12a where the reflective ink 12b is applied. Even part is transparent to some extent. And since the sunlight which injected into the lower side light-transmitting board | plate material 11 is irradiated to the fluorescent substance contained in the inside, and emits fluorescence, the illumination intensity becomes high. When the lower light-transmitting plate material 11 contains a pigment, the roof surface emits light in a desired color, and the aesthetic appearance can be enhanced.

  On the other hand, a part of sunlight is received by the upper surface of the thin-film solar cell 31 of the solar panel 30, so that power can be generated by the solar panel 30 and stored in the battery 70. Further, a part of sunlight transmitted through the solar panel 30 is reflected upward by the reflective ink 12b of the reflecting means 12 and received by the lower surface of the thin-film solar cell 31, so that the solar panel 30 generates power. The battery 70 can be charged.

  In this embodiment, since the solar panel 30 is installed and bonded and fixed to the lower surface of the upper light-transmitting plate member 10 or the upper surface of the lower light-transmitting plate member 11, the upper and lower light-transmitting plate members. 10, 11 and the solar panel can be gripped integrally, the structure is simplified, and the roof structure 1 with a lighting device can be manufactured efficiently.

  On the other hand, since the solar panel 30 includes the thin film solar cell 31 made of a thin film silicon photovoltaic cell capable of transmitting light, the thin film solar cell 31 is laid on the entire solar panel 30. And a large light receiving area can be secured. Further, since the thin film solar cell 31 is in the form of a film and is constituted by a flexible panel capable of following the surface shape of the light transmissive plates 10 and 11, as in this embodiment, it has a shape other than a flat plate shape. Since it can provide following the light transmissive board | plate materials 10 and 11, the freedom degree of a roof-shaped design can be raised.

  Moreover, since solar energy is converted into electrical energy by the solar panel 30 and stored in the battery 70, comfortable illumination can be obtained by the illumination light source 80 even at night.

  Specifically, the light from the illumination light source 80 is incident on the inside from the end face of the lower light transmissive plate member 11. Here, since the illumination light source 80 is composed of a light emitting diode, bright illumination can be obtained with a small amount of power consumption, and the illumination light source 80 can be reduced in size and the frame member 50 can be made thinner. Contributing. Thereby, a light impression can be given to the person who looks at the roof structure 1 with a lighting device. Further, since a plurality of light emitting diodes are provided in the frame member 50 with a predetermined interval, even if the frame member 50 is curved, the illumination light source 80 is specially processed. The illumination light source 80 can be formed.

  In addition, a reflector 82 is provided around the light emitting diode, and a convex lens 83 is provided at the front opening of the reflector 82, so that light from the light emitting diode is reflected forward by the reflector 82, and the convex lens 83. Is converged toward the end surface of the lower light transmissive plate 11. Therefore, the light from the light emitting diode can be efficiently used without being wasted. Further, the illumination light source 80 includes a male screw portion 81 and is screwed into a screw hole 61 formed at the bottom of the grip groove 56, so that the axial position can be adjusted. The light from the light emitting diode can be converged at the position of the prism sheet 17. The prism sheet 17 can widen the incident angle when the light from the light emitting diode is incident on the lower light transmissive plate 11, so that the light is uniformly incident inside the lower light transmissive plate 11. Therefore, the transmission of light within the lower light-transmitting plate 11 can be suitably performed.

  The light incident on the inside from the end face of the lower light transmissive plate 11 proceeds to the other end face while repeating total reflection between the upper and lower surfaces of the lower light transmissive plate 11. On the way, the incident light hits the reflection dots formed by the reflection ink 12b of the reflection dot sheet as the reflection means 12, and is irregularly reflected in the reflection dots, so that the lower surface (illumination surface) of the lower light transmissive plate member 11 is reflected. ) Or the opposite direction (upper surface). According to Snell's law, the light emitted toward the lower surface is emitted from the lower surface to the lower outside of the lower light-transmitting plate 11 when the incident angle on the lower surface is larger than the critical angle of total reflection, When the incident angle is smaller than the critical angle of total reflection, it is reflected upward on the lower surface and returns to the inside of the lower light transmissive plate member 11. At this time, since the reflective ink 12b is applied in accordance with a gradation pattern corresponding to the arrangement of the light emitting diodes, light can be reflected efficiently and illuminance can be increased. In addition, since the light incident on the lower light transmissive plate 11 is irradiated with the phosphor contained therein and emits fluorescence, the illuminance of the lower light transmissive plate 11 is increased. Furthermore, when the lower light-transmitting plate material 11 contains a pigment, the roof surface emits light in a desired color, and the appearance can be enhanced.

  On the other hand, the light emitted to the portion where there is no reflective dot on the upper surface of the lower light-transmitting plate 11 is incident on the lower light-transmitting plate 11 from the upper surface when the incident angle to the upper surface is larger than the critical angle of total reflection. Radiated upward. Here, since the thin film of the thin-film solar cell 31 is formed on both surfaces of the substrate and the solar panel 30 is a solar cell that can receive light on both surfaces and generate electric power, the lower light-transmitting plate 11 It is possible to generate electricity using the light emitted from. Depending on the peak wavelength of light emitted from the light emitting diode used as the illumination light source 80, the type of semiconductor used in the thin film solar cell 31, etc., the light is emitted from the lower light transmissive plate 11 to the outside. As a result, about 5% of the light energy can be recovered as electric energy, and light loss can be reduced.

  Moreover, since the reflection sheet 14 is provided at least on the end surface of the peripheral edge portion of the lower light transmissive plate 11 that faces the end surface on the side where the illumination light source 80 is disposed, the lower light transmissive plate 11 is provided. Light that is about to be emitted from the end face of the plate 11 can be reflected inward and returned to the inside of the lower light transmissive plate 11, and the light from the illumination light source 80 can be efficiently used without being wasted. can do. In particular, in this embodiment, since the reflection sheet 14 is provided over the entire circumference of the end surface of the lower light transmissive plate 11, light incident on the lower light transmissive plate 11 does not escape from the end surface. .

  In the present embodiment, since the diffusion sheet 15 that diffuses the light from the illumination light source 80 and emits the light downward is provided on the lower surface of the lower light transmissive plate material 11, Light emitted from the lower surface can be diffused and uniformed, and illumination with stable illuminance can be obtained. Furthermore, by diffusing the light, it is possible to reduce luminance spots that are the light reflection amount generated by the reflecting means 12 (reflective dot sheet), and to eliminate uneven illumination.

  Further, a light transmissive cover 16 that covers the lower light transmissive plate material 11 is provided below the lower light transmissive plate material 11, so that light emitted from the lower surface of the lower light transmissive plate material 11 is transmitted. Further diffusion is possible. Moreover, if the upper surface (side surface of the light guide plate) of the light transmissive cover 16 is a mat surface, the illumination can be reduced. Moreover, if a pigment is added to the light-transmissive cover 16, it can be set as colored illumination and the beauty | look and design property of the roof structure 1 with an illuminating device can also be improved.

  Moreover, in this embodiment, since the lower side light transmissive board | plate material 11 is comprised by the edge light type double-sided light guide plate, a big illumination surface can be obtained with little light. In particular, since the edge light type double-sided light guide plate radiates light from both the upper and lower surfaces, the solar panel 30 can generate power using the light emitted upward.

  The illumination light source 80 is provided on the curved frame member 50 (the large beam 54 and the connecting beam 55), and is configured to emit light in a direction orthogonal to the extending direction of the frame member 50. Even within the curved lower light-transmitting plate 11, the light from the illumination light source 80 is transmitted in the plane direction, and the reflection angle can be kept constant, so that total reflection is repeated. Can do.

  In the present embodiment, the solar panel 30 is provided on the entire roof surface, but is not limited thereto. For example, various arrangement shapes as shown in FIG. 8 may be used. (A) of FIG. 8 provides a sandwich panel P1 in which the roof surface is divided into 9 in 3 rows and 3 columns, and the solar panel 30 is sandwiched between the upper and lower light-transmitting plates 10 and 11 in the center row and column 1. At other portions (four corners), a transparent panel P2 made of a transparent resin plate is provided. According to such a configuration, the sandwich panel P1 has a cross shape in plan view, and the design is improved, and a large amount of light can be obtained from the transparent panel P2 in the daytime. In FIG. 8B, the roof surface is divided into 9 in 3 rows and 3 columns, the sandwich panel P1 is provided only in one central part, and the transparent panel P2 is provided in the other part. According to such a configuration, the amount of light collected in the daytime can be increased. In FIG. 8C, the roof surface is divided into 9 in 3 rows and 3 columns, a sandwich panel P1 is provided at a diagonal position, and a transparent panel P2 is provided in other portions. According to such a configuration, the sandwich panel P1 has an X shape in plan view, and the design is improved.

  In FIG. 8D, a belt-like sandwich panel P1 is provided on the center line of the roof surface, and a substantially rectangular transparent panel P2 is provided on both sides thereof. Illumination light sources 80 are provided at both longitudinal ends of the sandwich panel P1. According to such a configuration, the illumination can be used as an accent on the design by forming the illumination in a strip shape. Further, since a small number of illumination light sources 80 are required, energy saving and cost reduction can be achieved.

(Second embodiment)
In the second embodiment of the roof structure with a lighting device according to the present invention, as shown in FIG. 9, light is provided in the holding grooves 56 that integrally fix the upper and lower light transmissive plates 10 and 11 and the solar panel 30. A positioning stopper 65 for restricting the gripping position of the transmissive plate members 10 and 11 is formed. The positioning stoppers 65 are respectively formed on the upper and lower surfaces of the upper and lower plate portions 57 and 57 of the gripping groove 56 so as to face each other. The positioning stopper 65 may be formed as a ridge extending along the longitudinal direction of the gripping groove 56, and is formed at a plurality of locations at predetermined intervals along the longitudinal direction of the gripping groove 56. Also good. The gap between the upper and lower positioning stoppers 65 is configured to have a height at which light from the illumination light source 80 (light emitting diode) can pass. According to such a configuration, when the light-transmitting plate members 10 and 11 and the solar panel 30 are fixed to the grip groove 56, the light source 80 for illumination and the lower light can be easily fixed at an accurate position. The distance with the end surface of the permeable board 11 can be made into a desired value.

  A positioning stopper 65 having the same shape as described above is also formed in the second grip groove 59 that grips the light-transmitting cover 16. Since other configurations are the same as those in the first embodiment, the same reference numerals are given and description thereof is omitted.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, a design change is possible suitably. For example, the edge light type double-sided light guide plate constituting the light transmissive plate members 10 and 11 is not limited to the light transmissive resin plate, and may be formed of a glass plate. If the edge light type double-sided light guide plate is formed of a glass plate, a higher transmittance than that of the light-transmitting resin plate can be obtained, so that illuminance can be increased. Whether to adopt a light-transmitting resin plate or a glass plate is appropriately determined according to required illuminance, structural strength, shape, and the like.

  Further, the frame member 50 and the column member 52 of the present invention are not limited to those made of aluminum or aluminum alloy, but may be made of other materials such as steel, stainless steel, titanium, copper, or wood as long as they have the required strength.
