  One embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is referred to as a first embodiment.

[Example 1]
FIG. 1 is a schematic view of a window structure 1 according to the present invention as viewed in cross section. The window structure 1 according to the present embodiment includes a planar light emitter 2, a light emitting device 3 thereof, and glass plates 4 a and 4 b that protect the inside and the outside of the planar light emitter 2.

  The planar light-emitting body part 2 has the base material 22 by the resin-made plate body which has translucency. Although not shown, the base material 22 is formed in a rectangular shape when viewed from the right or left side of FIG. As the base material 22, acrylic resin, polycarbonate, polyvinyl chloride, or the like can be used.

  The base material 22 may be colorless and transparent or colored and transparent. A metal thin film layer 23 is laminated on the inner surface (V1 side) of the base material 22.

  The metal thin film layer 23 is a thin film layer provided with a high light reflectance such as aluminum or silver so as to have a predetermined light transmittance (light reflectance). The metal thin film layer 23 is formed on the inner surface 22a of the substrate 22 by vapor deposition or coating.

  The base material 22 and the metal thin film layer 23 constitute a so-called magic mirror M. When the magic mirror M is arranged at a location that partitions the bright space and the dark space, a person who sees the magic mirror M from the bright space can see the image of the person reflected on the magic mirror M. A person who looks at the magic mirror M from a bright space can see a bright space through the magic mirror M.

  A diffusion layer 24 is laminated on the outer surface (V2 side) of the substrate 22.

  The diffusion layer 24 is a sheet-like material having translucency, and is attached to the outer surface (V2 side) 22b of the substrate 22. In the diffusion layer 24, the reflective particles 25 are contained in a dispersed state. For the reflective particles 25, for example, silver particles are employed.

  The light-emitting device unit 3 is provided with a light-emitting unit 31 and is disposed on the base 22. Further, the bottom surface reflection portion 26 is disposed below the base material 22.

  The light emitting unit 31 includes a light emitting element 32, a housing 33, and a control circuit (not shown). The housing 33 is attached to the upper end surface of the base material 22 and houses the light emitting element 32. The light emitting element is disposed to face the upper end surface of the substrate 22.

  For the bottom reflecting portion 26, for example, a plane mirror or a convex mirror is employed. The bottom reflecting portion 26 deflects light L from the light emitting portion 31 that is incident from the upper end surface of the base material 22 and passes through the base material 22 and reaches the lower end surface of the base material 22 upward. The bottom reflector 26 is directed in a direction that allows the incident light L to reach the diffusion layer 24.

  The light L that has entered the substrate 202 from the light emitting unit 31 through the upper end surface of the substrate 22 is reflected by the metal film layer 23, the bottom reflecting unit 26, and the like within the substrate 22, and the reflective particles 25 in the diffusion layer 24. And the outer surface side (V2 side) of the diffusion layer 24 emits light.

  When the window structure 1 according to the present embodiment is used, the light emitting unit 31 is turned on when the indoor space V1 is brighter than the outdoor space V2 (for example, at night). The light L emitted from the light emitting element 32 is diffused and irradiated downward, and a part thereof directly enters the diffusion layer 24 and is diffused by the reflective particles 25.

  Part of the light is reflected by the magic mirror surface of the metal thin film layer 23, enters the diffusion layer 24, and is diffused.

  Further, a part of the light is directly reflected by the bottom reflecting portion 26 and enters the diffusion layer 24 to be diffused.

  As a result, the diffusion layer 24 on the outer surface (V2 side) of the substrate 22 emits light brightly, the entire outside glass plate 4b emits light, and the indoor side (V1 side) cannot be visually recognized from the outdoor side (V2 side). can do.

  In the present embodiment, the diffusion layer 24 is a sheet-like material having translucency, but the reflective particles 25 for diffusing light are dispersed and fixed to the outer surface side 22b of the base material 22. It may be a thing, and what formed many fine protrusion parts may be used. The protrusions may be formed by surface treatment, vapor deposition, printing, or the like of the base material 22.

  Further, it may be a spot printed with a color that easily reflects light, such as a transparent color, white color, or silver color, by silk printing.

  In the silk printing, when a large number of spots are formed, the size of the spots in the portion far from the light source is preferably larger than that in the near portion, or the interval between the spots is narrowed. Furthermore, in order to enhance the diffusion effect, the shape of the spots to be printed may be an irregular shape such as a polygonal shape or a star shape in addition to a circular shape. Furthermore, in the ink to be used, an ink in which reflective particles are mixed in a transparent color may be used.

  In this embodiment, the metal thin film layer 23 is formed on the inner surface 22a side of the base material 22 to form the magic mirror M. However, a film having a magic mirror function is attached to the inner surface 22a side of the base material 22. Things can be used.

  Thus, according to the window structure 1 of the present embodiment, during the daytime, the magic mirror function ensures the view scenery from the indoor side (V1 side) and prevents peeping from the outdoor side (V2 side). In the nighttime, the peeping prevention from the outdoor side (V2 side) is realized by the light emitting function.

  Furthermore, according to the window structure 1 of the present embodiment, unlike the conventional lighting device, there is no projection from the window frame, and the field of view through the window from the indoor side (V1 side) is further increased. spread. Moreover, there is no protrusion in the window frame, and dirt does not accumulate between the protrusion and the window. Furthermore, the situation where a protrusion part is damaged cannot also arise.

  Furthermore, the window structure 1 of the present embodiment has a bottom surface reflection portion 26. For this reason, the light L from the light emitting portion 31 is guided to the diffusion layer 24 without waste, the outer surface 22b side of the diffusion layer 24 becomes brighter, and the peep prevention from the outdoor side (V2 side) is further ensured.

The control circuit 43 controls the voltage applied to the organic EL lighting plate 42. The organic EL lighting plate 42 is allowed to transmit light when no voltage is applied, and the entire plate shines evenly when a voltage is applied.

  The inner and outer glass plates 4a and 4b of the planar light emitting body 40 protect the planar light emitting body, are transparent glass having appropriate strength and durability, and are commercially available for windows. Glass is used.

  When the window structure 1 of the present embodiment is used, when the indoor side (V1 side) is brighter than the outdoor side (V2 side) (for example, at night), a voltage is applied to the organic EL lighting plate 42 using the control circuit 43. Apply. As a result, the entire organic EL lighting plate 42 shines, the outer surface 40b of the planar light-emitting body 40 shines, the outer glass plate 4b becomes brighter, and the indoor side (V1 side) is visually recognized from the outdoor side (V2 side). It can be made impossible.

  The light-emitting device unit 3 is provided with a light-emitting unit 31 and is disposed on the base 22. Further, the bottom surface reflection portion 26 is disposed below the base material 22.

  The light emitting unit 31 includes a light emitting element 32, a housing 33, and a control circuit (not shown). The housing 33 is attached to the upper end surface of the base material 22 and houses the light emitting element 32. The light emitting element is disposed to face the upper end surface of the substrate 22.

  The diffusing portion 27 of the present embodiment is configured such that spots are arranged with white ink on the outer surface (V2 side) 22b of the base material 22, and circular spots having a diameter of 1 mm to 2 mm are arranged at intervals of 0.5 mm to 2 mm. Dispersed throughout and formed by silk printing.

  Commercially available glass plates for windows can be used for the glass plates 4a and 4b that protect the inside and outside of the planar light-emitting body portion 2.

A liquid layer, a gel layer, a solidified layer, a transparent adhesive layer, or the like may be used.

  FIG. 4 shows an arrangement state of the spots 28 by the light diffusing particles in the diffusing unit 27. (The spots are white but are shown in black in the drawing.) The diameter of the spots 28 is about 1 mm at the uppermost part and becomes larger as it goes to the lower part, and is about 2 mm at the lowermost part. As for the interval between the spots 28, the interval is wide (about 2 mm) in the upper part, and the interval is narrower (about 0.5 mm) toward the lower part.

  The light emitted from the LED light emitter 32 enters the inside through the upper end surface of the base material 22 and is directly formed on the outer surface (V2 side) 22b surface of the base material 22 as indicated by the arrow L1.
