The pair of side plate portions 42B are formed so that the base end side is connected to both side portions of the bottom plate portion 42A and the tip end side extends in a direction (forward) away from the bottom plate portion 42A. Each of the pair of side plate portions 42B has a cross section bent in a crank shape in a form in which the distance between the tip side (front side of the housing 42) is widened. The tip surface of the side plate portion 42B is formed so as to be inclined toward the base end side toward the center side (inside) in the width direction of the housing 42.

As shown in FIG. 7, the housing 42 has a holding portion 42C, an extending portion 42D, a rib portion 42E, a locking portion 42F, and an engaging portion 42G. A pair of the holding portion 42C, the extending portion 42D, the rib portion 42E, the locking portion 42F, and the engaging portion 42G are symmetrically provided at the center in the width direction of the housing 42. The pair of holding portions 42C are formed so as to project forward from the front surface of the bottom plate portion 42A. The pair of holding portions 42C are provided at predetermined intervals from the center in the width direction of the housing 42. The pair of holding portions 42C holds the light source unit 41. Specifically, the pair of holding portions 42C project to the front surface of the bottom plate portion 42A with a width slightly wider than the width of the light source unit 41. The light source unit 41 is fitted between these pair of holding portions 42C.

The pair of extending portions 42D are formed so as to be connected to both side portions of the bottom plate portion 42A and extend outward. A plurality of notches 42H formed side by side in the longitudinal direction are formed in each of the pair of extending portions 42D. When the housing 42 is attached to the frame 51, the engaging claws 51A on the frame 51 side engage with these notches 42H (see FIG. 5).

The pair of rib portions 42E are formed so as to extend outward from each outer surface of the pair of side plate portions 42B. When the lighting device 40 is fixed to the frame 51, the rib portion 42E has a rear surface that comes into contact with the open end of the frame 51 (see FIG. 5). Each rib portion 42E is provided at a position closer to the rear end than the front end portion of the housing 42. The rib portion 42E comes into contact with the front end of the frame 51 when the housing 42 is attached to the frame 51. As shown in FIG. 5, when the lighting device 40 is arranged on the wall surface C, the rib portion 42E forms the bottom surface of the joint between the lighting device 40 and the adjacent wall panels 23 and 24, and is embedded in the joint.

The pair of locking portions 42F are formed so as to extend inward from each inner side surface of the pair of side plate portions 42B. The pair of locking portions 42F are formed with a plurality of notches (not shown) at a plurality of locations in the longitudinal direction. A clip 44 for fixing the light source unit 41 to the housing 42 is fitted in this notch.

The pair of engaging portions 42G are formed so as to extend forward from a surface facing the front side of each inner side surface of the pair of side plate portions 42B having a crank-shaped cross section. When the translucent cover 43 is attached to the housing 42, the pair of engaging portions 42G engage with the engaged portion 43B of the translucent cover 43, which will be described later. The tip of the engaging portion 42G is formed so as to project outward in a claw shape. The tip of the engaging portion 42G engages with the tip of the engaged portion 43B.

The translucent cover 43 is formed by injection molding of a resin. As shown in FIGS. 5 and 8, the translucent cover 43 has a substantially uniform cross-sectional shape in the longitudinal direction, similarly to the housing 42. The translucent cover 43 is formed in a concave cross section with an opening on the rear surface side. The translucent cover 43 is attached to the housing 42 to form an internal space for accommodating the light source unit 41 together with the housing 42. The translucent cover 43 made of resin is formed shorter than the housing 42 in consideration of the difference in thermal expansion from the aluminum housing 42. Therefore, in the lighting device 40 in the normal state (normal temperature state), the upper and lower ends of the translucent cover 43 have a gap between the lower cap 45 and the upper cap 46, which will be described later. This gap also functions as a drainage for removing water generated by dew condensation or the like in the space between the translucent cover 43 and the housing 42.

The translucent cover 43 has translucency. The translucent cover 43 transmits the light from the light source unit 41. The translucent cover 43 is non-transparent. When the translucent cover 43 is attached to the housing 42, the internal space formed by the housing 42 and the translucent cover 43 is invisible from the front side of the translucent cover 43.

As shown in FIG. 8, the translucent cover 43 has a front plate portion 43A and a pair of engaged portions 43B. The front plate portion 43A is located at the front end portion of the translucent cover 43 in a state of being attached to the housing 42. The front plate portion 43A is arranged at a predetermined distance from the bottom plate portion 42A of the housing 42 in a state where the translucent cover 43 is attached to the housing 42. The front surface of the front plate portion 43A has a curved surface shape in which the center in the width direction is located slightly forward of the side edge portion. The front surface of the front plate portion 43A is the light emitting surface 40A of the lighting device 40. Both side edges of the front plate portion 43A are formed so as to correspond to the inclined surface at the tip of the side plate portion 42B of the housing 42.

The pair of engaged portions 43B are formed so that the base end side (front end side) is connected to the rear surface of the front plate portion 43A and the front end side (rear end side) projects rearward. The tip of each engaged portion 43B is formed corresponding to the claw-shaped portion of the tip of the engaging portion 42G. The tip of the engaged portion 43B is formed in a claw shape protruding inward. Each of the pair of engaged portions 43B is engaged with the pair of engaging portions 42G of the housing 42 in a state where the translucent cover 43 is attached to the housing 42 (see FIG. 5). In this state, the seal member P1 is interposed in the gap between the pair of engaged portions 43B and the side plate portions 42B of the housing 42. As a result, watertightness is ensured at the side edge portion between the translucent cover 43 and the housing 42.

As shown in FIG. 4, a lower cap 45 is provided at the lower end of the lighting device 40. The lower cap 45 is fixed to the lower end surface of the housing 42 by being screwed from below. The lower cap 45 is formed in a stepped shape in which the width and front-rear length on the upper end side are reduced as compared with the width and front-rear length on the lower end side. In the lower cap 45, the reduced upper end side portion is inserted into the space between the housing 42 and the translucent cover 43, and the lower end side portion is lowered so as to follow the outer shape of the housing 42 and the translucent cover 43. It is connected to the housing 42 in a so-called in-row shape extending in the shape of. A waterproof packing (not shown) is interposed between the lower cap 45 and the housing 42 in the connection direction (vertical direction). The lower end of the light source unit 41 is placed on the upper end of the lower cap 45. A waterproof packing P2 is interposed between the back surface (rear surface) of the translucent cover 43 and the lower cap 45.

As shown in FIG. 4, an upper cap 46 is provided at the upper end of the lighting device 40. The upper cap 46 is fixed to the upper end surface of the housing 42 by being screwed from above. The lower end of the upper cap 46 is inserted into the space formed between the housing 42 and the translucent cover 43. The upper cap 46 has a flat plate-shaped portion that abuts on the upper end surface of the housing 42, and the lower end portion is inserted into the space between the housing 42 and the translucent cover 43. A waterproof packing P2 is interposed between the upper cap 46 and the back surface (rear surface) of the translucent cover 43. The upper cap 46 forms a through hole (not shown) that communicates the internal space and the external space of the lighting device 40. This through hole is formed so as to penetrate the upper cap 46 vertically and functions as a wiring path for the light source unit 41.

At the four corners of the floor member 10, four pillar members 50 constituting the skeleton of the bathroom unit 1 are erected (see FIG. 5). A frame 51 is erected adjacent to one of the four pillar members 50. The pillar member 50 and the frame 51 are each formed by bending a plate-shaped steel material. The frame 51 fixes the lighting device 40. The frame 51 is fixed to the pillar member 50 farthest from the bathroom door 3 among the two pillar members 50 located on the wall surface B side. As shown in FIG. 5, the frame 51 according to the present embodiment is arranged adjacent to the wall surface C side of the pillar member 50.

As shown in FIG. 5, the frame 51 is formed in a substantially U-shaped cross section with an opening on the front surface. The frame 51 has an engaging claw 51A. A plurality of engaging claws 51A are provided side by side in the longitudinal direction of the bottom surface of the frame 51. The engaging claw 51A is formed so as to project forward from the bottom surface of the frame 51 and extend in the vertical direction. The engaging claw 51A is inserted into the notch 42H formed in the extending portion 42D of the housing 42 of the lighting device 40 to fix the lighting device 40. Specifically, when the housing 42 is attached to the frame 51, the extension portion 42D abuts on the bottom surface of the frame 51 together with the bottom plate portion 42A. An engaging claw 51A is inserted into each notch portion 42H from the rear surface side of the extending portion 42D. The length of each notch portion 42H in the longitudinal direction is formed longer than the vertical length of the engaging claw 51A. When the engaging claw 51A is inserted into the notch portion 42H and the entire lighting device 40 is slid downward, the engaging claw 51A engages with the extending portion 42D from below. In this way, the lighting device 40 is fixed to the frame 51 by the engagement between the notch portion 42H and the engaging claw 51A.

As described above, the light emitting surface 40A is arranged on substantially the same surface as the wall surface C. Specifically, in the case of the present embodiment, the light emitting surface 40A is located in front of the wall surface C within the range of the above-mentioned "substantially the same surface".

As described above, the lighting device 40 is formed to have a vertical length of 90% or more of the height of the bathroom space S. The lighting device 40 is formed to be shorter than the height of the bathroom space S in the length including the lower cap 45 and the upper cap 46. As a result, a slide allowance is secured when the lighting device 40 is slidly engaged with the frame 51. In the state after the lighting device 40 is fixed to the frame 51, the spacer 47 is fitted in the upper part of the lighting device 40. As a result, the lighting device 40 is held in a non-sliding state with respect to the frame 51.

As described above, the surface of the wall panel 23 forming the wall surface B is formed in a manner different from the surfaces of the wall panels 22 and 24. The surface of the wall panel 23 is formed so that light and darkness occur when it receives the illumination light from the illumination device 40. Specifically, the surface of the wall panel 23 is formed in an uneven shape. Therefore, as shown in FIG. 9, the wall surface B of the bathroom space S formed by the wall panel 23 is remarkably bright and dark due to unevenness when it receives the illumination light from the lighting device 40. Specifically, the illumination light is received on one surface side (the side where the illumination device 40 is arranged) of the convex portion, and is convex on the other surface side (the side opposite to the side where the illumination device 40 is arranged). Form the shadow of the shaped part. In this way, the wall surface B causes light and darkness due to the illumination light, and contributes to the production of the expansion of the bathroom space S and the improvement of the quality. In the case of the present embodiment, the surface of the wall panel 23 adopts a rough and irregular decoration imitating a stone.

Next, the action and effect of the bathroom unit 1 will be described. The bathroom unit 1 includes a wall panel 23 and a lighting device 40. The wall panel 23 forms the wall surface B of the bathroom space S. The lighting device 40 irradiates the illumination light from the side along the wall surface B. The wall surface B is formed so that light and darkness occur when it receives the illumination light of the illumination device 40.

When the bathroom unit 1 is irradiated with the illumination light from the illumination device 40, the wall surface B becomes bright and dark. As described above, the light and darkness on the wall surface B makes the user feel the expansion of the bathroom space S. Therefore, the bathroom unit 1 can be improved in functionality by irradiating the illumination light.

The bathroom unit 1 includes a floor member 10 and a ceiling panel 30. The floor member 10 forms the floor surface 10A of the bathroom space S, and the wall panels 21, 22, 23, 24 stand up from the peripheral edge portion. The ceiling panel 30 is arranged above the wall panels 21, 22, 23, 24 to form the ceiling surface 30A of the bathroom space S. The lighting device 40 has a light emitting surface 40A. The light emitting surface 40A extends in a vertically elongated shape between the floor surface 10A and the ceiling surface 30A of the bathroom space S.

The bathroom unit 1 emits long light in the vertical direction from a light emitting surface 40A extending vertically between the floor surface 10A and the ceiling surface 30A. As a result, in the bathroom space S, which is a limited narrow space, the user can feel the expanse of the space. In particular, the height of the bathroom unit 1 is emphasized by emitting vertically long light in the vertically long bathroom space S, and the expanse of the space can be felt.

Since the lighting device 40 irradiates a long light in the vertical direction from the wall surface C of the bathroom space S, the lighting device 40 illuminates the whole body from the side to the user of the bathroom unit 1 standing on the floor surface 10A. It can be irradiated efficiently. For example, in the case of ordinary lighting that is attached to the ceiling and irradiates the illumination light downward, if the shower head or the like of the overhead shower is arranged below the lighting, the shadow of the shower head or the like is generated. When irradiating light from the side (horizontal direction) as in the present embodiment, it is possible to illuminate the user without causing the shadow of the overhead shower. As described above, the bathroom unit 1 can efficiently irradiate the entire body of the user by irradiating the illuminating device 40 with illuminating light that is long in the vertical direction from the side.

The surface of the wall panel 23 forming the wall surface B of the bathroom space S is formed in an irregular uneven shape. When the illumination device 40 irradiates the illumination light from the side along the wall surface B, irregular brightness due to unevenness is conspicuously generated on the wall surface B that has received the illumination light. In this way, the bathroom unit 1 forms unevenness on the surface of the wall panel 23 forming the wall surface B, and irradiates the wall surface B with illumination light from the side, so that the wall surface B is bright and dark. Gradation can be made to appear effectively.

In the bathroom unit 1, the surface of the wall panel 23 forming the wall surface B is decorated with a sheet imitating a stone grain. Therefore, it is possible to produce a sharp atmosphere in the bathroom space S due to the texture of stones, and it is possible to obtain an effect due to the difference in texture between the wall surface B and the other wall surfaces E, A, and C.

The wall surface B irradiated with the illumination light emerges brighter than the other wall surfaces E, A, and C. Therefore, it is possible to obtain an effect due to the difference in brightness between the wall surface B and the other wall surfaces E, A, and C.

The bathroom unit 1 is provided with a bathroom door 3 on the wall surface E of the bathroom space S, and the lighting device 40 irradiates the wall surface B facing the wall surface E with light. In this way, the bathroom unit 1 irradiates the wall surface B facing the wall surface E provided with the bathroom door 3 with the illumination light, so that the wall surface B directly irradiated with the illumination light is the other wall surface E. It is illuminated brighter than A and C. As a result, the depth from the bathroom door 3 can be felt wide. In this way, the bathroom unit 1 can make the user who tries to enter the room through the bathroom door 3 feel the expansion of the bathroom space S even more strongly.

The bathroom unit 1 is a shower unit having a vertically long and narrow bathroom space S. In the bathroom unit 1, a lighting device 40 having a vertically long light emitting surface 40A is arranged at a corner portion BC farthest from the bathroom door 3. Therefore, the user of the bathroom unit 1 can feel the length and depth of the bathroom space S in the vertical direction even larger.

The bathroom unit 1 includes a shower device 2, and the operation unit 2A of the shower device 2 is provided on the wall surface C. The lighting device 40 is provided at a corner portion BC on the wall surface B side of the wall surface C and irradiates the wall surface B with illumination light. With such a configuration, the bathroom unit 1 can brightly illuminate the wall surface B without projecting the shadow of the operation unit 2A of the shower device 2 on the wall surface B.

The vertical length of the light emitting surface 40A of the lighting device 40 is 90% or more of the distance from the floor surface 10A to the ceiling surface 30A of the bathroom space S. As described above, since the light emitting surface 40A of the lighting device 40 is formed with a length extending substantially over the height of the bathroom space S, the user of the bathroom space S feels that the length in the vertical direction is large. It is possible to fully exert the effect of making it.

The bathroom unit 1 is configured by fitting transparent glass as a translucent member into substantially the entire inside of the door frame of the bathroom door 3. As a result, the bathroom space S can be visually recognized from the space of the adjacent washroom W. Then, when the illumination light is irradiated from the lighting device 40, the wall surface B located on the innermost side from the washroom W is brightly illuminated. As a result, the bathroom unit 1 can generate a so-called savanna effect. That is, the bathroom unit 1 can produce the bathroom space S as a space with a sense of security.

In the bathroom unit 1, the wall surface B, which is the wall surface of the facing wall of the bathroom door 3, is evenly illuminated from the lateral direction by the lighting device 40. In this way, the bathroom unit 1 can obtain the so-called wall washer effect by illuminating the wall surface B facing the bathroom door 3 from the side. That is, the user of the bathroom unit 1 can feel the bathroom space S bright and wide.

The present disclosure is not limited to the disclosure of the first embodiment described by the above description and the drawings, and includes, for example, the following embodiments.

(1) The configuration of the lighting device is not limited to that shown in the first embodiment. For example, the configuration of the light source unit, the shape and presence / absence of each member such as the housing and the translucent cover, the mounting form, and the like can be appropriately selected.

(2) The lighting device may be provided with a length that extends substantially the entire length from the floor surface to the ceiling surface of the bathroom unit. For example, the lighting device may have a configuration having a light emitting surface formed with a vertical length substantially equal to the length from the floor surface to the ceiling surface of the bathroom unit. As a result, it is possible to irradiate the illumination light from the floor surface to the ceiling surface without interruption.

(3) The arrangement of the lighting device is not limited to the arrangement shown in the first embodiment. The lighting device may be arranged on a wall surface different from that of the first embodiment, such as being arranged on a wall surface facing the wall surface provided with the bathroom door.

(4) The arrangement of the bathroom door, the opening / closing mode, and the like are not limited to the mode of the first embodiment. The bathroom door is not limited to the hinged door shown in the first embodiment, and may be, for example, a folding door, a sliding door, or the like. In the case of a hinged door, the opening is not limited to the inward opening, and may be an outward opening.

(5) The shape of the bathroom space is not limited to the shape shown in the first embodiment. For example, the bathroom space may be a substantially square in plan view, or at least a part of the wall surface may be formed in a curved surface shape. The size of the bathroom space is also not limited to the size shown in the first embodiment. The bathroom space can be, for example, about 2000 mm to 2200 mm in height. The size of the bathroom space in a plan view can be, for example, 800 mm × 800 mm, 900 mm × 1400 mm, 800 mm × 1600 mm, or the like.

(6) The form of the wall surface is not limited to the form of the first embodiment. For example, as shown in FIG. 10, the surface of the wall panel 23 may be subjected to uneven surface processing that imitates shaving marks by a chisel or an adze and decoration with a wood grain sheet. In this case, in addition to the effect of the appearance of light and darkness when receiving the illumination light, it is possible to produce a warm space by the texture of the wood and the shaving marks.

(7) The form of the wall surface is not limited to the form of the first embodiment. For example, as shown in FIG. 11, a form in which a bright portion N and a dark portion M are regularly generated in response to illumination light may be used.

(8) The wall surface may have a form in which light and darkness is generated by a combination of parts having different colors such as a white part and a black part, or absorbs light-reflecting parts such as a mirror surface and a non-mirror surface. It may be in a form that causes light and darkness depending on the combination with the part. As described above, the wall surface may have a structure in which light and darkness occur when the illumination light is received because the reflectance and the absorption rate of the illumination light are formed in a partially different form.

(9) As shown in FIG. 12, the wall surface may have a form in which a transparent surface layer B2 is formed on a base layer B1 having an uneven surface formed on one surface, so-called inner embossing. In this case, it is possible to form a smooth surface while being able to generate light and darkness due to unevenness, and it is possible to achieve both directability and cleanability.

(10) The bathroom unit is not limited to the shower unit as shown in the first embodiment. For example, as shown in FIG. 13, the bathroom unit may include a bathtub BT. In this case, the lighting device may be provided, for example, extending in the vertical direction from the upper end of the bathtub located at a height equal to or higher than the floor surface height to the ceiling surface.

(11) The wall panel is not limited to the form in which the wall panel stands up from the peripheral edge of the floor member as shown in the first embodiment. For example, when the bathroom unit includes a bathtub (see FIG. 13), the wall panel may be in the form of rising from the peripheral edge of the bathtub.
