The elevator system 13 moves up and down in a building or the like.

  As shown in FIGS. 1A (a) and 1A (b), an elevator illumination device 11A according to the first embodiment of the present invention is provided on a ceiling surface 15A of a substantially rectangular parallelepiped car 15 constituting the elevator system 13. Is provided. This ceiling surface 15A corresponds to the “construction surface relating to the elevator car” of the present invention. The car 15 includes a doorway 17 for a user to enter and exit the car 15, a door 19 for opening and closing the doorway 17, and an operation for raising and lowering the car 15 and opening / closing the doorway 17 by the door 19. An operation unit 21 is provided.

  The elevator illumination device 11 </ b> A according to the first embodiment has a function of illuminating the inside of the car 15 and enhancing the effect of illumination light in the car 15.

  In order to realize such a function, the elevator illumination device 11A according to the first embodiment includes a plurality of sets of light source units 23a to 23j, a plurality of sets of light guide paths 23a3 to 23j3 (a plurality of partition plates), as shown in FIG. 2A. Members 23a3b to 23i3b) and a rectangular dish-shaped illumination cover 12A (see FIG. 1B).

Individual light source units which are constituent elements of the plurality of sets of light source units (10 sets in the example shown in FIG. 2A) 23a to 23j have a common configuration. Therefore, the configuration of the light source unit 23c shown in FIG. 1B and FIG. 2A will be described representatively to replace the description of the plurality of sets of light source units 23a to 23j. The light source unit 23c shown to FIG. 1B and FIG. 2A is comprised by a pair of LED light source group 23c1 and 23c2 arrange | positioned so that it may mutually oppose. For example, the pair of LED light source groups 23c1 and 23c2 are disposed on both left and right ends of the car 15 as viewed from the door 19 (see FIG. 1A (a)) side. The configuration of the pair of LED light source groups 23c1 and 23c2 will be described later in detail.
In the following description, the plurality of sets of light source units 23a to 23j may be collectively referred to as “light source unit 23”.

  Individual light guides that are constituent elements of a plurality of sets of light guides (10 sets in the example shown in FIG. 2A) 23a3 to 23j3 have a common configuration. Therefore, the configuration of the light guide path 23c3 illustrated in FIG. 1B and FIG. 2A will be described as a representative to replace the description of the plurality of sets of light guide paths 23a3 to 23j3. The light guide path 23c3 shown in FIG. 1B and FIG. 2A is linear along the light irradiation direction with the axis of light from the pair of LED light source groups 23c1 and 23c2 (see, for example, the reference numeral “23c11G1” in FIG. 2D). Each has a pair of partition plate members 23b3b and 23c3b (see FIG. 1B and FIG. 2A) extending.

  The light guide path 23c3 shown in FIG. 2A is a light path having a substantially rectangular parallelepiped shape that is partitioned by a combination of a pair of LED light source groups 23c1 and 23c2 and a pair of partition plate members 23b3b and 23c3b. There is no structure such as a fluorescent lamp in the substantially rectangular parallelepiped internal space, and an air layer is formed. The light guide path 23c3 shown in FIG. 2A and the light guide path 23b3 adjacent to one side of the light guide path 23c3 are partitioned by a partition plate member 23b3b. Further, the light guide path 23c3 shown in FIG. 2A and the light guide path 23d3 adjacent to the other side of the light guide path 23c3 are partitioned by a partition plate member 23c3b.

  Similarly to the above, a partition plate member 23b3b is provided between the light source unit 23c shown in FIG. 2A (including the pair of light sources 23c1 and 23c2 and the same hereinafter) and the light source unit 23b adjacent to one side of the light source unit 23c. It is partitioned by. Further, the light source unit 23c shown in FIG. 2A and the light source unit 23d adjacent to the other side of the light source unit 23c are partitioned by a partition plate member 23c3b.

  In addition, as shown in FIG. 2A, one partition plate member 23b3b related to the light source unit 23c is one partition plate member (a pair of partition plate members related to the light source unit 23b adjacent to one side of the light source unit 23c). It also serves as the light source unit 23c side). Further, the other partition plate member 23c3b related to the light source unit 23c is one partition plate member (the light source unit 23c side) of the pair of partition plate members related to the light source unit 23d adjacent to the other side of the light source unit 23c. I also serve.

  In short, between each of the plurality of sets of light source units 23a to 23j adjacent to each other and between each of the plurality of sets of light guide paths 23a3 to 23j3 adjacent to each other, a plurality of partition plate members 23a3b to 23i3b are provided. Each pair of light guides 23a3 to 23j3 adjacent to each other is provided so as to partition.

  As shown in FIG. 2B, the pair of partition plate members 23b3b and 23c3b are provided so as to fall vertically from the top plate member 23c3c in the light guide path 23c3. The pair of partition plate members 23 b 3 b and 23 c 3 b have a function of guiding light emitted from the pair of LED light source groups 23 c 1 and 23 c 2 to the internal space of the car 15. In the first embodiment, the plurality of partition plate members including the pair of partition plate members 23b3b and 23c3b are provided in parallel to the door 19 of the car 15 (see FIG. 1A (a)).

  Each of the pair of partition plate members 23b3b, 23c3b and the top plate member 23c3c constituting the light guide path 23c3 is provided with a matte black coating. This black coating is applied to all the light guide paths 23a3 to 23j3 including the light guide path 23c3. Thereby, in the elevator illuminating device 11A according to the first embodiment, the light emitted from the pair of LED light source groups 23c1 and 23c2 acts so as to be absorbed by the pair of partition plate members 23b3b and 23c3b and the top plate member 23c3c. By doing so, the direct light from the LED light source groups 23c1 and 23c2 is mainly emitted through the illumination cover 12A, thereby enhancing the effect of illumination light in the car 15.

  The top plate member 23c3c, which is a component of the light guide path 23c3, is provided along the ceiling surface 15A of the elevator car 15. However, it does not matter whether the top plate member 23c3c and the ceiling surface 15A are in close contact with each other or at a predetermined interval. Accordingly, the top plate member 23c3c can be equated with the “construction surface relating to the elevator car” of the present invention.

  Each of the plurality of sets of light source units 23a to 23j and the plurality of sets of light guide paths 23a3 to 23j3 is covered with a rectangular dish-shaped illumination cover 12A. Here, “outward” means, for example, the light irradiation direction as seen from the light source unit 23c or the light guide 23c3. The illumination cover 12A corresponds to the “illumination cover member” of the present invention (see FIGS. 1B and 2B).

  The illumination cover 12A according to the first embodiment is configured by covering the periphery and the lower part of a rectangular cover frame member 12Ac (see FIG. 2B) with a material having optical transparency and flexibility. This illumination cover 12A supports a plurality of sets of light source units 23a-23j as shown in FIG. 2A, for example, when performing maintenance on the plurality of sets of light source units 23a-23j whose outer sides are covered by the illumination cover 12A. For this purpose, the light source frame member 18 is detachably provided.

  Specifically, as shown in FIG. 2A, a pair of hinge members 14 for supporting one side 12Aa of the lighting cover 12A is provided on one side 12Aa of the lighting cover 12A. In addition, a pair of latch members 16 for supporting the other side 12Ab of the lighting cover 12A is provided on the other side 12Ab at a position facing the one side 12Aa of the lighting cover 12A. The configuration of the hinge member 14 and the latch member 16 will be described later in detail. Then, as shown in FIG. 1B, the illumination cover 12A is opened in a state where the one side 12Aa is fixed to the light source frame member 18 via the pair of hinge members 14.

Next, a pair of LED light source groups 23c1 and 23c2 constituting the light source unit 23c will be described with reference to FIGS. 2C and 2D.
The pair of LED light source groups 23c1 and 23c2 have a common configuration. In addition, the pair of LED light source groups 23c1 and 23c2 constituting the light source unit 23c and the pair of LED light source groups constituting other plural sets of light source units have the same configuration as described above. Therefore, by representatively explaining the configuration of the LED light source group 23c1, the description will be replaced with the description of other LED light source groups including the LED light source group 23c2.

  As shown in FIG. 2C, the LED light source group 23c1 is formed by packaging red, green, and blue LED elements into one, and a required number in consideration of required brightness (example shown in FIG. 2C). In this case, only four) are used. The control board 27 (see FIG. 2D) can emit red, green, and blue colors in any combination. Thereby, arbitrary hue, saturation, and brightness can be obtained.

  In short, the LED light source group 23c1 is turned on by appropriately combining, for example, four LED light sources 23c11R, 23c11G, 23c11B, and 23c11W, and red, green, and blue LED elements included in the LED light sources 23c11R, 23c11G, 23c11B, and 23c11W, respectively. Various hues, saturations, and brightnesses can be expressed by appropriately adjusting the magnitude of the current flowing through the.

  As shown in FIG. 2D, the LED light source group 23c1 is attached and supported via a mounting bracket 25 to the top plate member 23c3c of the light guide path 23c3. As shown in FIG. 2D, the lower end portions 23b3b1 and 23c3b1 of the pair of partition plate members 23b3b and 23c3b constituting the light guide path 23c3 extend to a position where they cover the entire LED light source group 23c1 as viewed from the side. This also applies to the other partition members.

  For example, the metal mounting bracket 25 includes an attachment portion 25a attached along the top plate member 23c3c, and an inclined portion 25b extending at an angle θ (see FIG. 2D) with respect to the attachment portion 25a. The attachment portion 25a is attached to the top plate member 23c3c through a fastening member such as a screw, for example, in a state of being in close contact with the top plate member 23c3c of the light guide path 23c3. The top board member 23c3c is also provided with a control board 27 for driving the LED light source group 23c1.

On the other hand, the plate-like member 23c11 of the LED light source group 23c1 is attached to the inclined portion 25b of the attachment bracket 25. Thereby, the axis 23c11G1 of light emitted from the LED light source 23c11G described later can be set to be inclined with respect to the top plate member 23c3c so as to be directed to the internal space of the car 15. In this embodiment, the inclined portion 25b to which the LED light source group 23c1 is attached is inclined by about 44 degrees with respect to the attaching portion 25a attached along the top plate member 23c3c.
In this way, by setting the LED light source group 23c1 to be inclined, it is possible to reduce the peripheral edge of the illumination cover 12A from becoming dark.
In the first embodiment, the inclination angle θ of the LED light source group 23c1 is about 44 degrees, but the present invention is not limited to this. If the inclination angle θ of the LED light source group 23c1 is in the range of 40 degrees ≦ θ ≦ 50 degrees, the same effect can be obtained.

  Next, the light emission direction by the LED light source will be described. The four LED light sources 23c11R, 23c11G, 23c11B, and 23c11W have a common configuration, and are also common in the radiation direction of their own light. Therefore, the light emission direction related to the LED light source 23c11G will be described as a representative, and the light emission direction related to the other LED light sources 23c11R, 23c11B, and 23c11W will be replaced.

  As shown in FIG. 2D, the LED light source 23c11G has an angular expansion of 60 degrees (not particularly limited) in a circular shape with reference to the light axis 23c11G1 extending vertically from the mounting position 26 on the plate-like member 23c11 (FIG. 2D). (See reference numerals 23c11G2 and 23c11G3). The light axis 23c11G1 is basically directed to the interior space of the car 15.

In short, in the LED light source 23c11G, light directed toward the internal space of the car 15 is emitted through the illumination cover 12A with a substantially conical expansion having the mounting position 26 on the plate-like member 23c11 as a vertex.
In FIG. 2D, the range having the substantially conical shape does not include the peripheral portion of the illumination cover 12A. However, the emitted light reaches the peripheral edge of the illumination cover 12A due to light diffraction and scattering. Accordingly, the light emission range having the substantially conical shape may be appropriately set in consideration of the fact that the light reaches the peripheral edge of the illumination cover 12A.

  Next, the configuration of the hinge member 14 and the latch member 16 will be described. As shown in FIG. 3A, the hinge member 14 is configured by connecting the attachment side member 14a and the movable side member 14b via a pair of arm members 14c1 and 14c2, respectively. The attachment side member 14a of the hinge member 14 is fixed to the light source frame member 18 via a fastening member such as a screw. On the other hand, the movable side member 14b of the hinge member 14 is fixed to one side 12Aa of the illumination cover 12A via a fastening member such as a screw.

  As shown in FIG. 3B, the latch member 16 includes a pin member 16c and a receiving portion between the mounting side member 16a from which the pin member 16c projects and the movable side member 16b having the receiving portion 16d of the pin member 16c. It is configured to be detachably connected via 16d. The attachment side member 16a of the latch member 16 is fixed to the light source frame member 18 via a fastening member such as a screw. On the other hand, the movable side member 16b of the latch member 16 is fixed to one side 12Ab of the illumination cover 12A via a fastening member such as a screw.

  Next, the opening / closing operation of the illumination cover 12A will be described. The illumination cover 12A is engaged and supported by the hinge member 14 as shown in FIG. 4 by releasing the pin member 16c of the attachment side member 16a from the locked state by the receiving portion 16d of the movable side member 16b. In this state, it moves and opens in a direction parallel to the partition plate member. Thus, as shown in FIG. 1B, the plurality of sets of light source units 23a to 23j that are normally covered by the illumination cover 12A are not covered, so that, for example, maintenance related to the light source units 23a to 23j can be performed. . On the other hand, when the maintenance is completed, the lighting cover 12A is moved and closed in a direction parallel to the partition plate member by bringing the attachment side member 16a and the movable side member 16b into a locked state, and a plurality of sets of light sources The units 23a to 23j are covered with the illumination cover 12A.

The hinge member 14 and the latch member 16 are preferably attached so as to extend along a plurality of sets of light guide paths 23a3 to 23j3, for example, as shown in FIG. 2A. This is because space efficiency can be improved by optimizing the layout of the hinge member 14 and the latch member 16 in the elevator illumination device 11A.
Further, the hinge member 14 and the latch member 16 are not limited to those having the above-described configuration, and any members may be adopted as long as the illumination cover 12A can be attached and detached.

  Next, the illumination cover 12A will be described with reference to FIGS. 5A and 5B. FIG. 5A is an explanatory view of the elevator illumination device 11A according to the first embodiment with the illumination cover 12A attached, seen through from the front side. FIG. 5B is an explanatory view of the elevator illumination device 11A according to the first embodiment with the illumination cover 12A attached, seen through from the side surface side.

  As described above, the illumination cover 12A according to the first embodiment is formed of a material having flexibility in addition to light transmittance. Therefore, in the illumination cover 12A according to the first embodiment, as shown in FIGS. 5A and 5B, the central portion 12Az slightly hangs downward with respect to the peripheral ends 12Ax and 12Ay of the illumination cover 12A. . Note that the hanging shape of the illumination cover 12A according to the first embodiment shown in FIGS. 5A and 5B is actually slight, but is exaggerated for the purpose of facilitating understanding. In this case, when illumination light radiated from the plurality of sets of light source units 23a to 23j is viewed through the illumination cover 12A from the interior space of the car 15, the light guide paths adjacent to each other among the plurality of sets of light guide paths 23a3 to 23j3. Since the boundary of light between them (when different hues are adopted between light guides adjacent to each other) appears to be blurred, there is a possibility that some users may feel uncomfortable.

  Therefore, in the elevator illuminating device 11A according to the first embodiment, as shown in FIG. 5A, for example, the shape of the lower end portions 23b3b1 and 23c3b1 of the pair of partition plate members 23b3b and 23c3b constituting the light guide path 23c3 It is formed so as to draw a locus substantially equivalent to the hanging shape related to the central portion 12Az of the cover 12A.

  Further, in the elevator illuminating device 11A according to the first embodiment, as shown in FIG. 5B, the heights related to a plurality of partition plate members 23a3b to 23i3b that respectively partition a plurality of adjacent light guide paths 23a3 to 23j3. The dimensions are set so as to draw a locus that is substantially equivalent to the sagging shape of the central portion 12Az of the illumination cover 12A.
