  Recently, there is a demand for an illuminating device 30 including the LED panel 31 as shown in FIG. Although there is no problem when the lighting device 30 having the LED panel 31 as shown in FIG. 5 is installed in the elevator car of the new elevator, the existing elevator having the fluorescent lamp 21 as shown in FIG. There is a problem when the lighting device 20 provided in the car is renewed to the lighting device 30 having the LED panel 31 as shown in FIG.

  That is, in order to change the illuminating device 20 shown in FIG. 4 to the illuminating device 30 shown in FIG. 5, for example, the ceiling 3 is replaced with a new ceiling 3, and the mounting hole 32 through which the holding member 33 shown in FIG. Form. From this state, the holding member 33 that holds the LED panel 31 and the holding member 33 that holds the power supply device 34 are inserted into the attachment holes 32 and attached to the ceiling 3.

  By the way, when such work is performed, in a state where the use of the elevator is stopped, the car is partially disassembled, the existing ceiling 3 removed from the opening on the landing side is taken out, and then the new ceiling 3 is installed. It is necessary to suspend and move it to the upper part of the car and assemble and adjust the car again. For this reason, parts cost becomes high, and much work time is required, and the serviceability with respect to the elevator user accompanying a stop of an elevator falls remarkably.

  In addition, in the illuminating device 20 as shown in FIG. 4, when the fluorescent lamp 21, the spring metal fitting 8, and the ballast 15 can be easily removed, the existing ceiling 3 may be used without removing it. However, even in such a case, the complicated work of forming a large number of mounting holes for mounting the LED panel 31 as shown in FIG. Therefore, even when the existing ceiling 3 can be diverted in this way, a great amount of work time is required for renewal, and there arises a problem that the serviceability for the elevator user accompanying the stoppage of the elevator is remarkably lowered.

In the elevator car lighting device, an LED panel provided with a plurality of LEDs and a power supply device connected to the C-shaped portion of the spring metal fitting and connected to the wiring material are mounted, and the LED panel below. And a pressing member that is fitted to the C-shaped part of the spring metal fitting and presses the mounting member against the inner surface of the C-shaped part.

  The present invention configured as described above is installed on the ceiling when renewing an illuminating device having a fluorescent lamp provided in an existing elevator car to an illuminating device having an LED panel provided with a plurality of LEDs. Remove the diffuser plate from the plate frame, remove the fluorescent lamp fitted in the C-shaped part of the spring bracket, cut the middle of the wiring material connected to the ballast provided on the ceiling of the car, Temporarily hold the wiring material portion excluding the wiring material portion connected to the ballast.

  Here, the mounting member on which the power supply device is mounted is engaged with the C-shaped portion of the spring metal fitting, and the pressing member is fitted into the C-shaped portion of the spring metal fitting in this state. Thereby, the attachment member is fixed so as to be sandwiched between the pressing member and the C-shaped portion of the spring metal fitting. Here, the LED panel provided with a plurality of LEDs is mounted below the mounting member.

  For example, in this state, the LED panel and the power supply device are connected with a wiring material. Further, the wiring member connected to the power supply device mounted on the mounting member is connected to the wiring member connected to the ballast described above and cut and temporarily held. In this way, the renewal is completed.

  As described above, according to the present invention, an LED panel provided with a plurality of LEDs can be installed without requiring replacement of the ceiling or processing of the ceiling. It is possible to reduce the work time required for the renewal to be changed to the one equipped with.

  Moreover, the present invention is characterized in that, in the above invention, the mounting member is disposed below the pressing member, and the LED panel is formed in a larger shape than the mounting member. Since the present invention configured as described above can provide an LED panel having a relatively large shape and size, the number of LED panels to be installed is reduced when securing a desired illuminance required for illumination in the car. be able to. Therefore, the present invention can further reduce the work time required for renewal.

  Further, the present invention is characterized in that in the above invention, the mounting member is disposed above the pressing member, and the LED panel is formed in a shape that is smaller than the mounting member and does not interfere with the spring metal fitting. The present invention configured as described above can ensure a large distance between the LED panel and the diffusion plate. Thereby, it can suppress that the light nonuniformity arises in a diffuser plate.

  According to the present invention, in the above invention, the pressing member comprises an annular member having a shape substantially equivalent to an annular fluorescent lamp that can be fitted to the C-shaped portion of the spring metal fitting. According to the present invention configured as described above, the mounting member engaged with the C-shaped portion of the spring metal fitting can be firmly held by the pressing member, and a stable LED panel installation structure can be realized.

  The present invention includes an LED panel provided with a plurality of LEDs and a C-shaped portion of a spring metal fitting to which a fluorescent lamp can be fitted, and a power supply device to which a wiring material is connected is mounted. An attachment member to be attached and a pressing member that is fitted to the C-shaped part of the spring metal fitting and presses the attachment member against the inner surface of the C-shaped part are provided. Along with this configuration, the present invention requires replacement of the ceiling when renewing the lighting device having the fluorescent lamp provided in the elevator car of the existing elevator to the lighting device having the LED panel provided with a plurality of LEDs. In addition, the LED panel can be installed without requiring processing of the ceiling, and the work time required for renewal can be reduced. Thereby, the fall of the service property accompanying the renewal of the in-car lighting device with respect to the user of an elevator can be suppressed less than a prior art.
