  By the way, in a rail vehicle, there is a case where vehicles having a crew room are connected in the middle of a train due to vehicle organization. In such a case, although a crew member is not stationed in a crew member room, a passenger etc. may use a passage (penetration passage) provided in the center of a crew member room. Therefore, for the purpose of ensuring the safety of passengers who pass through the throughway, lighting members are lit to illuminate the throughway brightly or to alert the passengers when there is a step in the throughway. It is necessary to keep. On the other hand, when the crew room is organized as a driver's cab or conductor's cab, to ensure safety during driving, the lighting members are turned off reliably to avoid poor visibility due to the reflection of the lighting members on the windows. There is a need to. Therefore, in a lighting device used for a vehicle having a crew room having a through-passage, safety when the through-passage of the crew room is used by passengers, etc., and the crew room is used as a cab or conductor room. From the standpoint of ensuring both safety during driving, there is a demand for a technique that can prevent erroneous operation of lighting members on and off.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a railway vehicle lighting device that can prevent erroneous operation of turning on / off a lighting member.

A railcar lighting device used in a vehicle having a stand selection switch, which is disposed in the vicinity of a through-passage and connected to a power source of the vehicle, and a power supply state from the power source to the lighting member A first switching means for switching the power supply, and the switching means turns on the power supply state from the power source to the lighting member in synchronization with the cab selection switch being in the middle position, and the cab selection switch The power supply state from the power source to the lighting member is turned off in synchronism with the position or the rear position.

  This railway vehicle lighting device includes a lighting member in the vicinity of a through-passage in a vehicle including a crew room having a through-passage. The lighting member is turned on / off by the first switching means. That is, the first switching means is used when the cab selection switch is in the middle position (when the vehicles having the crew room are connected in the middle of the train and the through-passage of the crew room is used by passengers, etc.). The lighting member is turned on synchronously, and the function of illuminating the through passage brightly for passengers and the like passing through the through passage, and alerting the passenger etc. when there is a step in the through passage is exhibited. On the other hand, the first switching means is when the cab selection switch is in the front position (when the crew room is used as a driver's cab) or when it is in the rear position (when the crew room is used as a conductor's cab). The lighting member is turned off in synchronization with () to function as an interlock for avoiding poor visibility due to the reflection of the lighting member on the window portion of the crew room. As described above, in this railway vehicle lighting device, the lighting member is reliably switched on and off in conjunction with the knitting mode of the vehicle having the crew room by the first switching means. As a result, the lighting member can be prevented from being erroneously turned on / off, the safety of passengers when the through-passage of the crew room is used by passengers, etc., and when the crew room is used as a cab or conductor room Both safety during driving can be guaranteed.

  Moreover, it is preferable that a power supply is a power supply for wipers in a vehicle. A wiper in a railway vehicle is a device that is normally operated when a crew cabin is used as a driver's cab or a conductor's cabin. Therefore, when the vehicle having the crew room is in the middle position, it is possible to use the surplus wiper power source as the power source for the lighting member. In this case, it is not necessary to separately provide a power supply for the lighting member, so that the apparatus configuration can be simplified.

  In addition, the vehicle is provided with a manual switch for manually switching the power supply state from the wiper power source to the wiper, and the power supply state from the wiper power source to the wiper is turned on by the manual switch. In synchronism with this, it is preferable to further include second switching means for turning off the power supply state from the wiper power source to the lighting member. The wiper may be operated even when the crew room is in the middle position, such as when connecting vehicles. In this case, if the wiper and the lighting member are supplied with power from the same power source, the operation of the wiper may cause the lighting member to flicker, leading to a decrease in workability. Therefore, when the crew room is in the middle position and the wiper is operated, the lighting member is automatically turned off by the second switching means, so that the workability can be prevented from being lowered.

  As described above, according to the railway vehicle lighting device according to the present invention, lighting is performed by switching the power supply state to the lighting member in conjunction with the knitting mode of the vehicle including the crew room having the through passage. Incorrect operation of lighting / extinguishing of members can be suppressed.

  Here, the circuit configuration of the railcar lighting device 13 having the above-described configuration will be described with reference to FIG.

  As shown in FIG. 5, the circuit 30 for the railway vehicle lighting device 13 includes a DC 100V vehicle power supply 31 and a wiper power supply 32 obtained by transforming the vehicle power supply 31 to DC24V. The step light 18 described above is electrically connected to the driver-side wiper 33 and the assistant-side wiper 34, respectively. In addition, a switching unit (first switching unit) 36 is provided between the wiper power supply 32 and the step light 18. The switching unit 36 is housed in the casing 11 (see FIG. 2) of the cab selection switch 10 and is selected from the three positions of the cab selection switch 10 in front, middle, and rear positions by the operation lever 12. The power supply state from the wiper power supply 32 to the step light 18 is switched in conjunction with

  That is, the switching unit 36 turns on the power supply state from the wiper power supply 32 to the step light 18 in synchronization with the cab selection switch 10 being in the middle position, and turns on the step light 18. Further, in synchronization with the cab selection switch 10 being in the front position or the rear position, the switching unit 36 turns off the power supply state from the wiper power supply 32 to the step light 18 and turns off the step light 18. .

  Further, manual switches 37 and 38 are provided between the switching unit 36 and the wipers 33 and 34, respectively. The manual switches 37 and 38 are disposed in the crew room 2A, and the crew can arbitrarily switch between operation and stop of the wipers 33 and 34 by operating the manual switches 37 and 38. . On the other hand, no manual switch is provided between the switching unit 36 and the step light 18. Therefore, the step light 18 can be turned on / off only by operating the cab selection switch 10.

  Next, a flow for operating the lighting / extinguishing of the step light 18 in the railway vehicle lighting device 13 having the above-described configuration will be described with reference to the flowchart shown in FIG.

  First, the railway vehicle 1A having the crew member room 2A is organized as one of the first vehicle, the last vehicle, and the intermediate vehicle of the train (step S01). When this vehicle organization is performed, the operator's cab selection switch 10 is operated by an operator or the like (step S02). At this time, when the railway vehicle 1A is connected in the middle of the train, the middle position of the cab selection switch 10 is selected. Further, when the railcar 1A is knitted to the leading vehicle, the cab selection switch 10 selects the front position, and when the railcar 1A is knitted to the tail vehicle, the rear position is selected. Then, the switching unit 36 switches the current supply destination of the wiper power source 32 in conjunction with the selection of the three positions of the front position, the middle position, and the rear position of the cab selection switch 10 by the operation lever 12 (step S03).

  If the cab selection switch 10 is in the middle position in step S03, the power supply state from the wiper power source 32 to the step light 18 is switched to the on state by the switching unit 36 (step S04). The light 18 is automatically turned on (step S05). On the other hand, when the cab selection switch 10 is in the front position or the rear position in step S03, the power supply state from the wiper power source 32 to the step light 18 is switched to the off state by the switching unit 36 (step S06). The step light 18 is automatically turned off (step S07).

  As described above, the railcar lighting device 13 includes the step lights 18 arranged in the step portions 14 of the through-passage 9 in the railcar 1 </ b> A including the crew member room 2 </ b> A having the through-passage 9. The step light 18 is turned on / off by the switching unit 36 that is linked to the selected position of the cab selection switch 10. That is, the switching unit 36 synchronizes with the case where the cab selection switch 10 is in the middle position (when the railway vehicle 1A is connected in the middle of the train and the through-passage 9 of the crew room 2A is used for passengers). The step light 18 is automatically turned on, and the function of alerting the passengers and the like that the through-passage 9 has the stepped portion 14 is exhibited.

  On the other hand, the switching unit 36 is used when the cab selection switch 10 is at the front position (when the crew room 2A is used as the driver's cab) or at the rear position (the crew room 2A is used as the conductor room). The step light 18 is automatically turned off in synchronization with the case) and functions as an interlock for avoiding poor visibility due to the reflection of the step light 18 on a window portion (not shown) of the crew room 2A. As described above, in this railway vehicle lighting device 13, the switching unit 36 interlocked with the selected position of the cab selection switch 10 switches on / off the step light 18 for each knitting mode of the vehicle having the crew room 2A. It can be done reliably. Thereby, erroneous operation of turning on / off the step light 18 can be suppressed, safety when the through-passage 9 of the crew room 2A is used by passengers, and when the crew room 2A is used as a driver's cab or a conductor's cabin Both driving safety can be guaranteed.

  In the railway vehicle lighting device 13, the wiper power source 32 in the railway vehicle 1 </ b> A is used as the power source of the step light 18. Such a configuration focuses on the fact that each of the wipers 33 and 34 is an apparatus that is normally used only when the crew cabin 2A is used as a driver's cab or a conductor's cabin. Then, when the railcar 1A having the crew room 2A is in the middle position, the surplus wiper power source 32 is used as the power source of the steplight 18, whereby the power source for the steplight 18 is separately supplied to the railcar 1A. Since it is not necessary to provide the device, the device configuration can be simplified.

  The present invention is not limited to the above embodiment. For example, in the circuit 40 of the railway vehicle lighting device 13, as shown in FIG. 7, a first relay unit (second switching unit) 41 and a second relay are provided between the switching unit 36 and the step light 18. A section (second switching means) 42 may be provided. The first relay unit 41 is interlocked with the switching of the manual switch 37, and the step from the wiper power supply 32 is synchronized with the power supply state from the wiper power supply 32 to the driver-side wiper 33 being turned on. The power supply state to the light 18 is turned off. Further, the second relay unit 41 is linked with the switching of the manual switch 38 and from the wiper power supply 32 in synchronization with the power supply state from the wiper power supply 32 to the assistant wiper 34 being turned on. The power supply state to the step light 18 is turned off.

  Such a configuration assumes a case in which the wipers 33 and 34 are operated even when the railway vehicle 1A having the crew room 2A is in the middle position, such as when the railway vehicle 1A is connected. In this case, in the above embodiment, since the wipers 33 and 34 and the step light 18 are both supplied with power from the wiper power source 32, if the wipers 33 and 34 and the step light 18 are used at the same time, Depending on the operating state, the step light 18 may flicker, which may lead to a decrease in workability. Therefore, when the wipers 33 and 34 are manually operated, the step light 18 is automatically turned off by the relay units 41 and 42, thereby preventing a reduction in workability.

  Moreover, in the said embodiment, although the step light 18 attached to the level | step-difference part 14 of the through-passage 9 is illustrated as a lighting member, in order to ensure brightness by attaching a lighting member to the ceiling of a rail vehicle 1A, etc. You may comprise as interior lighting. In addition, in the upper surface of the flat plate portion 21 in the mounting plate 17, a region R disposed on the stepped portion 14 side may be provided with a scab instead of the anti-slip processing. Such a cut-out can also prevent a passer-by from falling.

  Furthermore, in the above-described embodiment, a DC 24V wiper power source is used as the power source of the step light 18, but a power source of another device in the railcar 1A may be used as long as it is a low voltage power source of DC 30V or less. Thus, when using a low-voltage power supply of DC 30 V or less, it becomes possible to connect the LEDs 27 of the step light 18 having a low withstand voltage in parallel. Therefore, even if any one of the LEDs 27 is disconnected, it is possible to minimize the extinguishing part due to the disconnection.
