鉄道車両には、数種類の給電系統が存在しており、給電ラインから供給される電源が電源ユニットで直流に変換されて給電される常用灯具と、バッテリからなどの電源から供給される直流が給電される非常用灯具とが設けられる。そのため、常用灯具と非常用灯具とで異なる配線を行わねばならず、天井板の上側の天井内部での配線及び艤装作業が多くなり、車両製造及びメンテナンスの作業性が悪くなる。また、常用灯具と非常用灯具とを異なる種類の灯具とすると、灯具を構成する部品の種類が増加するため、灯具を構成する部品を共通化することが求められる。 There are several types of feed systems in railway vehicles, and the power supplied from the feed line is converted to direct current by the power supply unit and supplied with a general-purpose lamp, and the direct current supplied from the power source such as a battery is supplied. And an emergency lamp. For this reason, different wiring must be performed for the ordinary lamp and the emergency lamp, and wiring and exterior work inside the ceiling above the ceiling plate are increased, and the workability of vehicle manufacture and maintenance is deteriorated. In addition, when the general-purpose lamp and the emergency lamp are different types of lamps, the types of parts constituting the lamp increase, so it is required to share the parts constituting the lamp.

そこで本発明は、鉄道車両の製造作業やメンテナンス作業を容易にしつつ、個々の室内照明装置を共通化して且つ常用と非常用との二種類の照明を設けることを目的とする。 Therefore, an object of the present invention is to make individual room lighting devices in common and provide two types of lighting, that is, for regular use and for emergency use, while facilitating the manufacturing work and the maintenance work of a railway vehicle.

前記構成によれば、複数の室内照明装置が直列接続されるので、配線及び艤装作業が少なくなり、車両製造作業やメンテナンス作業を容易にできる。しかも、室内照明群において第１電線から給電されるＬＥＤモジュールと第２電線から給電されるＬＥＤモジュールとが夫々存在するため、室内照明群を構成する各室内照明装置を共通化しながらも、常用ＬＥＤモジュールと非常用ＬＥＤモジュールとを設定することができる。 According to the above configuration, since the plurality of indoor lighting devices are connected in series, wiring and exterior work can be reduced, and vehicle manufacturing work and maintenance work can be facilitated. Moreover, since the LED module supplied with power from the first wire and the LED module supplied with power from the second wire exist in the interior lighting group, the common LED can be used while sharing the interior lighting devices constituting the interior lighting group. A module and an emergency LED module can be set.

本発明によれば、鉄道車両の製造作業やメンテナンス作業を容易にしつつ、個々の室内照明装置を共通化して且つ常用と非常用との二種類の照明を設けることができる。 According to the present invention, it is possible to make individual room lighting devices common and to provide two types of lighting, regular and emergency, while facilitating the manufacturing operation and maintenance operation of the railway vehicle.

That is, the second plus wire 33 and the second minus wire 34 are electrically connected to the second LED module 32 through the relay conductor (not shown), and the first plus wire 35 and the first minus wire 36 are electrically Not connected. That is, the first plus wire 35 and the first minus wire 36 pass in the longitudinal direction of the casing from one end to the other end of the casing 21 in the interior lighting device 12 for emergency. If the positions of the relay conductors for electrically connecting the first LED module 22 and the second LED module 32 to the electric wire are made common, the first LED module 22 and the second LED module 32 can use a common LED module.

図４は、図１に示す鉄道車両１の室内照明群５０の回路を説明する模式図である。図３及び４に示すように、第１室内照明装置１１同士を直列接続する場合、一の第１室内照明装置１１の電線２３〜２６と別の第１室内照明装置１１の電線２３〜２６とは、構造的には、互いにストレート結線される。他方、第１室内照明装置１１と第２室内照明装置１２とを直列接続する場合、構造的には以下のようにクロス結線が用いられる。 FIG. 4 is a schematic view for explaining the circuit of the interior lighting group 50 of the railcar 1 shown in FIG. As shown in FIGS. 3 and 4, when the first indoor lighting devices 11 are connected in series, the wires 23 to 26 of one first indoor lighting device 11 and the wires 23 to 26 of another first indoor lighting device 11 Structurally, they are directly connected to each other. On the other hand, when connecting the 1st room lighting installation 11 and the 2nd room lighting installation 12 in series, cross connection is used as follows structurally.
