PROBLEM TO BE SOLVED: To reduce anxiety of a passenger during an emergency shutdown of a main power supply.SOLUTION: An illumination system is mounted on a railway vehicle which has a first power storage section 5 to supply power to a predetermined device during an emergency shutdown of a main power supply. The illumination system has: a first power receiving section 21 which receives power from the main power supply during normal feeding of the main power supply and from the first power storage section 5 during the emergency shutdown of the main power supply in an interior lamp lighting command state; a first interior lamp 22 which is lighted up by power received by the first power receiving section 21 during the normal feeding and the emergency shutdown of the main power supply; a second power receiving section 31 which receives power from the main power supply during the normal feeling of the main power supply in an interior lamp lighting command state and does not receive power from the first power storage section 5 during the emergency shutdown of the main power supply; a second power storage section 32; and a second interior lamp 33 which is lighted up by the power received by the second power receiving section 31 during the normal feeding of the main power supply and by power from the second power storage section 32 during the emergency shutdown of the main power supply.SELECTED DRAWING: Figure 1
【課題】主電源の非常遮断時の乗客の不安感を低減する。【解決手段】照明システムは、主電源の非常遮断時に所定機器に対して電力を供給する第1の蓄電部5を有する鉄道車両に搭載される。このシステムは、前記主電源の正常給電時に室内灯点灯指令状態で前記主電源からの電力を受けるとともに前記非常遮断時に第1の蓄電部5からの電力を受ける第1の受電部21と、前記正常給電時及び前記非常遮断時に第1の受電部21が受ける電力により点灯する第1の室内灯22と、前記正常給電時に室内灯点灯指令状態で前記主電源からの電力を受けるとともに前記非常遮断時に第1の蓄電部5からの電力は受けない第2の受電部31と、第2の蓄電部32と、前記正常給電時に第2の受電部31が受ける電力により点灯するとともに、前記非常遮断時に第2の蓄電部32からの電力により点灯する第2の室内灯33とを備える。【選択図】図1
