PROBLEM TO BE SOLVED: To provide a car illumination device for an elevator, which is able to easily ensure the illuminance of a car when power failure occurs, while restricting equipment cost.SOLUTION: A car illumination device for an elevator 100 is applied in the elevator 100, which has a liquid crystal CPI23 provided in a car 2, and comprises: a regular-use power source 31 that supplies power to the elevator 100; a power storage device 10 that stores power used during power failure of the regular-use power source 31; a power failure detection relay part 36 that detects power failure of the regular-use power source 31 and switches the supply source of power to the elevator 100, from the regular-use power source 31 to the power storage device 10; and an emergency light 25 that is lit by power supplied by the power storage device 10. The car illumination device is provided with a display control part 92 that exerts control such that when power failure of the regular-use power source 31 is detected by the power failure detection relay part 36, the illuminance of the screen of the liquid crystal CPI23 is increased higher than illuminance preset for the regular-use operation of the elevator 100.SELECTED DRAWING: Figure 4
【課題】設備コストを抑えつつ、停電の発生時に乗りかご内の照度を容易に確保することができるエレベータのかご内照明装置の提供。【解決手段】本発明は、乗りかご2内に設けられた液晶CPI23を備えたエレベータ100に適用され、エレベータ100に電力を供給する常用電源31と、常用電源31の停電中に使用される電力を蓄積する蓄電装置10と、常用電源31の停電を検出し、エレベータ100への電力の供給元を常用電源31から蓄電装置10に切替える停電検出リレー部36と、蓄電装置10から供給された電力によって点灯する停電灯25とを備えたエレベータ100のかご内照明装置において、停電検出リレー部36によって常用電源31の停電が検出されたとき、液晶CPI23の画面の照度を、予め設定されたエレベータ100の通常運転時の照度よりも上昇させる制御を行う表示制御部92を備えた。【選択図】図4
