To provide a constitution for reducing color-mixture of light sources for monitors in an emergency lighting apparatus having plural light sources for monitors.SOLUTION: A power source unit 4 comprises a case 2, a cover 16, and a circuit board 17 housed in a housing case 82 constituted by the case 2 and the cover 16. Three LEDs for monitors are arranged on the circuit board 17. Three partition walls 164a, 164b, 164c are formed on the cover 16 constituting the housing case 82. Among the three partition walls 164a, 164b, 164c, one LED 164b for a monitor is arranged between the partition wall 164a and the partition wall 164b, and one LED for a monitor is arranged between the partition wall 164b and the partition wall 164c. By partitioning the LEDs for the monitors with the three partition walls 164a, 164b, 164c, the color mixture of the lights of the light sources for the monitors is reduced.SELECTED DRAWING: Figure 11 【課題】複数のモニタ用光源を有する非常用照明器具において、モニタ用光源どうしの光の混色を低減する構成を提供する。【解決手段】電源ユニット４は、ケース２と、カバー１６と、ケース２とカバー１６とで構成される収納ケース８２に収納される回路基板１７とを備えている。回路基板１７には、３つのモニタ用ＬＥＤが配置されている。収納ケース８２を構成するカバー１６には、３つの隔壁１６４ａ、１６４ｂ、１６４ｃが形成されている。３つの隔壁１６４ａ、１６４ｂ、１６４ｃのうち、隔壁１６４ａと隔壁１６４ｂとの間に一つのモニタ用ＬＥＤ１６４ｂが配置され、隔壁１６４ｂと隔壁１６４ｃの間に一つのモニタ用ＬＥＤが配置される。３つの隔壁１６４ａ、１６４ｂ、１６４によってモニタ用ＬＥＤどうしの間をしきることで、モニタ用光源どうしの光の混色を低減する。【選択図】図１１
