A luminaire body 10 houses the emergency illuminating device arranged next to a normal illuminating device 2. An emergency power source unit 5 is housed in the luminaire body 10 so as not to overlap with the emergency light source unit 4 as viewed from a predetermined direction. The predetermined direction is a direction orthogonal to a direction (horizontal direction) in which the normal illuminating device 2 and the emergency illuminating device are arranged, and a direction (vertical direction) in which the normal illuminating device 2 and the emergency illuminating device protrude outside the luminaire body 10.
