PROBLEM TO BE SOLVED: To provide a lighting fixture in which heat radiation at the time of light emission of an LED is performed effectively, and which reduces a thermal influence by separating from a heat generation element a storage battery for lighting the LED in emergency.SOLUTION: In a lighting fixture 1, a light source is disposed inside a front half part of a substantially boat-shaped hollow body 11 having an opening on a light projecting surface, and a storage battery for performing emergency lighting of the light source is provided inside of a rear half part. While an LED array 16 which becomes a usual light source and an LED array 17 which becomes an emergency light source are juxtaposed on a surface of a heat radiation plate 15 fixed so as to cover the front half part of the opening, an electric circuit element necessary for lighting the usual light source and the emergency light source is provided inside a space of a front chamber FR formed by being partitioned by a rear surface of the heat radiation plate 15 and/or the heat radiation plate 15, and also, a shielding plate 24 for covering the rear half part of the opening is provided in an openable/closable manner. The storage battery which becomes a power source for the emergency light source is accommodated inside a space in a rear chamber BR formed by being partitioned by the shielding plate 24. |
