Kind Code:

Abstract:
Provided is an illumination device with which it is possible to easily ensure, through a simple configuration, required brightness for a vehicle as a whole during emergency, and to increase safety during evacuation without causing cost increases. The illumination device is provided with: an indoor lamp (11) which is arranged in a state to irradiate the interior of a cabin of a railroad vehicle (1) throughout in a longitudinal direction of the vehicle; a vehicle body power supply (20) which supplies electric power to the indoor lamp (11); and a battery (30) which is charged with an electric current from the vehicle body power supply (20). The indoor lamp (11) includes a general lamp light source (12) and an auxiliary lamp light source (13) that lights with a lower illuminance. The general lamp light source (12) is supplied with electric power from the vehicle body power supply (20) without passing through the battery (30). On the other hand, the auxiliary lamp light source (13) is supplied with electric power from the vehicle body power supply (20) via the battery (30). During emergency, electric power is supplied from the battery (30) only to the auxiliary lamp light source (13), wherein the auxiliary lamp light source (13) keeps lighting with the lower illuminance.
