A system for illuminating at least a portion of an object within an enclosed space includes an object configured to be moved within the enclosed space, and a beacon coupled to the object. The beacon is configured to emit a light tracking signal. A light sensor is configured to detect the light tracking signal emitted from the beacon. A lighting control unit in communication with the light sensor is configured to determine a position of the object within the enclosed space based on the light tracking signal as detected by the light sensor. A lighting assembly is in communication with the lighting control unit. The lighting control unit is configured to operate the lighting assembly to emit the illuminating light onto the at least a portion of the object based on the light tracking signal as detected by the light sensor. The system may also be configured to guide a passenger to a seat, and provide way-finding illumination.

A lighting device includes an indoor lamp (11), being provided in the cabin of a railroad vehicle (1) in order to wholly irradiate the inside of the cabin over the longitudinal direction of the vehicle, a vehicle body power supply (20), supplying electric power to the indoor lamp (11), and a storage battery (30), being charged with a voltage applied by the vehicle body power supply (20). The indoor lamp (11) includes a general lamp light source (12) and a standby lamp light source (13), being lighted at an illuminance lower than that at which the general lamp light source (12) is lighted, and the general lamp source (12) being supplied with electric power from the vehicle body power supply (20) not through the storage battery (30), while the standby lamp light source (13) being supplied with electric power from the vehicle body power supply (20) through the storage battery (30). In an emergency, electric power is supplied from the storage battery (30) only to the standby lamp light source (13), and the standby lamp light source (13) is continued to be lighted at the low illuminance.
