PROBLEM TO BE SOLVED: To provide a lighting device in which an inspection switch for turning on a semiconductor light-emitting element when operated is prevented from blocking light radiated from light distribution control means that is provided facing the semiconductor light-emitting element when the semiconductor light-emitting element conducts emergency lighting.SOLUTION: A lighting device according to one embodiment includes: a cylindrical device body; a semiconductor light-emitting element; light distribution control means; a battery disposed in the device body; charging control means which charges the battery; informing means which displays the charging state of the battery; lighting control means which causes the semiconductor light-emitting element to light using the battery as a power source; a receiving part which receives an inspection signal; an inspection switch disposed at a position that does not block light radiated from the light distribution control means; and a substrate on which the semiconductor light-emitting element, the informing means, the receiving part, and the inspection switch are provided. The informing means, the receiving part, and the inspection switch are provided closer to the outer periphery side of the cylindrical device body than the semiconductor light-emitting element in the substrate. |
