A lighting device (3) is provided with: a main body case (10) comprising an opening (9); a translucent cover (11) that covers the opening (9) in the main body case (10); and an illuminator (12) that is arranged within the main body case (10). The illuminator (12) comprises a heat-radiating fin (14), a light source (16), an optical scanning unit (17) that scans light emitted from the light source (16), and a fluorescent material (18) that emits fluorescence as a result of being irradiated with light scanned by the optical scanning unit (17). The heat-radiating fin (14) is provided to the rear surface side of a substrate (15). The light source (16), the optical scanning unit (17), and the fluorescent material (18) are provided to the front surface side of the substrate (15). |
