PROBLEM TO BE SOLVED: To reduce influences of heat generated by a lamp and an infrared ray without increasing the size of a lighting device.SOLUTION: A lighting device includes at least two human detection sensors 140c, 140d which are disposed at a body 110 located adjacent to a lamp 200. One of the human detection sensors 140c is disposed between a longitudinal center part P0 of the lamp 200 and one end part P4c of the lamp 200. The other of the human detection sensors 140d is positioned between the center part P0 of the lamp 200 and the other end part P2d of the lamp 200. |
