PROBLEM TO BE SOLVED: To provide a lighting device in which the control speed in projection direction is high and which is reduced in size and weight. SOLUTION: The lighting device is equipped with: a light-emitting diode device 3; a lamp support plate 2 to which the light-emitting diode device is arranged and one end part of which is supported inclinably; micro-linear actuators 6-7 which have movable parts 5a, 6a, 7a that can make reciprocating movement in axial direction and can be supported at the stop positions and drive parts 5b, 6b, 7b to drive the movable parts and in which the movable parts are fixed to the other end part of the lamp support plate 2; and a control part which controls the reciprocating movement positions of the movable parts by giving a control electric signal to the drive parts.
