To provide a light projection device for movable body capable of widening and narrowing a light radiation range of light to be radiated even when light radiated from a light source is scanned by a mirror unit.SOLUTION: A light projection device 100 for movable body is provided on a movable body 110 and comprises: a light source that radiates light; a light scanner which comprises a mirror unit 20 for reflecting the light radiated from the light source and a drive source 21 for oscillating the mirror unit 20, and which scans light radiated from the light source; and a control unit 3 which acquires change information 30 for an angle range Ws at which the mirror unit 20 is oscillated, controls the drive source on the basis of the acquired change information to change the angle range Ws at which the mirror part 20 is oscillated, and changes a radiation range R of the light radiated from the light source.SELECTED DRAWING: Figure 9

    【課題】光源から照射された光をミラー部によって走査する場合でも、照射される光の照射範囲を広げたり狭めたりすることが可能な移動体用投光装置を提供する。【解決手段】この移動体用投光装置100は、移動体110に設けられた移動体用投光装置100であって、光を照射する光源と、光源から照射された光を反射するミラー部20と、ミラー部20を揺動させる駆動源21と、を有し、光源から照射された光を走査する光スキャナと、ミラー部20が揺動する角度範囲Wsの変更情報30を取得するとともに、取得した変更情報に基づいて駆動源を制御することによりミラー部20が揺動する角度範囲Wsを変更し、光源から照射された光の照射範囲Rを変更する制御を行う制御部3と、を備える。【選択図】図9
