PROBLEM TO BE SOLVED: To provide a lighting device by which a constant light quantity can be obtained by radiating a laser beam of a constant light quantity to a fluorescent body, and a constant light quantity is discharged to a constant direction, and a vehicle headlight.SOLUTION: A lighting device (10) comprises: a laser light source (11) which outputs a laser beam; a collimator lens (12) which parallelizes the laser beam; a scanning mirror (13) which reflects the parallelized laser beam, and can oscillate at a prescribed cycle; a light emitting part (14) which generates fluorescent light at a radiation position of the reflected laser beam; and a reflector (15) which is arranged while opposing a light emitting side of the light emitting part, and reflects the fluorescent light generated by the laser beam which is radiated to the light emitting part from the scanning mirror from an opening part.SELECTED DRAWING: Figure 1

    【課題】一定の光量のレーザ光を蛍光体に照射すれば、一定光量の光が得られ、一定の方向には一定量の光量が放射される照明装置及び車両用前照灯を提供する。【解決手段】照明装置(10)は、レーザ光を出力するレーザ光源(11)と、レーザ光を平行化するコリメータレンズ(12)と、平行化されたレーザ光を反射するとともに所定の周期で揺動可能な走査用ミラー(13)と、反射されたレーザ光の照射位置で蛍光を生じる発光部(14)と、前記発光部の発光側に対向して設けられ、開口部から前記走査用ミラーから前記発光部に照射されたレーザ光による前記蛍光を反射するリフレクタ(15)を備える。前記発光部は、中央部に比べて周辺部のほうが蛍光物質の密度を薄く塗布される。【選択図】図1
