LIGHT SOURCE DEVICE AND LIGHT PROJECTOR

To provide a light source device capable of effectively increasing light emitting intensity of the entire scanning region, and a light projector using the same.SOLUTION: A light source device 2 includes: laser light sources 11a-11c; a wavelength conversion member 18 for converting the wavelength of laser light, emitted from the laser light sources 11a-11c into other wavelength, for dispersing the wavelength-converted light; a light deflector 16 for allowing the laser light emitted from the laser light sources 11a-11c to scan on an incident surface of the wavelength conversion member 18; and a cylindrical lens 14 and a cylindrical mirror 17 for converging the laser light emitted from the laser light sources 11a-11c in a beam shape which is long in the direction crossing the scanning direction of the laser light on the incident surface 18a of the wavelength conversion member 18. The laser light sources 11a-11d and an optical system are adjusted so that the laser light emitted from the laser light sources 11a-11c is substantially overlapped with each other as a whole on the incident surface of the wavelength conversion member 18.SELECTED DRAWING: Figure 1 【課題】走査領域全体の発光強度を効果的に高めることが可能な光源装置およびそれを用いた投光装置を提供する。【解決手段】光源装置２は、レーザ光源１１ａ〜１１ｃと、レーザ光源１１ａ〜１１ｃから出射されたレーザ光の波長を他の波長に変換するとともに波長変換された光を拡散させる波長変換部材１８と、レーザ光源１１ａ〜１１ｃから出射されたレーザ光を波長変換部材１８の入射面上において走査させる光偏向器１６と、レーザ光源１１ａ〜１１ｃから出射されたレーザ光を、波長変換部材１８の入射面１８ａ上において、レーザ光の走査方向に交差する方向に長いビーム形状に収束させるシリンドリカルレンズ１４およびシリンドリカルミラー１７と、を備える。レーザ光源１１ａ〜１１ｃから出射されたレーザ光が波長変換部材１８の入射面上において全体的に略重なるように、レーザ光源１１ａ〜１１ｄと光学系が調整されている。【選択図】図１
