| description | To provide a light source device capable of enhancing light quantity which can be taken into a fly eye integrator, while enhancing utilization efficiency of the light emitted from a plurality of LEDs.SOLUTION: A light source device includes: a plurality of LEDs; collimator optical systems arranged corresponding to the plurality of LEDs; a condensing optical system for condensing emission light from the collimator optical systems; and a fly eye integrator which emission light from the condensing optical system enters. When parallel light, which is acquired by passing the condensing optical system after travelling toward the condensing optical system with a maximum take-in angle of the fly eye integrator from a virtual primary light source arranged at a back focus position of the condensing optical system being a divergence angle, serves as a virtual secondary light source, the width of the secondary light source determined according to the shape of a light emission surface of the collimator optical system substantially coincides with the width of the virtual secondary light source.SELECTED DRAWING: Figure 2
【課題】複数のＬＥＤから出射された光の利用効率を高めながらも、フライアイインテグレータ内に取り込むことのできる光量を高めることのできる光源装置を提供する。【解決手段】光源装置は、複数のＬＥＤと、前記複数のＬＥＤに対応して配置されたコリメート光学系と、コリメート光学系からの出射光を集光する集光光学系と、集光光学系からの出射光が入射されるフライアイインテグレータとを備える。集光光学系のバックフォーカス位置に配置された仮想一次光源からフライアイインテグレータの最大取込角を発散角として集光光学系に向かって進行した後に集光光学系を通過して得られる平行光を仮想二次光源としたとき、コリメート光学系の光出射面の形状に応じて決定される二次光源の幅と仮想二次光源の幅とが実質的に一致している。【選択図】図２ |
