PROBLEM TO BE SOLVED: To provide a light therapy device that can generate therapeutically effective radiation, in particular which increases health and senses of well-being of living bodies, that can be implemented at low cost and that is improved in a desired therapeutic effect.SOLUTION: The light therapy device includes a slide prepared by means of Kirlian photography for a mixture of a therapeutically effective liquid sample and ethanol, and a projection device 1 having a light means 10. The projection device 1 conducts slide projection in such a way that a liquid sample 14 contained in a light-permeable container is placed in a light path between a slide holding unit 12 and the object to be projected 18.COPYRIGHT: (C)2012,JPO&INPIT【課題】セラピー効果のある照射、特に、生体の健康・幸福感を向上させる照射を生成することができ、低コストで実施可能で、かつ、所望のセラピー効果が増大したライトセラピー装置を提供する。【解決手段】本発明のライトセラピー装置は、セラピー効果のある液体のサンプルとエタノールとの混合物をキルリアン写真で撮影・作製したスライドと、照明手段10を有する投影装置1とを備える。投影装置1は、光透過可能な容器内に収容された液体のサンプル14を光路内でスライド保持ユニット12と投影対象物体18との間に配置した状態で、スライドの投影を行う。【選択図】図1
