Disclosed is irradiated with therapeutic benefits , in particular , can generate a radiation to improve the health and well-being of a living body , it can be implemented at low cost , and to provide a light therapy device desired therapy effect was increased . A light therapy device comprises a slide of a mixture of the sample and the ethanol liquid was taken , produced in Kirlian photographs of therapy effect , a projection device 1 having an illumination means 10 . Projection apparatus 1 is in a state of being placed between the slide holding unit 12 samples 14 of the liquid contained in the light- permeable container in the light path within 16 and a projection object 18 performs the projection of the slide . [ Selection Figure ] Figure 1【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】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16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
