INDIRECT LIGHTING SYSTEM AND LED LIGHTING DEVICE

To provide an indirect lighting system which allows a user to freely change a light irradiation position and/or a light irradiation area to a bed and the like.SOLUTION: In an LED lighting device 11, an LED lighting fixture includes: an LED substrate 14 including an LED light source 13; a first convex lens 16 arranged on an upper side of the substrate; a heat radiation plate 15 provided on a back surface of the substrate and having a at a corner; a support rod 17 for LED substrate guide inserted in the through-hole of the heat radiation plate 15; a frame body 18 fixed to an apex of the support rod; a second convex lens 19 arranged at the frame body; a lifting/lowering drive mechanism 20 for vertically moving the LED substrate 14 and the heat radiation plate 15 integrally along the support rod 17; and an oscillation drive mechanism for supporting the frame body 18 so as to oscillate integrally in the vertical direction together with the LED substrate 14, the heat radiation plate 15 and the support rod 17 for LED substrate guide. The LED lighting fixture is stored in a box-shaped container 22 including a light transmissible window part 32 on a surface on the second convex lens 19 side, and it is fixed to a wall body 12.SELECTED DRAWING: Figure 2 【課題】ベッドなどへの光照射位置及び／又は光照射面積を自ら自由に変更することができる間接照明システムを提供する。【解決手段】ＬＥＤ照明装置１１は、ＬＥＤ光源１３を備えたＬＥＤ基板１４、該基板の上側に配置された第一の凸レンズ１６、該基板の背面に備えられた、隅に透孔を持つ放熱板１５、放熱板１５の透孔に挿入されたＬＥＤ基板案内用支柱１７、その支柱の頂部に固定された枠体１８、枠体に配置された第二の凸レンズ１９、ＬＥＤ基板１４と放熱板１５とを支柱１７に沿って一体的に上下移動させる昇降駆動機構２０、そして枠体１８をＬＥＤ基板１４、放熱板１５及びＬＥＤ基板案内用支柱１７と共に上下方向の一体的な揺動が可能なように支持する揺動駆動機構を含むＬＥＤ照明器具を、第二の凸レンズ１９の側の表面に光透過性窓部３２を備えた箱形容器２２の内部に収容され、壁体１２に固定されている。【選択図】図２
