PROBLEM TO BE SOLVED: To provide an LED illumination device capable of emitting light to two directions with a simple structure.SOLUTION: An LED illumination device 1 mainly includes a frame body 3 and an LED light source 19 and the like. The frame body 3 is formed in a substantially rectangular parallelepiped shape including a bottom face, a top face 5, four side faces 9a, 9b, 9c, and 9d surrounding the outer periphery between the bottom face and the top face 5. The frame body 3 is formed by a reflection plate made of a micro foaming resin. The top face 5 is formed by a top face shielding part 13 and a plurality of top face opening parts 11 for light extraction that are mutually separate. A light source is arranged on one side face 9a formed right-angled to the bottom face. The other side face 9b facing the side face 9a arranged with the LED light source and formed right-angled to the bottom face is formed with a plurality of side face opening parts 15. The side face 9b is formed by the side face opening part 15 and a side face shielding part 17. The frame body 3 is entirely shielded by the reflection plate except for the top face 5 and the top face opening part 11 formed on the side face 9b and the side face opening part 15.SELECTED DRAWING: Figure 2 【課題】簡易な構造で二方向に光を照射することが可能なＬＥＤ照明装置を提供する。【解決手段】ＬＥＤ照明装置１は、主に、枠体３、ＬＥＤ光源１９等からなる。枠体３は、底面、天面５、底面と天面５との外周を囲む４方の側面９ａ、９ｂ、９ｃ、９ｄよりなる略直方体形状である。枠体３は、マイクロ発泡樹脂製の反射板で形成される。天面５は、天面遮蔽部１３と、相互に離間した光取出し用の複数の天面開口部１１とで形成される。底面に対して直角に形成された一方の側面９ａには、ＬＥＤ光源が配置される。ＬＥＤ光源が配置される側面９ａと対向し、底面に対して直角に形成される他方の側面９ｂには、複数の側面開口部１５が形成される。側面９ｂは、側面開口部１５と、側面遮蔽部１７とで形成される。枠体３は、天面５と側面９ｂに形成された天面開口部１１および側面開口部１５以外が全て反射板で遮蔽される。【選択図】図２
