< Topic >To assure the extensive conversion portable degree of freedom to array direction of each LED emitter the emitter which is stored to the box as the LED emitter, be able to correspond to the bias of the illumination simply, in addition to corresponding to the illumination specification of plant cultivation at interior extensively with the simplification of exchange of the LED emitter, the external electrode of the LED emitter and the illuminating where stabilization of registration fixing of the electrode board which is jointed to power source is assured are offered.Solutions+ Electrode terminal area 4 and - electrode terminal area 5 distribution facilities to do on left and right of radiator 2 of the plate-like which supplies on cartridge head of the box 1, each electrode terminal area 4 and 5 junction through the insulator, electrode board 3e of each outside on left and right of the respective LED emitter 3 and 3f through the cushion body and the holding down gold by each electrode board 4d and 5d which are locked with insulating bis with insulating bis and the insulating nut.< Choice figure >Drawing 1【課題】箱体に収められる発光体をLED発光体として、各LED発光体の配列方向への移動自由度の広範化を図り、照明の偏りに簡便に対応でき、LED発光体の交換の簡易化により、屋内での植物栽培の照明仕様に広範に対応できる上、LED発光体の外部電極と電源に接続される電極板との位置決め固定の安定化が図られる照明装置を提供する。【解決手段】箱体1の底部に収められる平板状の放熱体2の左右に+電極接続部4と-電極接続部5とを配設し、各電極接続部4、5は絶縁体を介して絶縁ビスで固定される各電極板4d、5dにそれぞれLED発光体3の左右の各外部電極板3e、3fが絶縁ビス、絶縁ナットにより、クッション体と押さえ金を介して接合される。【選択図】図1
