PROBLEM TO BE SOLVED: To provide an intermittent light irradiation device that is a simple device exhibiting a cultivation effect comparable to sunlight.SOLUTION: Light of an LED bulb of continuous light is turned to intermittent light by rotating an irradiation surface of strong light condensed by a lens to give a margin to a light reaction and thereby to increase the cycle time of the intermittent light to a rotation speed corresponding to a general-purpose motor so as to provide a simple intermittent light irradiation device exhibiting a high cultivation effect.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】簡便な装置で太陽光に匹敵する栽培効果のある間欠光照射装置を提供する。【解決手段】連続光のLED電球の光を、レンズで圧縮した強い光の照射面を回転させる方法で間欠光となし明反応に余裕を持たせ、又これにより間欠光の周期時間を汎用のモーターに見合う回転速度まで大きくすることに由って簡便で栽培効率の高い間欠光の照射装置となしたものである。【選択図】図4
