Since it is possible to perform accurate and reliable attachment to R, if it is attached to this type of cultivation shelf R, optimum performance can be obtained from the viewpoint of ensuring the effectiveness of the plant cultivation irradiation device 1. . For example, when an irradiation device using a fluorescent tube is attached to the cultivation shelf R, and the irradiation device using this fluorescent tube is changed (replaced) to the irradiation device 1 for plant cultivation according to the present embodiment, one shelf If one fluorescent tube is attached to the portion Rs, the plant cultivation irradiation device 1 according to the present embodiment can be attached as it is in the vacant attachment space after the fluorescent tube is removed.

  On the other hand, when attaching the plant cultivation irradiation apparatus 1 to the frame member Fs, first, two suspensions 5 and 5 are prepared. Then, the suspended bodies 6 in each of the suspended devices 5 are opened as indicated by phantom lines in FIG. 4, and the second attachment portions 6u are sequentially attached to the frame member Fs. Next, both sides in the width direction of the base body 3 are gripped by a pair of gripping portions 6dp,. At this time, since the relative position between the frame member Fs and the plant cultivation irradiation device 1 is fixed, the position of the suspended body 6... Is orthogonal to the other frame members Fs. Select an optimal position that does not interfere with either.

  And between the connection piece parts 6cp and 6cq is fixed by tightening the bolt nut 7w inserted in the bolt insertion holes 32p and 32q provided in the pair of connection piece parts 6cp and 6cq. As a result, the second mounting portion 6u is pressed onto the peripheral surface of the frame member Fs and fixed on the frame member Fs, and the gripping portions 6dp and 6dq of the first mounting portion 6d grip the base body 3 and It is fixed on the base body 3. FIG. 8 shows a state where each plant cultivation irradiation device 1 is attached to the frame member Fs of the cultivation shelf R. Moreover, if power is supplied to each irradiation device for plant cultivation 1 through the connection cable 17, each LED 2 emits light, and the mushroom cultivation bin Pb disposed on the lower shelf Rs... (Plant P to be cultivated) Can be irradiated.
