METHOD FOR ILLUMINATION FOR FRUIT GROWING IN GREENHOUSE, ILLUMINATOR AND ILLUMINATING APPARATUS

PURPOSE:To obtain a method for effectively supplementing the light to a fruit tree with a few illuminating tools and its apparatus. CONSTITUTION:Each rotatable illuminating tool 2 equipped with a microcomputer and a memory means is arranged between fruit trees in a greenhouse and the surrounding trees are successively illuminated with light from the illuminating tool while automatically rotating based on data previously inputted to the memory means. This illuminating tool 2 is provided with a rotatable body 15, supports 10, supporting a reflecting mirror 11 and rotatably attached to the body so as to enable a change in irradiating angle, a driving mechanism for rotating and revolving the body and supports, a microcomputer for controlling the driving mechanism and a memory means memorizing data on the rotation and revolution of the body and supports. The plural illuminating tools 2 are arranged between the fruit trees in the greenhouse where the plural fruit trees are planted, connected to a central controller 3 and controlled.
