Light energy time-division distribution device, plant factory, building and light energy time-division distribution method

摘要

PROBLEM TO BE SOLVED: To provide a light energy time division distribution device, a plant factory, a building and a light energy time division distribution method capable of time-dividing light energy into 3 or more. A light energy time division multiplexing device 100 according to the present invention includes a rotary cylinder 101 and a light guide unit 102. The rotating cylinder 101 time-divides the first incident light incident on the outer peripheral surface 6 from the first incident direction into the first reflected light and the second reflected light, and from the second incident direction different from the first incident direction, The second incident light incident on the outer peripheral surface 6 is time-divided into a third reflected light and a fourth reflected light. The light guide unit 102 receives the first or second reflected light to guide the light, and causes the light guide to enter the rotating cylinder 101 as the second incident light.
