Title:
LIGHT ENERGY TIME-DIVISION DISTRIBUTION DEVICE, PLANT FACTORY, BUILDING, AND LIGHT ENERGY TIME-DIVISION DISTRIBUTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/039066
Kind Code:
A1
Abstract:
Provided are: a light energy time-division distribution device with which light energy can be time-divided into three or more; a plant factory; a building; and a light energy time-division distribution method. A light energy time-division distribution device (100) according to the present invention is provided with a rotary barrel (101) and a light guide part (102). The rotary barrel (101) time-divides first incident light incident onto an outer circumferential surface (6) in a first incident direction into first reflected light and second reflected light, and time-divides, into third reflected light and fourth reflected light, second incident light incident onto the outer circumferential surface (6) in a second incident direction that is different from the first incident direction. The light guide part (102) receives and guides the first or second reflected light and cause the light to enter the rotary barrel (101) as the second incident light.
