Abstract
Rotational lighting system for plant factory is the way to decrease high installation cost of the existing lighting system. A few of LEDs are used at the rotational lighting system in comparison with the existing lighting system to supply artificial lights to crops. At rotational lighting system, the manufacturing cost becomes very low by comparing with the existing lighting system. In this paper, the photosynthetic photon flux (PPF) is investigated in order that plants may grow. And PPF is analyzed with the rotational speed of blade and LED output by using the rotational lighting system prototype and quantum sensor. It is confirmed that constant PPF value of $200{\mu}mol{\cdot}m^{^-2}{\cdot}s^{^-1}$ is supplied with the blade rotation speed of 20rpm and LED output of IN 73%, CENTER 37% and OUT 50%. By comparing with the lighting system of existing plant factory, there is no difficulty to supply the light needed to grow plants by rotating a few of LEDs.
