A state of the art pilot-scale plant-factory, planned for research, was constructed at Tamagawa University in Tokyo, Japan. The full research facility, named Future Science Technology Center, has been operational since March 2010. The plant-factory facility is housed on the first floor of the research center. In this presentation, the plant factory facility design will be discussed as well as the facilities planned utilization of artificial lighting sources, such as Light-emitting Diodes (LEDs), Hybrid Electrode Fluorescent Lamps (HEFLs) and cool white fluorescent (CWF) lamps for plant production. The main component of the artificial lighting source is liquid cooled Chip on Board (COB) high intensity LED panels. The COB utilizes AlGaInP/GaP-based LEDs with a peak wavelength of 660 nm. Various COB and Package on Board (POB) LED panel designs were tested prior to the construction of the facility.
