Illuminating device for plant factory, has control unit that outputs light-modulation output signal to drive unit, so that optical intensity of light emitted by lamp and LED unit is adjusted based on light-modulation output signal

摘要

A drive unit drives the cold cathode fluorescent lamp (41) and LED unit (42), so that light of specific wavelength is emitted from cold cathode fluorescent lamp and LED unit. A light control unit is connected to drive unit for outputting the light-modulation output signal with respect to drive unit, so that optical intensity of light emitted by cold cathode fluorescent lamp and LED unit is adjusted based on light-modulation output signal.
