ABSTRACT:
To provide an illuminator for plant growth that can illuminate a plant intermittently (pulse illumination) or continuously to cause an effect similar to sunbeam spot phenomenon, thereby accelerating photosynthetic reaction.Specifically, the illuminator for plant growth includes a light source composed of a semiconductor optical device, a control unit for outputting a turn-on timing signal for the light source, a rhythm signal detecting unit for A/D converting an input rhythm signal, a timing signal modulating unit for modulating the turn-on timing signal with the output signal from the rhythm signal detecting unit, and a pulse drive unit for pulse-modulating a power signal with the modulated turn-on timing signal outputted from the timing signal modulating unit and supplying the pulse-modulated power signal to the light source.
