Claim 7:
8. A light exposure control device for irradiating a plant, comprising:
a set of visible light and infrared radiation sources configured to irradiate a surface of the plant with visible radiation and infrared radiation;
a set of ultraviolet radiation sources configured to spot irradiate the surface of the plant in a set of predetermined locations with a target ultraviolet radiation having a range of wavelengths, wherein each predetermined location is smaller than the surface of the plant;
a plurality of environmental condition sensors that detect conditions of the environment in which the plant is located during irradiation by the set of visible light and infrared radiation sources and the set of ultraviolet radiation sources; and
a controller configured to control irradiation of the surface of the plant by the set of visible light and infrared radiation sources and the set of ultraviolet radiation sources according to a plurality of predetermined optimal irradiation settings specified for various environmental conditions, wherein each predetermined location corresponds to a location on the surface of the of the plant determined to require supplemental irradiation with radiation having the range of wavelengths to induce a desired effect on the plant, wherein the controller directs the set of ultraviolet radiation sources to irradiate the set of predetermined locations on the surface of the plant with a first radiation having a distinct wavelength of emitted radiation at a predetermined intensity and duration, and at a second radiation having a wavelength of emitted radiation at a predetermined intensity and duration that is different from the first radiation, wherein the first radiation and second radiation are configured to induce fluorescence in the irradiated set of predetermined locations.
