Classification: CPC A  H | IPC A  H

Claim 14:
15. An on/off type light source module for plant cultivation, comprising:
a light source comprising:
a first semiconductor layer doped with a first conductivity type dopant;
a second semiconductor layer disposed on the first semiconductor layer and doped with a second conductivity type dopant different from the first conductivity type dopant; and
an active layer interposed between the first semiconductor layer and the second semiconductor layer; and

a controller configured to operate the light source to adjust wavelength, radiation intensity, emission timing, or a combination thereof, of the light source, to control a type and a content of a phytochemical in a plant, wherein the controller varies operation of the light source based on data indicating a type of the plant, a desired size of the plant, and a growth stage of the plant, and wherein the operation is varied such that the light source emits a first type of light in a first condition that is selected to increase the content of the phytochemical in the plant without encouraging additional plant growth, and the light source emits a second type of light in a second condition that is selected to increase the content of the phytochemical in the plant and encourage additional plant growth.
