Abstract
A light source module for plant cultivation includes a main light source, an auxiliary light source unit, and a controller. The main light source unit emits background light which is visible light for growth of a plant. The auxiliary light source unit emits auxiliary light including UVB, UVC, or both to increase the content of phytochemicals in the plant. The controller controls operation of the main light source unit and the auxiliary light source unit based on a control signal.
Claims20
A light apparatus, comprising:
- a substrate;
- a main light emitter disposed on the substrate and configured to emit a main light having a first peak wavelength and a second peak wavelength;
- an auxiliary light emitter disposed on the substrate and configured to emit an auxiliary light having a peak wavelength that is different from the first peak wavelength or the second peak wavelength;
- and
- a printed circuit disposed on the substrate and electrically connected to the main light emitter and the auxiliary light emitter,
- wherein the peak wavelength of the auxiliary light is shorter than the first peak wavelength,
- wherein the main light emitter is configured to supply a background light during a light period and the auxiliary light emitter is configured to supply the auxiliary light during the light period, and
- wherein a light dose of the auxiliary light emitted from the auxiliary light emitter is different from a light dose of the main light emitted from the main light emitter during a same duration.
