Abstract: A light device for plant cultivation is disclosed. The light device for plant cultivation includes a light source unit including multiple first light source modules and multiple second light source modules. The multiple first light source modules and the multiple second light source modules may emit light for plant cultivation toward a plant. The multiple first light source modules are arranged at constant intervals. The multiple second light source modules are disposed at least between a pair of first light source modules disposed at both ends of the light source unit.

Abstract: A plant cultivation light module includes a first light source, a second light source, and a controller. The first light source includes a first light emitter configured to emit first light having peak wavelength in a visible range and second light emitter configured to emit second light having a longer peak wavelength to the first light. The second light source includes a plurality of third light emitters configured to emit third light having a shorter peak wavelength to the first light. The controller is configured to control the first light emitter, the second light emitter and the plurality of third light emitters and provide a first light pattern and a second light pattern. The first light source supplies light of the first light pattern and the second light source supplies light of the second pattern to the plant, respectively.

Abstract: A plant cultivation light source includes a first light source emitting a first light in a first wavelength band and a second light source emitting a first light in a second wavelength band different from the first wavelength band. The second wavelength band includes an ultraviolet light wavelength band, and the second light source is driven independently of the first light source to determine whether to emit the second light while the first light source emits the first light.
