    Abstract: A plant cultivation light source includes a substrate and a first group of light sources. The first group of light sources includes a plurality of light sources disposed on the substrate, and a light source including a light emitting structure including a first semiconductor layer, an active layer, and a second semiconductor layer. The plurality of light sources operates to emit lights having different wavelength bands and includes a first light source that emits first light having an area of at least about 55% compared with an area of a normalized solar spectrum, a second light source that emits second light having a wavelength for cryptochrome, and a third light source that emits third light having a wavelength for phytochrome.

    Abstract: Disclosed herein are a light source module for plant cultivation and a light device including the same. The light source module for plant cultivation may include at least one main light source emitting white light. The white light from the main light source is provided to a plant during cultivation to improve the growth and phytochemical content of the plant. In addition, the white light may have peak wavelengths of 430 nm or less, 440 nm to 460 nm, 510 nm to 530 nm, and 600 nm to 630 nm.

    Abstract: A plant cultivation light source includes a plurality of light sources configured to be turned on or turned off depending on a selected plant and a growth stage of the selected plant, and a controller. The controller is operable to turn on the light sources during a light period such that the light sources are operable to emit a light having a spectrum with a plurality of peaks to the selected plant. The light period including a first period and a second period and the first period preceding or following the second period. The controller is operable to adjust the spectrum of the light to alternate the first period and the second period during the light period.

    Abstract: A plant cultivation light source is turned on, or turned off depending on a light period and a dark period of a plant. When a portion of the light period is referred to as a first period and the other portion of the light period is referred to as a second period, the first period and the second period are alternately provided with each other, and lights having different wavelengths from each other are provided to the plant in the first and second periods, thereby increasing a content of an active ingredient in the plant.

    Abstract: A light source can include at least one light emitter and is configured to emit a first light during a region of a light period and emit both the first light and a second light of a different wavelength during a remaining region of the light period. The emitter can include semiconductor layers and an active layer configured to emit light having a specific wavelength due to a band gap difference in an energy band depending on a material used to form the active layer. A plant cultivation device can include the light source and a main body in which a plant can be grown. The light period can be configured to increase a content of an active ingredient in the plant. The first light can have a longer peak wavelength than a peak wavelength of the second light.

    Abstract: A light source includes a controller configured to turn on or off a plurality of light sources depending on a light period. The controller can be configured to turn on the light sources during each of a plurality of light periods such that the light sources emit a light having a spectrum with a plurality of peaks toward the plant. At least one light period can include a first period and a second period and the first period preceding or following the second period. The controller can adjust the spectrum of the light between the first period and the second period and/or during different light periods.
