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.
