Abstract
A light source for plant cultivation includes at least two light emitting devices supplying light to a plant. Each of the light emitting devices includes 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. The light emitting devices emit light towards the plant under a different condition in terms of at least one of wavelength, radiation intensity, and emission timing to control the type and content of phytochemicals in the plant.
