Claim 7:
8. A plant cultivation device, comprising:
a panel;
a container for growing of a plant; and
a light emitting module disposed on the panel, the light emitting module comprises:
a base;
a first light emitter disposed on the base and comprising a first light emitting diode emitting a primary light and a converter disposed on a path of the primary light emitted from the first light emitting diode to produce a first light; and
a second light emitter disposed on the base and comprising a second light emitting diode emitting a second light having a different peak wavelength from the first light,

wherein combined light emitted from the first light emitter and the second light emitter produces a basic spectrum,
wherein the basic spectrum includes at least a first peak wavelength, a second peak wavelength, and a third peak wavelength,
wherein the second peak wavelength is between and adjacent to the first peak wavelength and the third peak wavelength,
wherein the second peak wavelength has a wider spectrum than the spectrum for at least one of the first peak wavelength or the third peak wavelength,
wherein one of the first peak wavelength or the third peak wavelength is in the blue spectrum and the other of the first peak wavelength or the third peak wavelength is in the red spectrum, and
wherein a difference between a relative intensity of the second peak wavelength and a relative intensity of at least one of: the first peak wavelength or the third peak wavelength is less than 20%, and
wherein the combined light is irradiated toward the plant.
