Abstract

A light source unit for plant cultivation includes: a first light emitter emitting a primary light and a converter disposed on a path of the primary light to produce a first light, and a second light emitter emitting a second light, wherein combined light emitted from the first light emitter and the second light emitter produces a basic spectrum including at least three peak wavelengths, with a difference between relative intensities of at least two of the peak wavelengths being less than 20%.

First claim

What is claimed is:

1 . A light emitting module, comprising:
a substrate configured to electrically connect to an external power supply; a first light emitter disposed on the substrate and including a first light emitting diode configured to emit 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 substrate and including a second light emitting diode configured to emit a second light having a peak wavelength that is different from a peak wavelength of the primary 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 spectrum that is wider than a 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 a blue spectrum and another one of the first peak wavelength or the third peak wavelength is in a red spectrum, and wherein a difference between a relative intensity of the second peak wavelength and a relative intensity of the first peak wavelength is different from a difference between the relative intensity of the second peak wavelength and a relative intensity of the third peak wavelength.
