Provided is a light emitting unit which comprises: a plurality of light emitting diode arrays disposed on a circuit board and emitting light within a range of a first wavelength region; and a wavelength conversion member disposed by being separated from the light emitting diodes, emitting light within the range of a second wavelength region after being excited by the light within the range of the first wavelength region, and including a plurality of regions with different thicknesses. According to an embodiment of the present invention, the light emitting unit is intended to vary a color temperature of light emitted from a light source depending on a service environment of lighting fixtures. |
