Abstract
A lighting device including at least one first light source configured to emit a visible light through a first light emitting surface, at least one second light source spaced apart from the first light source and configured to emit light having a wavelength for sterilization through a second light emitting surface, and a housing having a bottom portion, on which the first and second light sources are disposed. The housing can include at least one sidewall portion connected to the bottom portion to enclose the first light source and the second light source in one common area, in which the first and second light emitting surfaces face substantially the same direction, and both the first light emitting surface and the second light emitting surface can be disposed at a different elevation from the bottom portion of the housing.
