A light source unit includes a light source which emits a light bundle in one direction; a polarizing unit which is formed to selectively transmit a certain polarized light of a certain wavelength in the light bundle; and a reflection unit which is formed so as to delay the phase of the polarized light so that the polarized light is reflected by the polarizing unit, convert one part of the wavelength of the polarized light, and reflect the polarized light toward the polarizing unit.

A light source assembly includes a plurality of first light sources disposed on a first plane to emit light, a plurality of second light sources disposed on a second plane, the second plane spaced apart from the first plane with a preset interval, wherein each second light source emits light between the adjacent first light sources, and a lens configured to concentrate light emitted from the plurality of first and second light sources. A projector having the light source assembly is also provided.
