A light source unit for a car lamp. The light source unit includes a substrate including wiring electrodes; a plurality of semiconductor light emitting devices electrically connected to the wiring electrodes; a plurality of phosphor portions spaced apart at preset intervals and arranged along rows and columns, and respectively disposed between the semiconductor light emitting devices so as to convert light emitted by surrounding semiconductor light emitting devices into second light having a second wavelength and to emit the second light; a light transmitting material filled between the phosphor portions and emitting first light having a first wavelength; and a color filter covering the phosphor portions and the light transmitting material and emitting the first light with the first wavelength and the second light with the second wavelength.
