    摘要： A light source unit includes an excitation light source and a luminescent wheel on which luminescent light emitting areas including, on a reflecting surface, red and green luminescent materials which respectively emit light of red and green wavelength band, when receiving excitation light, and a diffuse transmission area which diffuses and transmits excitation light, are aligned end to end in a circumferential direction. An excitation light incident surface of a luminescent material layer of the luminescent wheel has a surface with a plurality of projecting bodies. Regular quadrangular pyramids are arranged thereon in a matrix with outer boundaries of bottom portions of adjacent regular quadrangular pyramids contacting each other. The pyramids rise at a rising angle of at least 30°, and a length of one side of an outer boundary of the bottom portion of the pyramid is between 10 and 100 μm.
