Abstract
A light source device has a first light source assembly. The first light source assembly has plural first light source sets. The first light source sets are arranged around a first central axis. Each of the first light source sets has a first excitation light source and a first reflecting element. The first reflecting element is disposed between the first excitation light source and the first central axis to reflect a first excitation light of the corresponding first excitation light source, and thereby forming a laser beam. A projection apparatus has an illumination system, an optical engine, and a projection lens. The illumination system has a light source device and a wavelength-converting wheel. The light source device and the illumination system may improve the utilization efficiency of the condenser lens.
