Abstract
Provided is a light source device, including a first light source module configured to output a first light beam; a second light source module configured to output a second light beam, etendue of the first light beam being smaller than etendue of the second light beam; a polarization conversion system configured to receive the first light beam and the second light beam and perform polarization conversion on at least one of the first light beam the second light beam; and an etendue increasing module provided on a light path between the first light source module and the polarization conversion system and configured to increase the etendue of the first light beam. Etendue of the first light beam incident on the PCS increases and the optical power density of the first light beam incident on the PCS decreases, thereby preventing overheating from affecting reliability of the polarization conversion system.
