Claim 0:
1. A light source system, comprising:
a first light-emitting assembly configured to generate at least one primary light;
a second light-emitting assembly configured to generate excitation light;
a wavelength conversion device at least partially provided on an optical path of the excitation light and configured to receive the excitation light and generate excited light;
an optical assembly provided on an optical path of the excited light and configured to increase etendue of the excited light before light combination of the at least one primary light and the excited light, to improve a ratio of etendue of the excited light to etendue of the at least one primary light and reduce loss of the excited light during the light combination; and
a light combination device provided on a common optical path of the at least one primary light and the excited light, located behind the optical assembly, and configured to combine the at least one primary light and the excited light.
