Abstract
Provided is a light source device including a first light source, a light guiding system and a wavelength conversion device. The first light source emits first exciting light which is incident to the light guiding system along an incidence light channel. The wavelength conversion section absorbs the first exciting light and emits excited light. The first exciting light is obliquely incident to a surface of the reflective section and reflected to form second exciting light. The light guiding system collects the excited light and the second exciting light and guides them to be emitted along an exiting light channel. The light guiding system includes an optical path correcting assembly, which reflects the second exciting light in such a manner that main optical axes of the reflected second exciting light and the excited light coincide, and changes a beam angular distribution of the second exciting light.
