摘要： 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.

摘要： A light source system includes an excitation light unit, a spectral filter unit, a scattering unit, and an excited-light unit. The excitation light unit is configured to emit excitation light. In an embodiment, the spectral filter unit reflects a portion of the excitation light to the scattering unit, the scattering unit scatters the same to generate a first light and a second light, and the spectral filter unit transmits the second light. The spectral filter unit also transmits another part of the excitation light to the excited-light unit, the excited-light unit emits excited light under the illumination thereof, and the spectral filter unit reflects the excited light, so that the spectral filter unit merges and emits the transmitted second light and the reflected excited light. The excitation light is thus split into two paths at the spectral filter unit, and finally emits light by combining excitation light and excited light.
