['1. A light source device, comprising a first light source, a light guiding system, and a wavelength conversion device; wherein the first light source is configured to emit first exciting light, and the first exciting light is incident to the light guiding system along an incidence light channel; the light guiding system is configured to guide the first exciting light to the wavelength conversion device; the wavelength conversion device comprises a wavelength conversion section and a reflective section, and periodically moves in such a manner that the wavelength conversion section and the reflective section are periodically located on an optical path of the first exciting light in time division, wherein the wavelength conversion section absorbs the first exciting light and emits excited light, and the first exciting light is obliquely incident to a surface of the reflective section and is reflected to form second exciting light; and the light guiding system is further configured to collect the excited light and the second exciting light and guide the excited light and the second exciting light to exit along an exiting light channel; wherein the light guiding system comprises an optical path correcting assembly, which is located on an optical path of the second exciting light and configured to reflect the second exciting light in such a manner that a main optical axis of the reflected second exciting light coincides with a main optical axis of the excited light and further to change a beam angular distribution of the second exciting light in such a manner that imaging positions of the second exciting light and the excited light coincide in a direction of beam propagation.', '9. The light source device according to any one of claims 4, 5, 7 or 8, wherein the light source device further comprises a second light source configured to emit compensation light when the wavelength conversion section is located on the optical path of the first exciting  light, wherein a wavelength range of the compensation light overlaps with that of the excited light, and wherein the first light splitting assembly comprises a compensation light guiding region for guiding the compensation light to the wavelength conversion device.']
