['1. A light source device, comprising a first light source, a fly-eye lens pair, a light guiding system, and a wavelength conversion device; wherein the first light source is configured to emit first exciting light which is homogenized by the fly-eye lens pair and then incident to the light guiding system; 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 different time divisions, 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; the light guiding system is further configured to collect the excited light and the second exciting light, and to guide the excited light and the second exciting light to exit along an exiting light channel; the light guiding system comprises an optical path correcting assembly 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 that of the excited light; and the fly-eye lens pair comprises a first lens array and a second lens array that are sequentially disposed along a direction of the first exciting light, wherein lens units constituting the first lens array are configured to perform imaging with overlap on a surface of the wavelength conversion device.', '3. The light source device according to claim 1, wherein the light guiding system further comprises a collecting lens for converging the first exciting light onto the wavelength conversion device and collecting the excited light and the second exciting light from the wavelength conversion device; and wherein a distance between an edge of a beam of the first exciting light incident to the collecting lens and a central axis of the collecting lens is in a range of 0.2 to 0.5 mm.']
