Abstract
A light source system includes a laser light source, a transflective optical component, a set of first lenses, a scattering surface, a set of second lenses, an excited light generator, a relay lens, an aperture, and a lens. The laser light source generates light in the first wavelength range irradiating onto the transflective optical component. The transflective optical component reflects a part of the light in the first wavelength range to form first light and transmits a part of the light in the first wavelength range to form second light. The scattered light formed by the first light being scattered on the scattering surface is of uniformly distributed light intensity and converges with the light in the second wavelength range generated by the excited light generator under excitation of the second light to form output light, which is of uniform brightness. A light source adjusting method is further provided.
