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.

Abstract: A sensor device for a transportation device includes a sensing apparatus for sensing first electromagnetic radiation having at least one first wavelength, and a covering device for the sensing apparatus. The covering device contains a fluorescent portion includes a fluorescent dye, which has an absorption spectrum and an emission spectrum. The fluorescent portion is transparent to the first electromagnetic radiation having the first wavelength. The fluorescent portion is configured such that, when irradiated with second electromagnetic radiation having a second wavelength in the absorption spectrum of the fluorescent dye, the fluorescent portion emits third electromagnetic radiation in the emission spectrum. The first wavelength and the second wavelength are different.
