A light distributor, a system consisting of a light distributor and an LED luminaire, and a method for producing a light distributor are provided. The light distributor may include a transparent main body having a light entrance area and a light exit area, at least one light-scattering structure with a changed refractive index inside the main body for scattering light, and at least one light-guiding structure with a changed refractive index inside the main body for guiding light. The light-scattering structure and the light-guiding structure may be produced by means of ultrashort pulse laser processing. The light-scattering structure and the light-guiding structure with a changed refractive index may be arranged in the main body.
