1. A light ring assembly, comprising:
a circuit board having a plurality of light sources;
a light ring being a flat ring-shaped component made of an optical material and facing the plurality of light sources and having a bottom side with an optical input surface, a top side with an optical output surface, an inner periphery, an outer periphery, and a plurality of optical elements; and
a lens made of an optical material facing the top side of the light ring, wherein the light ring assembly is arranged so that light from the plurality of light sources enters the light ring at the optical input surface of the bottom side, is reflected and mixed within the light ring by the plurality of optical elements, and exits the light ring at the optical output surface of the top side so that it is directed towards the lens.
