Based on a known design according to WO 2012 / 068603, which presents complete mixing of the LED light colors and has since been considered state of the art, limiting the number of chips used in the light sources and their arrangement reveals a previously unknown freedom in the design of the light guide and the upstream converging lens, and thus in the achievable light distribution.
