A novel secondary optical design for LED lamps with high color rendering indices (CRI) and adjustable correlated color temperature (CCT) is proposed. RGB LED cells are assembled in a three dimensional manner together with a set of beam mixers. Perfect light mixing is resulted by optimizing the structural parameters of the reflectors and beam mixers. A… CONTINUE READING
