Abstract
A defocused optic () for mixing of light output from a multichip LED (). The defocused optic () includes an outer reflector having a concave inner surface () with a varied profile. The outer reflector surrounds an interior reflector () having a convex surface (). The convex surface () of the interior reflector () is positioned to generally face a multichip LED () and may optionally have a varied profile. Appropriate selection of the design parameters of the profiles of the concave inner surface (), the profile(s) of the convex surface (), and the rotational angular range over which said profiles are present enables appropriate mixing of the light output from a given multi-chip LED ().
