Paper Abstract

Light from several LEDs or other light sources may be combined using light guides shaped as manifolds. These manifolds are composed of smaller elements such as CPCs, angle transformers, angle rotators, light shifters, light guides or others. Although some components, such as CPCs or angle transformers, have all-optical surfaces, other devices may be designed with non-optical surfaces. These may be used to place the injection gate in the case of injection-molded optics, to attach handles or holders and other non-optical components to the manifold without affecting the optical performance. Also, in some of these devices, the geometry can be changed by simple changes in the position of the curves that compose the optic profile. These optics may be applied in efficiently combining light from several LEDs into one single large source, changing the aspect ratio of a light source or in distributing light from one (or more) sources onto several targets.
