Claims27
An energy directing system, comprising:
- an energy surface comprising a plurality of energy source locations;
- and
- an array of energy waveguides, each waveguide configured to direct energy along different propagation paths from different energy locations of the energy surfaces, wherein each propagation path has a four-dimensional coordinate, the four-dimensional coordinate comprising two spatial coordinates corresponding to a location of the respective energy waveguide and two angular coordinates determined at least in part by the energy source location relative to the respective waveguide, the angular coordinates defining the direction of the respective propagation path;
- wherein the propagation paths of each waveguide are grouped around an energy propagation axis that defines an axis of symmetry with respect to an angular range of the propagation paths of the respective waveguide;
- and
- wherein the array of energy waveguides define an energy directing surface and comprise a first waveguide having a first energy propagation axis and a second waveguide having a second energy propagation axis, the first and second energy propagation axes form first and second deflection angles, respectively, relative to a normal of the energy directing surface, and further wherein the first and second deflection angles are different;
- and
- an optical element disposed in the propagation paths of at least the first or the second energy waveguide of the array of energy waveguides, the optical element configured to receive energy along the propagation paths of the first or the second energy waveguide and redirect energy along a plurality of deflected propagation paths, the plurality of deflected propagation paths and the plurality of propagation paths of the first or the second energy waveguides forming non-zero deflection angles therebetween,
- wherein the optical element comprises a first surface facing towards the array of waveguides and a second surface facing away from the array of waveguides,
- wherein at least one of the first and second surfaces, or both are faceted.
