摘要 |
The invention is directed towards common focus energy emitters having a common focus energy source and including two or more energy source units each having a 3D concave primary reflector for reflecting energy into an energy beam focused at the common focus energy source, and a secondary optical element for shaping the energy beam into an exit beam component of the exit beam. The 3D concave primary reflectors bound a minor 3D concave section of an imaginary primary reflector ellipsoid of revolution having a primary reflector axis of revolution non-coaxial with the energy emitter axis. Each primary reflector axis of revolution includes a first focal point disposed at the common focus energy source and a second focal point where its associated energy source is disposed thereat. |
