Structure for reflection of light

A structure for collecting light comprising:

• a first curved surface reflector for reflecting the light emitted from a first light source located on a first focus of the first curved surface reflector;
• a second curved surface reflector for reflecting the light emitted from a second light source located on a first focus of the second curved surface reflector;
• a first semi-sphere surface for reflecting the light emitted from the first light source located on a center of the first semi-sphere surface;
• and
• a second semi-sphere surface for reflecting the light emitted from the second light source located on a center of the second semi-sphere surface;
• wherein the first focus of the first curved surface reflector and the center of the first semi-sphere surfaces are so positioned as to be substantially on a first location, and the first focus of the second curved surface reflector and the center of the second semi-sphere surfaces are so positioned as to be substantially on a second location, and
• wherein after the light emitted from the first and second light sources is reflected by the first and second semi-sphere surfaces, respectively, the reflected light pass through the respective centers to illuminate on the first and second curved surface reflectors, respectively, so that all of the light reflected by the first and second semi-sphere surfaces can pass through the respective centers to illuminate on the respective curved surface reflector, be reflected by the same, then be condensed on a second focus.
