Patent ID: 8905576

Claim:
An illumination source, comprising a reflector having an optical axis, intersecting a focus and a vertex of the reflector, wherein said reflector comprises a shape around the vertex at a center part of said reflector, the improvement comprising: an elongate mounting structure with a first end and a second end, said first end mounted adjacent a distal edge of said reflector distal to said vertex and outside said optical axis of said reflector, said second end extending toward said optical axis away from said distal edge, said second end intersecting said optical axis distal to said vertex; a first substantially hemispherical illumination source mounted centrally on said mounting structure, said first substantially hemispherical illumination source having a first source axis, said first substantially hemispherical illumination source being disposed adjacent said reflector and directed toward said reflector; wherein said first source axis and said optical axis form a first angle therebetween, said first angle being greater than zero degrees and less than 90 degrees; a second substantially hemispherical illumination source mounted centrally on said mounting structure, said second substantially hemispherical illumination source having a second source axis, said second substantially hemispherical illumination source being disposed adjacent said reflector and directed toward said reflector; wherein said second source axis and said optical axis form a second angle therebetween, said second angle being greater than zero degrees and less than 90 degrees; and, wherein said first substantially hemispherical illumination source and said second substantially hemispherical illumination source provide light falling on the center part of the reflector at the vertex.
