Patent ID: 8672519

Claim:
An LED optical assembly, comprising: a support surface, said support surface having a light emitting diode mounted thereto, said light emitting diode having a light output axis oriented outward and away from said support surface; a reflector mountable over said support surface, said reflector positioned over said light emitting diode and being a bi-focal reflector with a first reflector portion with a first curvature and a second reflector portion with a second curvature, said first curvature being more gradual than said second curvature, said first reflector portion having a first focal point and said second reflector portion having a second focal point, said first focal point being more proximal to said support surface than said second focal point; an optical lens, said optical lens covering said reflector; wherein said optical lens has an inner surface, said inner surface generally facing said reflector; wherein said optical lens has an outer surface, said outer surface generally facing away from said reflector, said outer surface having a first outer area and a second outer area, said first outer area positioned over said first reflector portion, said second outer area positioned over said second reflector portion; wherein a cutoff prism extends from said first outer area in a direction away from said support surface; wherein said second outer area is non-prismatic; and wherein light output from said light emitting diode that is incident on said cutoff prism is asymmetrically directed out of said cutoff prism.
