Patent ID: 8246212

Claim:
An LED luminaire comprising: a heatsink; a support surface in thermal connectivity with said heatsink, said support surface having a plurality of light emitting diodes mounted thereto, said light emitting diodes electrically connected to a power source, each of said light emitting diodes having a light output axis oriented outward and away from said support surface; a plurality of reflectors mountable over said support surface, each of said reflectors positioned over one of said plurality of light emitting diodes and being a bi-focal reflector with a first reflector portion having a first curvature and a second reflector portion having a second curvature, said first curvature being a more gradual curvature 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 said support surface than said second focal point; a plurality of optical lenses, each of said optical lenses positioned over one of said plurality of reflectors; wherein at least a single optical lens of said plurality of optical lenses has at least one cutoff prism positioned over said first reflector portion of a single reflector of said reflectors and a single light emitting diode of said light emitting diodes, said cutoff prism extending in a direction outward and away from said support surface; wherein said single optical lens has a non-prismatic outer face positioned over said second reflector portion of said single reflector, said non-prismatic outer face of said single optical lens facing outward and away from said support surface; and wherein light output from said single light emitting diode that is incident on said cutoff prism is asymmetrically redirected out of said cutoff prism.
