Patent ID: 8858036

Claim:
A light fixture providing a desired spot light pattern diameter at a given distance, comprising: a planar light emitter providing a light source, forming a first plane, and defining a centroid of the light source; a first conical frustum reflector having a proximate end coplanar with the first plane, and a distal end; and a second conical frustum reflector located concentrically within the first conical frustum reflector and having a proximate and distal end, the proximate end being distal of the first plane and having a diameter smaller than a diameter of the distal end; the proximate end of the second conical frustum reflector is located at an intersection with a surface of a first hypothetical cone having a vertex at the centroid of the light source and the first hypothetical cone surface further intersecting the distal end of the first conical frustum reflector; the distal end of the second conical frustum reflector is located at an intersection with a surface of a second hypothetical cone having a vertex at the centroid of the light source and the second hypothetical cone surface further intersecting the desired spot light pattern diameter at the given distance; and wherein the combination of the first and second conical frustum reflectors directs the light source to the desired spot light pattern diameter at the given distance.
