Ring Light collector
First Claim
1. Light collector comprising:
- a light source;
a plurality of light pipes located in a fixed relation with said light source, each light pipe having a face, said faces collectively substantially forming a ring having a predetermined width between an inner diameter and an outer diameter; and
a concave reflecting surface fixed relative to said light source and said plurality of light pipes and having an axis of symmetry, said concave reflecting surface extending in a rotated ellipsoidal fashion defined by the outermost surface of an ellipsoid having a major axis forming a predetermined angle with said axis of symmetry, a first focal point located a predetermined distance from said axis of symmetry and a second focal point located substantially between the outer diameter and inner diameter of said ring, said major axis of said ellipsoid rotated about said axis of symmetry, said light source located substantially at said first focal point;
whereby light reflected from said concave reflecting surface forms a ring on said faces of said light pipes.

Abstract
A ring light collector having a light source with a plurality of light pipes is located in a fixed relation with the light source. Each light pipe has a face which collectively substantially form a ring having a predetermined width between an inner diameter and an outer diameter. A concave reflecting surface having an axis of symmetry is fixed relative to the light source and plurality of light pipes. The concave reflecting surface extends in a rotated ellipsoidal fashion and is defined by the outermost surface of an ellipsoid having a major axis forming a predetermined angle with the axis of symmetry. The major axis of the ellipsoid is rotated about the axis of symmetry. The first focal point of the ellipsoid is located a predetermined distance from said axis of symmetry and a second focal point is located substantially between the outer diameter and inner diameter of the ring. The light source is located substantially at the first focal point. The light reflected from the concave reflecting surface forms a ring on the faces of the light pipes.
