Abstract
A recessed ceiling light fixture is provided that includes a reflector with multiple ellipsoidal segments. Each ellipsoidal segment reflects light through a common focal point or area. Reflecting the light of each ellipsoidal segment through a common focal point or area, only a very narrow aperture is required. Further, improved light distribution and improved space to mounting height ratios are also provided by using a reflector with multiple ellipsoidal segments.
