The reflector sections are formed with edges that mate with edges of an adjacent reflector section along seams to prevent light from showing through the seams. The mating edges preferably include light-blocking features formed by a geometric shape along the seams.

Abstract: An optical integrating cavity supplies light or other radiant energy through a port to a deflector. The deflector coupled to the port may form a “fan” extending along one side or around all or part of the circumference of the cavity. Preferred embodiments use principles of constructive occlusion (diffuse reflectivity in a mask and cavity structure) together with the port and deflector structure.

The first and second areas illuminated may overlap slightly, or one may include the other, but preferably most of the two areas are separate. In some cases, the system configuration creates a dead zone between the two regions.
