ABSTRACT:
A conical deflector receives light from a source through an opening at the narrow end of the cone. In one embodiment, an optical fiber bundle supplies light directly into the cone. In another embodiment, the conical deflector receives light via an optical integrating cavity. A substantial portion of the inner surface of the cones has a specular reflectivity. The entire surface may be uniformly specular (e.g., highly specular). Alternatively, one or more sections of the inner walls of the cone may have a diffuse reflectivity or a different degree of specular reflectivity (e.g., quasi-specular). The deflector is dimensioned relative to a narrow, desired field of view and the light source to deflect light that would otherwise pass out of the desired field of view, so as to efficiently illuminate the desired field of view. The conical deflector provides a substantially uniform light intensity distribution over the desired field of view.
