<p>A system (16) for illuminating a desired illumination region comprises a lamp (30) for providing illumination, a reflector (34) for reflecting a portion of the illumination towards said desired illumination region and a shield (32), selectively positioned between the lamp and the desired illumination region. The shield permits a portion of the illumination to pass directly from the lamp to the desired illumination region and redirects another portion of the illumination toward the reflector.</p> |
