Reflector for light has reflective region opposite light outlet opening so light emanating from or passing through emission point is reflected to at least one focal point near light outlet opening

摘要

The reflector has an emission focal point (22) enclosed over more than 180 degrees when viewed in cross-section to leave a light outlet opening (24) whose width is smaller than the internal dimension of the reflector. At least the region (23) of the reflector opposite the light outlet opening is reflective so that the light emanating from or passing through the emission point is reflected to at least one focal point (26) near the light outlet opening.
