Light reflector with defined acutance of the light distribution generated by the same

摘要

The reflector (1) has a reflection surface comprising a facet in sections, and a retainer (5) for an illuminant e.g. LED. The facet is provided with a cylindrical form in an illuminant close area (2), and is provided with a spherical form in an illuminant distant area (3). A periphery runs between the illuminant close and distant areas along an intersection line of a plane that runs perpendicular to a symmetric axis. The illuminant close area takes up between 20 to 35 percentages of the refection surface.
