Abstract
A reflector assembly for a low voltage incandescent bulb includes a reflector housing that defines a reflector cavity. A bulb socket holds an incandescent bulb in the cavity so that the bulb filament is positioned wholly within the cavity. The cavity has a glossy white, semireflective surface throughout with the exception of a reflective, mirrored strip having a matte finish that extends from a location inwardly of the bulb filament and adjacent the bulb socket, behind the filament, and down one wall of the cavity to a location adjacent the cavity opening. This reflective structure unexpectedly increases the diffused light output of the assembly by on the order of 40%.
