ABSTRACT:
The mirror assembly uses a reflective coating as a heating element for preventing fog formation on a mirror exposed to a humid environment such as is found in a bathroom. As compared to other typically reflective mirror coatings, the coating used in this invention has a relatively high resistance. The coating may be split into separate conductive elements with one or more scribe lines in order to control the length of the conductive path from inlet bus to outlet bus. The buses are made from an ultra thin foil tape which can be adhered to the reflective coating and which is solderable for securement of power lines thereto. The bus tape possesses both in plane and through plane conductive characteristics and can simply be cut to any length desired for the mirror sizes being produced. Power levels supplied to the mirror assembly are varied, with the initial level being higher so as to heat up the mirror quickly, and the maintenance level, which follows, being lower whereby mirror temperature can be maintained without producing an undesirable high mirror temperature. Power change is accomplished by a simple switch. If needed, the mirror assembly can possess a high degree of reflectivity.
