Abstract: A lamp housing assembly is provided for mounting upon the facia of a motor vehicle. In one embodiment, the lamp housing assembly may be useful in housing and mounting a fog lamp to a motor vehicle. The lamp housing assembly includes a cup-shaped body having a key formed on the upper surface of the body. A mounting bracket is provided which includes a first portion having a keyway, which may be engaged with the key to attach the mounting bracket to the cup-shaped body. The mounting bracket also includes a second portion which extends beyond the cup-shaped body for attaching the mounting bracket to the facia.

Abstract: An EMI shielding lens for a lamp, e.g., an automotive lamp. The lens includes a transparent, unitary, polymeric lens blank and a thin, heat transferred grid layer including an electrically conductive grid pattern disposed on the lens blank inner or outer surface. The grid pattern may be formed from indium tin oxide or from a conductive, heat transferable, inks or polymer. The grid layer may also include colored or opaque indicia. Linear elements of the grid pattern are spaced apart by less than 1/2 .lambda. of the EMI to be shielded. Also discloseed is an electromagnetic interference shielded lamp assembly including an electrically conductive housing, a light source within the housing, the EMI shielding lens fixed to the housing, and grounding means. Methods for fabricating the lens and the lamp assembly are also disclosed.
