Abstract
An adhesively sealed beam lamp unit including a lens and reflector preferably having substantially rectangular peripheries and cooperating and opposing sealing surfaces located approximately about the lens and reflector peripheries. Contact between the lens and reflector sealing surfaces is limited to one or more portions along the sides thereof. Additionally reservoirs, located adjacent to the sealing surfaces restrict excess adhesive from spreading onto areas affecting lamp unit optical performance, outer dimensions, and integrity.
Claims9
A sealed beam lamp unit comprising a lens and reflector having substantially polygonal peripheries and cooperating and opposing planar sealing surfaces characterized by sides and corners, located approximately about said peripheries and with said planar sealing surfaces being in physical contact along the sides but spaced apart at the corners, with adhesive disposed on and between said planar sealing surfaces wherein a first of said planar sealing surfaces has corners protruding from a plane defined by the sides thereof and cooperating and opposing corners of a second of said planar sealing surfaces, said second planar sealing surface corners indented from a plane defined by the sides thereof, and with each side of said planar sealing surfaces further including reservoirs to contain excess adhesive.
