Abstract
A rectangular or other polygonal shaped lamp, such as a headlamp, comprising a lens member sealed to a reflector member. The lens member is provided with a rearwardly projecting polygonal rim having a surface which fits against and is sealed to a front rim of the reflector unit. The reflector front rim is provided with frontwardly projecting positioning members near at least two diagonally opposite corners, which fit inside corresponding corners of the lens rim for aligning the lens and reflector members together during sealing.
Claims2
A rectangular shaped all glass lamp comprising a rectangular shaped glass lens member adhesively sealed directly to a correspondingly shaped front of a glass reflector member by cooperating and opposing flat planar sealing surfaces, said lens member being provided with a flat planar surface rim extending toward and substantially against a flat planar mating surface of the reflector member, said reflector member being provided with integral positioning members extending therefrom only at each corner thereof and fitting inside by direct physical abutment with the corners of said extending rim to align the lens and reflector members together, and with said positioning members being spaced apart from the planar sealing surface of said lens member to limit residual stresses to the corner regions when said lens and reflector members are sealed together.
