LD-7490 ABSTRACT OF THE DISCLOSURE An improved pressed glass lens member for a sealed beam lamp unit is provided to include an outer sealing rim of varying thickness to compensate for thermal contraction of the lens member when molded in a predetermined manner. Specifically, the ordinary warped condition encountered with thermal contraction of the pressed glass article when initially formed is compensated for so as to permit subsequent heat sealing with a pressed glass reflector member by thermally fusing the glass material of both members in the sealing regions and without encountering the manufacturing defects now being experienced. The preferred embodiments illustrate such controlled thickness variation of the body section in the outer sealing rim region of a pressed glass lens member for both circular-shaped and rectangular-shaped lens con- figurations. Additionally, the rectangular-shaped pressed glass lens member embodiment illustrated can further include a molded projection provided on the back sealing surface of the rim region to further reduce unwanted deformation which otherwise occurs when the lens member is initially formed by pressing in glass molds.
