A mount assembly for supporting the arc tube of a lamp within an outer envelope has first and second axially aligned banding straps. Each of the straps has a closed crimp section and an open crimp section. The straps are positioned so that an open crimp section of one strap overlies a closed crimp section of the other strap, thereby equalizing tensions when the crimps are closed. The mount assembly includes also a mount frame comprised of two elongated rods which are affixed to the banding straps. The straps are mounted upon the glass stem of the lamp.

Mount assembly for arc lamp

A lamp mount assembly (9) includes: a centrally located glass stem (10) having a convex surface; upper and lower banding straps (11, 13) circumferentially encompassing, and crimped to, the centrally located glass stem (10), the banding straps (11, 13) each further comprising oppositely disposed crimp portions, a first of the crimp portions being an interlocking crimp portion (12a, 12b) and a second of the crimp portions being a solid crimp portion (13a), the interlocking crimp portion of the upper banding strap (11) overlying the solid crimp portion (13a) of the lower banding strap (13); and a pair of mount frames (14) disposed about the centrally located glass stem (10), the banding straps (11, 13) holding the mounting frames (14) in place about the glass stem (10), the mounting frames (14) having a coined, concave surface substantially matching the convex surface of the glass stem (10). The banding straps including oppositely disposed crimp portions, of the present invention, reduces breakage of the glass stem.
