Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 197 words
Improved ballast circuit mounting means for use in a discharge lamp luminaire comprising in combination: (a) at least one ballast circuit component housed in a sealed container having top and bottom portions connected by side portions, with electrical terminal means being included in said top portion, (b) a mounting bracket to secure the container to a mounting surface in the discharge lamp luminaire so that its electrical terminals are upright with respect to the mounting surface, and (c) the mounting bracket having a deformable planar construction formed by a first planar section intersecting a second planar section, the first planar section being secured to the mounting surface by fastening means so as to exert a mechanical spring force upon the second planar section in a downward direction with respect to the mounting surface, and the second planar section having a central opening physically engaging the container side portions at an angle, whereby securing said fastening means to said mounting surface creates compression forces to cause said mounting bracket to deform and provide a rotational action upon said container which forces the container into said mounting surface so as to prevent movement between said container and mounting surface.
