Single-ended discharge lamp having an improved electrical connection arrangement

A low pressure discharge lamp comprising:

• a lamp envelope having an internal coating and fill contained therein;
• electrodes disposed within said lamp envelope;
• lead wires extending from said electrodes and through a sealed region of said lamp envelope;
• said lamp envelope being mounted on a base housing member, said base housing member further having a screw base mounted thereon, said screw base being receptive of line power;
• a ballast circuit arrangement disposed within said base housing member, said ballast circuit arrangement being receptive of such line power and effective so as to develop therefrom, an operating signal for driving said discharge lamp;
• at least two connector members mounted on a circuit board portion of said ballast circuit arrangement, each of said at least two connector members simultaneously mechanically and electrically connecting a corresponding one of said lead wires to said ballast circuit arrangement without a need of a solder joint;
• wherein said lead wires are mechanically secured to an interior wall portion of a cavity formed in each of said at least two connector members by means of a deformation joint;
• and,
• wherein said at least two connector members are cylindrical in shape and the cavity formed therein is a blind hole in which the lead wires are placed in the direction of the axis of said at least two connector members, and the electrode inlead is mechanically fixed in the blind hole by means of an indentation made in a direction perpendicular to the axis.
