Abstract
This invention relates to compact fluorescent lamps, and, more particularly, to the construction of connections inside the compact fluorescent lamp. The compact fluorescent lamp has a base (24), the base is connected to a housing (26) including a ballast circuit (18). The housing (26) is separated from the fluorescent tube (28) by a cap (20) on the side of the housing opposite to the base (24) and current feedthrough wires (2, 4) protrude from the fluorescent tube (28) inside the housing (26). The electrical connections between the current feedthrough wires (2, 4) and the lead-out wires (3, 5) of the ballast circuit and/or the junction lead-out wires of the base (24) are made by welding the corresponding wires together through metal connection elements (14).
