A cap for securing a plurality of discharge tubes to a discharge lamp assembly includes a pair of ribs formed on a base plate of the cap. The ribs guide adhesive towards openings in the base plate through which the tubes extend. Adhesive is kept away from the base plate perimeter, which may include a rim, such that assembly of the cap with a housing does not upset the adhesive bond securing the discharge tubes to the cap. Similarly, an assembly method for the cap involves the step of forming a pair of ribs on the base plate of the cap.

A fluorescent lamp includes a lamp tube having first and second ends and containing fill materials for causing light generation when provided with electrical power. The lamp further includes first and second power-transferring means at the first and second ends of the lamp tube, respectively, for providing the fill materials in the lamp tube with electrical power. Also included is a thermal heat shield separating the first power-transferring means from ballast circuitry which supplies power to the first power-transferring means and which has a lifetime that becomes substantially less as its operating temperature increases. The thermal heat shield is constructed so that it reflects back to the first power-transferring means and any adjacent portion of the lamp tube sufficient radiant energy to reduce the operating temperature of the ballast circuitry by more than about one degree Celsius compared with the absence of the heat shield.

A lamp cathode-to-ballast interconnect is provided in combination with a lamp having elongated cathodes and ballast circuitry for supplying power to the cathodes. The lamp cathode-to-ballast interconnect comprises a plurality of conductive clips connected to the ballast circuitry. Each clip has a generally flat portion connected at a first end to ballast circuitry and has a pinching groove formed through the flat portion and extending to a cathode-receiving opening at a second end. The interconnect further comprises a loom for holding the lamp cathodes. The loom comprises, for each cathode, a pair of cathode-receiving support grooves separated by a space in which a second end of an associated conductive clip is to be received. Walls of each of the pair of cathode-receiving support grooves grip therein-received portions of the cathode with sufficient force to enable a gas-tight contact to be made with its associated conductive clip when the cathode is received within the pinching groove of the clip. In a method of connecting elongated cathodes from a lamp to ballast circuitry for a lamp, the cathodes are gripped and inserted by machine implementation into respective pairs of cathode-receiving support grooves of the loom. A conductive clip is moved into a respective clip-receiving space in the loom so that the pinching groove of the clip receives and pinches a cathode and completes a gas-tight connection between the clip and the cathode.

A lamp assembly includes an inner assembly that has a CFL source, an electronics board, and a holder that interconnects the CFL source and electronics board. An outer, light transmissive envelope surrounds the inner assembly and various fixing arrangements are disclosed for securing the inner assembly to the outer envelope. Three primary mechanisms are a ratchet mechanism, a spring mechanism, or using adhesive to secure the inner assembly to the outer envelope under a predetermined tension.

The lamp is enclosed in an outer envelope comprising a substantially spherical portion enclosing the tube arrangement and an elongated end portion enclosing the ballast circuit. The end portion of the outer envelope is closed and sealed by a sealing means of the same material as the material of the outer envelope. The sealing means is connected to the envelope in a hermetically sealing way. A method for manufacturing a compact fluorescent lamp as described above is also disclosed. In the method, an outer envelope with an open end on the base side is provided. The open end of the envelope is closed and sealed with a sealing means to provide a hermetic seal. The envelope is separated by cutting along a circumferential line into an upper part and a lower part. The ballast circuit is introduced into the lower part and respective connection points of the ballast circuit are connected to power supply lead-out wires. The discharge tube arrangement is connected to respective connection points of the ballast circuit by lead-in wires. The lead-in wires and the lead-out wires are short and need not be insulated. The ballast circuit and the discharge tube arrangement are held and supported in the outer envelope by the connecting wires and fixing means.

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).
