Abstract: A lamp assembly includes a sealed lamp envelope enclosing a filament, a screw shell connected to the lower portion of the envelope, and electrical leads extending from the filament into the screw shell. The screw shell has a bottom opening, in which is mounted an electronic control module. The electronic module is retained in the screw shell by an insulator. A spring is compressed between the electronic module and an exhaust tube on the lower portion of the envelope. One electrical lead is electrically coupled from the module through the spring to the filament, allowing the module to control the filament. The insulator defines a cavity for retention of the electronic module in a fixed position.

Abstract: To simplify assembly of a bottom portion (4) with a cap portion (3) of a base to a compact fluorescent lamp, and permit automated assembly thereof, the cap portion is formed with inner axially extending projections (23-26), and current supply leads (27a-28b) are looped about the axially extending projections. A circuit board (8) located transversely across the bottom portion (4) has essentially U-shaped bow frames or arched or clip elements (35-38) located thereon which are positioned to engage by resilient surface contact with the end portions (31) of the current supply leads when the bottom portion and the cap portion are snapped together upon axial movement. Inwardly extending ribs (44, 45; 48, 49) projecting from the inner wall of the bottom portion support the bow frame or arched or clip elements, and ensure prestressed reliable contact engagement between the bow frame or arched or clip elements and the end portions of the current supply leads.

Abstract: The present invention is for a small electrical light emitting device or socket to have two special electrical connector members. Each of the two special connector members is made of a generally rectangular shaped small and thin conducting plate having a narrow slit defined by two sharp inner edges of the plate. When a portion of an electrical wire having a conducting core and insulating cover is inserted into the narrow slit, the two sharp inner edges of the conducting plate will automatically strip off the insulating cover of the wire immediately adjacent to the slit and thus contact the conducting core of the wire to thereby establish an electrical connection between the wire and the light emitting device or its socket. A desirable application of the present invention is an electrical lights decorating apparatus having two elongated electrical wires and a multiplicity of small lamps or sockets having the special connector members wired together to the two elongated wires.

Abstract: A glass lamp base may be formed by thinning the glass base in the area behind the point where the side lead is welded to the exterior surface of the screw. Thinning the glass behind the weld area helps assure that the remaining glass is firmly positioned to the back of the screw in the area of the weld, and has not slumped away from the screw. Assuring the glass backing is present, increases the likelihood of a successful weld, and functional lamp.

Abstract: A lamp base having a floating rivet pin is described. Due to mechanical stress, sealed beam reflector leads may need mechanical strengthening; however, heat stress may be transmitted through the strengthening means. A rivet pin may be coupled in the lamp base having one face abutting the base, a shaft portion closely, but slideably positioned in a passage and a second face offset from the base. During thermal expansion of the lead, the second pin face may approach abutment with the base without stressing the seal structures.

Second conductor connected to the other pin establishes an electrical connection between the usual eyelet of the base and the other pin when the base is threaded into said bore.

Abstract: An electric lamp including an insulative (e.g., plastic) base, an envelope located within the base and having a filament therein and a pair of conductors (e.g., nickel-iron alloy wires) projecting externally from the envelope, passing through the base and extending therefrom. Each conductor includes means (e.g., knurls) formed therein for removing undesirable surface material (e.g., oxide) from a respective contact located within a socket in which the lamp is positioned. Such removal, achieved during lamp insertion and eventual withdrawal, thus assures a sound electrical connection between the "cleaned" contact and a second lamp designed to replace the original. These features are particularly advantageous in the automotive field, especially that portion of the field involving taillight and similar assemblies.

The current conductors (7) are secured via a metal strip (8) to a current supply wire (14). Thus, deformations of the external current conductors (7) are avoided, which lead to mechanical stresses in the pinched seal (2) and to rupture thereof.

Abstract: An improved electric lamp including an electrically insulating (e.g., plastic) base which is securedly positioned on the lamp's sealed end portion without the need for adhesives or the like. The base functions to securedly retain the lamp's lead-in wires (a total of four in a dual filament lamp) in a preestablished alignment externally of the lamp's sealed end (from which the wires project) to thereby assure positive electrical connection thereto when the lamp and base are inserted within a corresponding electrical socket. This wire retention is possible by embedding each conductor within designated channels in the base and subsequent deformation of the base's material to substantially cover the embedded wire. In addition, a locking arrangement between the lamp envelope's press sealed end and the base is provided to assist in retaining the sealed end within an opening within the base. The invention is ideally suited for use in a tail light assembly for an automobile.
