Abstract

Abstract An adapter assembly for coupling a standard fluorescent lamp to an incandescent lamp fixture socket, comprising a base member having a lower threaded portion for disposal in the fixture socket, a ballast transformer electrically coupled to the threaded base, and a plurality of electrical contacts disposed in the base member and electrically coupled to the transformer for electrically coupling the electrodes of the fluorescent lamp to the ballast transformer. One end of the fluorescent lamp is disposed in a pair of the electrical contacts in the base member, while the other end of the tube is electrically coupled to the ballast transformer by a cap slidably disposed over the end of the lamp which includes electrical contacts coupled by elongated wires in an elongated tube disposed adjacent the lamp to another pair of contacts in the base member. The adapter assembly permits the insertion of a standard fluorescent lamp in an incandescent lamp socket fixture without modification.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 202 words
A fluorescent lamp adapter assembly, for coupling a fluorescent lamp to an incandescent lamp fixture socket, comprising: a base member, having a threaded lower portion for disposal in the fixture socket, and having a plurality of external electrical contact members disposed thereon electrically insulated from each other; a ballast transformer, disposed in said base member, and electrically coupled to said contact members; a plurality of electrical contacts, disposed in recesses in said base member for coupling the electrodes of the fluorescent lamp to said transformer, said contacts being arranged for receiving contact pins disposed on the ends of the fluorescent lamp; a cap, slidably disposed over one end of the fluorescent lamp, and including electrical contacts disposed therein coupled to said contacts in said base member, for receiving the contact pins of the fluorescent lamp, and thereby coupling one end of said lamp to said ballast transformer; and an elongated electrically nonconductive, generally L-shaped tube, coupled to said cap, and a plurality of electrical wires, disposed within said tube and coupled to said contacts in said cap, said wires extending from one end of said tube so as to form electrical contact pins receivable in said electrical contacts in said base member.
Claim 2
Dependent Claim 202 words
A fluorescent lamp adapter assembly, for coupling a fluorescent lamp to an incandescent lamp fixture socket, comprising: a base member, having a threaded lower portion for disposal in the fixture socket, and having a plurality of external electrical contact members disposed thereon electrically insulated from each other; a ballast transformer, disposed in said base member, and electrically coupled to said contact members; a plurality of electrical contacts, disposed in recesses in said base member for coupling the electrodes of the fluorescent lamp to said transformer, said contacts being arranged for receiving contact pins disposed on the ends of the fluorescent lamp; a cap, slidably disposed over one end of the fluorescent lamp, and including electrical contacts disposed therein coupled to said contacts in said base member, for receiving the contact pins of the fluorescent lamp, and thereby coupling one end of said lamp to said ballast transformer; and an elongated electrically nonconductive, generally L-shaped tube, coupled to said cap, and a plurality of electrical wires, disposed within said tube and coupled to said contacts in said cap, said wires extending from one end of said tube so as to form electrical contact pins receivable in said electrical contacts in said base member.
