Abstract: The present invention relates primarily to a modular replaceable ballast as used in a table or floor lamp using a circular fluorescent lamp as the primary source of illumination. Circular fluorescent lamps have been in use for many years to provide superior operating and lighting efficiency. These lamps can provide many years of trouble free performance, obviating the need for frequent replacement that is needed by comparable wattage incandescent bulbs. The ballasts, on the other hand, have not enjoyed the same degree of success of having similar reduced failure rates. The present invention utilizes a plug-in replaceable electronic ballast which can easily be replaced by a novice person. Because this ballast is plugged into a compatible adapter receptacle, the need for dismantling or disassembling the fixture is thereby obviated. The plug-in electronic ballast has two centrally located pins that insert into the newly designed modular receptacle.

Abstract: To permit use of a compact fluorescent lamp having a base with projecting rminal pins (9) in an ordinary standard Edison lightbulb socket, an adapter has a lightbulb thread (2) and the housing body includes a reception well (5) to receive a locating plate or plug (6) from the lamp. To relieve stresses and strains on reception terminals (11) which are electrically connected to a printed circuit board (3) within the adapter body, the reception terminals, and preferably the connecting lugs thereof, are formed with openings which are engaged by matching projections formed on the housing body, and preferably by projections extending from the wall defining the well (5) which receives the locating plate or lug (6) of the lamp. This avoids bending, and hence damage to the printed circuit board upon insertion of the lamp pins (9) in the spring contact portions (11a) of the reception terminals since assembly stresses are accepted by the housing body and not by the printed circuit board.
