  • Patent number: 6863573
    Abstract: The MR16 lamp adapter is an apparatus which allows for one to convert their 120 volt AC lighting device to a lower voltage AC light device by attachment of an Edison lamp base on one end of the apparatus within the Edison socket of the AC light device, the apparatus having an encased voltage converter within a non-conductive extension, reducing the voltage from 120 volt AC to the lower AC voltage. The apparatus has a lower voltage AC light socket with a bulb on the opposing end of the apparatus to accept a low voltage light bulb. This apparatus is most preferred for converting 120 volt AC recessed light canisters without incurring costly and difficult retrofitting of low voltage light device in the place of the existing 120 volt AC recessed light canisters, which may be placed in locations where access is restricted, confined or otherwise inaccessible.

  • Patent number: 5320548
    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.
