Abstract
A lock-in compact fluorescent lamp (CFL) adaptor that would be screwed into the socket of a conventional incandescent lamp assembly. It has an adaptor casing whose respective top wall, bottom wall and outer side walls form an electrical components chamber for a ballast, a printed circuit board, and electrical wiring. A CFL post member socket is formed in the top wall of the adaptor casing. An electrical contact base is connected to the bottom wall of the adaptor casing and it has a conventional externally threaded outer electrical contact surface that would be received into a conventional incandescent lamp socket. The adaptor has structure to prevent unauthorized removal of the compact fluorescent lamp from the adaptor. The adaptor casing also has a pair of vertically oriented slots for receiving and capturing the bottom legs of a harp used with a lamp assembly. One alternative embodiment of the adaptor has a removable electrical contact base. Another alternative embodiment has an adaptor designed to function with a compact fluorescent lamp having an inverted base structure.
