  • Patent number: 4936789
    Abstract: An adaptor (12) includes a threaded portion (14) intended to be screwed into a conventional lamp socket (18) to replace a standard incandescent light bulb. The adaptor includes spring clips (38) that are operative to prevent removal of terminal pins (36) on the base of a fluorescent lamp (30). A table lamp (20) in which the adapter is installed is connected through a male polarized electrical plug (62) to a remote power supply (68). The power supply is plugged into a conventional AC wall outlet (74). A tamper-proof fastener (78) attaches the power supply to the outlet, preventing it from being removed by a user who does not have access to a special driver required to turn the fastener. Spring clips within the power supply prevent removal of the male plug, so that the table lamp cannot be stolen without cutting the power cord.
