ABSTRACT:
A lamp adaptor for adapting a lamp to an incandescent lamp socket includes a body and a contact assembly. The body includes an electrical circuit for converting incandescent lamp electrical supply levels to electrical supply levels of the lamp. The contact assembly is connected with the electrical circuit and configured to threadably connect with an incandescent lamp socket by rotating the contact assembly in a forward radial direction. The contact assembly includes a conducting screw shell that is configured to threadably engage in an incandescent lamp socket, a support defined by the body for the screw shell, and a ratchet coupling the screw shell with the support. The rachet provides a grip between the screw shell and the support when the contact assembly is rotated in the forward radial direction. The ratchet provides substantially free rotation between the screw shell and the support when the contact assembly is rotated in a rearward radial direction in order to prevent unauthorized removal of the lamp adaptor from an incandescent lamp socket. A removal tool is provided to engage the contact assembly in a manner that provides a grip between the screw shell and the support in order to allow removal of the lamp adaptor from an incandescent lamp socket.
