Title: Electrical light socket
Inventor: GIBBONEY JAMES W JR
IPC: H02M7/06
Filed: 1999-05-10
Granted: 2005-11-01
Abstract: A light socket is disclosed that has a built-in integrated circuit for rectifying the alternating current received from an electrical outlet and limiting the direct current produced. The light socket is specifically suited for low-current, low-voltage applications such as supplying DC to a string of ornamental lights.
