Patent ID: 7965025

Claim:
A decorative light comprising a socket, a bulb base, a bulb and two terminals, wherein the bulb is disposed on the bulb base, with two electrodes of the bulb passing through the bulb base to form two contacts at the bottom of the bulb base; the socket is shaped like a barrel, the bulb base is inserted into a top end of the socket, and the two terminals are inserted into a bottom end of the socket, with the two contacts contacting against the two terminals, the decorative light being characterized in that the socket is further provided with a retainer therein, which has an opening laterally extending therethrough, and an elastic conductive ring with a thickness smaller than a width of the opening is disposed within the opening; when the elastic ring is in a natural state, the elastic ring extends outside the retainer through the opening at two sides of the retainer; the bulb base is further provided with an inserting partition at the bottom thereof; the elastic conductive ring has two states: one is a separating state where the bulb base is inserted into the socket, in which state the inserting partition of the bulb base separates one side of the elastic ring from the corresponding terminals thereby allowing electrical contact through the bulb from the terminals; the other is a conducting state of the two terminals when the bulb base is removed from the socket, in which state both sides of the elastic conductive ring contact against the two terminals respectively to provide electrical contact between them.
