Abstract: The present application relates to an adapter. The adapter includes a base and an adapter head inserted and fixed on the base. The base includes two base copper terminals mounted thereon and two connector wire holes defined therein, the connector wire hole is configured for inserting a connecting wire to contact with the base copper terminal, an assembling portion protruding out from a bottom end of the base is defined. The adapter head includes two adapter head copper terminals mounted thereon and two plug wire holes defined therein. The two adapter head copper terminals are in contact with the two base copper terminals, respectively. The plug wire hole is configured for inserting a plug wire to contact with the base copper terminal. An assembling hole is formed in a top end of the adapter head.

Abstract: A lamp system used in a light string system comprises a light assembly and a socket assembly. The light assembly comprises a light source, a base in communication with the light source, and a bypass activating system. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The bypass mechanism is in the first position when the light assembly is not seated in the socket assembly. When the bypass mechanism in the first position, current flows across the bypass mechanism. When the light assembly is inserted into the socket assembly, the bypass activating system of the light assembly moves the bypass mechanism into the second position, and current flows through the light source instead of the bypass mechanism.

The system includes: an input terminal connected to a rectifying circuit; the rectifying circuit being connected between the input terminal and a voltage-reducing and current-limiting circuit; the voltage-reducing and current-limiting circuit being connected between the rectifying circuit and the input terminal; and an output terminal being connected to the device for rectifying current, reducing voltage and limiting current.

Abstract: The light emitting diode (LED) light string system includes a plurality of lamp systems. Each lamp system includes a single LED, a base, and a globe to cover the LED. The LED light string system appears similar to the conventional incandescent light string system, but instead illuminates via LEDs. Each LED is covered by the globe similar to those available in incandescent systems, which provides refraction of the illuminated LED to produce an LED light string that has the look of a conventional incandescent light string.
