Patent ID: 7250694

Claim:
A power-saving control module adapted to be coupled between an alternating current (AC) power source and a direct current (DC) power supply and adapted to be controlled by a remote control receiver, the DC power supply being capable of generating a DC power output upon receipt of an AC power input from the AC power source, the remote control receiver being capable of generating an enable signal upon receipt of a power-on signal, and generating a disable signal upon receipt of a power-off signal, said power-saving control module comprising: a switch component adapted to be coupled electrically between the AC power source and the DC power supply, and operable so as to make or break electrical connection between the AC power source and the DC power supply; a first diode adapted to be coupled electrically to the DC power supply and the remote control receiver, and providing a path for supply of the DC power output to the remote control receiver when connection between the DC power supply and the AC power source is made; a rechargeable power source adapted to be coupled electrically to the DC power supply and the remote control receiver, said rechargeable power source being recharged through the DC power output from the DC power supply when connection between the DC power supply and the AC power source is made, said rechargeable power source providing DC power to the remote control receiver when connection between the DC power supply and the AC power source is broken; and a driver coupled electrically to said switch component and adapted to be coupled electrically to the remote control receiver, said driver being responsive to the enable signal from the remote control receiver for causing said switch component to make electrical connection between the AC power source and the DC power supply, and to the disable signal from the remote control receiver for causing said switch component to break the electrical connection between the AC power source and the DC power supply.
