Title: An automatic energy-saving apparatus and a concent using sensor
Inventor: HWANGBO SEUNG
IPC: H01R13/70
Filed: 2000-10-05
Abstract: PURPOSE: An automatic power-saving device using a sensor is provided to build a sensing unit including the sensor and a controller in an outlet, and to selectively sense time zones when electrical energy supply is not necessary, to automatically intercept or supply an AC power, so as to reducing power consumption as well as preventing fire. CONSTITUTION: An AC/DC converter is composed of a rectifier, a DC/DC converter unit, and a smoother. The rectifier rectifies an AC power. The DC/DC converter unit converts a rectified signal into a DC power. The smoother smooths the converted DC power. A sensing unit has a photo transistor and a switch controller. The photo transistor is turned on by sensing a light over a regular time, and is turned off if the light is not sensed. The switch controller is intercepted if the photo transistor is turned on, and is coupled with the DC power when the photo transistor is turned off. A switch supplies energy of the AC power to an electrical product through a plug connector if the switch controller is intercepted. If the switch controller is turned on, the switch intercepts the energy supplied to the electrical product.
