Patent ID: 8242640

Claim:
A power system with light-controlled function, comprising: a remote control device, comprising: a light sensor module, which outputs a first electrical signal indicative of an ambient illumination; a first microprocessor, which is coupled to the light sensor module, determines whether the first electrical signal exceeds a first threshold, and outputs a first control signal according to whether the first electrical signal exceeds the first threshold; a wireless transmitter, which is coupled to the first microprocessor for transmitting the first control signal; and at least one power socket device, comprising: at least one controlled socket; a wireless receiver, which receives the first control signal; and a second microprocessor, which is coupled to the wireless receiver and the at least one controlled socket, for controlling a state of power supply in the at least one controlled socket according to the first control signal by causing the controlled socket not to be powered when the first electrical signal fails to exceed the first threshold.
