A control circuit for regulating current supplied from a power source to at least one load. The control circuit has a current mirror circuit electrically coupled between the power source and the at least one load, and being capable of regulating current supplied from the power source to the at least one load at different levels; a real-time clock (RTC) circuit adapted for recording real time; and a micro control unit (MCU) electrically coupled between the RTC circuit and the current mirror circuit, and configured such that when the real time changes from a first time period to a second time period, the MCU generates control signals to trigger the current mirror circuit to regulate current supplied from the power source to the at least one load from a first level corresponding to the first time period to a second level corresponding to the second time period. |
