Patent ID: 7714464

Claim:
A load control module, for an electrical equipment, wherein the electrical equipment is controlled by an operation of a switch, the load control module comprising: an energy storage unit, for converting a supply voltage and outputting a reserved voltage when the switch is turned on, and continuously outputting the reserved voltage for a predetermined time when the switch is turned off; a signal transforming unit, coupled to the energy storage unit, and driven by the reserved voltage, configured to transform the supply voltage output from the switch into a counting signal; a first control unit, coupled to the energy storage unit and the signal transforming unit, and driven by the reserved voltage, configured to filter and rectify the counting signal to output a rectified signal, wherein when a level of the rectified signal is switched to a second level, the first control unit latches the level of a clamping signal to the second level, and until the first control unit is reactivated, the first control unit then outputs the clamping signal having a first level; and a second control unit, coupled to the energy unit, the signal transforming unit, the first control unit and the electrical equipment, and driven by the reserved voltage, configured to output a control voltage to control characteristic parameters of the electrical equipment, wherein when the second control unit receives the clamping signal having the first level, the second control unit counts continuously in response to the counting signal, so as to adjust the level of the control voltage according to a counting result, and when the second control unit counts up to a predetermined value or receives the clamping signal having the second level, the second control unit stops counting, the level of the control voltage is switched to one of a plurality of predetermined levels according to an inverted signal of the rectified signal.
