Title:
マイクロプロセッサで制御された電源を有する調光器
Document Type and Number:
Japanese Patent JP4729617
Kind Code:
B2
Abstract:
A load control device includes a power supply that supplies power to a microprocessor and a load circuit (e.g., a light-emitting diode and/or a communication circuit). The power supply comprises an energy storage element, e.g., a capacitor, for producing a DC voltage for powering the microprocessor and the load circuit. The microprocessor is operable to monitor the power supply and to control the amount of power delivered to an electrical load connected to the load control device in response to the monitoring of the power supply. In addition, the microprocessor is operable to cause the load circuit to draw less current in response to determining that the energy storage capacitor does not have enough time to charge during each half-cycle of the AC voltage.
