Patent ID: 8779680

Claim:
An AC power-line dimmer assembly that enables simultaneous operations of dimming and DC power supplying through a single pair of electrical wires; the dimmer assembly comprising: a pair of terminals for connecting the dimmer assembly to a power-line electrically in series with a power-line load; a dimmer switch; a power and dimmer control unit configured to control the power conveyed to a power-line load by opening and closing the dimmer switch; a DC-powered electronic circuit; a first power supply, further comprising: a first capacitor configured to store energy for powering the DC-powered electronic circuit; a first controllable current limiter configured to charge the first capacitor from the power-line by generating current pulses following at least part of the zero-crossings of the power-fine voltage, the current pulses having a pulse width exceeding a pre-determined value, to make said current pulses identifiable as power supply current pulses; wherein the current limiter is characterized in that It is set to a current limit that is not restricted by said power-line load impedance.
