Abstract:
In a light-dimming device according to an example of the present invention, a controller is configured to be supplied with control electric power from an electricity accumulator to operate and to retain a bidirectional switch in an on state for an on time having a length according to a dimming level in every half period of an AC voltage of an AC power supply in a lighting mode. A charger including a first charger and a second charger causes a current to flow from a pair of input terminals and to the electricity accumulator. An impedance of the second charger which is a charger in a case of causing a current to flow to the electricity accumulator in the lighting mode is lower than an impedance of the first charger which is a charger in a case of causing a current to flow to the electricity accumulator in a non-lighting mode.

Claim (Index 1):
A light-dimming device, comprising:\n a pair of input terminals electrically connected between an illumination load and an AC power supply; a bidirectional switch configured to switch between non-conduction and conduction of a bidirectional current between the pair of input terminals; an inputter configured to receive a signal denoting a dimming level specifying a magnitude of a light output of the illumination load; an electricity accumulator configured to accumulate an electric charge to generate control electric power; a controller configured to be supplied with the control electric power from the electricity accumulator to operate and to retain the bidirectional switch in an on state for an on time having a length according to the dimming level in every half period of an AC voltage of the AC power supply in a lighting mode in which the illumination load is on; and a charger configured to cause a current to flow therethrough from the pair of input terminals to the electricity accumulator, wherein an impedance of the charger in a case of causing a current to flow to the electricity accumulator in the lighting mode is lower than an impedance of the charger in a case of causing a current to flow to the electricity accumulator in a non-lighting mode in which the illumination load is off.
