Patent number: 10616975Abstract: A bidirectional switch is switched so as to conduct and interrupt a bidirectional current between a pair of input terminals. A power supply is electrically connected between the pair of input terminals and produces control power by electric power from an AC power supply. A controller receives the control power from the power supply to be activated. The controller causes the bidirectional switch to be in an off-state from a start point of a half cycle of AC voltage to a first time point when a first time period elapses. The controller causes the bidirectional switch to be in an on-state from the first time point to a second time point when a second time period according to the dimming level elapses. The controller causes the bidirectional switch to be in an off-state from the second time point to an end point of the half cycle.Type: GrantFiled: November 18, 2018Date of Patent: April 7, 2020Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kiyosi Gotou, Tomohiro Miyake, Takeo Suzuki
