  • Patent number: 10708989
    Abstract: A control unit controls a bidirectional switch so as to turn the switch from ON to OFF when an amount of time, varying according to a lighting level, passes since a starting point of a half cycle of an AC voltage. When a voltage between both terminals of a capacitive element, connected to a control terminal of the bidirectional switch, becomes equal to or greater than a threshold voltage, the bidirectional switch turns from OFF to ON A first charging/discharging regulator circuit and a second charging/discharging regulator circuit each make a rate of fall of the voltage between both of the terminals of the capacitive element when the bidirectional switch turns from ON to OFF lower than a rate of rise of the voltage between both of the terminals of the capacitive element when the bidirectional switch turns from OFF to ON.
