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.

Claim (Index 6):
The protection circuit of  claim 5 , wherein\n the charging/discharging regulator circuit includes: a first impedance element electrically connected between a connection node, where the control terminal and the capacitive element are connected together, and an output terminal of the control unit; and a series circuit of a diode and a second impedance element, the diode and the second impedance element being electrically connected in series between both terminals of the first impedance element, the diode is connected in such a direction that a charging current is allowed to flow toward the capacitive element via the diode itself and the second impedance element, the charging circuit includes a parallel circuit in which the first impedance element and the series circuit of the diode and the second impedance element are connected together in parallel, and the discharging circuit includes the first impedance element.
