<p>The device has a light source attached to a Q-bar output of a D-Flip-Flop (14) at a Q-output of the D-Flip-Flop. An anti-interference network (10) is provided with three ports (E1, E2, E3), where one of the ports is coupled with a connection (A2) of a pushbutton (T), and the other port is coupled with a clock input of the flip-flop. The network has a connection between the former and third ports, where the connection of the network represents a high impedance resistance for a direct current signal and a low impedance resistance for an alternating current interference signal. An independent claim is also included for a method for operating a lighting device with a light source and a button device.</p> |
