    I'm searching for a simple circuit of automatic lighting that includes triac. Can anyone show me the circuit?

    From where the light will be activated automatically?

    My circuit should be activated by a battery(6v), and it includes relay too.

    Unless the lighting includes a dimming feature, the relay should provide adequate control for on/off. Triacs don't work with DC, either for control or for on/off operation.

    We need more information about the circuit you have in mind.

    Yes but what will cause the relay to turn on?

    I mean on what condition the light will light?

    When the weather is dark, the triac causes to turn on the light. What should I do to use triac instead of relay and there is a battery(6v) to provide current of the light(220v). Also, turn off it when the weather is light.

    Alberto,
    Thanks for your suggestion, but you're missing the point. My aim is to learn how to design a simple circuit.

    Is the lamp a 120VAC or 240VAC one?

    I think yes. Isn't the streets or homes' lamps 230VAC?

    Hello,

    Depends where you live.
    Here in Holland (and most countries in europe) it is 230 Volts.
    In the USA it is 120 Volts.

    Greetings,
    Bertus
