220v led bulb array delay Answered

I made a makeup mirror with 15 holes for lights, now iwouldlike to have a slight ON delay from one to the other. I was thinking maybe a capacitor after each bulb or just a relay? ( figured the relay kind of has a 0.1 second delay)

One more circuit.

This only works with 3W lamps !

3W at 220V DC is almost 13 ma DC.

Are we on the same page ?

Correction "almost 14 ma" actually13.6 ma DC.

If your leds run on AC you cannot use capacitors to delay.

You will have to use a ring counter IC and SSR relays to switch ac lamps..

thank you very much
just to be sure ? capacitors wont work even just for 0.1 second?

It is called a "chase light".. Capacitors only cause a phase shift on AC.

While it can be easily done using a combination of the three references.

In the end a microprocessor running opto triac isolators will be quicker to go.

Both need a wall wart power supply.

thnx a bunch but its to much work and$ unless there is a reay to run module in aliexpress .

i guess i will just wire them directly

thnx again very helpful

Just to see, a DC chase circuit, I had lined up.

This could be modified for a ramp up instead of a ring run.

But DC is required !
