Triac dimmer with LED lightbulb

[eem2am]

Supposing I have a mains LED lightbulb which is not meant to be dimmable.
Now suppose I accidentally connect a triac dimmer to it.

Will the constant "smashing" on and off of the mains by the triac switching repeatedly over-excite the LED bulb's EMI filter such that it fails prematurely?

There will be no "smashing" off.

The EMI filter is unlikely to suffer.

If there is an input capacitor then it may be subject to higher than normal ripple currents.

Below is the new way of dimming mains LED bulbs with a wall dimmer.

No more triacs for LEDs.

When you push the button on the wall dimmer, it "cuts out" a mains half cycle at the zero crossings, and the bulb circuit interprets this as "dimming required" and then it either dims the bulb down by a bit, or dims it up by a bit.

Triac dimmers must be consigned to the museums.....there sudden on-switching just resonates with the emi filter of the led bulb......the emi filter of the led bulb needs damping due to the triac dimmer, and bleeder circuits are needed.....also, not one single dimmable led bulb on earth is properly dimmable with every triac dimmer on the market.

Why do you bother asking questions before "answering them" yourself?
