On cars? Yes. Cutting the engine abruptly when you hit the red line
wouldn't be good so they simulate ignition breakup to give you a hint.

Never saw the original post. There is a holding current in a triac, and once
the current drops below this a kind of Hysteresis occurs so you need to turn
it up to get it conducting again.

leds don’t dim using triacs but still cant be dimmed right down close
to zero for use as a nightlight with the philips hues particularly.

Just what makes the unwashed Scottish wanker so irresistible to some of you
disgusting senile assholes? Is it the fact that he admitted that he never
wears any underwear? Or is it the fact that he rarely washes? Or both? YUCK!

Peeler has a cartilaginous skull (although the part surrounding the
brain is composed primarily of a fibrous sheath) and tooth-like
structures composed of keratin.

Peeler has no true fins and has six or eight barbels around the mouth
and a single nostril.

Instead of vertically articulating jaws like Gnathostomata (vertebrates
with jaws), Peeler has a pair of horizontally moving structures with
tooth-like projections for pulling off food.

You must be the dumbest gay shitty byker in the UK's streets! LOL

OK what do they use then, All I remember from my brief experience trying to
dim leds was that the most successful way of doing that was by duty cycle,
ie on to off times with them driven by some kind of oscillator with variable
mark space ratios. However it is obvious that even the briefest of ons and
the longest offs tends to still be visible in most cases, and not terribly
accurate if many leds are used as the load, there being a spread of
linearity in any given number.

A controlled current regulator.

It is much better to control the current thru the leds.

And it makes no sense to use a triac when varying
the mark/space ratio with leds anyway.

That’s mad, leds have very little inertia.

That would be a mad approach too.

PWM is the cheapest way as it needs no other component.

For a small improvement in efficiency then a constant current source
would be best but obviously costs more.

Doesn’t necessarily cost anything more at all with leds. Same price as
voltage regulators.

Yes, I made a PWM dimmer circuit (for fun) based on circuits I found on
the Internet and it works well, and dims to nothingness. (12VDC working
a white LED strip.)

do it at high enough frequency and there is no visible flicker, and you
can feed the LEDS via a small ferrite inductor with a parallel capacitor
and reduce HF flicker too.

But at that point you've already gone over the peak of the power curve. I'd just make it drop the curve more quickly so it can never go too fast. The driver would still feel the lack of power.

Not possible to do that and still get the best performance.

Makes more sense to have a rev limiter and much easier to do too.
