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.

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.

Brian

Dimming LEDs in a FC circuit can be very linear right down to almost
out. On an AC circuit running at 60HZ the resolution gets pretty
rough. The switching rate is only 60 times per second so the on/off
ratio is pretty limitted whether using rizing edge, falling edge or
zero crossing switching -

With DC the switching rate can be whatever the engineer wants, and
the mark space ratio (duty cycle) can also be manipulated quite
successfully

As for "Rev Limiters" in the subject I ASS U ME the original question
was aboput engine rev limiters and how the engine "hunts" on the
limiter. This is due to Fuel Cut being used to limit the speed and it
being an "all or nothing" process - fuel injection shuts off at a
programmed RPM and comes back on when the RPM drops to a lower
programmed RPM. It is theoretically possible to make a smooth cut-off
but it is programattically complex - and for what advantage???
The "choppy" rev limitter lets the driver know he has hit it - a soft
limit would tempt an agressive driver to stay "on the limit"
constantly (like a diesel truck on the governor)

A controlled current regulator.

ratios.


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.

However it is obvious that even the briefest of ons and the longest offs
tends to still be visible in most cases,


That’s mad, leds have very little inertia.

and not terribly accurate if many leds are used as the load, there being a
spread of linearity in any given number.


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.

Doesnt necessarily cost anything more at all with leds. Same price as
voltage regulators.

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.

Peeler's skin is only attached to the body along the center ridge of the

When Peeler is captured and held, e.g., by the tail, he secretes the

Engines that run stochiometric have to be all or nothing. Diesel are

petrol but I don't know from experience because mine just shifts up and

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.


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.


Engines that run stochiometric have to be all or nothing. Diesel are
smoothly limited. It ought to be possible to smooth limit stratified
petrol but I don't know from experience because mine just shifts up and
keeps going.


My car is an automatic so that is what it does. I never tried putting it
in first or second to see what it does when it hits the limiter.

Two of my bikes have carburetors so manipulating injectors isn't an
option. I haven't hit the limiter on the other bike and just shift at
10000.

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

The driver would still feel the lack of power.


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


And you ****ed up uk.d-i-y in the newsgroup list, you have uk.diy



Had a rev limiter on my RS1600 with electronic ignition in 1975, it worked
well at 6700 rpm.

Rheological investigations showed that Peeler's slime viscosity
increases in elongational flow which favours gill clogging of suction
feeding fish, while its viscosity decreases in shear which facilitates
scraping off the slime by the travelling-knot.

Peeler's slime has been proven to impair the function of a predator
fish's gills. In this case, Peeler's mucus would clog the predator's
gills, disabling their ability to respire.
