I just purchased an LED lamp. After opening it, I saw inside a circular
aluminum plate with LED lights on it. On one end of the power supply is
a 3-lead connector for L, N, and G wires. On the other end are two wires
going to the aluminum plate. Since aluminum is conductive and the wires
seem to go directly to the aluminum plate, why doesn't it get
short-circuited? Is there an invisible circuit on the aluminum plate?

It is probably not aluminum. The ones I have used are copper
tracks plated with solder. The plating looks like aluminum.
It is also a pain in the neck to solder aluminum.

One side may be aluminum as a heat sink. The other side may be a printed
circuit board.

I have no clue. How Its Made did an episode on LED tube lights. Said
the metal served as "heat sink".

Do these tubes directly replace florescent tubes, or do your
need to modify something such as the exciters?

I was sorting out the same thing. Likely related to 120 VAC .

Hay! They votes for Brexit, so be nice to them. Well,
for the next couple of weeks anyway, then you can go
back to giving them a bad time (they deserve it)!

Why do you care one way or the other what the Britts do with
regard to the EU? Seems to me it's their country and their
choice.

AKA starters, something that provides a few high-voltage pulses between
the pins to get the lamp going.

Ran out of American things to watch on NetFlix. The Korean
Dramas (Soaps) are so much better than the American shows
it is unbelievable. The brits have some good stuff too,
but they talk like they have food in their mouths, so
subtitles it is.

Got a job in Reno. Use to have family up here. I liked it
and I stayed. That was 30 years or so ago.

What made you come Nevada?

The PRC is in a huge gun referendum.

You can run AC through them. You have two parallel strands
in opposite polarity. One side is on while the other side is
off. And since the are only on half the time, you can
put more current through them to make up for them being
off half the time.

Works great, except the flicker can be something to behold.
You can tell if this is happening by positioning your hand in
front of one and waving it back and forth. If your hand looks
jittery as it goes back and forth, it is being pulsed.
