Well with the greatest of respect why do you dispute my certain knowledge of how some kit is manufactured? and yes telling me I have it wrong is insulting me.
One piece of equipment I have repaired several times (nothing to do with the LED arrangement) contains several blue LEDs, call them backlights, wired in parallel on the 6.5V 3VA transformer winding with only a series 33Ω resistor... no diodes, no rectifiers, no anything else.
Thousands of indicator lamps I've fitted in control panels and spec'd as AC/DC & marked with +&- consist of a 8mm LED, a series resistor and a shunt resistor... no diodes, no rectifiers, no anything else. The values are dependant on the designed operating voltage, IIRC the shunt is 680Ω and the 20-30V version contains 2.5KΩ series.
Please start accepting the truth in what others state as fact.
As you are yet again trying to be pedantic, can you please explain to the assembly here how I am so wrong and why a diode is at risk of damage if its PIV is not exceeded?
