I have some questions about Overdriving, I am still not feeling to confident about building circuits and I feeling that everything I'm doing is just lucky guessing. I've attached a gif of a possible LED lighting schematic.
I used an LED calculator to help generate this. I entered the following specifications about the LEDs.
Source Voltage: 34v
Forward Voltage: 3.4 Typical
Forward Current: 100ma
Total Number of LEDS: 50
When these led calculators build these diagrams aren't they technically overdriving them? I really do not understand how you overdrive an LED.
From how I see it, the first LEDs have 34 Volts running through them. The Next set have a 3.4 voltage drop? But since the first set in the series are 34v passing through aren't they over driven?
If they are not overdriven, what would I need to change in my diagram to make my LEDs overdriven? I really don't get it, and I would like to at least know how to avoid over driving LEDS. My assumption about electrical components to this point has been that you can run as many amps through something and they only draw as many amps as are needed, but overdriving seems to basically through this Idea that I have out of the window.
In my diagram since I am using an LM317 (1 Amp Current Regulator) can avoid the use of resistors?
On the LM317 or LM317 what is the Adjustment line for?
On other ICs what is a vRef for?
