Editors’ Note: This segment is adapted from Chapter 3 of Power Supplies for LED Driving by Steve Winder. We have seen in Chapter 2 that an LED behaves like a constant voltage load with low equivalent ...

However, you can't just hook any LED in parallel. Each will have it's own voltage drop. If one is enough lower than the others then all the current will go through that one and none to the others.

Solid state lighting solutions are increasing in popularity across a broad variety of illumination, indication, signage and backlighting applications, replacing traditional incandescent and ...

That was very helpful in understand how LEDs work. What I'm trying to do is make a lamp that will have the maximum amount of white LEDs I can run off of 126V AC directly. I understand I need to limit ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
