Why Do You Need Resistors With Leds at Alfred Humphries blog

Why Do You Need Resistors With Leds. We want to balance out having enough current to cause the level of brightness desired without having so much that the led material fails. If you have a high current led or a very large voltage difference, then the resistor has to waste a lot of power. As usual, alex at tinkerlog does an excellent job of clearly describing some electronics arcana, in this case, exactly why one needs to use current limiting resistors on leds (and when. What is needed is a means to limit the current that flows through the led. Leds have current ratings which indicate the. If you are building an led system. The main reason leds need resistors is to protect the led from excessive current which can permanently damage the led. You need to find a datasheet for your leds or measure their forward voltage so that you can work out what resistance you need to avoid burning them out. It is necessary to connect a resistor with an led in most circuits to ensure proper operation and longevity of the led. Resistors offer an expedient means for limiting the current through an led to safe levels, but they.
