Minimum Current Required For Led To Glow at Nathan Dwyer blog

Minimum Current Required For Led To Glow. You'll be putting 5v divided by 3, or 1.7v on each led. For a standard led of 5mm diameter, figure 1 shows the forward voltage (v f) vs. P = ie where p = the power. Most common led’s require a forward operating voltage of between approximately 1.2 to 3.6 volts with a forward current rating of about 10 to 30 ma, with 12 to 20 ma being the most common. So basically is there a minimum current for leds to be lit? So, to maximize battery life, you should use the minimum current that will produce a light. I have a blue led that is very well lit with less than 0.4ma and it seemed strange to me. But, you're right in that. But if adding limiting current resistor on this group led light, it will be lower than the minimum led driving voltage, and it. At 20ma, you get 10mw/sr radiant intensity. Led currents are often quoted at, or. If you look at the current curve (i pasted it below from the datasheet), at 1.7v you'll get about 2 ma of current. Answer is so involved that several pages on the web are required to explain how to do it.
