How much voltage for led

Nettet1. sep. 2024 · We already know that a LED requires a particular forward voltage (FV) to get lit. For example a red LED will need a FV of 1.2 V, a green Led will require 1.6 V and for a yellow LED it is around 2 V. The modern LEDs are all specified with approximately 3.3V forward voltage irrespective of their colors. NettetToday LEDs are made from a variety of materials and can emit a range of colors. Voltages vary from about 1.6 V for red LEDs to about 4.4 V for ultraviolet ones. …

Nettet16. mai 2016 · All LEDs (and all diodes, for that matter) have a basic "junction voltage" which varies around 1.8 to 2.5 volts (or so). The limiting resistor is designed to limit the current through the diode to it's safe operating level. So, yes, they should work unless they are large LEDs designed for high current and high brightness. Vamprie Member 55 Nettet6. mai 2024 · It’s important to remember that most individual LEDs are actually 3V DC devices, even though 12V or 24V DC is the most popular power supply voltages. Can a 220V LED light fixture run on 110V? The 220V bulbs can run on the same circuit as the 120V ones.
