Introduction to LED Diodes

LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it. Compared to traditional lighting sources like incandescent bulbs and fluorescent tubes, LED technology offers several advantages, including lower energy consumption, longer lifespan, and smaller size. The 5mm 3v LED diode is a popular choice due to its compact size and low voltage requirement.

Understanding 5mm 3v LED Diodes

The term "5mm 3v" refers to the physical size and voltage rating of the LED diode. The "5mm" indicates the diameter of the LED, which is 5 millimeters. The "3v" denotes the forward voltage required to make the LED emit light. This means that when a 3v voltage is applied to the LED, it will start to emit light.
