History of LED Diode 3mm

The history of LED technology dates back to the early 20th century when the first LED was invented by Oleg Vladimirovich Losev in 1927. However, it wasn't until the 1960s that LED diodes started gaining attention, primarily due to their ability to emit light in a specific color. The 3mm LED diode was introduced in the 1970s, and since then, it has become a popular choice for various applications due to its compact size and energy efficiency.

Technology of LED Diode 3mm

The 3mm LED diode is a semiconductor device that emits light when an electric current passes through it. The diode consists of a P-type semiconductor and an N-type semiconductor, creating a PN junction. When an electric current is applied, electrons from the N-type semiconductor combine with holes from the P-type semiconductor, releasing energy in the form of light. The 3mm LED diode has a diameter of 3mm and is typically mounted on a small, flat printed circuit board (PCB). The LED emits light in a specific color, which is determined by the material used in the PN junction. Different materials can produce different colors, such as red, green, blue, and yellow.
