History of LED 3mm Green

LEDs, or Light Emitting Diodes, have been around for several decades. The first practical LED was invented by Nick Holonyak Jr. in 1962 at General Electric. Initially, LEDs were limited to red and green colors, with the green LED being a significant breakthrough. Over the years, advancements in technology have led to the development of various colors, including the 3mm green LED. The 3mm green LED gained popularity in the 1980s and 1990s, primarily due to its use in indicator lights and displays. As the technology matured, the demand for 3mm green LEDs increased, and they became a staple in the lighting industry.

Technology Behind LED 3mm Green

The 3mm green LED is a semiconductor device that emits light when an electric current passes through it. The key components of a 3mm green LED include the following: 1. Semiconductor material: The core of the LED is made of a semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP). These materials have a direct bandgap, which allows them to emit light when excited by an electric current. 2. P-N junction: The semiconductor material is doped with impurities to create a P-N junction. When an electric current is applied, electrons and holes recombine at the junction, emitting photons in the process. 3. Encapsulation: The LED is encapsulated in a transparent or translucent material, such as epoxy or glass, to protect the internal components and enhance light output. The 3mm green LED operates at a voltage of approximately 2.0 to 3.5 volts and a current of 20 to 30 mA. Its compact size, typically measuring 3mm in diameter, makes it suitable for a wide range of applications.
