LED 3mm green has been a staple in the lighting industry for decades. This compact, energy-efficient, and vibrant green light source has found its way into countless applications, from indicator lights to decorative lighting. In this article, we will delve into the world of LED 3mm green, exploring its history, technology, applications, and the future of this popular lighting solution.

History of LED 3mm Green

LED 3mm green has a rich history that dates back to the early days of LED technology. In the 1960s, Nick Holonyak Jr., a physicist at General Electric, developed the first practical LED. Initially, these LEDs were available in red, yellow, and green, with green being the most challenging color to produce. Over the years, advancements in semiconductor technology have made green LEDs more efficient and cost-effective, leading to their widespread adoption in various industries.

Technology Behind LED 3mm Green

LED 3mm green is a type of light-emitting diode that emits green light when an electric current is applied. The core of the LED is a semiconductor material, typically gallium nitride (GaN), which is doped with indium (In) and gallium (Ga) to create a p-n junction. When an electric current passes through this junction, electrons recombine with electron holes, releasing energy in the form of light. The specific color of the light emitted depends on the composition of the semiconductor material. LED 3mm green diodes are designed to emit light at a wavelength of approximately 525 nanometers (nm), which corresponds to the green part of the visible spectrum. The size of the LED, measured from the center of the semiconductor material to the center of the lens, is 3mm. This compact size makes them ideal for various applications where space is limited.
