LED 5mm green is a popular and widely used type of LED lighting. With its compact size, low power consumption, and vibrant green color, it has found applications in various fields, from indicator lights to decorative lighting. In this article, we will delve into the industry of LED 5mm green, exploring its history, technology, applications, and future prospects.

History of LED 5mm Green

LEDs, or Light Emitting Diodes, were first discovered in the 1920s by an American physicist named Henry Joseph Round. However, it wasn't until the 1960s that LEDs started to gain attention as a potential lighting source. In the early 1970s, red, yellow, and green LEDs were developed, and the 5mm LED was introduced in the 1980s. Since then, the LED industry has grown exponentially, with the 5mm green LED becoming a staple in the market.

Technology of LED 5mm Green

The 5mm green LED is a semiconductor device that emits light when an electric current passes through it. The device consists of a semiconductor material, typically gallium nitride (GaN), which emits light when excited by an electric current. The green color is produced by a phosphor coating on the GaN chip, which converts the blue light emitted by the LED into green light. The 5mm green LED is characterized by its small size, which allows for easy integration into various applications. It typically has a diameter of 5mm and a height of 3mm, making it suitable for use in indicator lights, displays, and decorative lighting. The LED emits light in the visible spectrum, with a peak wavelength of around 520nm.
