LED 3mm green is a popular type of LED that emits green light. With its small size and high brightness, it has been widely used in various applications, such as indicator lights, automotive lighting, and consumer electronics. This article will provide an in-depth introduction to the LED 3mm green industry, covering its history, technology, applications, and market trends.

History of LED 3mm Green

LED 3mm green has a long history, dating back to the early days of LED technology. In the 1960s, Nick Holonyak, an engineer at General Electric, invented the first practical LED, which emitted red light. Over the years, LED technology has evolved, and green LEDs were developed in the 1970s. The 3mm green LED was introduced in the early 1980s, and it quickly gained popularity due to its compact size and high brightness.

Technology of LED 3mm Green

The 3mm green LED is a type of light-emitting diode that emits green light. It consists of a semiconductor material, typically gallium nitride (GaN), which is doped with indium (In) to create a p-n junction. When an electric current is applied to the p-n junction, electrons and holes recombine, releasing energy in the form of photons. The wavelength of the emitted light depends on the composition of the semiconductor material. The 3mm green LED has a diameter of 3mm and a height of about 1mm. It is mounted on a small metal or plastic substrate, which serves as a heat sink and an electrical contact. The LED emits light in a directional manner, which is controlled by the design of the LED package.
