How 3mm Infrared LEDs Work

To understand the functionality of 3mm infrared LEDs, it's essential to know their basic structure. These LEDs consist of a semiconductor material, typically gallium arsenide (GaAs), that emits light when an electric current passes through it. The semiconductor material is sandwiched between two metal contacts, known as electrodes, which facilitate the flow of current. When the current passes through the semiconductor, it excites the electrons, causing them to recombine with electron holes, releasing energy in the form of photons. These photons are in the infrared spectrum, making them invisible to the naked eye. The 3mm size of the LED refers to its diameter, which is approximately 3 millimeters. Despite their small size, 3mm infrared LEDs offer remarkable performance and efficiency. They emit a wide range of infrared wavelengths, from 780 nm to 1000 nm, depending on the specific material and design. This versatility allows them to be used in various applications, from remote controls to medical devices.
