3mm IR LED, or Infrared Light Emitting Diode, is a compact and highly efficient component that has found wide applications in various industries. These tiny LEDs emit infrared light, which is invisible to the human eye but can be detected by specialized sensors. This article delves into the details of 3mm IR LED technology, its applications, advantages, and the market trends surrounding this innovative component.

Introduction to 3mm IR LED Technology

3mm IR LEDs are a type of semiconductor device that emits infrared light when an electric current is applied. The "3mm" refers to the diameter of the LED, making them extremely small in size. These LEDs are typically made of gallium arsenide (GaAs), gallium nitride (GaN), or other semiconductor materials that are capable of emitting infrared light efficiently.

When an electric current passes through the semiconductor material, it creates electron-hole pairs, which recombine and release energy in the form of photons. In the case of IR LEDs, these photons are in the infrared spectrum, which is not visible to the human eye. The wavelength of the emitted light can vary depending on the material and design of the LED, but it is typically in the range of 780 to 1000 nanometers (nm) for 3mm IR LEDs.
