Buy IR LED: An In-Depth Industry Overview

Introduction to IR LED

The phrase "buy IR LED" refers to the purchase of Infrared Light Emitting Diodes (IR LEDs). These are semiconductor devices that emit infrared light when an electric current is applied to them. IR LEDs are widely used in various applications due to their compact size, low power consumption, and high efficiency. The market for IR LEDs has been growing steadily, driven by advancements in technology and increasing demand across various industries.

How IR LEDs Work

IR LEDs work on the principle of the PN junction. When an electric current passes through the PN junction, electrons recombine with holes, releasing energy in the form of photons. 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 used in the LED and its design.
