What is an IR LED?

An Infrared Light Emitting Diode, or IR LED, is a type of semiconductor diode that emits infrared radiation when an electric current is applied. Unlike visible light, infrared radiation is not visible to the human eye, but it is widely used in various applications due to its unique properties. IR LEDs come in different wavelengths, ranging from near-infrared (NIR) to far-infrared (FIR), with the 1W IR LED typically operating in the near-infrared spectrum.

Working Principles of 1W IR LED

The 1W IR LED operates on the principle of the PN junction. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of photons. In the case of IR LEDs, these photons are in the infrared region of the electromagnetic spectrum. The efficiency of an IR LED is determined by its material composition, which affects the bandgap and, consequently, the wavelength of the emitted light.
