Buy IR LED – Introduction to the Infrared LED Industry

What is an IR LED?

An infrared light-emitting diode (IR LED) is a type of semiconductor device that emits infrared radiation when an electric current is applied. These devices are widely used in various applications, including consumer electronics, automotive, medical devices, and industrial automation. The term “buy IR LED” refers to the process of purchasing these infrared-emitting diodes for use in different systems and products.

How Does an IR LED Work?

An IR LED operates based on the principle of the PN junction. When a forward bias voltage is applied to the diode, electrons from the N-type semiconductor recombine with holes from the P-type semiconductor, releasing energy in the form of photons. These photons have a longer wavelength than visible light, which is why IR LEDs emit infrared radiation.

The wavelength of the emitted infrared light can vary depending on the material composition of the LED. Common wavelengths for IR LEDs range from 780 nm to 3000 nm, with 850 nm and 940 nm being the most popular for various applications.
