LED IR

An infrared light-emitting diode (IR LED) is a solid-state light-emitting (SSL) device that produces light in the infrared band or range of the electromagnetic radiation spectrum. IR LEDs allow for cost-effective and efficient production of infrared light, which is electromagnetic radiation in the 700 nm to 1mm range.
The various IR LEDs may produce infrared light of differing wavelengths, just like different LEDs produce light of different colors. IR LEDs are also useful in many types of electronics, such as remote controls for televisions and numerous other electronics. They are even in use in cameras; these infrared cameras use IR LEDs like a spotlight while remaining invisible to the naked eye.
The demand for IR LEDs is due to their versatility. For example, IR LEDs, in conjunction with several different types of sensors, are commonly in use in machine-to-machine environments and Emitting Internet of Things (IoT) applications.

An IR LED is a special type of diode or simple semiconductor. As I am sure you recall, electric current only flows in one direction in diodes. As the current flows, the electrons fall from one area of the diode into holes in another area. This is made possible by the electrons shedding energy in the form of photons, and this process produces light (electroluminescence).
It is also necessary to modulate the emission from an IR LED to use it in electronic applications to prevent spurious triggering. The modulation makes the signal from an IR LED stand out above the noise.
Furthermore, infrared diodes have a package that is opaque to visible light but transparent to infrared. Overall, with the extensive use of IR LEDs in remote controls, safety alarm systems, and just about every other electronic device, has made them extremely cost-effective.
