Infrared LEDs (IR LEDs) are transforming the technological landscape, enabling a broad spectrum of applications with their ability to emit light in the invisible infrared range. From remote communication and surveillance to healthcare and industrial automation, these compact and efficient devices are driving innovations in how we interact with and utilize technology.

What Are Infrared LEDs?

Infrared LEDs are semiconductor-based light sources that produce light in the infrared spectrum, covering wavelengths between 700 nm and 1 mm. Unlike visible light, infrared radiation is invisible to the naked eye but can be detected by specialized sensors and cameras. These LEDs are highly efficient, consume minimal power, and respond quickly, making them indispensable in numerous modern applications.

Structurally, they resemble standard LEDs, with their performance and wavelength determined by the semiconductor materials used.
