Introduction to LED IR 3mm

LED IR 3mm, also known as an Infrared Emitting Diode, is a semiconductor device that emits infrared light when an electric current passes through it. It has a small size, typically measuring around 3mm in diameter, which makes it suitable for compact and portable devices. The 3mm wavelength falls within the near-infrared spectrum, which is invisible to the human eye but can be detected by various sensors and cameras.

How LED IR 3mm Works

LED IR 3mm operates on the principle of the PN junction. When an electric current is applied to the diode, electrons and holes are injected into the junction region. Due to the energy difference between the valence and conduction bands, these electrons and holes recombine, releasing energy in the form of photons. These photons have a wavelength of 3mm, which falls within the infrared spectrum. The 3mm wavelength is particularly useful for certain applications, as it allows for longer-range detection and better penetration through certain materials. This makes LED IR 3mm a preferred choice for various infrared-based technologies.
