Introduction to Infrared LED 5mm

The infrared LED 5mm is a type of light-emitting diode (LED) that emits infrared radiation at a wavelength of approximately 850 to 950 nanometers. These LEDs are known for their small size, typically measuring only 5mm in diameter, which makes them highly suitable for integration into compact devices. The infrared radiation produced by these LEDs is not visible to the human eye, making them ideal for applications where stealth or covert operation is required.

How Infrared LED 5mm Works

Infrared LEDs work on the principle of the光电效应. When an electric current passes through the semiconductor material within the LED, it excites the electrons, causing them to move to a higher energy state. As these electrons return to their original state, they release energy in the form of photons. In the case of infrared LEDs, these photons have a wavelength outside the visible spectrum, specifically in the infrared region. The 5mm size of these LEDs is achieved through the use of advanced semiconductor manufacturing techniques. The semiconductor material used in these LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which have the desired energy bandgap for emitting infrared radiation.
