Introduction to Infrared LED 3mm

The infrared LED 3mm is a type of light-emitting diode that emits infrared radiation at a wavelength of around 940nm. It is characterized by its small size, typically 3mm in diameter, which makes it highly suitable for space-constrained applications. These LEDs are designed to operate at low power, which not only conserves energy but also generates less heat, making them ideal for sensitive electronics.

How Infrared LED 3mm Works

Infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in infrared LEDs is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which emits infrared radiation when an electric current is applied. The 3mm size of these LEDs is achieved by using a wafer-level packaging process that involves bonding the LED die to a tiny package.
