3mm Infrared LED: A Compact and Efficient Lighting Solution

Introduction to Infrared LEDs

In the realm of lighting technology, the 3mm Infrared LED (Light Emitting Diode) has emerged as a compact and efficient solution for various applications. These tiny diodes emit infrared light, which is invisible to the human eye but can be detected by sensors and other electronic devices. The 3mm size makes them highly versatile and suitable for integration into a wide range of devices, from consumer electronics to industrial equipment.

How 3mm Infrared LEDs Work

3mm 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 these LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when excited by an electric current. The small size of the 3mm LED allows for a high density of diodes on a single chip, making them ideal for applications requiring a large number of sensors or indicators.
