Introduction to 3mm IR LED Industry

What is a 3mm IR LED?

A 3mm IR LED, also known as an infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. These LEDs are widely used in various applications due to their small size, low power consumption, and high efficiency. The 3mm IR LED is a popular choice in industries such as consumer electronics, automotive, medical, and security systems.

How Does a 3mm IR LED Work?

A 3mm IR LED consists of a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs), which emits infrared light when forward biased. The semiconductor material is sandwiched between two electrodes, and when a voltage is applied across the electrodes, electrons and holes recombine, releasing energy in the form of infrared light. The size of the 3mm IR LED is determined by the semiconductor wafer on which it is grown. The diameter of the wafer is usually around 3mm, which gives the LED its name. The small size of the 3mm IR LED makes it suitable for applications where space is limited.
