Introduction to Cree Infrared LEDs

What are Cree Infrared LEDs?

Cree infrared LEDs, also known as infrared light-emitting diodes, are a type of semiconductor device that emits infrared radiation when an electric current passes through it. These LEDs are widely used in various applications, such as consumer electronics, automotive, medical, and industrial fields. Compared to traditional infrared devices, Cree infrared LEDs offer several advantages, such as high efficiency, long lifespan, and compact size.

How do Cree Infrared LEDs Work?

Cree infrared LEDs are made of gallium nitride (GaN) or aluminum nitride (AlN) substrates. When an electric current is applied to the diode, electrons and holes are injected into the active region of the semiconductor. Due to the energy difference between the conduction band and the valence band, the electrons and holes recombine, releasing energy in the form of infrared radiation. The emitted light is typically in the near-infrared (NIR) or short-wavelength infrared (SWIR) spectrum, which is not visible to the human eye.

Advantages of Cree Infrared LEDs
