Introduction to Cree Infrared LEDs

What are Cree Infrared LEDs?

Cree infrared LEDs, also known as Cree infrared light-emitting diodes, are a type of semiconductor device that emits infrared light when an electric current is applied. These LEDs are widely used in various applications, including automotive, medical, industrial, and consumer electronics. Compared to traditional infrared lamps, Cree infrared LEDs offer several advantages, such as higher efficiency, longer lifespan, and smaller size.

How do Cree Infrared LEDs Work?

Cree infrared LEDs work on the principle of electroluminescence. When an electric current passes through the semiconductor material, it generates heat, which causes the electrons to recombine with the holes in the material. This recombination process releases energy in the form of photons, which are emitted as infrared light. Cree has developed advanced semiconductor materials and manufacturing processes to enhance the performance of their infrared LEDs.
