Introduction to Cree Infrared LED Technology

What is Cree Infrared LED?

The Cree Infrared LED, developed by Cree, Inc., is a type of light-emitting diode (LED) that emits light in the infrared spectrum. Unlike visible light LEDs, which emit light in the range of 380 to 750 nanometers, infrared LEDs emit light beyond the visible spectrum, typically between 750 and 3000 nanometers. Cree, a leader in LED technology, has made significant advancements in the development of high-efficiency, high-performance infrared LEDs, which have found applications in a wide range of industries.

How Does Cree Infrared LED Work?

Cree Infrared LEDs work on the principle of electroluminescence, where an electric current is passed through a semiconductor material, causing it to emit light. The semiconductor material used in Cree Infrared LEDs is typically made of gallium nitride (GaN), which is known for its high thermal conductivity and excellent electrical properties. When an electric current is applied, electrons and holes recombine at the semiconductor's junction, releasing energy in the form of infrared light. The key to Cree's Infrared LED technology lies in the company's ability to optimize the semiconductor structure to achieve high efficiency and long lifespan. Cree's proprietary packaging technology also plays a crucial role in ensuring that the infrared light is efficiently emitted and directed towards the desired application.
