Cree infrared LED, also known as a Cree infrared light-emitting diode, is a cutting-edge technology in the field of lighting and illumination. These LEDs are designed to emit infrared light, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. This unique property makes Cree infrared LEDs highly versatile and suitable for a wide range of applications, from medical diagnostics to industrial automation.

Introduction to Cree Infrared LEDs

Cree, a leading global manufacturer of semiconductors and LED lighting solutions, has developed a range of infrared LEDs that offer exceptional performance and efficiency. These LEDs are based on Cree's proprietary GaN-on-SiC (Gallium Nitride on Silicon Carbide) technology, which allows for high-power, high-efficiency infrared emission. The Cree infrared LED is known for its long lifespan, low thermal resistance, and excellent color consistency.

How Cree Infrared LEDs Work

The working principle of Cree infrared LEDs is similar to that of traditional LEDs. They consist of a semiconductor material, usually gallium nitride (GaN), which emits light when an electric current is applied. In the case of infrared LEDs, the semiconductor material is specifically designed to emit infrared radiation. The GaN-on-SiC technology used by Cree ensures that the infrared LEDs can operate at high temperatures and with high efficiency.
