With the rapid development of technology, infrared (IR) light has become an integral part of various industries, including medical, automotive, and consumer electronics. One specific type of infrared light that has gained significant attention is the 880 nm infrared LED (Light Emitting Diode). This article delves into the details of the 880 nm IR LED, its applications, and the industry surrounding its production and usage.

Introduction to IR LED 880 nm

The 880 nm IR LED is a type of semiconductor device that emits infrared light at a specific wavelength of 880 nanometers. These LEDs are known for their high efficiency and low power consumption, making them ideal for a wide range of applications. Unlike visible light, infrared light is not visible to the human eye, which makes it perfect for covert or unobtrusive uses.

How IR LED 880 nm Works

The 880 nm IR LED operates on the principle of the PN junction, which is a fundamental concept in semiconductor physics. When an electric current is applied to the PN junction, electrons and holes are created. As these charge carriers recombine, they release energy in the form of photons. In the case of the 880 nm IR LED, these photons are emitted at a wavelength of 880 nm, which falls within the near-infrared spectrum. The semiconductor material used in the construction of the 880 nm IR LED is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have been chosen for their ability to emit infrared light at the desired wavelength and their efficiency in converting electrical energy into light.
