Infrared LEDs 850: The Cutting-Edge Technology Revolutionizing Remote Control and Sensor Applications

Introduction to Infrared LEDs 850

What are Infrared LEDs 850?

Infrared LEDs 850, also known as 850nm infrared LEDs, are a type of light-emitting diode that emits light at a wavelength of 850 nanometers in the infrared spectrum. These devices are widely used in various applications due to their unique properties and advantages. Unlike visible light, infrared light is not visible to the human eye, making it ideal for applications where privacy and security are paramount.

How Do Infrared LEDs 850 Work?

Infrared LEDs 850 work by converting electrical energy into light through the process of electroluminescence. When an electric current passes through the semiconductor material within the LED, it generates heat, which causes electrons to recombine with electron holes. This recombination process releases energy in the form of photons, which are emitted as infrared light.

The semiconductor material used in infrared LEDs 850 is typically a compound semiconductor, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to efficiently emit light at the desired wavelength of 850 nanometers.
