Introduction to Infrared LEDs 850

What are Infrared LEDs 850?

Infrared LEDs, also known as infrared light-emitting diodes, are electronic devices that emit infrared light when an electric current is applied to them. The "850" in infrared LEDs 850 refers to the peak wavelength of the emitted light, which is 850 nanometers (nm). These devices are widely used in various applications due to their compact size, low power consumption, and high efficiency.

How Do Infrared LEDs 850 Work?

Infrared LEDs 850 work based on the principle of electroluminescence. When an electric current is applied to the diode, electrons and holes recombine at the PN junction, releasing energy in the form of photons. These photons have a wavelength of 850 nm, which falls within the infrared spectrum. The emitted light is invisible to the human eye, making it suitable for applications where visible light is undesirable or harmful.

Applications of Infrared LEDs 850

Infrared LEDs 850 find extensive applications in various industries due to their unique properties. Some of the most common applications include: 1. Remote Control Devices: Infrared LEDs 850 are widely used in remote control devices such as TVs, air conditioners, and other home appliances.
