History of Infrared Infrared LED

Infrared infrared LED, also known as IR LED, was first developed in the 1960s. Initially, it was used in simple applications such as remote controls and optical communication systems. Over the years, the technology has evolved, and now it is widely used in various fields.

Working Principle of Infrared Infrared LED

Infrared infrared LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared light. The emitted light has a wavelength ranging from 700 nm to 1 mm, which is beyond the visible spectrum. The working principle of an infrared infrared LED can be described as follows: 1. When the anode and cathode of the LED are connected to a power supply, electrons are injected from the anode to the p-n junction. 2. The electrons move through the p-n junction and recombine with holes, releasing energy in the form of infrared light. 3. The wavelength of the emitted light depends on the material used in the LED. Different materials can emit light with different wavelengths, ranging from 700 nm to 1 mm.
