Introduction to 5mm Infrared Light Emitting Diode

The 5mm infrared LED is a type of semiconductor device that emits infrared light when an electric current is applied. It is known for its small size, typically measuring 5mm in diameter, which makes it highly suitable for integration into compact electronic devices. The infrared light emitted by these LEDs has a wavelength range of approximately 780nm to 1000nm, which is beyond the visible spectrum to the human eye.

Technology of 5mm Infrared Light Emitting Diode

The technology behind the 5mm infrared LED involves the use of semiconductor materials, primarily gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which are capable of emitting infrared light when an electric current passes through them. The structure of a typical 5mm infrared LED consists of a p-n junction, where the p-type and n-type regions are doped with different impurities to create a voltage difference. When an electric current is applied to the p-n junction, electrons and holes are injected into the depletion region. As these charge carriers recombine, they release energy in the form of photons, which are emitted as infrared light. The efficiency of the LED is determined by the quality of the semiconductor material, the design of the p-n junction, and the encapsulation of the device.
