Technology of IR LED SMD

IR LED SMDs are semiconductor devices that emit infrared light when an electric current is applied. The key components of an IR LED SMD include the semiconductor material, the p-n junction, and the encapsulation material. The semiconductor material used in IR LED SMDs is typically gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs).

The efficiency of an IR LED SMD is determined by its wavelength, which ranges from 780 nm to 3000 nm. Shorter wavelengths result in higher efficiency but lower visibility, while longer wavelengths have lower efficiency but are more visible to the human eye. The encapsulation material is crucial for protecting the semiconductor material from environmental factors and ensuring the longevity of the LED.
