Understanding IR LEDs

Infrared LEDs are semiconductor devices that emit infrared radiation when an electric current passes through them. They are composed of a p-n junction, where the p-type and n-type materials create a potential barrier. When the voltage across the junction exceeds a certain threshold, electrons and holes recombine, releasing energy in the form of infrared light. The 5mm IR LED is a popular choice due to its compact size, low power consumption, and cost-effectiveness. These LEDs are available in various colors, including red, amber, and green, but the most commonly used color for IR applications is red.
