Introduction to High Power Infrared LED Diodes

High power infrared LED diodes, also known as infrared emitters or infrared LEDs, are semiconductor devices that emit infrared radiation when an electric current is applied. These diodes are made up of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared light. The key characteristics of high power infrared LED diodes include high brightness, long lifespan, and low power consumption.

Working Principles of High Power Infrared LED Diodes

The working principle of high power infrared LED diodes is based on the p-n junction, which is formed by combining a p-type semiconductor with an n-type semiconductor. When an electric current is applied to the diode, electrons from the n-type material move towards the p-type material, and holes from the p-type material move towards the n-type material. As these electrons and holes recombine at the junction, they release energy in the form of infrared light. The intensity of the emitted light is determined by the forward bias voltage applied to the diode. As the voltage increases, the current flowing through the diode also increases, resulting in higher power output. High power infrared LED diodes are designed to handle high currents and voltages, enabling them to emit intense infrared radiation.
