What is a Power LED Diode?

A power LED diode is a type of light-emitting diode (LED) designed to emit high-intensity light. Unlike standard LEDs, power LEDs are capable of producing more luminous flux, which makes them suitable for high-brightness applications. Power LED diodes are constructed using advanced semiconductor materials, such as gallium nitride (GaN) or aluminum gallium indium phosphide (AlGaInP), which enable them to emit light in a wide range of colors.

Working Principle of Power LED Diodes

Power LED diodes work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing electrons to recombine with electron holes. This recombination process releases energy in the form of light. The intensity of the light emitted depends on the energy gap of the semiconductor material and the current flowing through the diode.
