Introduction to Power LED Diodes A power LED diode, also known as a high-power LED, is a semiconductor device that emits light when an electric current passes through it. Unlike traditional LEDs, which are typically used for indicator lights and small displays, power LEDs are designed to produce higher output and are suitable for larger-scale lighting applications. The power rating of these diodes can range from a few watts to several hundred watts, making them ideal for street lighting, commercial buildings, and industrial settings.

How Power LED Diodes Work Power LED diodes operate on the principle of electroluminescence, where an electric current excites electrons in the semiconductor material, causing them to recombine and emit photons. The process involves the following steps: 1. Electrical Excitation: When an electric current is applied to the power LED diode, electrons and holes are injected into the semiconductor material. 2. Recombination: As the electrons and holes move through the material, they recombine, releasing energy in the form of photons. 3. Photon Emission: The photons are emitted in the visible light spectrum, creating the illumination effect. The efficiency of a power LED diode is determined by its ability to convert electrical energy into light, with higher efficiency resulting in less energy wasted as heat. Modern power LEDs can achieve efficiencies of up to 30%, significantly reducing energy consumption compared to traditional lighting sources.
