Stated very simply, an LED produces light when an electrical current passes through a microchip, which illuminates the tiny light sources called LEDs and the result is visible light.

Aug 14, 2025 · For an LED to work, electricity must flow from the anode to the cathode. The process by which an LED creates light is called electroluminescence. This is when a material emits light in …

Oct 15, 2024 · LED lights function using a simple mechanism involving two key components: a semiconductor and a current of electricity. Here's a more detailed look at how this works: 1. The …

Dec 3, 2025 · An LED emits light when an electric current passes through a semiconductor material, causing electrons to move and release energy in the form of photons—this is the light you see.

LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which …

Jun 16, 2025 · Inside an LED bulb is a semiconductor, a material that’s halfway between a conductor (like metal) and an insulator (like rubber). When electricity passes through this semiconductor, it gets …

The technology works by passing electrical current through engineered semiconductor layers, causing electrons to move and release energy as photons (light particles). The specific semiconductor …

Jun 3, 2025 · LED lighting refers to the use of a light emitting diode as a source of illumination. Unlike traditional incandescent bulbs or fluorescent lamps, an LED is a semiconductor device that emits …

May 6, 2025 · LED lights work by passing electricity through a semiconductor diode, creating light through a process called electroluminescence. The diode’s p-n junction releases photons when …

At its core, an LED is a semiconductor device that converts electricity into light. Unlike traditional incandescent bulbs that require a filament, LEDs use a semiconductor material to produce light.
