They produce less heat: Because LEDs don’t rely on heat to create light, they don’t produce as much waste heat as incandescent bulbs.
They are more energy-efficient: LEDs convert more electrical energy into visible light than incandescent bulbs, making them a more efficient lighting option.Ģ. LEDs, or light-emitting diodes, are semiconductor devices that release energy in the form of light when an electric current is passed through them.Ĭompared to traditional incandescent bulbs, LEDs have a number of advantages:ġ. LED lights are increasingly becoming the lighting of choice for both residential and commercial applications. These photons are what create visible light. As electrons flow from one atom to another, they release energy in the form of photons. When electricity is applied to the anode and cathode, electrons flow from the anode to the cathode through the semiconductor material. The n-type material has extra electrons, while the p-type material has extra “holes.” The anode is made up of n-type semiconductor material and the cathode is made up of p-type semiconductor material. The anode is the positive terminal and the cathode is the negative terminal. How Do LED Light Bulbs Work? Properties And Working Principle ExploredĪn LED light is made up of two parts: the anode and the cathode.
