In the realm of lighting technology, LED has emerged as a prominent player, revolutionizing the way we illuminate our surroundings. This energy-efficient and versatile lighting solution has gained immense popularity in recent years, with its applications ranging from household lighting to industrial use and entertainment. However, what exactly does LED stand for, and how does it work? Let’s delve deeper into the world of LED lights to uncover the full form and the science behind this innovative technology.
What is the Full Form of LED?
LED stands for Light Emitting Diode. It is a semiconductor device that emits light when an electric current passes through it. Unlike traditional incandescent bulbs that rely on heating a filament to produce light, LEDs generate light through a process known as electroluminescence. This efficient and durable lighting technology has become the preferred choice for various applications due to its numerous advantages over conventional lighting sources.
How Do LEDs Work?
LEDs function based on the principle of electroluminescence. When a forward voltage is applied to the semiconductor material within the LED, it energizes the electrons, causing them to move within the material. As these electrons recombine with electron holes, energy is released in the form of photons, which are the basic units of light. The color of the light emitted by an LED is determined by the energy band gap of the semiconductor material used in its construction.
