An LED (light-emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current.
LED display of a TI-30 scientific calculator (c. 1978), which uses plastic lenses to increase the visible digit size X-Ray of a 1970s 8-digit LED calculator display Until 1968, visible and infrared LEDs were extremely costly, on the order of US$ 200 per unit, and so had little practical use. [28] The first commercial visible-wavelength LEDs used GaAsP semiconductors and were commonly used as ...
LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions.
A Light Emitting Diode (LED) is a special type of PN junction diode. The light emitting diode is specially doped and made of a special type of semiconductor. This diode can emit light when it is in the forward biased state. Aluminum indium gallium phosphide (AlInGaP) and indium gallium nitride (InGaN) are two of the most commonly used semiconductors for LED technologies.
Light Emitting Diode (LED): What is it & How Does it Work?
A light-emitting diode (LED) is a small electronic device that emits light when an electric current flows through it. LED works by passing electricity through a semiconductor, which releases energy in the form of light. This process makes an LED highly efficient, durable, and versatile, finding its applications in everyday devices such as smartphones, TVs, and home lighting systems ...
The meaning of LED is past tense and past participle of lead. When to Use Lead or LedCurrent blends LED lighting with digital networks to make commercial buildings and industrial facilities more energy efficient and productive. Learn more.
LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.

Cold remedies are almost as common as the common cold. But do they work? Nothing can cure a cold, which is caused by germs called viruses. But some remedies might help ease your symptoms and keep you from feeling so bad. Here's a look at some common cold remedies and what's known about them.
The common cold is an infection of the nose and throat, called an upper respiratory tract infection. More than 200 viruses can cause the common cold. Rhinoviruses are the most common. A cold virus enters babies' bodies through the mouth, eyes or nose. Once infected by a virus, a baby's body usually can fight off that same virus in the future. That's called immunity. But because so many viruses ...
