It gives visible light when it is forward biased. Below are examples of how an led could be used with a computer.

They can also be used to display messages led boards new age brighter leds are used in the audi and bmw cars as sidelights.

What is the purpose of a light emitting diode. A light emitting diode led is a semiconductor electronic device called a diode that has the special property of emitting light. A light emitting diode led is an optical semiconductor device that emits light when voltage is applied. Light emitting diodes as well as semiconductor lasers are used to send data over many types of fiber optic cable from digital audio over toslink cables to the very high bandwidth fiber links that form the internet backbone.

A light emitting diode led is a semiconductor device that emits visible light when an electric current passes through it. When the light emits in the forward biased then it is called as a light emitting diode. A light emitting diode led is the special purpose diode.

Light emitting diodes are made from a very thin layer of fairly heavily doped semiconductor material and depending on the semiconductor material used and the amount of doping when forward biased an led will emit a coloured light at a particular spectral wavelength. In other words led is an optical semiconductor device that converts electrical energy into light energy. Light emitting diodes form the numbers on digital clocks send data from remote controls and light up traffic signals.

Light emitting diodes leds are widely used for indication purpose. When the diode is forward biased. It gives visible light when it is forward biased.

Light emitting diodes or leds serve many purposes such as statuses eg computer is powered on pc is reading from hard disk power and hdd leds. The light is not particularly bright but in most leds it is monochromatic occurring at a single wavelength. Find out how leds work.

The lighting emitting diode is a p n junction diode. Leds are commonly green amber or red but they can be an assortment of other colors as theyve become popular with case lighting. Short for light emitting diode led is a semiconductor that illuminates when an electrical charge passes through it.

Depending on which semiconductor is used we can change the color of the light produced by the led. The output from an led can range from red at a wavelength of approximately 700 nanometers. When light emitting diode led is forward biased free electrons in the conduction band recombines with the holes in the valence band and releases energy in the form of light.

It is a specially doped diode and made up of a special type of semiconductors.
