LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.

How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
What is a super luminescent diode?
With their emission properties Superluminescent Light-Emitting Diodes (SLEDs) are closing the gap between Laser Diodes (LDs) and Light Emitting Diodes (LEDs).They offer the broadband optical spectra of LEDs and the spatial coherence of LDs. Compared to Laser Diodes and LEDs, SLEDs can be understood as • Spatial coherent broadband laser diodes with a beam-like output • Temporal incoherent laser diodes with a broadband spectrum • Speckle-free laser diodes with a short coherence length • Spatial coherent LEDs with a beam-like output
What are two types of diode?
Light Emitting Diode (LED) & the Avalanche Diode. These are two types of diodes ,but there are more
Are diodes often used as switches?
Diodes perform a different function as switches. switches allow you to control wether or ot electricity is flowing. diodes only allow power to flow in one direction. A light emitting diode may be used as an indicator for wether or not power is flowing through a circuit.
Is LED stands for liquid emitting diode?
No. Light Emitting Diode
For what does LED lights stand for?
Light Emitting Diodes
Why are light emitting diodes bad?
They aren't bad.
What is a full form of led?
Light Emitting Diodes.
What has the author Joshua T Hall written?
Joshua T. Hall has written: 'Light-emitting diodes and optoelectronics' -- subject(s): Light emitting diodes, Optoelectronic devices
Where did Light Emitting Diodes get made?
They make them in many different places.
What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
What materials will emit light when electricity is added?
Light emitting diodes will emit light when electicity is passed through them.
Light emiting LEDS?
No, that is an auto-recursive expression. The LE of LED already refers to light emitting so what you are asking about is light emitting light emitting diodes! In any case, we have no way of knowing what you want to know about LEDs.
How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
What is the ayrton light?
It is stage/building light composed of L.E.D's (Light Emitting Diodes) the quantity of them make-up the brightness (accumulative).
Difference between light emitting diode and laser?
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
