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.
Why a diode cannot emit?
A diode cannot emit light because it primarily functions as a semiconductor device that allows current to flow in one direction, facilitating electronic control rather than light emission. While certain types of diodes, like light-emitting diodes (LEDs), are specifically designed to emit light through electroluminescence when current passes through them, standard diodes do not possess the necessary materials or structure to produce light. Their operation focuses on rectifying current, rather than generating photons.
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.
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).
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.
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.
