QUE SIGNIFIE LED EN ANGLAIS

Diode électro-luminescente

Light-emitting diode

Une diode électroluminescente est une source de lumière semi-conductrice à deux conducteurs. Il ressemble à une diode de jonction pn basique, qui émet de la lumière lorsqu'il est activé. Lorsqu'une tension de montage est appliquée aux conducteurs, les électrons peuvent se recombiner avec des trous électroniques dans le dispositif, libérant de l'énergie sous forme de photons. Cet effet est appelé l'électroluminescence, et la couleur de la lumière est déterminée par l'espace de bande d'énergie du semiconducteur. Une LED est souvent de petite taille et des composants optiques intégrés peuvent être utilisés pour façonner son rayonnement. Apparaissant comme des composants électroniques pratiques en 1962, les LEDs les plus anciennes ont émis de la lumière infrarouge à faible intensité. Les LED infrarouges sont encore fréquemment utilisées comme éléments d'émission dans les circuits de télécommande, tels que ceux des télécommandes pour une grande variété d'électronique grand public. Les premières LED à lumière visible étaient également de faible intensité et limitées au rouge. Des LED modernes sont disponibles à travers les longueurs d'onde visibles, ultraviolets et infrarouges, avec une luminosité très élevée. Les LED précoces ont souvent été utilisées comme témoins lumineux pour les appareils électroniques, en remplaçant les petites ampoules à incandescence.

A light-emitting diode is a two-lead semiconductor light source. It resembles a basic pn-junction diode, which emits light when activated. When a fitting voltage is applied to the leads electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light is determined by the energy band gap of the semiconductor. An LED is often small in area, and integrated optical components may be used to shape its radiation pattern. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs.

Stephen Baldwin

I believe I have a calling. Do you know what that calling is? To stand up in a new and hard core, radical way for the Lord. In the process, if I insult a couple of people, if I offend a couple of people, and if I got to shake it up a little bit, as long as it is led by the Holy Spirit, amen.
