Light Emitting Diode Presentation

Definition

The word LED means “Light Emitting Device” or “Light Emitting Diode”. In French we use the word DEL, acronym for “Diode electroluminescente”.

The team of Our site. net has decided to use the word LED because it is much more used than LED. At a time when all the scientific publications are in English, it seemed more appropriate to take the step from the start. We apologize to all those who advocate the use of LEDs.

What is an LED?

An LED is an optoelectronic component. This means concretely that an LED is an electronic component that emits light.

Here is the symbol of an LED. It is that of a classic diode surmounted by two arrows. The latter symbolize the emission of photons (of light).

It would seem that this symbol is faithful to the last norm in force. You may encounter variants, both at the arrows and at the horizontal line.

Evolutions and perspectives

Since their invention, LEDs have constantly seen their performance evolve: their luminous flux has doubled every 18 to 24 months for 30 years. Meanwhile, thanks to their characteristics radically different from light sources traditional, LEDs have penetrated the market “niche”. The lights, the traffic lights, the flash of the mobile phones or the backlighting of the screens can be mentioned.

Different types

There are many types of LEDs. We can mention, among others, 5mm LEDs, power LEDs, red LEDs…

Physical properties

LEDs have physical properties accurate and which vary from one model to another, and even from one LED to another in the same batch.
