Definition :
The light emitting diode "LED" is a 2-leads semiconductor light emitter , which emits light when a suitable voltage is applied to the leads .
The LED is the most economic light source , for example : if an ordinary lamp based on a tingesting fuse powered on 25 watt , then a only 4 watt LED , although each one of them produces 190 lm light intensity ..
How does it work ?
