Advantages of light-emitting diode?

1- consumption of electricity is way less 2- last 10 to 20 times longer 3- heat emission is very low (less fire risk) ---------------------------------------------------- (MORE)

What is voltage required for light emiting diode and the current consumption of light emiting diode?

Typically, about 12 volts DC is the maximum input for led stripes for lighting. If its in a controller or a computer it's typically 5 volts. By controlling the voltage you can (MORE)

Does a semiconductor diode emit light when forward biased?

Not usually, unless you mean a LED. It depends of the kind of diodes. LEDs will emit light but not most regular diodes, though some may produce infrared light. In the case of (MORE)

What is light-emitting diode used for?

To begin with is was to replace incandescent lamps as indicator. But nowadays it is used for myriads of uses from indicator to lamps fixture for your House there are also spec (MORE)

What is liquid emitting diode?

To my knowledge, there is no Liquid Emitting Diode. There is a  thing called Light Emitting Diode (a tiny thing with two  terminals). When connected to a small electric curr (MORE)

How do you test a light emitting diode?

  You can test it by puting it in forward bias with a resistor. Use a dc voltage source of 5 volts and put it in series with 250 Ohms resistor. Or use 9volts with a 450 Oh (MORE)

Why ordinary silicon diodes do not emit light?

Silicon is opaque to all light (IR through UV).The bandgap of silicon is not high enough to produce visible photons, only IR photons.

What is the principle of light-emitting diode?

A light-emitting diode (LED) is a two-lead semiconductor light  source. It is a basic pn-junction diode, which emits light when  activated. When a fitting voltage is applied (MORE)
