gunn diode is transfered electron device & PIN diode is semiconductor device
Light Emitting Diode - LED
It is considered a diode, a Light Emitting Diode (LED).
That would be an LED or Light Emitting Diode an LED is a light
Light Emitting DiodeLight-emitting diode - a semiconductor that glows when a voltage is applied
Example sentence - The little red diode can be used as a pin on a tie.
LED: light emitting diode. It is a diode that emits light when current passes through it
S it has Clinton
No. Light Emitting Diode
A diode is a semiconductor device that allows current to flow in one direction only, while an LED (Light Emitting Diode) is a type of diode that emits light when current passes through it. In simpler terms, a diode controls the flow of electricity, while an LED produces light.
IR LED will be having connecting leads same as ordinary LED. When ever we use IR LED, which works like a transmitter we have to connect a photo diode as a receiver (very near to IR LED). So as we know IR LED keeps on emitting IR radiations photo diode will keeps on receiving, it in a reflecting surface. In case if the surface not reflect IR radiation(Black surface obsorbs IR). the input to the photo diode becomes nil, and photo diode wont work and hence the circuit. inform.mayaprasad@gmail.com
