What is LED?

The Light Emitting Diode (LED) is one type of semiconductor diode, which emits the light of a particular color whenever current flows through it in the forward direction.

Applications of LED:

1) Smartphone and Television Displays
2) For Lighting (At home and offices, at street lights)
3) For communication
4) In Display Boards
5) As an indicator (At traffic signals, In vehicles)

Advantages of the LED:

1) Energy Efficient (Low Power Consumption)
2) Longer Life Cycle
3) Fast Switching
4) Small Form Factor
5) Better Controllability (For brightness)

Different LED Specification (usually found in datasheets)

1) LED Current (Maximum allowable forward current)
2) LED Voltage (LED Forward Voltage Drop)
3) LED Wavelength
4) Luminous Intensity
5) Viewing Angle

Different Types of LED:

1) Through-hole LED
2) SMD LED
3) High Power LEDs
4) Chip on Board (COB) LEDs
5) RGB LEDs
6) Alphanumeric LEDs

In this video, the working of the LED, Different Types of LED, the advantages of the LED, and different applications of the LED has been explained.
