Advantages,Disadvantages and Applications Of LED

Advantages and disadvantages of LED

Advantages:

1.       Low working voltage and currents.

2.       Less power consumption.

3.       No warm up time.

4.       Very fast action.

5.       Emission of monochromatic light.

6.       Small size and less in weight.

7.       No effect of mechanical vibrations.
