Write any two advantages of Light Emitting Diode (LED) over conventional incandescent low power lamps .

Text Solution

Verified by Experts

Advantages:
(a) Fast on-off switching capabilities.
(b) From the observed wavelength in the visible range, the wavelengths drifts only from 100Å to 500Å. Hence the light is nearly monochromatic.
(c ) LEDs consumes low power, operates under a very low voltage from 1.6V to 2.2V and have a long life.
