The Full Form of LED
The Full Form of LED is a Light Emitting Diode. LED plays an indispensable role today in electric and electronic apparatus. It’s used in electronics test equipment, televisions, radios, calculators, and watches, etc. They may also be used as the source of light because Light-emitting diode lamps provide long service life and higher energy efficiency as compared with fluorescent and incandescent lamps.
How LED Works
When a voltage of electricity has been applied to the leads, electrons recombine with electron holes and then releases energy in the shape of photons. This result is known as electroluminescence. The color of LED’s light is determined by the energy bandgap of the semiconductor.
A light-emitting diode is proved a revolutionary product in the stadium of origin of light. Its lamps are extremely energy-efficient, economical and long-lasting. As compared with conventional lighting bulbs and fluorescent light sources, it is nearly 80% energy efficient.
Characteristics of LED:-
- Low power demand: It requires less power forex in Television sets as compared with LCD televisions.
- Long life: When correctly set up, a Light-emitting diode can function for decades with very low maintenance costs.
- High efficacy: Light-Emitting Diode produces heat that is less as compared with normal LCD televisions and fluorescent lamps that increase the efficacy.
- Image Quality: They provide better picture quality as compared with LCD televisions.
Benefits of LED
1) Energy Efficient
Light-emitting diode requires power. For example, Light-emitting diode televisions are more energy-efficient than LCD and CRT televisions.
The light-emitting diode doesn’t produce heat, therefore it lowers the cooling loads.
The light-emitting diode doesn’t create buzzing noises and flickers etc..
Light-emitting diode lights are non-toxicity. It doesn’t contain mercury, lead or cadmium. The use of Light-emitting diode lights can decrease carbon emission.
3) Long Life
With appropriate installation, the Light-emitting diode may be worked for a long length of time with an extremely low maintenance cost.
4) Maintenance and Safety
Light-emitting diode needs very low maintenance costs. A very low recycling charge is also required by it.
A light-emitting diode is recyclable with an extremely low recycling fee.
6) Better Picture Quality
Light-emitting diode offers better picture quality.
LEDs have enabled text, video displays and sensors to be developed. Because of their high switching rates, it may be also beneficial in advanced communication technology.
