What are the advantages and application of LED?

Advantages of LED Lights

• Long life. The components of an LED and the way that they generate light significantly extend the lifespan of these bulbs.
• Energy efficiency.
• High brightness and intensity.
• Exceptional colour range.
• Low radiated heat.
• Reliability.
• Instantaneous illumination.
• Directional lighting.

What are LED lights most commonly used for?

The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting.

What is LED and photodiode write down the applications of LED and photodiode?

In a nutshell, LED converts electric energy into light energy but Photodiode converts light energy into electrical energy….Comparison Chart.

Applications	Indicator in AC circuit, Alphanumeric and Numeric display etc.	Switching, high speed counting, ac coupled signalling etc.

How are LEDs used in lighting?

LEDs, which are also known as Light Emitting Diodes, burn light 90 percent more efficiently than incandescent bulbs. LEDs work by passing an electrical current through a microchip, which causes tiny light emitting diodes to illuminate. LED lights can last for years before they will need to be changed.

What is LED give its principle working construction merits demerits and applications?

Working Principle: A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.
