LED Full form

The term ‘LED’ stands for Light Emitting Diode. This is a semiconductor source of light that emits bright light when electricity passes through it. The full meaning of LED lights is extremely popular in recent times due to their energy-efficient nature. Now it is widely used in most electronic gadgets such as watches, televisions, calculators, radios, and more.

Apart from the electrical uses, LED lights are in high demand in recent times. This up-to-date light saves 80% more energy than conventional fluorescent light sources. No wonder, this revolutionary item has made vast differences in the field of electronic gadgets and light sources. Now, most customers buy LED lights because of their durability and bright light source.

How LED Work? 

As the required voltage of current passes through the leads, the electrons reincorporate with the electron holes, this entire process generates energy and releases it in the form of photons. This is known as electroluminescence. The brightness and the colour of LED light are fixed by the power flown through the semiconductor.

What are the Notable Benefits of the LED? 

• Energy-Saving: This is one of the important reasons to consider LED bulbs. This technology is made to save 80% energy. LED TVs tend to save more energy than LCD TVs. Furthermore, LED energy doesn't generate heat and any odd sound.

• Long-Lasting Nature: LED lights are durable and run a long race. You can use a LED bulb for years, and that is at a reasonable price. 

• Nature-Friendly: Users are considering the LED bulbs as these items are nature-friendly and cause no damage to the environment. LED technology involves no cadmium, lead, or mercury. The best part of this non-toxic technology is that it can be recycled at a minimal recycling rate.

• Impressive Images at a Low Maintenance Cost: LED TVs come with impressive crystal clear images with bright colours. Besides, LED lights run along with a low maintenance cost.

What is the Key Purpose of the LED?  

The key purpose of LED is to offer brighter light at low current consumption. Nowadays, fluorescent bulbs are being exchanged with LED lights for their energy-efficient nature. LED TVs also consume low energy than LCD screen TVs and monitors. People are choosing LED lights due to their impressive durability and economical nature.

Types of LED

There are different types of LEDs or Light Emitting Devices available in the market. These differ in their shape, size and also the way their circuit has been formatted. They are affordable, have better illumination and efficiency. They also last longer, so they are durable. 

1. High Power LED: As the name suggests, these LEDs give higher levels of output. They consume more than 1-watt power. Since they provide higher output, the luminous intensity is also greater. They also have a longer life and are environment friendly than CFLs (Compact Fluorescent Lightbulbs)  or incandescent bulbs. They need a cooling system to be mounted on as they dissipate high amounts of heat. High Power LEDs are majorly used in street lights, lamps, traffic lights etc. 

2. Miniature LED:  These types of LEDs are common these days. They come in small sizes and are ready to fit. They do not require any heating or cooling device as they can be easily fitted into a circuit board. They come in 5V and 12V ranges in the market. They are used in a variety of electronic devices such as mobile phones, calculators etc. 

3. Application-Specific:  Then, some LEDs are made to carry out a specific function. Some examples of application-specific LEDs are given below- 

1. Flashing LEDs

2. Bi-colour LEDs

3. RGB tri-colour LEDs

4. Alphanumeric LEDs

5. Multicolour

What are the Flaws of LED Lights?  

There are so many pros and cons to using LED lights. However, when discussing the cons, what comes first is the initial price of the product. In recent times, LED lights are expensive. Apart from that, The performance of the LED lights completely depends on the temperature of the ambience where you are fitting the light. The bulb will get overheated and fail if the ambient temperature is high.

How are LEDs Different from CFLs or Incandescent bulbs?

LEDs, CFLs and Incandescent bulbs, all have different characteristics and this is why it is important to which one is the most suitable for use.

LEDs vs Incandescent Bulbs- 

Incandescent bulbs are those lighting devices in which light is emitted because of the heating of the filament. These are the oldest forms of bulbs. The bulbs have glass around them which contains a filament. When current flows through the filaments, it heats up to a certain temperature and the light gets produced. LEDs function differently. Instead of a filament, they have a diode. The diode contains two electrodes, anode and cathode. Light is produced when the current passes through these electrodes. Though Incandescent bulbs are cheaper than LED ones, LED bulbs are more common today because of their longer lifespan and greater efficiency. Incandescent bulbs produce much less light than LED bulbs as most of the energy is given out as heat. The average lifespan of a LED bulb is 50,000 hours whereas the average lifespan of an incandescent bulb is just 1,200 hours. Power used by LEDs to generate light is 6-8 watts. On the other hand, incandescent bulbs need about 60 watts of semiconductors power. 

LEDs vs CFLs- 

CFL bulbs are also called Compact Fluorescent Light bulbs. In CFLs, there is a tube containing argon and a small amount of mercury, which is generally folded and curved. When a current passes through the tube, the gases have a reaction that produces UV light. This is absorbed by the fluorescent material which then emits light. They are better than incandescent bulbs as they use much less energy to produce light. However, they are not quite as good as the LED bulbs and also have a shorter lifespan. The average lifespan of a CFL bulb is 8,000 hours which is comparatively less than the lifespan of a LED bulb which is 50,000 hours. Also, LEDs are durable than the CFLs as the glass can break easily and the mercury inside the tube is harmful to the environment.
