LED – Light Emitting Diode (An invention of conservation)

Light Emitting Diode was a discovery that changed the base of lighting industry. Light Emitting Diode (also known as LED) is p-n junction semiconductor which emits light once the electricity is passed through it. When the current is passed to the leads, the electrons release energy in the form of photons which creates the light and the process is called electro-luminescence.  

The electro-luminescence was discovered by H. J. Round in the year 1907. Round used a crystal of silicon carbide and a cat's-whisker detector to determine the process in reality. This discovery was the root which was needed in the invention of LED. Today, LED lightings are available for every possible utility. 

Some of the famous LED lights are as follows:

·         LED Area and Flood lights

·         35 watt LED retrofit kits

·         Parking lot lights

·         LED sports lighting

·         High bay lights

·         Low bay lights

LEDs are not only versatile but are used for a number of logical reasons. LEDs are the most efficient form of lighting and offer various ecological effects that help to reduce the exploitation of the planet earth. Some of the many appropriate reasons for LEDs usage are:

Environment Friendly

LEDs are made from toxic free material, which makes them eco friendly. Fluorescent lights contain a lot of harmful elements such as mercury which are highly dangerous for one’s health and also pollutes the environment. Whereas, LED lights are made from recyclable material which puts LED up front in this case.   

Free of Ultra Violet Radiations

Most conventional lightings emit ultra violet rays, the same rays which are found in sun which are capable of causing skin cancer. These rays are shielded by our ozone but the fluorescent lights produce these rays inside our homes. Thus, LED is better as it does not emit any kind of ultra violet radiation.

Works on low voltage

We are in phase of time where saving energy is very important as we have been burning our resources rapidly.  LEDs work on very low voltage saving a lot of energy than traditional lighting and saving energy means saving money as well, thus it becomes a better choice.

No wastage of energy

A traditional bulb or fluorescent lights burn a lot of energy in generating heat which is the reason why we feel hot if we touch a recently switched off light. But LEDs are efficient and does not waste any energy in the form of heat, thus making it a better source of light.

These lighting fixtures are highly durable and flexible. LEDs can withstand extreme weathers, which makes them the lord of conservation and savior of the planet. LEDs are better than any other forms of light and are the only form, which reduces the power consumption.
