Global Warming and LED Lighting

By Wande Osunrinde

Global warming can simply be defined as the periodical rise in the temperature of the lower earth as a result of the increase in human activities through industrial revolution. As a result there is an increase in the level of greenhouse gases.

Normally, the atmosphere is warmed through a process called greenhouse effects. Ultraviolet rays passes from the sun through a thin layer or blanket and this layer contains the mixture of water vapour and carbon dioxide, methane, nitrous oxide and ozone. And the presence of these chemicals in the atmosphere is naturally regulated for human survival.

But the presence of this thin layer does not allow the ultraviolet rays to penetrate the earth directly; some of the rays are trapped or reflected down and therefore keep earth temperature at a tolerance level of about 16 degree.

The rise in the industrial revolution has drastically increased the quantities of greenhouse and other dangerous gases penetrating the thermal blanket. The resultant effect of these activities has lead to an increase in the level of green house created and with its own corresponding increase in the earth temperature. Because the earth is being warmed beyond a responsible proportion, there is an increase in the level of ecological disaster than what the ability of a normal human being can comprehend.

To make the earth save for all, approaches to manufacturing are being reformed by inventing more appliances that emits less acidic gases, and one of the latest of the inventions is LED lighting. LED lighting stands for Lead Emitting Diode; it is another form of lighting that is gradually replacing the light bulb invented by Thomas Edison several years ago.

The invention of light bulbs or incandescent light is trailed by tales of woes. It has actually been discovered that its demerits far outweighs the merit and it not safe for human use because of its high energy consumption, short life span, because they produce massive carbon dioxide, they are labeled as an environmental hazards.

And therefore LED lighting is actually designed for those who are interested in preventing global warming because LED lights are very efficient, LED light has also been discovered to convert all their energy into light and can only supply light where it is needed.

LED lighting is another efficient way to save money not only for individuals but for the nation as a whole, because LED lighting is very easy to manufacture and could be combined with solar panels to generate cheap electricity to areas where electricity is a luxury.

Environmental protection as a guard against global warming, manufacturers of lighting appliances are concentrating more on the production of LED lighting because they produce less garbage and does not contain any mercury which can be found in fluorescent lighting.
