There is a growing awareness today of the growing adverse effects of pollution, unbridled depletion of green belts and rain forests and global warming. Flash floods and extreme weather changes have become the order of the day and if steps are not initiated now to ensure that the world becomes a better place to live in, there will be nothing left for future generations to lead a healthy life. Some of the environmentally friendly processes that have already been started by Government and private agencies and pressure groups are maximising recycling and reducing accumulation of non-biodegradable waste and lowering carbon footprint.
However, the advent of new and innovative technologies and putting in place suitable methods to reduce emissions of toxic chemicals and harsh chemicals in the environment have been a huge step in this direction. Another example of methods introduced to make Planet Earth a cleaner place to live in is a growing use of LED lights and an awareness of how they help in maintaining eco responsive surroundings.
- Energy efficient – LED lights are more energy efficient as more than 95% of their output is converted to light and the rest only to heat. In incandescent and fluorescent lights it is the opposite with 95% of energy consumed being dissipated as heat. Hence, LED lights draw much less power to provide the same level of luminosity. As a result, less overall electricity is drawn from power generating stations. Whether the power plants are run by burning fossil fuels as in thermal power or in hydro based projects, less power required mean lower greenhouse gas emissions.
Because of this factor, home owners or commercial establishments like restaurants can use decorative multi-coloured LED festoon lighting in their gardens or in their premises round the year without having to worry about high energy bills. The same goes for starlight lighting too where the main lighting diodes are in various shapes, sizes and colours, adding to the aesthetics of the surroundings.
- Less number of lights needed – LEDs have their light focus in one direction only and hence light up specified area more than traditional bulbs where the light gets scattered. Hence less number of lights or lower watt bulbs that draw less energy will offer the same level of light as higher powered incandescent or CFL lights. This helps to reduce power consumed, thereby being a benefit to the environment.
- Longer life span – On an average, a LED light lasts for about 10 years whereas a conventional light has a life span of a couple of years roughly, other things like number of hours of regular use being constant. This in turn reduces the need for periodic replacements and the overall number of LED units required thereby saving precious resources for manufacturing and packaging of the bulbs.
These are some of the factors that go a long way in saving the environment, simply by switching over to LED lights from energy guzzling incandescent and CFL lights.
