LED (Light Emitting Diode) lights for energy conservation

In India our demand for electricity increases at a rate of 9% per annum but the generation of electricity is at the rate of 6% only. Thus energy became an Economic Scare Commodity, with serious concern for all of us today.

Power Utilities experience the maximum peak during 6.00 P.M and 10.00 P.M. in India. The evening peak is dominated by the consumption of electricity for illumination by commercial as well as for religious purposes. In order to meet the peak load situation, Power Boards adopt load shedding and it is causing inconvenience to the industries on production and also for domestic users.

Promoting efficient use of energy and its conservation has been engaging the attention of the Government of India for quite some time. The study conduct by experts shows that there is enormous potential for reducing Energy consumption through energy efficiency measures. Energy efficiency will not only reduce the need to create new capacity, but will also bring in substantial environmental benefits.

In this context the Energy Conservation Act was placed on the statute book with avowed object to provide efficient use of energy and its conservation. The Act 2001 defined the term “energy” means any form of energy derived from fossil fuels, nuclear substances or materials, hydro – electricity and includes electrical energy or electricity generated from renewable sources of energy. It also establishes a bureau called the Bureau of Energy Efficiency to perform such function and exercise such power under this Act in particular to

LIGHTING will continue to be one of the important needs of human beings. The energy used for lighting in India is consuming large portion of energy produced compared to that in developed countries. Indian lighting system at present devours 17% of the total energy generated where as the corresponding share is only 8% in the developed countries. This is not due to large per capita consumption or even due to the immense population of India but it is due to the fact that most of our lighting installations are out dated and inefficient for example incandescent bulbs etc...

LED’s are emerging as the most efficient, cheapest source of lighting for everything, ranging from automotive lighting to recreational illumination. LED’s can be used to light up not just homes but also football stadium, monuments, commercial hoardings, streets, everything, LED’s are the future of lighting. They are very cost effective, long lasting and trouble free. They are particularly suited for rural lighting. The problem with rural lighting is two fold, the first is the obvious overall shortfall in electricity availability, and the second is inadequate finance to substantially increase generating capacity and also to distribute electricity to remote rural village. Lifeway Solar developed a unique LED home lighting system which can light up the entire village homes in India.

LED’s are semiconductor devices like transistors, and other diodes, LED’s are made out of silicon. What make an LED give off light are the small amounts of chemical impurities that are added to the silicon such gallium, arsenide, indium and nitride. When current passes through the LED, it emits photons as a by product. Normal light bulbs produce light by heating a metal filament until its white hot, while the LEDs produces photons directly and not via heat, so they are far more efficient than incandescent bulbs.

A study on KERALA STATE ’s Zero Watt bulb Market.

Kerala state consumers are using 8 lakhs Zero bulbs every year, So if it is replaced with 2 Watt LED Bulbs then the Govt. can save 13Watt x 8 lakhs x 24Hrs x 365 days = 9.11 MW Power.
To produce one MW power by using fossil fuels like Coal, Oil, Gas etc. the Govt. is spending around Rs. 6 Crore. So the savings for the state in a year by using LED bulbs will be 9.11 MW x Rs. 6 Crore = 54.66 crore.
