India has taken up a massive energy efficiency mission under which it will switch over to LED bulbs by the end of 2018.
The Centre has set a target to distribute over six crore LED bulbs through state-run Energy Efficiency Services (EESL).
4 crore 59 lakhs Light Emitting Diode, popularly known as LED bulbs have been distributed till now under the Domestic Efficient Lighting Programme.
It would result in a saving 6 billion dollars per annum.
The center has set a target of 1,000 days to provide electricity to 18,000 villages that are not electrified till now.
People can now check in real time how many villages are electrified, using specially created app ‘Garv Grameen Vidyutikaran’.
Need for LED Bulbs in India:
India is world’s 5th largest electricity consumer.
It is assumed that India will requires 1200 Terra watt in 2020.
These figures are always confusing, as we are far behind in the gap of supply and demand of electricity at this point.
The biggest benefit of LED lights is that unlike CFLs, LEDs do not contain mercury, which in fact is a great threat to the environment.
The combination of LEDs and solar energy will definitely alter the lighting industry. It will act as best option for the rural and remote areas where electricity supply is very erratic. Solar Energy also promotes green energy.
About LED Lamps:
An LED lamp is a light-emitting diode (LED) product that is assembled into a lamp (or light bulb) for use in lighting fixtures.
LED lamps have a lifespan and electrical efficiency that is several times better than incandescent lamps, and fluorescent lamps,.
The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023.
The initial cost of LED is usually higher.
A significant difference from other light sources is that the light is more directional, i.e., emitted as a narrower beam. LED lamps are used for both general and special-purpose lighting.
White-light LED lamps have longer life expectancy and higher efficiency (more light for the same electricity) than most other lighting when used at the proper temperature.
LED lights do not emit any UV radiation. Therefore, they are not harmful to people who have specific sensitivity for certain UV radiations.
Advantages of LED bulbs :
Reduces energy costs — uses at least 75% less energy than incandescent lighting, saving on operating expenses.
Reduces maintenance costs — lasts 35 to 50 times longer than incandescent lighting and about 2 to 5 times longer than fluorescent lighting. No bulb-replacements, no ladders, no ongoing disposal program.
Reduces cooling costs — LEDs produce very little heat.
Is guaranteed — comes with a minimum three-year warranty — far beyond the industry standard.
Offers convenient features — available with dimming on some indoor models and automatic daylight shut-off and motion sensors on some outdoor models.
Is durable — won’t break like a bulb.
Limitations:
LED lamps are high intensity point sources of light. As such looking directly at them is damaging for the eye.
LED efficiency and life span drop at higher temperatures, which limits the power that can be used in lamps that physically replace existing filament and compact fluorescent types.
The long life of LEDs, expected to be about 50 times that of the most common incandescent bulbs and significantly longer than fluorescent types, is advantageous for users but will affect manufacturers as it reduces the market for replacements in the distant future.
