Technical Information on LEDs


LEDs are very fast emerging technology in lighting that is considered as brilliant a technology breakthrough as the Edison light two centuries ago and is considered by the World Bank to be the solution for lighting up the 'bottom of the pyramid' (discussed below). LEDs are more commonly thought of as the tiny red and blue dots of light on household remote control units, but the new generation of LEDs give out useable white light that can be used in any light product.

LEDs are durable semi-conductors that provide one of the world’s most energy efficient light sources, with the newest models delivering around 70 to 100 lumensper watt. This means LED lights use approximately 10% of the energy consumptionof incandescent bulbs (normal light bulbs) and 30% of the energy of compact fluorescent lamp ('CFL') bulbs, respectively. The lights have very low failure rates (less than 1 in every 1000) and consume very little power (either from the grid or from solar recharging).

LEDs have a lifetime of over 30,000 to 50,000 hours, which means they last more than 50 times longer than incandescent bulbs and 10 times longer than CFL bulbs. Even after 50,000 hours, the LEDs don't just burnout - they just lose 10-20% of their rated intensity, which may not be noticeable in many applications. A summary of the differences between the performance and usage of THRIVE's LED home light compared to competitors' LED and solar lights is provided below:-

The Led Lights have already been put to use in a number of Domestic and Commercial premises. The source reports that they are saving a huge amount and also contribution to cleans the environment.

LED lights Durability and Toxic Free

They are light weight, impact resistance, waterproofing, anti-corrosion and do not contain any dangerous or hazardous material such as mercury or sodium. Many existing traditional lights including the energy saving CFL lights contain mercury. This very toxic material which is dangerous to us and the environment especially when they leak which often occurs when they are scrapped.
 
LED light usage will cut down Co2 emissions dramatically

LED lights will dramatically help cut CO2 emissions and green house gasses as they cut will lighting energy consumption up to 90%. LED will also conserve resources in the future as less lights will need to be manufactured and less waste will be produced.

Zero interference -

LEDs do not use ballasts which produce harmonic noise—or “hum.” LEDs do not produce electro-magnetic interference.

Task Lighting -

The bright, white LED lights produced by our Co. works especially well for task lighting and reading light. LEDs not only produce light more efficiently, they also have a tiny mirror that reflects light in one direction. A more directed light means less wasted light.

Significant Cost Savings -

LED lights offer significant cost savings compared to normal incandescent lights. By way of illustration, it estimates that approximately 35% of the electricity consumed  toward lighting, and if 35% of the light bulbs  were converted into LEDs, the country could save billion of Rupees in utility costs .

Key Environmental Benefits -

The use of LED lights will reduce the environmental damage that kerosene lighting creates. Using an LED light compared to a kerosene lamp saves one ton of carbon emissions over 3-4 years, which equates to US$ 30 of gold standard carbon credits. Therefore 10 million LED lights would save 10 million tons of carbon emissions, which would equate to US$ 300 million.

Key User Benefits -

Avoids the air pollution in the homes that is generated through kerosene lights - a recent report by the World Bank suggests that indoor air pollution from kerosene results in 1.6 million deaths worldwide every year. The World Bank also notes that 780 million people in the developing world, mostly women and children, are exposed to kerosene lantern fumes equivalent to two packs of cigarettes a day.

Key Commercial Benefits -

 *The Government of India through state governments currently provide subsidies on kerosene that costs Rs 75 each month (Rs 900 each year) for each family, assuming of 3 liters of kerosene for each family each month.
 
For every LED home light that the government can provide it could save Rs 900  p.a. Therefore if the State Government of Andhra Pradesh could provide 10 million LED home lights to every needy family in the state they would save billions of rupees of subsidy on kerosene a year.

LED Lighting:

LED lighting is the future of Lighting. These are most Energy Saving Lighting System. LED has very long life as compared to other type of Lighting. LED Lighting is used in modern Residential, Offices, Factories and commercial Places and many more areas.

Specifications and features of LED LIGHTS
