LED lighting energy-saving efficiency analysis

Source:

Energy saving and emission reduction have become current and future Community and problems to be solved in China's "top priority." Some areas have even taken the "rationing" really means. When people for energy conservation and emissions reduction "racked" the time, LED to the significant "energy-saving emission reduction" effect is quietly started a new revolution.
Power consumption of the LED only 1/10 of the traditional light bulb, life is 100 times of the traditional light bulb.
And is widely used in road, railway stations, squares and other public places compared to the high pressure sodium lighting, LED lamp power 40%~50% of high pressure sodium lamp. LED Street lamp 100 Watt equivalent to 250-Watt high pressure sodium lamps;
250 Watt high pressure sodium lamps every 3 hours for 1 kWh of electricity and 100-watt LED lamp per 10-hour 1 kWh of electricity consumption.
According to the city public lighting 1000 each lights 10 hours a day, price calculation 1:250 Watt high pressure sodium lamp electricity up to 3500 Yuan a day, electricity of more than more than 1.27 million Yuan a year. 100 watt LED Street lamp energy every day to 2,400 degrees, can save electricity more than 870,000 yuan a year, energy-saving efficiency of 68.5%.
High pressure sodium lamp life to 4,000 hours or so each Streetlight maintenance fee each year for an average 120 Yuan, calculated per 1000 lamp, maintenance costs of more than 120,000 yuan a year. LED Street lamp service life of 50,000 hours or more, can reach more than eight years of normal use, failure rate is very low.
According to the related institutions research estimates, as of 2010, if our existing 1/3 lighting using LED lights, can save 150 billion, calculated per kilowatt-hour by 0.8 Yuan, can save 120 billion yuan. According to the estimation of existing power structures, equivalent to the emissions from 25 million to 43.2 million tonnes of carbon dioxide reduction of 1.35 million tons of sulfur dioxide emissions.
