Advantages of solar LED street lamp and high pressure sodium lamp

Introduction: since twenty-first Century, the development of the industry is far beyond the energy consumption rate, solar power will become the new energy to replace traditional energy choice, "energy saving and emission reduction, green lighting", "ten city lights", the new rural construction, "solar building integration" project implementation promotes the development of new energy, LED industrial continuous high speed, low investment, green energy-saving projects become emerging high-tech industry high yield and high added value.

Comparison of solar LED street lamp and traditional high pressure sodium lamp

Then there is only one problem left, that is, solar LED street lamps in terms of cost and the traditional high-pressure sodium lamp and how?

It can be said that solar LED street lamp has the following advantages:

Advantages of solar LED street lamp and high pressure sodium lamp

1, solar LED street lamp is a clean renewable energy, compared to the traditional high pressure sodium lamp can reduce carbon dioxide emissions. If all of the 20 million street lamps in 2009 after the use of solar LED street lamp, can reduce emissions of carbon dioxide by 25 million 800 thousand tons, equivalent to the cost of carbon dioxide emissions of $10 billion 300 million.

2, the biggest problem of the traditional AC power street lamp is to lay the transmission and distribution cables, increasing the consumption of precious copper resources. Need to dig trenches to destroy the road. And these street lights or criminals the most ideal target of theft. The erection of solar street lights is very simple, just like a big tree like a tree, dig a pit, buried on the good.

3, AC power supply is 15% lower than the efficiency of solar power, that is to get the same output power, the use of alternating current to be more than the input power of 15%. But also the power factor of the problem, if not compensated, will lead to the increase of reactive power grid.

4, the biggest advantage of solar LED street lamp is no need to pay electricity bills. A 250 Watt High pressure sodium lamp costs about $766 a year. 20 million street lamp electricity expenditure is 15 billion 330 million yuan.

5, ordinary high-pressure sodium lamp life only 3000-5000 hours, while the LED life of up to 30000-50000 hours, and with the progress of technology, LED life is likely to be up to 100 thousand hours.

LED as a new type of lighting technology, with low power consumption, high luminous efficiency, good color, high reliability, small volume and light weight, energy saving and environmental protection, long life and other advantages, is the industry that is the main development direction of future lighting technology. Because LED is a cold light source, semiconductor lighting has no pollution to the environment, compared with incandescent lamp and fluorescent lamp, the power saving efficiency can reach more than 90%. Under the same brightness, power consumption is only 1/10 of ordinary incandescent lamp, fluorescent lamp 1/2, its energy efficiency is very impressive.
