Who will wake up the sleeping city street lamp energy saving market?

According to incomplete statistics, the total amount of road lighting in Nanjing has reached 180 thousand, most of them for high-pressure sodium lamps, these lamps consume electricity is amazing. If you use a new type of LED lamps, can save about 50% of energy. Efficient energy-saving LED lights, the city has only one pilot installation, which is the reason why?

180 thousand cities lighting energy consumption amazing

Street lamp is one of the necessary facilities of city. According to incomplete statistics of the relevant departments, in 11th Five-Year, the Nanjing street lamp construction invested more than 700 million yuan in total, new lights, lights, road lighting has reached a total of 180 thousand lights. Among them, 100 thousand or so by the unified management of urban management department, the unit self built, landscape lighting and about 80 thousand.

Nanjing city street management office, said the person concerned, by the municipal unity of the tube to support the 100 thousand lights, most of the 250 Watt High Pressure Sodium lamp. Open 12 hours a day in winter, summer, open every day for 8 hours, an average of about 10 hours a day.

Because of the large number of street lamps, electricity consumption is also very alarming. To 250 watts per street lights, open every day for 10 hours to calculate, the cost of the daily consumption of the 180 thousand street lights on the need for 450 thousand degrees, the annual power consumption of up to 160 million degrees. According to the calculation of 0.5 yuan per kilowatt hour, the annual price of lighting street lamps is about $80 million.

If you use a more energy-efficient alternative LED high-pressure sodium lamp, how to save energy, it is understood that, if the use of LED lamps, 120 Watt LED lamps can replace the high pressure sodium lamp of 250 watts, and the lighting brightness. In other words, if the use of LED lamps, the annual street lamps can be energy saving 80 million degrees, save electricity costs about 40000000 yuan.

Jiefang Road, a new pilot installation of LED lamps

With the rapid development of China's LED industry, energy saving, environmental protection, green LED lamps in recent years by consumers are familiar with, but also quickly into a variety of commercial and civilian areas. In order to test whether this lamp is suitable for urban lighting, Nanjing last year in Jiefang Road pilot installation of some LED lamps. Actual use effect?

Liberation road about 400 LED lamps installed, but the trial for some time found that the existing LED lamps are not suitable for urban lighting. Nanjing Street Management Office official said, at the end of the first month of installation, maintenance personnel found that there are five or six LED lamps damaged. In the following year, the repair rate of these LED lamps is about 20%, much higher than the high pressure sodium lamp repair rate of 1%. High repair rate of LED lamps leads to high maintenance costs.

Secondly, the high price of LED city lighting is also unbearable. The source, at present, the civil LED 6 watt lamps each priced at about 100 yuan, 120 watts of city lighting when the price to 5000 yuan RMB, although each has now dropped to 4000 yuan, but still higher than the high pressure sodium lamp 1000 yuan each, the price is higher than the times.

Compared with the high-pressure sodium lamp, LED lamp is not save money, the pilot installation test can be said to be a failure. The person said.

Sleeping energy market needs to wake up

It is understood that in some cities in the field, LED lamps have also been used as a representative of high efficiency and energy saving, in the field of urban lighting street to promote the use of large-scale, but the results are not satisfactory.

Outstanding performance in the high cost of installation, repair costs. "Nanjing City experts said that the survey shows that the city is in need of lighting lamps with high power and stable and mature, and now as part of LED lighting technology is still not mature, in the process of showing a more serious" light "phenomenon, after a period of time, brightness will be more dark.

In addition, LED lamps in a long period of time, the cooling function is not as stable as the high-pressure sodium lamp, which led to damage to the lamp. At least from the current point of view, LED lamps are more suitable for personalized landscape lighting, civilian lighting, is not suitable for large-scale use of lighting in the field of lighting. "

China has always been a major street lamp power consumption in the city, lighting street lamp energy saving is also known as the sleeping market, then the sleeping market should be awakened by whom?

In this regard, Nanjing experts said that from the current situation of the development of LED industry, the annual production costs are significantly reduced, the production process is also rapid progress. Take the cost, for example, the cost of the LED lamp is decreasing at an annual rate of 20% - 30%. With the rapid development of production technology and technology, LED lamps will be more and more perfect, the price will be lower and lower, when it is expected to gradually replace the high-pressure sodium lamp.
