The transformation of the current generation of late the world's most energy-saving light sources to replace the traditional advantages of two years starting <br> <br> compared to the old high pressure sodium lamp, LED high penetrating power and low energy consumption and long service life, become. In response to the relevant requirements of the country and Guangdong Province, in November 2010, Zhuhai City signed a framework agreement for the construction of “Guangdong Province Green Lighting Demonstration Cityâ€, and signed the relevant responsibility book the following year, committing to complete the transformation of LED street lights in the city in 2013. . However, due to various reasons, the bidding for the project was not started until the end of 2012.
The renovation project was not carried out in time, mainly because of the discussion of the management model. According to the Zhuhai Municipal Garden and Forestry Bureau, the Guangdong Provincial Department of Science and Technology has designed a business model of “Contract Energy Management (EMC) + Supply Chain Management + Financeâ€, that is, the supply chain company is responsible for 75% of the financing, within the scope of the benchmark product catalog. For the selection and quality control of LED products, the local contract energy management company is responsible for 15% of the financing and implementation of the project. However, many cities have not accepted this model very much. After more than a year of investigation, Zhuhai has been greatly liberalized in the original model, that is, as long as the LED street lamp products purchased are recommended in the Guangdong Green Lighting Demonstration City. Within the scope of the Catalogue, and the completion of the transformation requirements within two years, the cost of the transformation shall be advanced by the winning bidder. After the completion of the transformation, the inspection shall be completed, and then the finance shall be returned in phases within 5 years. According to the relevant contract, the warranty period of the winning LED products is also 5 years, during which the maintenance costs incurred due to quality problems will be borne by the winning bidders.
Short warranty period and high maintenance cost LED street lights have a certain gap in energy conservation and emission reduction, and the relevant person in charge of Zhuhai Municipal Garden and Agriculture Bureau said. As far as the 26847ç› LED street lamp used in the first phase is concerned, it saves about 12.82 million kWh of electricity compared to the original street lamp, and the saving rate reaches 65%, but it does not achieve the expected energy saving effect.
In addition, LED street lights involve more management and maintenance issues. The person in charge said that the renovation of LED street lights is not simple. It is necessary to reconstruct the lamp pole lamps, design new lamp source production, sample testing, equipment supply, installation and commissioning, commissioning, delivery acceptance, maintenance, fault repair, personnel training, and After the end of the contract energy management period, the transfer of the light source, completion acceptance, etc., can finally achieve energy-saving replacement of LED lights.
“The maintenance rate of this batch of street lamps is 20%.†The relevant person in charge of Dehao Runda Electric Co., Ltd., one of the suppliers of LED street lamps in Zhuhai, said that LED street lamps have higher installation standards in poles, and Zhuhai belongs to typhoon. Ground, the destructive power of street lamps is very large. It is understood that the current LED street lamp power used in Zhuhai is about 150 watts per watt, and the price per watt is about 20 yuan. The price of a light bulb is about 3,000 yuan. Once the street lamp is damaged, the maintenance cost is at least 3,000 yuan.
The warranty period for the first batch of street lamps is 5 years. What to do after 5 years is an issue being discussed by relevant departments in Zhuhai. According to industry insiders, the longest life of traditional high-pressure sodium lamps is only 2 years. The real application of LED street lamps in China is only 4 years. Although it can theoretically guarantee 5 years, the stability and service life of the products have not been successful. In the case of the case, if the effect is attenuated after 5 years, the life will be reduced. "If you change it after 5 years, you will need a lot of money, and it will be difficult to manage the renovation project." The person in charge said helplessly.
The public data shows that the renovation of the first batch of LED street lamps in Zhuhai cost more than 88 million yuan, but the relevant department heads revealed that the actual funds spent exceeded this number.
The main city will be replaced next year. The most difficult problem in the renovation of LED street lights is the management problem. The relevant person in charge of the Municipal Garden and Forestry Bureau of Zhuhai said frankly that the renovation of LED street lights in various districts of Zhuhai is under the responsibility of the functional departments of each district. The department is mainly responsible for the main city of Xiangzhou. The renovation of LED street lights totals 50,000 baht. The first phase of the project covers about 27,000 baht of main roads. The second phase will cover all the urban roads and strive to be completed in the first half of next year. The second phase of the project is currently in the process of designing a tendering plan. It is expected that the first phase of the commercial management model will be followed, and official external tendering will begin in October.
