On March 12th, at the “2010 China Road Lighting Forum†held at Dongguan International Convention and Exhibition Hotel, the reporter found that about 80% of the speeches were related to LED street lights. In 2010, the work of “Ten Cities and Ten Thousand Miles†also entered an important implementation stage. Local governments outside the 21 pilot cities are still actively applying to join the pilot cities, and they are piloting locally, and they want to take the lead in LED development for their own cities. Machine, but whether LED street lights should be widely promoted, has become the most concerned topic of people from all walks of life at this meeting.
At present, some small companies believe that LED is an emerging, fast-growing, and low-end application industry, seeing the development prospects of LED street lights, blind investment, and directly into the field of LED street lights. In the interview, Wang Xiaoming, an engineer at the Shanghai Street Lamp Management Center, pointed out: "There are many small Led Street Lamp manufacturers that have changed from indoor lighting to outdoor lighting. Many of the light parts used in indoor lighting are used in indoor lighting. Meet the requirements of outdoor lighting."
Due to the imperfections and lack of LED street lamp standards and application standards, there is no evidence of purchase and maintenance. In addition, the staff of the street lamp management office said that because the country did not introduce standards for the maintenance of LED street lamps, it will encounter difficulties in the specific budget.
Therefore, Professor Lin Yandan, a member of the CIE International Lighting Committee, reminded everyone at the meeting that they should not only see the good aspects of LEDs, but ignore their current problems, and should treat LED road lighting objectively.
Chen Yansheng, chairman of the China Lighting Association, also held a similar view. He believes that the use of street lights is not determined by the government and should be decided by the masses. Whether you use warm white or cool white LED street lights, you can use them as long as they are suitable for the surrounding environment. Of course, the evaluation criteria should be in the hands of the masses.
At the same time, many Led Street Light companies have encountered certain problems in the development model. Nowadays, the most popular mode of LED street lamp enterprises is contract energy management. It requires street lamps enterprises to pay the entire project cost, and pay for the construction cost with the later saved electricity costs. The length of the cycle varies from 3 years to 3 years. More than 10 years. This directly tests the company's funds and brings a lot of risks. Recently, a new version of contract energy management has emerged - "user + bank + enterprise". Although the new version reduces the risk of the enterprise, according to industry insiders, this is not a relatively complete model, and the relationship between the company and the parties needs to be further explored.
In short, although China's LED street lamp industry is in full swing, it is still in the primary development stage. The chairman of Dongguan Qinshang Li Xuliang believes that the development of LED requires government departments to increase support for LED companies and projects.
Although LED street lights are facing difficulties, the experts, scholars and road lighting people from all walks of life are still optimistic about the development prospects of LED street lights. However, the problems that arise in the application at this stage cannot be ignored and cannot be avoided. If LED street lights want to illuminate the future, they must first illuminate the road under their feet.
The High-mast Lamp is generally refers to the new lighting device which is composed of the steel taper light pole and the high power combination lamp frame of 15 meters or above.It consists of lamp holder, internal lamp, electric rod body and basic part.Lamp head modelling can according to user requirement, surroundings, lighting need specific and definite;The interior lamps are mainly composed of floodlights and projection lamps.
