I don't know how much the city government is going to launch the LED project when we are so poor. How much is the budget? Or is it just because of face engineering? ! ! The street light is replaced with an LED. What about the original street light? It is a great waste to know that Hailufeng has a lot of land and there are no street lights in N places. Even the most common high-pressure sodium street lamps are not popular, you have to go to the LED, waste not to say, or swollen face to fill the fat. Recently, there has been a lot of debate about the rationalization of LED lighting initiatives in municipal projects in Guangdong Province. In the numerous open letters reflecting the issue, this opening statement is particularly prominent.
In the eyes of many ordinary people, domestic LED companies are still stuck in the stage of packaging and processing, and can't talk about development. At the same time as LED power saving, there is still a problem that the price is high, the maintenance cost is extremely high and there is no standard. Generally speaking, the domestic LED industry is very chaotic.
However, after the end of the ten-city project in 2009, the new round of local government's enthusiasm for promoting LED street lights is heating up. Recently, Xintai, a representative of the People's Congress of China Southern Power Grid, pointed out that under the same lighting intensity, LED street lights are actually not more energy efficient than high-pressure sodium lamps. In addition, the specifications of LED lamps of various manufacturers are very different at present, and it will be very troublesome once maintenance and replacement. Because it is not fully standardized like a high-pressure sodium lamp, it is easy to buy a replacement product after the original bulb is broken.
LED lighting renovation projects under the leadership of the government are in full swing, whether the urban street lights LEDization should be one size fits all? Is the LED street light better than the current high-pressure sodium lamp in terms of cost performance? Is there any evidence for the merits of LED street lights?
Is the LED lighting renovation engineering train driving too fast? These questions, perhaps experts and scholars, industry companies have their own opinions.
LED lighting of street lamps is waiting to be discussed. LED street lights can not be forcibly promoted. Now the quality of products is uneven and the price is expensive. The ten-city project is also a repeated defeat and repeated defeats. Professor Yang Zhengming, the director of the Southeast University and the honorary chairman of the Jiangsu Provincial Lighting Society, was a bit excited when he talked about this issue. He believes that LED is a good source of light and should be used well, but it has not been fully utilized. Whether to replace existing high pressure sodium lamps should be determined by the market. High pressure sodium lamps and high pressure mercury lamps have coexisted for 10 years. If you really want to replace it, I think ceramic metal halide lamps are better than LED lamps. In the view of Professor Yang Zhengmin, LED is a good source of light for spotlights and downlights, and as a streetlight, it still needs to develop for five or six years. When the market is truly mature, the quality of LED street lamps needs to be improved.
The advantages of LED street lights have not yet been realized. LED lights are dimmable and can be operated dynamically, while traditional HIDs do not. Professor Zhu Shaolong, a professor of lighting engineering at Fudan University and a consultant to the China Lighting Society, believes that intelligent lighting is the best way to use LED street lights. When the car came, the lights were brighter, and the lights were dark after the car went. Some cities in foreign countries have begun to adopt such technology. At present, domestic enterprises may have reached such technical requirements, but it requires sensor control and capital investment, so there is no example application.
At this stage, LED street lights are not new in technology compared with previous years. In addition, LED street lights are more controversial in terms of light efficiency, cost performance, evaluation and other key indicators.
The LED is a point source, and if it is not applied well, it is prone to glare. Moreover, from the perspective of the entire industrial chain, LED street lamps involve radiators and drivers, and the cost of replacing all high-pressure sodium lamps is not necessarily more economical. Wu Mingfan of Hangzhou Mingda Photoelectric LED Products Research Institute believes that LED street lamps have high technical requirements, and large-scale replacement is still needed.
In addition, current indicators for evaluating road lighting use illuminance rather than brightness. Professor Zhu Shaolong pointed out that illuminance can replace brightness only when the light distribution reaches the bat-type light distribution. The actual situation is because the brightness measuring instrument is expensive and the popularization rate is not high. Therefore, for convenience, the brightness is generally replaced by illumination. There are loopholes in the evaluation system, and the quality of LED street lights is difficult to guarantee.
On October 10, Qinshang Optoelectronics announced that it won the bid for the 46,000-inch LED streetlight renovation project in Qingyuan City, Guangdong Province. On November 21, the company again announced that it was awarded the HNZM-LED for the LED lighting contract management project of the lighting test section of Shanghai-Nanjing Expressway. -1, the estimated contract amount is about 4.5 million yuan.
On November 26th, Dehao Runda announced that the company as the leader won the bid for the renovation and installation of 30,000 LED street lights for public green lighting in Zhuhai City (one bidding section). The winning bid amounted to 4,608,900 yuan, accounting for approximately 2011. Audited operating income of 1.5.
On the same day, Hongli Optoelectronics announced that the company as the leader won the bid for the renovation and installation of 30,000 LED street lights for public green lighting in Zhuhai City (two bidding sections). The winning bid amount was RMB 42.393 million, accounting for 7.82 of the company's 2011 audited consolidated financial statements.
However, behind the seemingly beautiful scenery of enterprises, they also have their own hidden concerns.
On the second day after the announcement of the bid-winning announcement, Hongli Optoelectronics announced that the Zhuhai Construction Project Bidding Management Office received a 30,000-inch LED streetlight renovation procurement and installation project (two tenders) for public green lighting in Zhuhai. Complaints are currently under investigation and the suspension of the bidding notice for this tender project is suspended.
One word, chaos. When asked about the current LED street light market situation, Liang Gangquan, director of Qinshang Optoelectronics Sales Business pointed out: Although the government is supporting, there is no uniform standard for LED street lights, the price is chaotic, the quality is chaotic, and the market is naturally not good. According to him, Qinshang Optoelectronics originally expected LED street lamp sales to increase by 30 this year, but it may be lower than expected.
For the lack of national LED street lamp standards, Wang Hao, director of the product of Zhejiang Sunshine Lighting (600261.SH) LED outdoor lighting marketing center, said: First of all, the government level is multi-head management, each is a battle, each place has corresponding standards, and has not reached the unified Secondly, the lighting manufacturers have different production processes. They are useful for COB, but also have a single watt of high power, and modular, and varied. Finally, the results reflected in the terminal application are incomprehensible. Poor. According to him, Sunlight has also participated in the drafting of national LED related standards, but the current state is in its infancy, and it is not certain when the system text can be formed.
The LED industry generally believes that the industry standard is difficult to produce. In the long run, the market is becoming more and more chaotic, and the development of the enterprise must be greatly affected. The LED streetlight project that is quickly launched is only a temporary flower.
The government has re-directed less intervention. The government has its own views on the government's strong push for LED lighting renovation projects. The government's promotion and subsidy can solve the urgent needs of enterprises, but whether they can fundamentally save the enterprise is another matter. Whether the government-sponsored products are qualified or not can only be tested by time. Zhang Feng, general manager of Hangzhou Hongjian Liming Technology Co., Ltd. is worried that the government will not cure the problem, and excessive administrative intervention may make the LED industry become the second photovoltaic. At the same time, he also pointed out that in the face of such an impetuous market, enterprises need to clarify their own development direction, rather than being supported by government support projects.
Of course, the government's support will definitely help the LED industry and promote the development of the industry from a macro perspective. However, the current situation is that local governments only pay attention to prices and do not emphasize quality, and they do not start from the perspective of whether they are affordable. The market is turbid, and the government’s lack of guidance will only get more mixed. Wang Hao is not worried.
