"I don't know if the city government is launching the LED project when we are so poor. How much is the budget, how much is the return? Or is it just because of the face project?!! The street lamp is replaced with the LED, then the original street lamp? The sea and the earth are still known. There are N more places without street lights, this is a great waste. Even the most common high-pressure sodium street lights are not popular, you have to go to the LED, waste not to say, or swollen face to fill the fat." Recently, around Guangdong The rationality of the promotion of LED lighting initiatives in municipal projects in various stages has been discussed. 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 “Ten Cities and Ten Thousand Miles†project ended in 2009, the new round of local government's enthusiasm for promoting LED street lights is heating up. Recently, Xintai, a representative of China Southern Power Grid, pointed out: "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. Once maintenance and replacement, it will be very troublesome. It is not completely standardized like a high-pressure sodium lamp, and 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 LED 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 train renovation project "train" too fast? These questions, perhaps experts and scholars, industry companies have their own opinions.
Street lighting LEDization is open to question
"LED street lights can not be promoted at all. Now the quality of the products is uneven and the price is expensive. The 'Ten Cities and Ten Thousand' project is also a 'failed battles and repeated defeats.'" Southeast University Ph.D., Honorary Director of Jiangsu Lighting Society Professor Yang Zhengming was a little excited when he talked about this issue. He thinks that LED is a good light source and should be used well, but it has not been fully utilized for mass promotion. "It is up to the market to decide whether to replace the existing high-pressure sodium lamp. The high-pressure sodium lamp and the high-pressure mercury lamp have coexisted for 10 years. If it is really necessary to replace it, I think the ceramic metal halide lamp is better than the LED lamp." In the view of Professor Yang Zhengmin, LED It is good to use as a light source 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 been exerted. LED lights are dimmable and can be operated dynamically, but traditional HID will not work." Professor Zhu Shaolong, Ph.D., Department of Lighting Engineering, Fudan University, and consultant of China Lighting Society believes that intelligent lighting is LED street light. The best way to use it. "The lights are bright when the car arrives, and the lights are dark after the car goes. 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 instance. 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.
"LED is a point source. If the application is not good, it is prone to glare. Moreover, from the perspective of the entire industry chain, the LED street lamp involves the radiator, the driver, and the cost of replacing the high-pressure sodium lamp is not necessarily more economical." Hangzhou Wu Mingfan of Mingda Optoelectronics LED Products Research Institute believes that LED street lamps have high technical requirements, and large-scale replacement is still needed.
In addition, the current evaluation of road lighting indicators uses "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. 
Is the LED train renovation project "train" too fast?
