"Regional forced replacement technology is not mature, and the technology is not high in LED lighting products. People can't doubt it. More importantly, the products need to consume a lot of non-ferrous metal resources, which is not in line with the national energy-saving and low-carbon environmental protection concept. Recently, Hu Jun, a person in charge of a power production company in Guangzhou, said in an interview that it is a hidden rule of the lighting industry to ignore the law and ignore the lighting efficiency. If it is not corrected as soon as possible, the economic losses will be Bigger.
The forced replacement referred to by Hu Jun refers to the notice issued by the Guangdong Provincial People's Government on May 23 this year, issued by the Guangdong Provincial Government (2012) No. 113, “Improving the Implementation Plan for the Promotion of the Use of LED Lighting Products in Guangdong Provinceâ€. Lighting is forcing the popularization of LED products.
Feng Rui, general manager of Foshan Meibo Lighting, said in an interview that the current national standard for road lighting should be revised. He told reporters that LED as a public lighting has certain dangers.
At the same time, Hu Jun has joined forces with industry insiders to write a letter to the Guangdong Provincial Department of Science and Technology and the Law Office of the Legal Office of the People's Government of Guangzhou Municipality, calling for a cessation of the complete replacement of LED lights and a strong questioning of the immature nature of the technology.
Insufficient cost savings
A paper notice triggered an earthquake in the industry.
People in the relevant lighting industry have raised objections and believe that replacing the LED lights as a public lighting system for street lamps will cause road safety hazards if their illumination is not up to standard.
Hu Jun said that not all environments are suitable for LED lighting. For example, urban main roads and secondary road lights are not suitable for LED lighting, because LED glare greatly exceeds national standards, and illumination is much lower than national standards. The method of lighting quality to save energy is too backward. If the number of electricity saved from the front is calculated, the electricity cost saved is far less than the cost of after-sales service. Urban lighting should aim to improve the level of intelligent management, rather than simply changing the light source.
Hu Jun particularly emphasized that the high color temperature of LED is pure white light, and the penetration is poor. It is especially obvious in rainy and foggy weather, which is not conducive to the safety of road driving. More importantly, LED street lamps cost a lot, and there is no standard accessory product to cause great pressure on after-sales service. Since LED lamps are different from traditional lamps, they must be replaced as a whole when energy-saving retrofits are made, increasing costs.
"The national regulations on urban road lighting design (CJJ45-2006) have strict regulations on the degree of contrast, uniformity, glare, etc., but the LED products currently promoted in the field of public lighting do not meet these standards." Hu Jun said.
According to Feng Rui, the Guangdong Province announced this year that it will force the replacement of LED lighting in the public sector in the province within three years. "The industry feels that this is a fantasy."
At the same time, the reporter saw an open letter to the Guangdong Provincial Government entitled "Guangdong will change all street lights into LED street lights will be a disaster!", registered by the company named "Risen Niko Lighting System Technology Co., Ltd." Weibo issued, the open letter also questioned the immature position of LED lights as road lighting: the ambient temperature is uncontrollable, the ability to wear fog can not be compared with the sodium lamp, which proves that LED as a street lamp will be a disaster.
Hu Jun pointed out that there are some design problems and product quality problems caused by the excessive road illumination and the lack of road illumination. Lamps, electrical appliances, and light sources are not uniform and have different efficiencies due to the use of products from different manufacturers. He said in a letter to the Guangdong Provincial Department of Science and Technology and the Legal Department Office of the People's Government of Guangzhou Municipality: "The LED frontier high-tech has been monopolized by foreign countries, and the products we want to promote are not technically."
No one pays attention to energy saving effect
The lighting enterprise management personnel interviewed by the reporter all objected to the energy-saving effect of LED lights. A common point of view is that the current lighting systems such as street lamps and other lighting systems are not replaced by technically immature LED lights, which can not only save energy and protect the environment, but will instead Increasing power consumption, combined with high replacement costs and high maintenance costs, will increase large financial expenditures.
Hu Jun calculated the account for the reporter: more than 80% of the existing urban roads and landscape lighting in Guangzhou use high-pressure sodium lamps, and its design life is 24,000 hours (5 years). However, due to the backwardness of China's urban power grid technology, the voltage fluctuation of the line greatly exceeds the international standard. Some urban areas fluctuate even more than 15% of the rated voltage. Especially in the latter half of the night, the grid voltage sometimes approaches 245V or more due to the reduction of the electrical load. The high-pressure sodium lamp causes light decay prematurely, and the life expectancy ends. The number of urban roads and landscape lights in Guangzhou is more than 100,000, and the annual maintenance costs are as high as tens of millions.
Lin Zhengang, an engineer at the Guangzhou Street Lamp Management Office, pointed out in his paper: "The application of LED street lamps in recent years has become the main solution or even the only solution for many street lamps to save electricity. Many cities have neglected the road lighting when formulating power-saving schemes. The analysis of the status quo and the high efficiency of high-pressure sodium lamps, one-sided pursuit of new technologies, new equipment, not only difficult to achieve the actual power-saving effect, but also cause waste. For example, LED street lights, is currently in the stage of rapid development, product updates, cost In the current stage, high-input LED street lights will soon become obsolete products with the development of LED technology and will soon be on the verge of elimination. Unsuitable light sources will also affect the functional indicators of road lighting."
Hu Jun said: "The competent authorities have seldom conducted in-depth investigations into the root causes of the loss and inefficiency. This is the idea of ​​'eat the royal grain' caused by the planned economy for many years. It is believed that the urban lighting construction and operation costs are national. The power saving section has nothing to do with it. In any case, the power supply department is also a state. When many cities have insufficient lighting costs, they use the method of turning off the lights to achieve energy-saving goals."
In response to questions raised by the industry, the reporter contacted the Guangdong Provincial Department of Science and Technology. A staff member named Chen asked the reporter to send an interview outline after asking for the identity of the reporter. After confirming the interview outline, the staff member said that he would "report to the leader and reply to the reporter." However, as of press time, the reporter has not received a reply from the Guangdong Provincial Department of Science and Technology.
