The "shadow" under the LED light should not be turned a blind eye


In 2009, the Ministry of Science and Technology began to organize the adoption of LED in the application demonstration project of municipal lighting as a carrier, and selected 10 cities. Each city promoted the application of LED function lighting more than 10,000 baht. The plan is called “Ten Cities and Ten Thousand Cities”. At present, 42 cities including Guangzhou are included in the plan, but the promotion of LED street lights has attracted many doubts: Is it necessary to change LED street lights? It is not scientific to get together the street lights, and the LED street lights can't be heated. (April 7 "Yangcheng Evening News")

In Guangzhou, LED street lights were pushed to the top because of the Asian Games. For a time, praises such as “green”, “energy saving” and “high-tech” have become synonymous with LED, and the LED light shines everywhere. However, under the dazzling light of LED lights, there are “shadows” such as high cost, high maintenance, no more energy saving than high-pressure sodium lamps, and imperfect LED street lamp standards.

As for how many LED lights have been used in Guangzhou, how much it costs, there is no specific number on hand, but I believe it is not a decimal. Judging from the situation of Kunming City, the total cost of installing an ordinary street lamp is 15,000 yuan, and a single LED street lamp lighting equipment needs 5000 to 7000 yuan, and all installations need at least 1.8 to 20,000 yuan. The industry-recognized fact is that in addition to the lamp head, the LED street lamp has a Light Pole and a chip. At present, the price of a set of lamps needs to be more than 2,000 yuan, and the "hand and tail" is not light. For this reason, Kunming publicly opposed the installation of LED street lights.

It is not that the move of Kunming is to reject the specimens of LED street lights. But in fact, LED street lights are not favored all over the world. Relevant information shows that LED street lights in developed countries are still in the research and experimental stage. Guangzhou and other domestic cities will continue to promote the application of LED street lights at the cost of leaps and bounds. Whether it is the initial installation cost or the maintenance fee, it is inevitable that it will be out of the actual situation.

It is said that after the first batch of high-efficiency LED lights in Nansha is put into use, Guangzhou has planned to transform 100,000 street lamps in the main city this year, and it is expected to be LED lights. If you turn a blind eye to the "shadow" under the LED light, do not carefully consider the cost and other factors, blindly catch up with the "trends" that the LED industry sings, even at the expense of the blood, the essence is the lack of public decision-making, even the missteps, there is brewing Becoming a public account.

In fact, the LED street lights are big and big, regardless of cost, not only blindly from the so-called "trends", but also involve the problem of the construction of municipal facilities not careful. Such examples are not uncommon. For example, Dongfeng Road, Linjiang Road and other "Chinese lanterns" with a turnover of 40,000 yuan, Dongfeng Road, the middle of the flower base toss several times, a number of main roads, good flower base smashed for granite, and so on. The old and ruined municipal facilities must be repaired, no problem. However, if the icing on the cake is excessive, it will inevitably be blamed by the public for wasting the public slogan.

Urban beautification requires money, but money is worth the money. Numerous practices have proved that not every "trend" is correct. At least, we should think about it. The promotion of the use of LED street lamps in developed countries is willing to "lag behind". Why are we vying to taste the capital of "the feast of light"?
