LED lamp installation cost is too high to ten city lights of Kunming rejected

LED street is a semiconductor lighting lamp, with light emitting diode as the light source, because it is a solid cold light source, has the characteristics of no environmental pollution, low power consumption, high luminous efficiency, long service life etc.. Traditional street lamps often use high pressure sodium lamp, high pressure sodium lamp on the overall low efficiency caused by the great waste of energy. LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting.

2009 was known as the first year of white LED into the general lighting, the financial crisis highlights its importance. The implementation of the project of "ten cities" means that the semiconductor lighting industry has gradually entered the main battlefield of the industrial economy. Now it seems that the implementation of 21 cities as the leading semiconductor lighting project is in full swing. In this interview, we picked up a few typical cities on the "ten cities" project implementation status for your reference.

"Ten city lights" semiconductor lighting engineering goal is to 2011 in the pilot city for municipal engineering application of 6 million semiconductor lighting products, directly stimulating domestic demand 15 billion yuan; by 2015, the general lighting market of semiconductor lighting into 30%. Semiconductor lighting (LED) with its environmental protection, energy saving and long life characteristics, is considered to be the most promising high-tech green industry in twenty-first Century, the development of LED lighting has become the focus of the global lighting industry.

Saved 80 million yuan, but to spend 4 billion 800 million, such a thing in the current LED is stir on the street.

August 31, 2009, organized by the Ministry of science and technology "ten city lights" semiconductor lighting application project officially started. The goal of the project is that by 2011, 21 pilot cities for municipal engineering applications of 6 million semiconductor lighting products. Xinhua News said yesterday, as of now, our country has been in the 21 pilot city to promote the application of 1 million 600 thousand or more kinds of LED lamps, power saving more than 164 million degrees.

Need 60 years to recover the cost

Kunming Power Supply Bureau said yesterday, street lighting are utilities, electricity in accordance with 0.483 yuan / kWh charge. In other words, 1 million 600 thousand LED street lamp under 164 million degrees electricity, worth $79 million 212 thousand.

Then, what is the cost of LED street? Compared with the current streets and lanes in Kunming ordinary street how to spend? Kunming Lighting Management Co., Ltd. Assistant Purchasing Manager Xu introduced, the current Kunming street lamps, roughly 15 thousand yuan to install one, the cost of calculating the cable, installation, labor and other costs. If a single calculation of lighting equipment, about 2000 yuan. And a LED street lamp, single lighting equipment will require more than 5000 yuan, all installed down about $18 thousand. However, more than 5000 yuan LED street lamp is the lowest price, generally have to exceed this price, reaching $six thousand or seven thousand. In this calculation, the country's 1 million 600 thousand LED street lamps compared to ordinary street lamps, the need to spend more than 4 billion 800 million yuan.

Is said to save 80 million yuan a year to spend out of the 4 billion 800 million tariff calculation, need 60 years to recover the cost. So, LED street lamp life how long? Americans are asking for 30 thousand hours, down conversion is 3.4 years; some domestic LED street lamp manufacturers claimed to be able to reach the life of 12 years.

Kunming currently does not install

Kunming Lighting Management Co. Ltd., said yesterday that the French company after the white, the company is currently Kunming energy saving project, do not install LED lights.

Is currently in Kunming there is a new LED solar streetlight installed in Shilin County Road, Lu Fu Zhen Town, 118 lamp 30 watt lamp spent 790 thousand yuan. The general manager is responsible for this batch of street lamp of Kunming Xinguang energy environmental protection science and technology limited company Yin Nan said that if LED solar street lamp 140 watt (brightness equivalent to 400 watts of traditional lamp), it takes about 23 thousand yuan. At present, the main road in Kunming city is 400 watts of street lamps installed, the main road is not installed in the streets of 250 watts.

Province 80 million, have to spend 4 billion 800 million, the economic accounts who can understand. But why the Ministry of science and technology also pilot installation of LED street lamps? On this issue, we have some controversy.

In favor of the party believes that the current energy shortage, the installation of LED street lamp is from the point of view of energy saving, not only economic accounts. Moreover, the goal of the Ministry of science and technology, 6 million LED street lights will stimulate domestic demand of 15 billion yuan.

Opposition think, why not after the first developed LED lamp with low cost and large quantities for street lamps, the 4 billion 800 million can not spend for other purposes? Can even be used as research and development funding. A manufacturer said, there is a need to pay attention: LED street new comprehensive promotion, the traditional street lamp factory original country tens of thousands of township enterprises will not work, a large number of lamps factory workers brothers and engineers will face the risk of unemployment, light maintenance workers will all laid-off class.
