The Copenhagen climate summit held at the end of last year blew the horn of global energy conservation and emission reduction. In this context, LED lighting, as a new energy-saving and environmentally friendly alternative technology, has quickly become the focus of government, capital and business circles. By the end of 2009, China had become the most important LED lighting production base in the world, and the six ministries and commissions such as the National Development and Reform Commission jointly issued the “Opinions on the Development of Semiconductor Lighting Energy-Saving Industry†in October last year.
LED lighting can achieve energy saving
Currently, lighting accounts for about 20% of the world's total energy consumption. Statistics show that only LED street lights can save energy and save about one dam from the Three Gorges Dam every year.
It is precisely because of the energy-saving and environmental protection advantages of LED lighting that in recent years, its global output value has maintained an annual growth rate of more than 20%. China has also launched green lighting projects, semiconductor lighting projects, and the “Ten Cities and Ten Thousand Cities†plan. The development of the industry, the total output value of China's semiconductor lighting in 2008 was nearly 70 billion yuan. Moreover, various capitals have actively involved in the investment in the LED industry, and the scale of investment has grown rapidly. In the first half of 2009 alone, the total investment budget for LED projects launched across the country has exceeded 20 billion yuan.
“Although China's LED industry investment and capacity expansion are accelerating, more than 3,000 LED lighting manufacturers, but 70% of them focus on downstream integrated application, lack of upstream core technology, and due to the small size of enterprises and the lack of standards, products According to Wu Zhenle, Chairman of Shenzhen Hantian Technology Co., Ltd., many cities in China are currently carrying out LED lighting demonstration projects and alternative projects, but LED road lighting is still limited to branch roads, residential roads, pedestrian streets, and application areas. Limited, especially the current quality of LED lighting products is uneven. He said: "On one occasion, I drove through a city's LED demonstration road in rainy days, and more than 20 LED street lights only illuminate two or three shots."
The cost of using LED street lights is not high
At present, there is a misunderstanding of “the new technology is definitely costly†in the society, which makes the application of LED lighting in the domestic market urgently to be broken. "In fact, the high cost of LED lighting is a one-sided view." Wu Zhenle told reporters that the high-pressure sodium lamps commonly used in highway lighting are only a few hundred yuan a mile, and the LED energy-saving lamps cost a few thousand dollars, thus inferring the cost of LEDs. High, not true. Wu Zhenle further explained: “Traditional lighting requires laying cables. This is a costly one. At the same time, traditional sodium lamps have a short service life. Generally, lamps need to be replaced in a year or so, and the cost of repair and maintenance is high. These costs are included, LED lighting is not much different than traditional sodium lighting."
"LED lighting has the advantages of low power consumption and long service life. A traditional sodium lamp consumes about 2,300 yuan a year, while natural energy LED street lamps use solar energy, wind energy, fluid energy, etc., which completely saves this. Part of the cost. With the conservative use of Hantian Technology's LED street lights for five years, one shot will save 115,000 yuan." Wu Zhenle calculated this for us. "In addition, natural energy LED lights can also achieve the effect of stable lighting in rainy days." Wu Zhenle believes that LED lighting energy-saving industry should strengthen technological innovation and accelerate development.
