Corrosion Resistant Submerged Pump Corrosion-resistant submerged pumps rely on atmospheric pressure to raise the water level. With the movement of the piston, an approximate vacuum is created, and the water is forced up by the external atmospheric pressure. In principle, it can be divided into pneumatic pump, Centrifugal Pump, axial flow pump, mixed flow pump, screw pump and so on.

Recently, the 2012 Shanghai International New Light Source New Energy Lighting Forum jointly organized by the National Semiconductor Lighting Engineering R&D and Industry Alliance and the Reed Exhibitions Group was held in Shanghai World Expo. Dr. Yan Shenghu from the Urban Construction Department of the Ministry of Housing and Urban-Rural Development attended the opening ceremony and delivered a speech.
Dr. Yan Shenghu pointed out that semiconductor lighting is a strategic emerging industry that transforms traditional lighting. With the rapid advancement of semiconductor lighting technology and the continuous improvement of the market, the development of the global semiconductor industry has entered a new round of rapid growth. China will become the largest application market in the world.
In recent years, China has steadily promoted urban green lighting and continuously improved urban lighting facilities. The development of urban green lighting and the promotion of urban lighting energy conservation have become the consensus of the whole society. As of the end of 2010, among the 655 cities in China, there are more than 18 million street lamps, and urban lighting power accounts for about 40 of the total social lighting. During the 11th Five-Year Plan period, the promotion and application of semiconductor lighting in urban lighting has developed rapidly. According to the survey statistics of relevant units: the share of semiconductor lighting sources in urban landscape lighting accounts for more than 70, and semiconductor street lamps account for about 9 of the total number of street lamps in the country. During the 12th Five-Year Plan period, China's economic growth target will shift from quantitative growth to sustainable development, and green lighting will become an important part of the national industrial transformation. At the same time, China is currently in a period of rapid urbanization. The urban population will increase by more than 10 million a year, and the street lights will increase by about 1201.5 million per year. This process will last for 25 years or even longer. If all the new street lights in the urban roads are LED street lights, some old street lights and landscape street lights. Changed to LED lighting, its potential and development prospects are very impressive.
In order to promote urban lighting work in China, the Ministry of Housing and Urban-Rural Development issued the “12th Five-Year Green Lighting Planning Outline†in 2011, clearly proposing to further promote urban green lighting and improve urban lighting quality and energy conservation during the 12th Five-Year Plan period. Reduce the unit energy consumption of lighting, accelerate the demonstration and promotion of new products and technologies such as semiconductor lighting renewable energy, and realize the transformation of urban lighting development mode.
At present, we are actively formulating policy measures to promote the development of green buildings and urban green lighting. With the development of green buildings and green lighting, the demand for new light sources such as LEDs, new energy and new technologies will be greatly enhanced. At the same time, we will further promote the work of green lighting demonstration cities. It is expected that the 12th Five-Year Plan will be a five-year urban lighting transformation. The future LED lighting application hotspots will further shift from outdoor lighting to indoors. The demand of the international market and the guidance of domestic policies will become the key factors determining the growth rate of LED.
The development of green lighting is the future direction. One of the key technologies is the application of LEDs for lighting applications. The development of green buildings will greatly increase the demand for new sources of semiconductor lighting. We believe that the work of forming a synergy around green lighting will accelerate the spring of green lighting.
