The construction and renovation of landscape lighting for buildings, green spaces and bridges along the Suzhou River in Shanghai is intensifying. From the end of this year, strolling along the banks of the Suzhou River at night, you can see the four major movements of energy-saving and environmentally friendly LED semiconductors, and form a beautiful cultural corridor.
The 3rd Shanghai LED Semiconductor Lighting Innovation and Application Forum, jointly hosted by the Shanghai Economic and Information Commission and the Putuo District Government, will open on November 6. At the news briefing held today, the reporter learned that in order to implement the basic national policy of energy conservation and accelerate the industrialization of LED R&D technology, Putuo District has decided to take the lead in promoting the application of LED technology and products in government-led construction projects. Following the public building road landscape project such as Zhenbei Road Overpass and Meichuan Road Leisure Street last year, this year's Putuo District started the Suzhou River Coast Landscape Lighting Project, the District Government Office Garden Lighting Reconstruction Project and the District Library New Hall Interior Lighting Project. In the middle, they have invested heavily in the application of new LED energy-saving technologies and products.
In order to vigorously develop LED emerging industries, Putuo District is planning about 150,000 square meters of Tiandi Photovoltaic Park and the future island photoelectric park park with 250,000 square meters of building area, and around the LED application center, the development of a nuclear and two-wing LED industry will be developed. pattern. At present, Shengyuan Optoelectronics Industrial Park, the US LED display private giant Daktronics China headquarters, Singapore Shengqi Group China headquarters have been stationed.
Shanghai is one of the seven key areas for the development of the domestic LED industry. At present, the development pattern of Shanghai LED Engineering Technology Center in Pudong Zhangjiang Hi-Tech Park and Shanghai LED Application Center in Putuo District has been initially formed.
The 3rd Shanghai LED Semiconductor Lighting Innovation and Application Forum is one of the high-end special forums of China International Industry Expo held next week. It will integrate LED high-end enterprises and experts from the United States, South Korea, Taiwan and other countries and regions to explore LED The road to industrialization.
Link: What is LED?
LED is semiconductor illumination, which is short for Light Emitting Diode. It saves 80% energy compared to incandescent lamps and 50% less energy than fluorescent energy-saving lamps. At present, LED luminous efficiency is higher than incandescent lamps, and it is expected to exceed fluorescent lamps in 2010. Because it is a solid-state light source, it has the characteristics of low working voltage, low power consumption, high luminous efficiency, many changes, environmental protection, long life, etc., and its life span is 20 times longer than incandescent lamps, 10 times longer than fluorescent lamps. The new darling of lighting is considered to be the best way to save energy and reduce energy consumption. According to experts' estimates, as long as one-third of the incandescent lamps are replaced by semiconductor lamps, the country can save 100 billion kWh of electricity every year, equivalent to one year of power generation in the Three Gorges Project. The LED has developed rapidly. In 1998, the white LED light efficiency was only 5 lumens per watt. In 1999, it reached 15 lumens per watt. Currently, the newly developed white LED of the international laboratory has reached the standard condition of 350 mA at operating current. A new record with a brightness of up to 155 lumens and a luminous efficiency of 136 lumens per watt.
The United States has developed a rainbow plan to announce the transformation of all public lighting into LED products by 2020. In China, the Bird's Nest, Water Cube and other venues built for the Beijing Olympic Games are heavily LED-based, and LED technology and product lighting will be widely used in the 2010 World Expo venues in Shanghai.
