As the global environment deteriorates, people are paying more and more attention to their own health, especially the impact of environmental factors on human health. For illumination sources, light pollution such as stroboscopic, ultraviolet radiation, electromagnetic radiation, thermal radiation and glare, with the advancement of mankind, light pollution has reached the point of affecting human health, and can no longer be ignored. And led as no stroboscopic, no ultraviolet radiation, no electromagnetic radiation, low thermal radiation and other characteristics, coupled with the application of light diffusion technology to eliminate glare, making it a true healthy light source.
According to the editor, the bright LED street lights are particularly attractive in the new campus of Tianjin Polytechnic University. These lamps are not only simple and beautiful in appearance, but also low in energy consumption, low in pollution and long in life. Today, the school's 1500-inch LED street light and 2000-inch LED indoor light have been in operation for a year, saving 1.3 million kWh compared to traditional street lights, equivalent to 500 households a year.
Mentioning these, teachers and students will naturally think of the director of the semiconductor lighting engineering R & D center of Tianjin University of Technology, doctoral student, master tutor Niu Pingjuan. Niu Pingjuan, 37, has been engaged in the research of silicon-based and compound-based optoelectronic devices and application system integration technologies for many years. He has participated in and undertaken research on several national projects, and applied for and obtained 7 patents. Niu Pingjuan calculated the account: assuming that 30% of global users turn to energy-efficient lighting products, a rough calculation can reduce 260 million tons of carbon dioxide emissions and 460 billion kilowatt-hours of electricity.
Niu Pingjuan established a research team of new semiconductor optoelectronic materials and devices, completed the development of a tile-level power LED with a combination of a new electroplating process and a flip-chip process, and applied it to the 2,800-mu new campus road construction of Tianjin Polytechnic University. It has become the largest semiconductor lighting demonstration project in the world, and its achievements have reached the international advanced level. She presided over the ultra-high-brightness epitaxial wafer power chip project and the high-end semiconductor lighting product development and industrialization projects, respectively, invested by Tianjin enterprises 100 million yuan and 220 million yuan, was included in the "Tianjin 20 independent innovation industrialization The implementation plan of the major project has entered the stage of large-scale implementation. The two enterprises supported by the transformation of this technological achievement have realized sales revenue of more than 50 million yuan.
The 11th Five-Year Plan for the promotion of energy-saving lamps in China is 150 million. However, in the past two years, China has promoted 210 million, saving 8.8 billion kWh annually and reducing carbon dioxide emissions by 8.8 million tons. It is estimated that during the 11th Five-Year Plan period, China will promote 400 million energy-saving lamps. Lu Wenbin, Director of the Energy Conservation and Emission Reduction Division of the National Development and Reform Commission, said that in the next few years, China will also formulate a road map and related policies for phasing out incandescent lamps in line with China's national conditions, and increase support for the conversion of incandescent lamps to energy-saving lamps. Strength: "Because China is a big producer of incandescent lamps, we say that we are still cautious about this, so our roadmap is in the process of being elaborated. The relevant supporting policies will also be followed up."
Today, China vigorously advocates the scientific concept of development and builds a harmonious society. Energy conservation and emission reduction has become an important strategic task. The development of the green energy industry is of great significance for energy conservation and emission reduction. In addition to the need for technical support in industrial development, a sound policy mechanism is even more essential. In the second half of the year, the status quo of the electroplating industry is even more severe. As the Asian Games will be approaching step by step, the energy conservation and emission reduction work will be stronger. Let us hope that the Chinese economy can really recover and the electroplating industry can really take off. high.
The Jsun 2.0 TV Soundbar uses spatial time delay to create room-filling, virtual surround sound Amplifier Stereo. The result is Audio Loudspeaker so realistic, you`ll reduce your entire collection of digital speakers to just this single piece. Even better, three preset listening modes are built in: Music Mode, Movie Mode, and Night Mode. You can now throw a party, transform your living room into a theater, and wind down all at the touch of a button. In each mode, you`ll experience the thrill that accompanies 60 watts and over 100db of pure, rich sound with less than 1 Percent THD.
