Energy saving lighting to illuminate the sunrise industry

In the colorful light, the waste of energy is accompanied by the increasing urbanization. Echoes, street lighting is becoming an emerging industry, but also one of the most promising emerging industries in the energy efficiency industry

When the night falls, the city will always show another person in a different way - the streets lit, dazzling dazzling night...... This has become a symbol of urban prosperity or not.

However, in this colorful light, the waste of energy is accompanied by the increasing urbanization. Echoes, street lighting is becoming an emerging industry, but also one of the most promising emerging industries in the energy efficiency industry.

Energy saving lighting

In recent years, with the rapid development of China's economy, energy efficiency is low, the energy structure has become an important issue to achieve sustainable economic and social development.

At present, China's power supply and demand situation is grim. According to the development of China's urban lighting data, the total number of street lamps for 9186356 lamps, road lighting total funding of up to $5 billion 200 million 910 thousand. Construction statistics show that the city lighting (landscape lighting and street lamps only calculate functions such as lighting) the annual electricity consumption accounted for about 4% of the total generating capacity to 5%, equivalent to the construction of the Three Gorges hydropower project put into production after the annual power generating capacity (84 billion degrees). This series of data show that as the image of urban development, lighting electricity saving significant.

With the development of the country during the "11th Five-Year" energy-saving index and requirement for energy-saving lighting, currently the country is forming a lighting atmosphere, exhibition in the field of energy fist choice for many enterprises. They focus on the important role of the energy market in the future economic development, increase investment in energy saving technology and R & D.

Digital street lamp came into being

Energy saving is also productivity". How to carry out the deployment, the effective integration of limited energy, China and even the world today, the issue of universal concern, we need to give more attention and investment.

As the production of power products business - the United States and the United States Power Equipment Co., Ltd. is a street lamp power saving management system, remote monitoring system for the main energy-saving products. They are committed to the research and development of digital control system for street lamps, through the trial and test in the market, get a good effect, power-saving function, good performance, saving up to 30% - 45%.

In the current market of domestic and foreign energy-saving road lighting project, whether it is multi loop wiring, thyristor chopper products, electronic ballast, ballast type reactance saver and a series of energy-saving technology in the seeking of the product, or replace the high-pressure sodium lamp energy-saving lamp products, there are many problems. For power saving, safety, reasonable price and ensure the normal lighting effect, can not have both the effect.

In successfully passed the national certification center energy certification, NC type energy-saving lighting has been objectively recognized in the use of many of the city, stable and reliable work, convenient operation, high saving rate, good energy saving effect, high recovery rate of investment. The street lamp system output power can be flexibly set according to road conditions and different periods of people and traffic conditions, and greatly reduce the heat consumption and lamps and greatly prolong the life of lamps, is a kind of high efficient and energy-saving lamp energy saving system. Since the second half of 2006, the project woomi CNC control system has to take energy-saving street lamp, Changsha airport central air-conditioning system energy-saving lamps, Jiaozuo energy-saving energy-saving lamps, Yantai Rizhao Port Authority and Beijing Miyun lamp energy-saving lamps, sales and benefits rise.

Technology and cost confusion

According to the general manager of woomi Power Equipment Co., Ltd. Yan Xiaoying, at present, domestic lamp energy saving system regulated products are mostly poor results, mechanical wear or wear contact problems, the working life is short; at the same time switch leads to voltage swell and sag, and the voltage regulation is the jump, will stop production, lamps flicker, power factor ratio is low, three-phase unbalance, slow response speed and waveform distortion, there are a lot of harmonic, phase is not protection, in the high current working conditions, easy to produce electromagnetic interference and transient interference, the power factor compensation is not reasonable, the service life of equipment and a short street caused greater harm.

Cost is another factor in the energy saving street lighting industry. It is understood that some of the cost of energy-saving lamps than ordinary high pressure sodium lamp about 80%. Peking University School of physics, vice president Shen Bo believes that China's generating capacity of about 19% for lighting, now is the main lighting fluorescent lamp and high pressure sodium lamp, although the cost is spread out to fill the electricity savings, improve technology, reduce the cost but a pressing matter of the moment or the entire energy-saving road lamp industry. According to the relevant research results, if half of the current light can be replaced by energy-saving lamps, the annual savings of electricity may reach the Three Gorges power station generating capacity.
