Municipal building into the years to our rapid development, road lighting quality continue to improve the high-intensity gas discharge lamps are widely use to improve the investment environment to promote rapid economic development, and make life easier for the people to beautify the city and as an outward played an important role in the building of the modern city. But accompanied by a substantial increase of energy consumption, especially in recent years, energy prices greatly enhance the power consumption become a burden, therefore, the need to strengthen the technological improvements, to slow down the trend of energy consumption rising. In an era of global promote green lighting, energy-saving street lamps will inevitably become a trend.
Green lighting project in order to further implement and vigorously promote the implementation of the People's Republic of China Ministry of Construction to develop the "Eleventh Five-Year" urban green lighting project Plan "in the city lighting industry, road lighting design is the key to the city lighting energy saving of lighting The community has long recognized the importance of energy conservation, and began to promote the idea of green lighting.
In 2003, I used the main road of the city's World Bank Loan Project - China Street, Sports Avenue, Huai Nan Road lighting project the ILUEST intelligent lighting control device design, energy-saving effect is remarkable, reaching more than 20%. But there is a drawback, the cost of investment is too large, need 3-4 years to recover the cost, the good situation in the country to promote energy-saving lighting, the development and application of energy-saving products such as mushroomed endless stream used in the major cities.
But the manner in which the energy saving lighting source, energy saving and economic benefits, and whether the value of the use and promotion of, has not yet been proved, has not been peer recognition, and therefore has not been universal application. This article is based on data facts, scientific computing, describes two lighting source energy-saving methods, and discusses the feasibility and importance of using the premise meet traffic safety, energy saving and the quantitative analysis and promotion.
An intelligent energy-saving light box Road substation
(A) saving principle and the main advantage
Product saving principle: intelligent street light energy saving device equipped with a microcomputer control program using the dynamically optimized intelligent control technology to adjust the parameters of the electricity system in the dynamic changes, and optimized to protect the electricity system is always while working in the best condition to achieve the best energy-saving effect.
This street light energy saving devices for human-computer interface, flexible adjustment; does not generate high harmonics, the output is always full sine wave, non-polluting power grid, the user's cable signal, no any interference in the wireless signal will not be on the grid generate pollution, smart energy-saving products are environmentally friendly; energy consumption, long service life, improve equipment operating efficiency, reduce excess electricity costs; relatively low cost, a cost-recovery period is short, usually no more than 1.5 years, particularly suitable for the new line ; able to real-time monitoring, dynamic data, fault diagnosis and auto-protection parameters such as input, output current, voltage and power at the same time, stable operating voltage, more stable and reliable equipment operation; significant saving of up to 25% - 60 % for high grid voltage fluctuation phenomena, regulation and control devices according to the actual needs of the user's site, real-time online best lighting for regulation of the output voltage, and stability within ¡À 2.5%, and improve power quality, and thus stable The purpose of the working voltage.
Regulation device according to the user's actual lighting needs can also be multi-period energy saving voltage set by the program to meet the different light sources, the needs of different times, to achieve the best lighting state and the largest energy-saving rate.
Real-time regulator, control pressure, street lights after midnight supply voltage up to 250V, the best lighting voltage intelligent control device, able to extend the life of electric light, reduce lighting running and maintenance costs.
Intelligent lighting control. In order to meet the needs of different users on the lighting control, there are many models to choose from, such as: terminal control energy-efficient moving line mode; time control of the energy-saving operating mode; communication control energy saving operation mode. According to the actual situation, through the astronomical clock, the smart probe or internal programming, remote computer, remote control, implementation control, light control, programmed a variety of intelligent control. And according to the different time periods, different lighting, different brightness requirements.
Regulation and control devices using manual and automatic double-bypass system, lighting equipment to ensure uninterruptible power, the normal safe operation; serial communication telemetry, remote communication, remote sensing, remote control functions, and can be with the host computer networking, perform scheduling instructions center system Control.
Installation and commissioning easy, does not change the original wiring mode, maintenance-free, no need to set up a special management, reduce maintenance costs, reduce maintenance workload.
