In early 2009, in order to reduce energy consumption and promote the development of China's LED industry, the Ministry of Science and Technology launched the “Ten Cities and Ten Thousand†semiconductor lighting application demonstration city construction program, and Chongqing was listed as a demonstration city for energy conservation. Beibei District fully exploited the advantages of high-tech enterprises in its jurisdiction, and took the lead in fully introducing the LED green lighting source light source reconstruction, and its renovation scope covers all street lamps in the Beibei area.
Universal popularity of energy-saving street lamps
According to the plan, Chongqing will invest 50 million yuan in two years to encourage and guide the northern new district and 40 districts and counties in the city to apply LED lighting technology on a large scale in highway tunnels, municipal roads, industrial park standard factory buildings, underground parking lots and other fields. ,New product. Beibei District seized the opportunity of the country to promote the development of LED industry and the comprehensive improvement of Chongqing's urban environment, and proposed a plan to comprehensively renovate LED green energy-saving lighting street lamps within the region.
Beibei District introduced high-tech enterprise Chongqing Silian Optoelectronics Technology Co., Ltd., independently researched and developed green intelligent LED street lamps, and was jointly funded by Silian Group, and both parties jointly promoted the renovation of street lamps in the jurisdiction. From August of this year, the 119 street lights of the Beijiao District that did not meet the national illuminance standards were 10,803 street lamps of mercury lamps, sodium lamps and metal halide lamps, all of which were converted into LED green lighting sources.
At the same time, the existing street lamp 2985 ç› light source that did not meet the national illuminance standard of Caijia Tongxing Industrial Park was transformed into LED green lighting source to meet the national illuminance standard.
In addition to the streetlight renovation in Beibei District, Beibei District Municipal Bureau also included the Wuwu Expressway in the new construction area. The Beibei toll station of the Zhangwu Expressway passes through the Maanshi Bridge to the North Ring Road section for a total of 23 km (excluding the 4.1 km tunnel) and the exits along the ramps. A new LED street light will be built 1488 ç›, connecting Beibei to the core area of ​​the main city. The main and secondary trunk roads in Beibei District are newly built 787 miles. The Caitong Group consists of main and secondary trunk roads and 2815 new roads. According to the plan, by December, the total number of newly built street lamps in Beibei District will reach 18,878 baht, and new 5090 ç› street lamps will be built. All of them will be intelligently controlled and adopt LED green energy-saving lighting sources.
Intelligent first-class, advanced management
It is reported that by December of this year, the existing street lamps in Beibei District will all be upgraded. It is understood that compared with the street lamps installed in the past, the new street lamps have many advantages, and are green and more intelligent.
According to the relevant person in charge of Beibei District Municipal Administration, the new street lights have four advantages:
remote control. In the monitoring center, all the street lamps in the system are managed. With only a small amount of manpower, the tens of thousands of street lights in the jurisdiction can be precisely controlled. Specifically, each street light can be controlled and the status of each street light can be checked.
Timing dimming. Dimming operation can be implemented for each street light in the monitoring center, which allows the street lights to be adjusted according to different road sections and different seasons, which not only meets the lighting needs, but also can achieve energy saving on the basis of LED street lights. And can collect street lamp power, power and other electrical parameters, and store and display.
Group management. It is possible to group the street lights under the system, such as a certain road and an area, for unified management.
data collection. Users can choose the environmental parameters of the area where the street light is located, such as light, temperature, humidity, noise, etc.
Save nearly 20 million electricity bills every year
In addition to intelligence, another major feature of the new LED street light is power saving, long service life, up to 50,000 hours, low carbon environmental protection, and potential total cost advantages.
The relevant person in charge of Beibei District Municipal Bureau has calculated an account. The existing 119 streets and lanes in Beijiao District and the existing mercury lamps, sodium lamps and metal halide lamps in Caijia Tongxing Industrial Park total 13788ç›, which have not reached the national illumination standard. If the calculation is based on all national illumination standards, the annual input cost is 18.175 million yuan. All of them are converted into LED green lighting sources, and the total annual investment cost is 4.5 million yuan. Comprehensive comparison of economic benefits: Through calculation, theoretically, the annual management and maintenance costs and electricity costs can be saved to a total of 13.675 million yuan.
If the light source of the new 5090 street lamp is configured according to mercury lamp, sodium lamp and gold halide, it will reach the national illumination standard, and the total annual investment is 77.176 million yuan. All adopt LED light source lighting configuration, the annual total investment cost is 1.831 million yuan. Comprehensive comparison of economic benefits: Through calculation, theoretically, the annual management and maintenance fees and electricity bills can be saved by a total of 5.8857 million yuan.
According to comprehensive statistics, the total number of newly-built street lamps using LED green lighting fixtures is 18,878 baht, which can save management and maintenance costs and electricity costs totaling 19.56 million yuan per year. This street lighting alone can save 17.46.69 million kWh of electricity per year. The light source configuration has a repair period of 10 years, which is 2.5 times that of ordinary street lamps, and the energy saved for 10 years is enough to return the cost of the quadruple pads.
Built-in storage battery and charger, equipped with the function of over-charge and over-discharge protection and capacity display. It is used as working power supply for lightings, communications, laptops, and special instruments of emergency working, field working, press interviews, special vehicles and other fields.
It can be equipped with different type of storage battery such as lead acid battery, Nickel Cadmium Battery, silver zinc battery, Lithium Ion Battery and other storage batteries, providing various output voltage classes.
