This is low carbon! LED lamp annual electric charge 1 million 500 thousand

Weihai Internet news, every time the night falls, a little streetlight is like the pearl inlaid in the night, illuminating the road of the city, and lighting the happy life of the citizens. However, with the extension of the urban extension and the upgrades of the urban construction, the longer the lighting lines are, the number of street lamps is increasing, the energy consumption is increasing, and the city finance has to take hundreds of thousands of yuan of electricity and street lamp maintenance costs every year.

In order to save energy and build a low carbon city, in recent years, Rongcheng has actively promoted and implemented various energy saving measures. The energy consumption of street lamps has been reduced greatly. The electricity consumption can be reduced by nearly 2 million degrees each year, and electricity cost can be saved by about 1500000 yuan.

Try new lamps and lanterns to save electricity from the source

To reduce the energy consumption of street lamps, street lamps and lanterns are fundamental. Li Dong, the deputy manager of the light road lamp company of the Municipal Construction Bureau, has been engaged in street lamps for 18 years. It has witnessed the whole development of Rongcheng street lamps. In his impression, Rongcheng street lamps have experienced three stages: incandescent lamps, high pressure sodium lamps and new energy-saving lamps. Incandescent lamps meet the requirements of low price and bright light. It seems to be very affordable. In fact, it is more power consuming and has long withdrawn from the street light stage. High pressure sodium lamp is used to make gold and white light. It has the advantages of high luminous efficiency, low power consumption, long life, strong fogging ability and no insect trap. It is the most used lamp at present. The power of the high pressure sodium lamp, as a street lamp, is usually 250 watts or 400 watts, and the power of the new LED and xenon lamp with the same lighting brightness is only 100 watts or 150 watts.

"LED lights and hernia lights are used for the first time in this year's urban street lights." Li Dong said that the city's north outer ring road, dawn South Road lights are xenon lights, LED lights, from the use of the situation, 100 watts of xenon lamp can replace 250 watts of high pressure sodium lamp, 150 watts of xenon lamp can replace 400 watts of high pressure sodium lamp; and the LED lamp is not bright, dark and other lighting uncertainties. Based on the LED lamp, the performance of the product is still unstable and the cost of investment is huge, and it is not considered to be used as a lamp lamp. "If the xenon lamp can achieve high light efficiency, long life and so on, we will consider further promotion." Li Dong said that they need to continue to explore the use of energy saving lamps for street lamps.

In order to save the lamps and lanterns, in addition to the new type of lamps and lanterns, the light road lamp company has also tried a new way of use. For example, each of the street lamps on Chengshan Avenue is originally a light bulb with 3 250 watts, and in this year's Chengshan Road comprehensive transformation, the new street lamps each install only 2 250 watts of light bulbs. Li said, don't see the light bulb less than one, because the lamps and lanterns are reasonably selected according to the actual conditions of the road, the design structure is more scientific, the same tile number is higher, the new Chengshan road lamp is not only brighter than the original, but also save electricity and reduce electricity consumption.

Install the long distance monitoring street lamp "see the sky" switch

In the energy consumption of street lamps, the operation mode is another important factor. In order to reduce the operating cost of street lamps, the street lamp energy saving monitoring system is adopted in Rongcheng, which makes the street light realize the "watch the day" switch, which effectively shortens the working time of the street lamp.

Before 2011, the street lamp system in the city was mainly controlled by time. The work flow of "to turn on the lights and turn off the lights" was carried out. The defect was that it was too rigid to change the weather condition automatically. In the evening, the light was bright when the sky was not dark; in the morning, the sky was bright, and the street lamp was still "sticking to the post" to waste electricity. After the use of street lamp energy saving monitoring system, the situation of waste energy is effectively controlled. "The street lamp 'watch the day' switch, every day the light and turn off the light time is different. On the morning of 2, the city residential construction bureau light street lamp company monitoring room, Li Dong showed the city street lights on the closing timetable, a year and 365 days, almost every day is different. Li Dong said that the specific time of these switching lights is based on the latitude and longitude of Rongcheng, sunrise and sunset time to measure and estimate. It is late in the summer, early in the summer, and the time of the street lights and the time will be different from autumn and winter, so it is more scientific and more efficient.

Through the energy monitoring and control system of street lamps, the workers do not have to take time and effort to open the street light when they meet the special weather condition or the temporary light. Only through the computer regulation and control system, the switch street lamp or the light time can be extended to facilitate the emergency lighting scheduling.

Try the electric humanization of the isolated light lamp

In order to save energy to the maximum, light road lamp company also tried several kinds of electricity saving forms, such as half - light, light - light, and so on, after 9 o'clock in the secondary road. "The implementation of such measures is to take into account that the opening of a street lamp at a distance does not affect the brightness of the road, and can meet the demand for road lighting." Li Dong said that the pedestrians and vehicles connected to the towns and towns around the urban area were less than 9 p.m., and the lamps could also meet the lighting requirements. In this case, the street lamps connected to the towns and towns around the city were all bright before 9 p.m. and after 9 late night. At present, this way of lighting is adopted by the roads connected to the towns and the towns around the urban areas, such as the Hai Xi Road and the West outer ring road. Li Dong rough calculation, according to the way of light lamps, only western outside loop and sea road one year can save electricity more than 360 thousand degrees, save about 300000 yuan of street lamp electricity.

"Through various energy saving measures, the energy saving effect of Rongcheng street lamps has been relatively remarkable." Li Dong said that in 2010, the Rongcheng street light was more than 760 million yuan in the year, and 4 million yuan in 2011. After the start of the energy saving system in 2012 and after a variety of electricity saving measures, the power consumption of street lamps has been reduced year by year. In 2014, the Rongcheng street light annual electricity consumption is 1 million 875 thousand degrees less than the 2011, and the electricity cost is less than 1 million 554 thousand yuan.
