This is low carbon! LED light year electricity tariff 1 million 500 thousand

Weihai network, when the night falls, the lights in the night as tiny spots inlaid in Pearl, lit up the city's roads, also lit their happy life. However, with the extension of urban expansion and upgrade of city construction, street lighting line becomes longer, the number of street lamps also doubled, power consumption increases, the municipal financial year to take electricity and street maintenance costs hundreds of million yuan.

In order to save energy and build a low carbon city, in recent years, Rongcheng actively promote the implementation of a variety of energy saving measures, a significant reduction in street light electricity consumption, electricity consumption can be saved nearly 2 million degrees per year, saving electricity costs $about 1500000.

Try new lamps from the source saving

To reduce the energy consumption of street lamps, street lamps are fundamental. The deputy manager of the Municipal Housing Bureau bright lamp company engaged in Li Dong street for 18 years, witnessed almost the whole development of Rongcheng street, in his impression, Rongcheng street lamp has experienced three stages: incandescent lamp, high-pressure sodium lamp, energy saving lamp. Incandescent light in line with the low price, according to the requirements of light, seemingly very affordable, in fact, more power consumption, has long been out of the street stage. The utility model has the advantages of high luminous efficiency, low power consumption, long service life, strong ability of penetrating fog and no inducing insects, etc. the utility model has the advantages of high luminous efficiency, low power consumption, etc.. As a street lamp high-pressure sodium lamp power is generally 250 watts or 400 watts, while the same lighting brightness of the new LED lamp, xenon lamp power is only 100 watts or.

This year, the first section of the city's street lights tried to use the LED lights, hernia lights. "Li Dong said, urban road street, North Waihuanlu dawn are xenon lamp, LED lamp, from the use, the high-pressure sodium lamp 100 watt xenon lamp can replace 250 Watt xenon lamp, high-pressure sodium lamp can replace 150 watts 400 watts; and the LED lamp is not bright and dim illumination brightness etc. unstable situation. Based on the LED lamp product performance is not stable, and the investment cost is huge, temporarily not considered as street lamp. "If xenon lamp can achieve high light efficiency, long life and other characteristics, we will consider further promotion. Li Dong said that the use of energy-saving lamps in the street, they need to continue to explore.

Let the lamp power saving, in addition to try new lamps, bright street company also tried a new way of using. For example, in the street every Chengshan Avenue was originally installed 3 250 Watt light bulbs, comprehensive transformation in Chengshan road this year, after every new street only installed 2 250 Watt light bulb. Li Dong said, "don't look at the bulb less than the original one, because the lamp is reasonable to choose according to the actual situation of the road, its design is more scientific, but also the high wattage brightness change, not only after the new Chengshan Avenue street than the original light, but also save electricity, reduce power consumption.

Install remote monitoring street lamp "look at the sky" switch

Street light energy consumption, operating mode is another important factor. In order to reduce the operating costs of street lamps, Rongcheng street lamp energy-saving monitoring system, so that the street lamp to achieve a "look at the day" switch, effectively reducing the working hours of street lamps.

2011 years ago, the city's street lighting system is mainly controlled by time, the implementation of the point to turn on the lights, turn off the lights, the workflow, it is too rigid defects, can not be automatically changed depending on the weather conditions. In the evening, the sky is not dark, street lights on; in the morning, the sky has been bright, street lights are still stick to the post, a waste of electricity. After the use of street lamp energy saving monitoring system, the situation of waste energy is effectively controlled. "Street lights' look at the day 'switch, the daily lighting and turn off the lights are not the same time. 2 am, in the city Housing Authority bright street company monitoring room, Li Dong showed the city's street lights turn off schedule, a year of 365 days, almost every day is not the same. Li Dong said, the specific time switch lights in Rongcheng based on the latitude and longitude, time of sunrise and sunset to measure the judgment, it was summer night, bright street early, opening and closing time will fall, and winter is not the same, it is also more scientific and reasonable energy saving.

The street lamp energy saving monitoring system under special weather conditions or temporary lighting, without laborious to staff to the scene by road open street, only need to adjust the monitoring system through the computer, you can achieve the switch or extend the lamp lighting time, convenient emergency road lighting scheduling.

Try out the light of the Lantern Festival

In order to maximize energy savings, bright lights in the company also tried Road 9 at night after lights, lights and other halfway across the various forms of energy saving. "The reason for the implementation of such a measure is to consider the distance between the opening of a street lamp does not affect the brightness of the road to meet the needs of road lighting. "Li Dong said, the town and surrounding villages and towns and the urban road connections to 9 in the evening after the pedestrians and vehicles less, street light can also meet the lighting requirements, in view of this situation, the town and surrounding towns and connecting the urban road lamps adopted before 9 in the evening 9 pm to all bright after the bright way. Currently, with the Sea west road, West Ring Road and other surrounding towns and urban roads connected with the use of such lighting. Li East roughly calculated, according to the way the lights off, only the West Outer Ring Road and sea can save electricity more than 360 thousand degrees a year, saving street electricity tariff of $about 300000.

Through a variety of measures to reduce energy consumption, the energy efficiency of Rongcheng street lamp has been relatively significant. "Li Dong said that in 2010, Rongcheng street lamps throughout the year
