Hefei Evening News After the completion of the renovation of the Lianhua Road in the Economic and Technological Development Zone, this year's National Day was opened to traffic. The spacious pavement made it easy for Mr. Zhang Lao, who lives in the Lotus Community, to look at the street lights that shine every night. Zhang Some old embarrassed, "How much electricity does it cost to spend such a night?" The reporter learned that the application of this new LED light source not only has good brightness, but also saves electricity every year compared with the previous high-pressure sodium lamp. Ten thousand degrees.
LED street light drives away "black night"
The reporter saw it on Lianhua Road last night. It is different from the slightly dim orange street lights in many streets in the city. The lights here are white and bright. Under the street lights of a row of four columns and one column, the white line of the traffic sign on the dark asphalt road is clearly visible. According to the person in charge of the relevant departments of the Management Committee, Lianhua Road is an important north-south traffic trunk road in the Economic Development Zone. After the renovation, LED street lights are used as road light sources. It is understood that LED is what we usually call LEDs. The remarkable features are high photoelectric conversion efficiency, high color saturation, low voltage power supply, safety for human body and long life.
One road saves 760,000 degrees a year
The new LED light source, known as the "third generation lighting revolution", is significantly more energy efficient than traditional high pressure sodium lamps. Based on the current implementation section of Lianhua Road (Note: the total length of the road is 6 kilometers, part of the renovation) is 3.85 kilometers. The original design of a column of street lamps is 900 watts, of which 650 watts of main road and 250 watts of auxiliary roads. Only one column lamp 312 watts, that is, the main channel 240 watts, the auxiliary channel 72 watts can be replaced to achieve the original design illuminance requirements. "A total of 220 pillars of street lamps, 880 ç›, 12 crossing lights, 72 ç› are installed." Song Xuehong, deputy director of the Development and Development Bureau of the Economic Development Zone, said, "We installed two new electric meters for actual measurement before installation, and the results were calculated. Compared with high-pressure sodium lamps, LED street lamps can save 763,474 degrees a year."
Can street lights be completely replaced with LEDs?
It is understood that Lianhua Road is currently the first city in Anhui Province to use LED street lights on the main roads of the city. Why is this new energy light that is bright, energy-saving, and long-lived not used in large areas? “The cost of one-time investment is high, and there is no unified LED lighting standard in the country.†Song Xuehong told reporters that according to the original high-pressure sodium lamp, the purchase of the lamp in the lotus section needs about 1.8 million yuan. “The LED lamp is at least two or three times more. "Because there is no unified LED lighting standard in the country, the chips, heat dissipation technology, optical system and power supply used by various domestic manufacturers are different, and the lamps are mixed, and the price difference is also very large.
In order to reduce the one-time investment, the LED lights of Lianhua Road were finally installed in cooperation with a company in the area. “They provide the lamps for free. We will return some of the annual savings during the cooperation period to the manufacturer. If the lamps are damaged or damaged during the cooperation period, the manufacturer is responsible for the replacement and maintenance.†(Wang Jin)
