Wuhan: Scenic Street into the Han 4 years is difficult to see"

At the end of April 2009, the new street lamp 26 head shoulder windmills, solar panels in Hankou beach area debut, became a unique landscape. Subsequently, along the River Road, Hongshan Plaza, both sides of the aisle, East Lake South Road and other places have also been installed by the wind or solar power generation of new energy streetlights. But 4 years later, these environmentally friendly street lamp has been frequently complaints. Some people said that now walk along the River Road, these new energy or light brightness is not enough, or simply do not light, can not play the role of lighting. Why not use these lamps to spend a lot of money? Recently, the reporter interviewed on this issue-

Visit many scenic street lights are not too bright

At the end of April 2009, the emergence of new energy many street chic style Hankou Yanjiang Avenue near Huangpu Road, Hankou Road on the beach. As long as there is a wind or solar radiation can generate electricity, to the night can be stored in the power to automatically light street lights. This kind of lamp is called "scenery complementary street lamp". However, some people complain that these street lights are not bright enough, some lights are not even lit. "If it is not a street lamp lighting other, rely on these new energy lamps must not bright enough. "Last night at about 8, reporters came to Hankou, Ms. sun in here to jump square dance, she almost every night to the beach, these beautiful lights basically do not play the role of lighting. Reporter walked in a circle and found in the marshland, though still on the rotation of the windmill blades lights, 26 lights in 5 but the lamp is not lit, the lights are still on the job can only illuminate the street just below the ground, in contrast to other river street high brightness is very inconspicuous.

Hongshan square next to the north side of the passage of solar street lamps have similar embarrassment. At 9:30 last night, the reporter saw at the scene, both sides of the solar street lamp issued a small group of white light. Careful number, 40 solar street lights in the 11 did not light. For a week, the reporter observed in Hongshan square, where there are nearly 1/3 solar street lights do not shine every day.

Solar street lamp case Zhuodaoquan near East Lake south road is similar. Mr. Xu, who lives nearby, said solar street lamp brightness is too low, in the past did not note that there is a row of street lamps in the lighting.

Doubts

Three factors affect the lighting effect

It is understood that the cost of new energy street lamps is much higher than ordinary street lamps, why these high prices of lights look good? Insiders said that the main reason is that the relevant technology is not mature enough.

Along the road of "complementary scenery construction - Street" project zklingyun New Energy Company deputy general manager Li Sheng introduced to the road along the river "scenery complementary lamps" as an example, in the current level of technology, can withstand the conditions in the budget, fan and solar panels to convert electrical energy can only take up 80 watts around the street, but six lane two-way lamp power of 200 watts or more basic ordinary, natural brightness difference. In addition, the new energy street lamp dependence on natural resources is high. The wind and solar energy resources in Wuhan is very general, the same level of energy conversion chips, in Tianjin can do 150 watts of street lights, and Wuhan can only take a move of 80 watts. "

People feel that the new energy street lights are not bright, there is a factor because these streetlights are mostly cold light source. Whether it is scenery complementary street lamp, solar street lamp or LED street lamp, is a white light, this light makes people feel nervous; and orange warm light source makes people feel comfortable and comfortable, people prefer to be more accustomed to. Li Sheng said, cold light source also allows the public to judge the brightness of a little error.

The lamp is not bright enough for the public to reflect the situation, Wuhan City Street Management Bureau staff said, through the observation of the pilot found that new energy lamp can basically meet the lighting requirements in the two lane road, the main road illumination requirements higher, only used as a supplement. If the public found that the lights do not light can call the hotline repair hotline. They will also be regular inspections, timely repair.

20 thousand yuan of "high light" There are both advantages and disadvantages.

From the cost of street lamps, the new energy is indeed much higher than the traditional street lamps. Li Sheng introduction, 4 years ago, a set of 80 watts of scenery complementary streetlights need about $26 thousand, in recent years due to the more mature design specifications, construction costs and prices declined slightly, but still requires nearly $20 thousand. However, the same power of traditional street lamps, the cost of 5000 yuan.

In addition, so street management is a headache: the maintenance cost of the new energy street later than ordinary street lamps, the core components of the batteries used lead-acid batteries, only experienced 800 times of charge and discharge, which means the battery every 3 to 5 years will need to be replaced once, otherwise it will affect the brightness of the lamp. Spend thousands of yuan to replace the. In order to ensure the new solar panels and wind power generator energy street branch block, street management departments need to conduct regular inspections and timely pruning, but the trees and lamp belonging to different departments, need more communication and cooperation.

However, this new energy street lamp has many advantages. Li Sheng believes that the lamp cost comprehensive calculation, installation requires the laying of cables, the traditional street around a complete power supply facilities, "if the installation of the transformer, and the electricity cost of road digging embedding into account, new energy cost is not higher than the traditional street lamp. Li Sheng said that the popularity of the network is not high in remote areas, Riverside riverside scenic areas, street lamps
