In March 2010, licheng district open source road 2.9 km street lamps, all by high pressure sodium lamp replacement for super bright LED low carbon environmental protection lamps.We should become jinan first all roads LED lighting demonstration way.In 2013, jinan erhuanxi road nearly 13 km thousands of street lamp by high pressure sodium lamp replacement for LED lights.This is jinan one of the few sections using LED lighting.The reporter understands from the street lamp construction stakeholders, only 13 kilometers of LED street light, can save 7 million KWH for five years.
LED lamp compared with the traditional energy-saving lamps or high pressure sodium lamp advantage in where?Related research institutions public data shows that LED lights line of high quality, no radiation, reliable, durable, maintenance cost is very low.Its use time is relatively long, in general, leds can be used more than 50000 hours, more than half of it better than the traditional energy-saving lamps and energy saving.In addition, the LED lamp is the most prominent advantage or on environmental protection, for example, every 48 – watt LED lights to replace the traditional high pressure sodium lamp 150 w lamp can reduce carbon dioxide emissions a year is about 1.8 tons.
Nevertheless, now in Jinan except for a few open road 2.9 km section of road Licheng District, 13 km section of the Second Ring Road, Jinan, etc., the Jinan City, the road has not been widely available lights LED. A related practitioners to reporters calculations, “In the current mainstream kind of city street lights are being used – high pressure sodium Case estimated its maintenance costs, every street lamp maintenance costs about 300 yuan, the city’s total of 160 000 street, five years down the maintenance costs probably more than 10 million. “In both the more obvious advantages of the poor conditions, in spite of relatively inexpensive LED maintenance and environmentally friendly, but did not with its own advantages among the mainstream market in Jinan.
And the extent of the current popularity of LED lights in the Jinan market, as the number of local LED enterprises and innovation capacity lags. An official in charge of the energy industry in Jinan unit has issued emotion: “In Jinan promotion of LED lights, can cite the brand most local companies are from the South can not do large orders, small orders not want to do..” Turning to the reasons, The practitioners Poxian frustration: “departmental interests involved, the official threshold is high, private entrance.”
Compared with European and American countries relatively developed LED industry, the domestic application of LED lighting products more difficult.Statistics show that in our country, the LED energy-saving lamps such as penetration rate is still low, incandescent lamp sales is about 2 billion per annum at present, the use of small and medium-sized city residents incandescent proportion generally above 30%.
