Wafangdian City: 70 thousand LED street lights annual electricity tariff of 5 million

Following the closure of all powerful pollution type cement kiln and heating chimney, a small paper mill, prohibition of building solid clay brick and all residents with gas natural gas, Wafangdian City City, the work of energy-saving emission reduction and big moves: investment of about 37000000 yuan, the 70 thousand city light to the high-pressure sodium lamp as light source lamps and landscape lighting to replace all LED energy-saving lamp, thus becoming the first to achieve LED street lighting city. The new lamp and landscape lamp service life of 13.5 years - more than 15 years, energy saving of more than 70%, only electricity, an annual savings of $about 5000000.

The full name of LED semiconductor LED street lamp road lighting source, the service life can reach 50 thousand hours, is 13 to 15 times of the traditional high pressure sodium lamp, the maintenance cost is greatly reduced; LED lamp can also work voltage of 24 volts, not only the working voltage and safety, construction safety; the most important is the energy saving, according to work 10 hours a day one day, LED lights can be more than the traditional high-pressure sodium lamp 70%, a LED landscape lamp can save more than 80%, 70 thousand lights and at least a year can save electricity about 5000000 yuan. Due to low power consumption, low voltage, can also save the cable 75%. In the realization of energy saving at the same time, LED street lamp and achieve efficient lighting, its color rendering index of 80% or more, far higher than the traditional high pressure sodium lamp of 26%. LED street can effectively control the distribution of light, make the light into a light strip along the direction of the road lamp when spreading, reaching a height of 12 meters, light range can be more than 50 meters, greatly improves the traffic safety, do not interfere with the effective lighting, households, effectively reduce light pollution; LED the heat emitted by the lamp is only higher than the ambient temperature of 15 DEG C, far less than the traditional sodium lamp at 300 DEG C, and greatly reduce the heat emission at the same time, unlike the traditional sodium lamp LED lamps that contain mercury and argon and other harmful gases, known as the "green lighting".

Last year, Wafangdian City City, the successful introduction of Dalian nineo-nine Co. ltd.. The company invested more than 400 million yuan to carry out research and development of LED lighting equipment, so that Wafangdian City has become one of the few large LED R & D and production base in china. In support of the Wafangdian City municipal government, nineo-nine successfully participated in the 4 national LED lighting standards drafting. It is understood that after the realization of urban road street in Wafangdian City LED lighting, will continue to expand the scope of application of LED. Not only the new residential courtyard, underground garage, etc. will be gradually introduced LED lighting, five out of the mouth of the street will also be included in the planning.
