LED street lamps are mixed in foreign countries

[Lighting Network] After Tempe, Arizona, determined that LED lights were not suitable for the extreme desert climate in the region, American Lighting Technology Co. , Ltd. announced that it would provide 1000 induction street lamps to the city. Tempe, Arizona, is embarking on a block lighting system renovation project and has chosen induction lamps instead of LED-based solid-state lights (SSL)To replace the high pressure sodium lamp (HPS)And metal halide lamps (MH). U. S. lighting technology company announced that it will provide 1000 induction lamps to the city to save energy, saving up to of energy consumption. Obviously, Tempe City believes that LED lights are not suitable for the extreme desert climate in the southwest of the region. AlexanderHam, executive vice president of American lighting technology company, said: After evaluating and comparing the two main street lighting lamps, induction street lamp and LED lamp, considering the expensive equipment cost of LED lamps and the unstable performance in extreme weather in southern Arizona, Tempe City chose to give up LED lamps. Of course, other cities and public facilities choose induction lamps instead of LED-based solid-state lamps, mainly due to the low cost of induction lamps in the early stage. Whether the factors hindering the development of LED are climatic factors is still a question. As we all know, lamps and lanterns must be designed to conduct heat efficiently in a reliable manner. However, compared with the low temperature nights in the southwestern desert, LED lights are more reliable in high temperature areas. Of course, inductive lighting technology can indeed save energy consumption than traditional technology. U. S. Lighting Technology Co. , Ltd. will provide 70W Cobra100 series lamps to Tempe City to replace 125W high pressure sodium lamps or metal halide lamps. Induction lamps do not have the capability of fine-grained dimming, while LED lamps can further reduce energy consumption through adaptive control. Poor LED experience in Columbus, Ohio, in general, LED street lamps usually receive rave reviews in addition to excessive upfront costs. However, Columbus, Ohio, is an exception to a report on LED street lamp testing by TheColumbusDispatch. The newspaper said that some LED energy-saving lamps did not pass the test within two months after installation. Dublin, also in Ohio, has allocated US $500 thousand and will use LED technology to renovate 1500 street lamps. Dublin's test results show that the use of LED lights can reduce energy consumption by 40 to 50. LED street lamps and space lighting in Iowa and Mississippi are being continuously promoted in most parts of the United States. TheDesMoinesRegister reported that Iowa city is installing an LED-based lighting system in ValleyJunction Park, and the city will complete the installation of LED lights this fall to save 50 lighting energy. In addition, the city will use this as a pilot project for the renovation of the lighting system of the entire ValleyJunction Park. Rankin County in Mississippi has installed solar-powered LED street lamps, and the solar lighting Alliance has also released guidance documents.
