Selecting LEDs for Streetlights

　　用于路燈LED市場最近撞了一下，因為奧巴馬總統的全國路燈升級計劃在近期宣布美國市長會議。先進的戶外lighting1總統的挑戰下，總統呼吁地方城市升級150萬路燈。這樣做，根據美國能源部，地方政府可以減少百分之50或更多的戶外照明法案。

　　好消息是，LED路燈的價格已經下降到足夠的回報期越來越有吸引力的城市。一般來說，LED的成本占整個系統的百分比是在百分之50范圍內幾年前，根據LED制造商。今天，LED作為系統成本的百分比約為20至百分之25。這意味著路燈燈具的制造商正在尋找在他們的系統中的其它元素–光學、散熱片和組件–作為成本動因。

　　In addition to cost， one of the top specifications that any streetlight designer has to consider when selecting LED components is efficacy and meeting more stringent lighting standards. This should be coupled with LED platforms that offer a wide range of CRIs and CCTs in order to meet the exact requirements for the streetlight application. Other top characteristics include quality and reliability to ensure longer lifetimes and lower maintenance costs.

　　For even more energy savings， these streetlights can be coupled with dimmable control systems. An extra benefit is a reduction in light pollution. In addition to the savings in energy consumption， the LED streetlights also provide better nighttime visibility and can provide a more “comforting” light for pedestrians.
