Selecting LEDs for Streetlights

　　Selecting LEDs for Streetlights

　　用于路燈LED市場(chǎng)最近撞了一下，因?yàn)閵W巴馬總統(tǒng)的全國(guó)路燈升級(jí)計(jì)劃在近期宣布美國(guó)市長(zhǎng)會(huì)議。先進(jìn)的戶外lighting1總統(tǒng)的挑戰(zhàn)下，總統(tǒng)呼吁地方城市升級(jí)150萬路燈。這樣做，根據(jù)美國(guó)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(jià)格已經(jīng)下降到足夠的回報(bào)期越來越有吸引力的城市。一般來說，LED的成本占整個(gè)系統(tǒng)的百分比是在百分之50范圍內(nèi)幾年前，根據(jù)LED制造商。今天，LED作為系統(tǒng)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(tǒng)中的其它元素–光學(xué)、散熱片和組件–作為成本動(dòng)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.
