Selecting LEDs for Streetlights

　　Selecting LEDs for Streetlights

　　用于路灯LED市场最近撞了一下，因为奥巴马总统的全国路灯升级计划在近期宣布美国市长会议。先进的户外lighting1总统的挑战下，总统呼吁地方城市升级150万路灯。这样做，根据美国能源部，地方政府可以减少百分之50或更多的户外照明法案。

　　好消息是，LED路灯的价格已经下降到足够的回报期越来越有吸引力的城市。一般来说，LED的成本占整个系统的百分比是在百分之50范围内几年前，根据LED制造商。今天，LED作为系统成本的百分比约为20至百分之25。这意味着路灯灯具的制造商正在寻找在他们的系统中的其它元素–光学、散热片和组件–作为成本动因。

　　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.
