style="text-indent:25px">我國的道路燈具，基本都采用HID光源加配觸發(fā)器和電感鎮(zhèn)流器的模式，這一模式雖說存在能效較低及頻閃的問題。而采用電子驅(qū)動(dòng)電路的LED燈具，在野外照明場(chǎng)合使用時(shí)，威脅其可塑性的一個(gè)重要方面是雷電感應(yīng)問題。眾所周知，空中的閃電發(fā)射的是一廣譜的無線電波，而架空的道路燈具供電線路，是良好的接受無線。兩根電源線接收的同一閃電發(fā)出的無線電波，對(duì)驅(qū)動(dòng)電路來講是屬于共模干擾信號(hào)，這種共模干擾對(duì)地可達(dá)數(shù)佰伏到數(shù)千伏，很容易擊穿驅(qū)動(dòng)電路內(nèi)的EMC接地電容或較小的對(duì)地（對(duì)外殼）的電氣間隙，造成驅(qū)動(dòng)電路的損壞。另外由于我國的供電線路是三相四線制中性線接地的極性電源，所以在兩根架空供電線的各段，在感應(yīng)到閃電的無線電波的瞬間，由于兩根供電線對(duì)地的瞬時(shí)阻抗不同而使兩根供電線間產(chǎn)生一個(gè)差模的干擾電壓，這一瞬時(shí)差模干擾電壓也可達(dá)到數(shù)百伏至3000多伏，這一電壓往往會(huì)擊穿驅(qū)動(dòng)電路的電源整流二極管和印制線路板上的不同極性電極間的電氣間隙，LED控制器同樣會(huì)使驅(qū)動(dòng)電路損壞。</p><p style="text-indent:25px">照明用LED的比較大特點(diǎn)是具有定向發(fā)射光的功能，因?yàn)楣β市蚅ED幾乎都裝有反射器，并且這種反射器的效率都明顯高于燈具的反射器效率。另外，LED的光效檢測(cè)時(shí)已經(jīng)包括了自身反射器的效率。采用LED的道路燈具應(yīng)盡可能地利用LED的定向發(fā)射光的特性，使道路燈具中的各個(gè)LED分別直接把光線射向被照路面的各個(gè)區(qū)域，再利用燈具反射器的輔助配光，來實(shí)現(xiàn)很合理的道路燈具的綜合配光。應(yīng)該說，道路燈具要真正做到符合CJJ45-2006和CIE31以及CIE115標(biāo)準(zhǔn)的照度和照度均勻度要求，燈具內(nèi)應(yīng)包含三次配光的功能才能比較好地實(shí)現(xiàn)。，而帶反射器的并且具有合理的光束輸出角度的LED本身就具有良好的一次配光功能。在燈具內(nèi)，能按照路燈具高度及路面寬度設(shè)計(jì)各個(gè)LED的安裝位置和發(fā)射光的方向就能實(shí)現(xiàn)良好的二次配光功能。在此類燈具中的反射器，只作為輔助的三次配光手段，來保證道路照度更好的均勻度。</p><div

style="text-indent:25px">LED路燈的光色問題。大功率LED路燈，作為道路照明光源，在視覺感覺上過分陰冷甚至陰森，不利于機(jī)動(dòng)車駕駛。LED路燈的壽命不高。高壓鈉燈平均壽命4年。LED路燈的使用壽命暫無實(shí)用經(jīng)驗(yàn)，現(xiàn)有的企業(yè)號(hào)稱5萬小時(shí)，尚無可靠依據(jù)。因?yàn)長(zhǎng)ED驅(qū)動(dòng)電路裝置的電容器壽命，只有1萬小時(shí)左右。大功率LED路燈基本上是采用5000K 左右所在色溫的白光。作為道路照明光源，視覺感過分陰冷，同時(shí)遠(yuǎn)視時(shí)觀察能力會(huì)下降，在這方面路燈使用單位相當(dāng)有發(fā)言權(quán)，3000K左右的黃光或暖白光是比較適合道路照明的，因此日光色的LED路燈不適合做路燈使用。 LED路燈在產(chǎn)品規(guī)格方面缺少統(tǒng)一的技術(shù)標(biāo)準(zhǔn)，還沒有統(tǒng)一的LED路燈生產(chǎn)技術(shù)標(biāo)準(zhǔn)，每個(gè)廠家按自己的標(biāo)準(zhǔn)生產(chǎn)自己的產(chǎn)品，彼此間是很難通用的，另外LED路燈生產(chǎn)廠家的燈具自成體系，光源電器組裝和燈具捆綁在一起，各自不同的工作特性難以維護(hù)，維護(hù)時(shí)必須使用原廠產(chǎn)品。江蘇LED路燈報(bào)價(jià)</p><p
