1.光衰小，一年的光衰不到3%，使用10年仍達(dá)到道路要求，而高壓鈉燈光衰大，一年左右已經(jīng)下降30%以上，因此，LED路燈在使用功率的設(shè)計(jì)上可以比高壓鈉燈低。 LED路燈有自動(dòng)控制節(jié)能裝置，能實(shí)現(xiàn)于滿足不同時(shí)段照明要求情況下比較大可能的降低功率 2. 節(jié)省電能?？蓪?shí)現(xiàn)電腦調(diào)光，分時(shí)間段控制，光線控制，溫度控制，自動(dòng)巡檢等人性化功能。 3. 壽命長：能使用5萬小時(shí)以上，提供三年的質(zhì)量保證。不足之處就是電源的壽命得不到保證。 4.光效高：采用≥100LM以上的芯片，相對(duì)于傳統(tǒng)高壓鈉燈能節(jié)能75%以上。 5.安裝簡(jiǎn)便：無需加埋電纜無需整流器等，直接將安裝于燈桿接上或者將光源嵌套原有燈殼。 6.散熱控制出色：夏天溫度控制在45度以下，并采用被動(dòng)散熱方式，夏天的散熱保障不足。 7.質(zhì)量可靠：電路電源全部采用高質(zhì)量元器件，每顆LED都有單獨(dú)過流保護(hù)，無需擔(dān)心損壞。 8. 光色均勻：不加透鏡，不以提高亮度而**均勻光色，從而保證無光圈光色均勻。 9. LED不含有害金屬汞，在報(bào)廢時(shí)不會(huì)對(duì)環(huán)境造成危害。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇LED路燈廠家定制"

style="text-indent:25px">LED路燈散熱技術(shù)，一般使用多為導(dǎo)熱板方式，是一片5mm厚的銅板，實(shí)際上算是均溫板，把熱源均溫掉；也有加裝散熱片來散熱，但是重量太大。重量在路燈系統(tǒng)上十分重要，因?yàn)槁窡舾哂?米，若太重危險(xiǎn)性就增加，尤其遇到臺(tái)風(fēng)、地震都可能產(chǎn)生意外.國內(nèi)有廠家采用全球**的針狀散熱技術(shù)，針狀散熱器的散熱效率要比傳統(tǒng)片狀散熱器有很大幅度提高，能使LED結(jié)溫比普通散熱器低15℃以上，并且防水性能比普通鋁型材散熱器要好，同時(shí)在重量和體積上也有所改進(jìn)。另外，針對(duì)大功率LED燈具開發(fā)的石墨散熱片也具有良好的導(dǎo)熱和散熱性能。散熱方式主要有：自然對(duì)流散熱、加裝風(fēng)扇強(qiáng)制散熱、熱管和回路熱管散熱等。加裝風(fēng)扇強(qiáng)制散熱方式系統(tǒng)復(fù)雜、可靠性低，熱管和回路熱管散熱方式成本高。而路燈具有戶外夜間使用、散熱面位于側(cè)上面以及體型受限制較小等有利于空氣自然對(duì)流散熱的優(yōu)點(diǎn)，所以LED路燈建議盡可能選擇自然對(duì)流散熱方式。</p></p><br
