led發光地磚燈有(you)鋁，鋁合金，鐵，ABS，塑料(liao)，丙(bing)烯酸，玻(bo)璃等，一般來說(shuo)鋁是好點(dian)。

LED球(qiu)泡燈的(de)(de)鋁基板(ban)(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)一種(zhong)具有良好(hao)散熱(re)功能(neng)的(de)(de)金(jin)屬基覆銅(tong)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。通(tong)常，單個面板(ban)(ban)(ban)(ban)(ban)(ban)(ban)由三層(ceng)組成，即電路(lu)(lu)層(ceng)（銅(tong)箔(bo)），絕(jue)緣(yuan)層(ceng)和金(jin)屬基底層(ceng)。還設計(ji)用(yong)(yong)于高端用(yong)(yong)途的(de)(de)是(shi)(shi)雙層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，其結構(gou)是(shi)(shi)電路(lu)(lu)層(ceng)，絕(jue)緣(yuan)層(ceng)，鋁基，絕(jue)緣(yuan)層(ceng)，電路(lu)(lu)層(ceng)。對于多層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)應(ying)用(yong)(yong)很少，可以由普通(tong)的(de)(de)多層(ceng)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)與絕(jue)緣(yuan)層(ceng)，鋁基粘接(jie)而成。 LED鋁基板(ban)(ban)(ban)(ban)(ban)(ban)(ban)是(shi)(shi)PCB，也(ye)是(shi)(shi)印刷電路(lu)(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)意思，只是(shi)(shi)電路(lu)(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)材料(liao)是(shi)(shi)鋁合金(jin)，之前一般電路(lu)(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)材料(liao)是(shi)(shi)玻(bo)璃纖維，但(dan)由于LED發熱(re)較(jiao)大(da)，所以LED的(de)(de)電路(lu)(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)燈具一般是(shi)(shi)鋁基板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，導(dao)熱(re)性很快，其他設備(bei)還是(shi)(shi)電路(lu)(lu)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)或玻(bo)璃纖維板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。

物料(liao)不合(he)格：從近(jin)年來情況(kuang)處理的(de)故障情況(kuang)來看，物料(liao)質(zhi)量低也有很大的(de)因素。主要性(xing)能是(shi)：鋁線少，線比較(jiao)硬，絕緣層(ceng)薄。這是(shi)更常見(jian)的(de)。

配套項(xiang)目質量不好：草坪燈電(dian)纜(lan)通常鋪設在綠化(hua)帶上。路面(mian)(mian)施工(gong)質量差(cha)，地面(mian)(mian)沉降，電(dian)纜(lan)應力變形，造成電(dian)纜(lan)鎧裝。特別(bie)是，中國東北位于高山地帶。冬天來了，電(dian)纜(lan)和土(tu)壤(rang)形成了一個整體。一旦地面(mian)(mian)沉降發生，它將被拉到草坪燈基(ji)礎(chu)的(de)底(di)部。

不(bu)(bu)合理的(de)(de)設計：一方面是過載(zai)運行。隨(sui)著城(cheng)市(shi)建(jian)設的(de)(de)不(bu)(bu)斷發(fa)展，草(cao)坪(ping)(ping)燈(deng)(deng)(deng)也不(bu)(bu)斷延伸(shen)，新(xin)草(cao)坪(ping)(ping)燈(deng)(deng)(deng)經常在附近接(jie)到電路的(de)(de)草(cao)坪(ping)(ping)燈(deng)(deng)(deng)附近，再加上廣(guang)告(gao)業務的(de)(de)發(fa)展很(hen)快，中山路燈(deng)(deng)(deng)的(de)(de)廣(guang)告(gao)負荷也相應增加了，草(cao)坪(ping)(ping)燈(deng)(deng)(deng)負載(zai)過大，電纜(lan)線鼻過熱(re)，發(fa)熱(re)，絕緣，接(jie)地短路等(deng)；

另一方面是，只有在(zai)設計(ji)燈柱時才考(kao)慮燈柱的自(zi)身情(qing)況，忽略電纜(lan)頭的空間(jian)，將電纜(lan)頭包(bao)(bao)包(bao)(bao)裹后，多數是沒有將門全部(bu)關上，有時電纜(lan)長度不(bu)足，接頭使不(bu)符(fu)合(he)要求(qiu)，這(zhe)也是造成麻煩(fan)的因素。
