路(lu)燈間隔(ge)也就路(lu)燈間距,是由路(lu)燈的(de)照明功率、路(lu)燈高度(du)、馬(ma)路(lu)寬度(du)等多種因素共同決(jue)定(ding)。路(lu)燈間距一(yi)般是燈桿高度(du)的(de)3.8-4倍。路(lu)燈燈具的(de)縱向間距一(yi)般為30米~50米,當有電(dian)(dian)(dian)力線桿或其它電(dian)(dian)(dian)桿時,間距為40米~50米。盡量(liang)將供電(dian)(dian)(dian)電(dian)(dian)(dian)桿與(yu)照明電(dian)(dian)(dian)桿合桿,以(yi)節約投資,如果采(cai)用地下(xia)電(dian)(dian)(dian)纜供電(dian)(dian)(dian),間距宜小,有利于照度(du)的(de)均勻度(du),間距通常為30米~40米。
