JNHX-E-50型電源指示燈外殼用(yong)(yong)冷軋板(ban)加工(gong)而(er)成，表面(mian)采用(yong)(yong)靜(jing)電噴塑外表光滑明亮，具有耐(nai)腐蝕壽命(ming)長等特點(dian)。發(fa)光體(ti)采用(yong)(yong)直徑50MM的線路板(ban)，上面(mian)用(yong)(yong)10個(ge)(ge)直徑10MM的高亮度發(fa)光二管(guan)并聯而(er)成，可以(yi)保(bao)證在單個(ge)(ge)管(guan)發(fa)生故障時不影響(xiang)整體(ti)正常發(fa)光， 單個(ge)(ge)亮度可以(yi)達到8仟到兩萬(wan)MCD（普通管(guan)為1000-3000）。

電(dian)(dian)(dian)路(lu)設(she)(she)計(ji)采用(yong)恒壓(ya)恒流(liu)設(she)(she)計(ji)，保證發光管的壽命為100000小時，電(dian)(dian)(dian)源變壓(ya)器設(she)(she)計(ji)在考慮(lv)到工廠(chang)電(dian)(dian)(dian)壓(ya)波動大(da)(da)(da)，電(dian)(dian)(dian)網干擾(rao)多而采用(yong)特(te)制變壓(ya)器，可減(jian)少(shao)電(dian)(dian)(dian)網對信號燈的沖(chong)擊大(da)(da)(da)大(da)(da)(da)的提高了(le)燈具的使用(yong)壽命。
