冲孔发光字（http://www.fgzgc.com/）又叫外露发光字，其制造材料是根据现场实际可分多种，如铝板、锌铁、不锈钢；材料不同层次不一样，安装的难易程度也不一样。冲孔发光字能够做成较大的发光字，一般写字楼、住宅楼等超高层建筑都选用冲孔发光字。下边笔者给我们介绍的是冲孔发光字的发光原理，以及冲孔字光源的特色。

normal style='FONT-SIZE: 12px; FONT-FAMILY: "sans serif", tahoma, verdana, helvetica; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(102,102,102); FONT-STYLE: normal; MARGIN: 5px 0px; ORPHANS: 2; WIDOWS: 2; LETTER-SPACING: normal; TEXT-INDENT: 0px; overflow-wrap: break-word; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial' font-size:14px;?="">1、电压：运用低电压电源，供电电压在2~4V之间，根据产品不同而异，所以它是一个比运用高压电源；更安全的电源，特别适用于公共场所；

normal style='FONT-SIZE: 12px; FONT-FAMILY: "sans serif", tahoma, verdana, helvetica; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(102,102,102); FONT-STYLE: normal; MARGIN: 5px 0px; ORPHANS: 2; WIDOWS: 2; LETTER-SPACING: normal; TEXT-INDENT: 0px; overflow-wrap: break-word; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial' font-size:14px;?="">2、电流：作业电流在0~15mA，亮度随电流的增大而增亮；

normal style='FONT-SIZE: 12px; FONT-FAMILY: "sans serif", tahoma, verdana, helvetica; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(102,102,102); FONT-STYLE: normal; MARGIN: 5px 0px; ORPHANS: 2; WIDOWS: 2; LETTER-SPACING: normal; TEXT-INDENT: 0px; overflow-wrap: break-word; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial' font-size:14px;?="">3、效能：消耗能量较同光效的白炽灯减少80%；

normal style='FONT-SIZE: 12px; FONT-FAMILY: "sans serif", tahoma, verdana, helvetica; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(102,102,102); FONT-STYLE: normal; MARGIN: 5px 0px; ORPHANS: 2; WIDOWS: 2; LETTER-SPACING: normal; TEXT-INDENT: 0px; overflow-wrap: break-word; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial' font-size:14px;?="">4、适用性高：很小，每个单元LED小片是3~5mm的正方形，所以能够制备成各种类型灯珠形状的器材，而且适合于易变的环境。
