针对PCB板材的材质来分析,PCB板也有分很多种质量层次,市面上大部份廉价的线条灯选用的是二次料的PCB板材,这种板材在受热后容易分层、铜箔太薄容易掉、粘合性不好铜箔层和PCB板层容易分开,更不用说线路稳定性如何,板材都这样还指望线路是稳定的吗?别开玩笑了,大家都很忙!大多数便宜的线条灯它没有经过合理的线路布局和检验测试去测评它的可靠性和稳定性。而正规的led线条灯厂家所生产出来的产品肯定会做到这一点才能在市面上销售。
1、看灯具上的标签,一般正规的线条灯厂家都会在灯具出厂前贴上标签示意该产品的具体参数,我们可以通过标签去看该线条灯所使用的电压是多少伏。
2、没有标签的情况下怎么做?在灯具上没有标签标明电压是多少,如果灯具上是透明胶水,可清楚的看到灯体内部的元器件时,可通过它的灯珠数量、电阻、电容等元器件进行判断,然后从低往高的电压去测试该灯具的亮灯情况,期间可选用一些测电工具辅助测试。如果在外观无法看清楚灯体内部元器件时,就需要拆开灯具进行检测。
