标题: 请教测温升时的电压问题 [打印本页] 作者: leishw 时间: 2018-10-18 17:59 标题: 请教测温升时的电压问题 各位好，在此请教一下灯具测温升时的工作电压标准？如额定工作电压是AC220V，我在做温升测试时点灯时的电压是按220V还是要220*1.1＝242V.还是其他电压，我们的代理是按220*1.1*1.06＝256V来测试的。这应该是家电标准吧，灯具没有找到这样的说法。 3 O9 a, f% ~" R& Q! ]作者: 回到未来 时间: 2018-10-19 08:17
当然是…………按标准做，什么灯就按什么灯的标准作者: 281680153 时间: 2018-10-19 10:46
灯具分类型的哦 LED是1.06倍作者: xiaoning 时间: 2018-10-19 13:57
除特低电压以外的钨丝灯的温升是光源达到1.05倍额定功率时的电压,其它灯具是1.06倍额定电压.作者: duanemail 时间: 2018-10-19 14:07

除了钨丝灯，其他都是按照1.06倍的额定电压，你的光源应该是LED吧。作者: liuchenglong 时间: 2018-10-20 17:10
