请问,无非正常状态的灯具耐久每天需要关断3小时吗?作者: sea-blue 时间: 2010-8-19 14:04
不用啊,正常持续工作240个小时就可以了!作者: chqonline 时间: 2010-8-20 11:24
问过一个认证公司的安规工程师,说要21小时开,3小时关。标准上说得不太清楚。想听听大家的意见作者: 雨花石 时间: 2010-8-20 11:45

标准的语句我拷下来了。最后一段的意思实在是没法理解,特别是最后一句,用灯丝灯泡的灯具要怎么做耐久?还请高手解惑。谢谢!作者: barondavids 时间: 2010-8-23 09:02
10个cycles,每个cycles21小时开,3小时关。* B& }0 p/ x9 b; U* F! E$ s

the total test duration shall be 240 h (i.e. 10 x 24 cycles at normal operation),如果2楼和4楼认为这里的"cycle“和上一段指代的"cycle"不一样,那这里为何不对"cycle"做特定解释。况且,每个cycles点24小时直接点240小时的话,又何必加括号分"10 x 24 cycles"。 $ u9 q+ H: m4 v" H/ g$ _ ?

楼上说的有点道理。那最后一句,for filament luminaires, the total test duration shall apply in all cases. 是什么意思?作者: xiqiangzhang 时间: 2010-8-23 10:40
需要21小时开,3小时关。标准有明确的要求。作者: barondavids 时间: 2010-8-23 11:34
