嵌入式天花灯一般不用做吊重测试.
嵌入式天花灯能吊多重,安装孔的大小会有直接影响吊重,不管是用卡簧还是用弹片.

按照UL1598,嵌入式的不需要做吊重测试(loading test),标准中的吊重测试(loading test)是针对表面安装灯具(surface mouned)要求的。作者: xmozlx 时间: 2012-1-18 16:34
不做吊重测试,但对弹簧力度是有要求的,作者: 622 时间: 2012-1-18 16:34
是这个测试吧?
16.15 Loading
16.15.1 A supporting device shall support a load equal to four times the total mass to be supported under
intended operating conditions for 1 h. The load shall be applied in the direction of actual loading
conditions.
16.15.2 Where more than one support is provided, the load shall be distributed as follows:
(a) where the parts supported are no more than 11.3 kg (25 lb), the full load shall be applied to
each support; or
(b) where the parts supported are more than 11.3 kg (25 lb), the distribution of the load shall
be similar to that encountered in the field.
16.15.3 There shall be no deflection or deformation either during or after loading that reduces electrical
spacings or compromises safety.作者: 民前八方 时间: 2012-1-18 16:34
嵌入式灯具是不需要做的。只有表面吊装的才需要,一般是灯具的5倍重量测试作者: 三笑fvlx 时间: 2012-1-18 16:34
楼上的,应该是4倍于灯重作者: ranshudeng 时间: 2012-1-18 16:34
学习了,我只做过吊灯的悬挂测试的,
一般用铁链连接的,铁链圆环一般是焊接密封的。作者: d601022246 时间: 2012-1-18 16:34
