标题: 请教很少有人涉及的 LED 柔性灯带 UL认证问题
1. DC24V供电,低于100W的LED柔性灯带(装饰建筑物外部轮廓的那种)UL认证用什么标准?(多说一句:个人认为低压产品没必要不用做UL,但是老外说在北美没有认证的产品不好卖)
2.DC24V供电,高于100W的LED柔性灯带(class2电源用不了)UL认证用什么标准?

DC24V供电,低于100W的LED柔性灯带。其实呢,SELV只能说明产品无防触电危险,并不代表其他危险不会存在,比如火灾等,所以还是要做UL认证的;

DC24V供电,高于100W的LED柔性灯带(class2电源用不了)。如果你们的产品出货时候根本不含Driver部分的话,那就不要考量driver了,如果是灯带+电源一起出货,那class2的driver肯定用不了,class2 输出必须小于100VA的,Uoutput要小于30V(户外用的),室内小于42.4Vac或60DC(CSA规定都是42.4Vac or DC)。driver标准可以选择UL60950(非LPS的),或UL1012;

软管灯,用UL 2388 “Standard for Flexible Lighting Products”
如果是class2低压的,电源需要UL1310或者UL 1585认证的电源。
如果是超过class 2的,使用非class 2的电源。要当作高压灯具来申请UL2388。

1.谢谢
2.如果是class2供电的,能用UL1598或者UL2108来做吗?
3.如果是超过class2供电的,还要考虑UL8750中非class2供电须5va防火等级的要求吗?UL2388中是否只需v-1?

是不是问的不对啊 ?
能回答一下吗?

更正一下:UL 1585 Withdrawn。

根据UL 8750,电源接受:UL60950-1,UL1310,UL1012,变压器接受:UL5085,UL1411,UL1561.

非常感谢,
我还是想问,LED柔性灯带是DC24V供电,但是功率超过100W,该灯带用UL2388标准评估,另外其PVC包皮是否还要满足UL8750中的5va的防火要求?
