请问,对于使用卤素灯的灯具应该有个UV filter?一般来讲,我们会用一个玻璃片而以.但是我们是否要在玻璃片上注明是"UV filter"?UL是否有强制要求啊!

如果卤素光源沒有灯泡本身的玻璃做防护,则需要提供一个UV Filter

應該是“沒有”吧

感谢sinian519,fasten的帮助与支持!祝新年快乐!

按照标准,没有此要求,如果你的客户提出此项要求,这个就属于客户的特殊要求,如果成本增加不多,你也可以答应客户,如果成本增加比较多,就可以通过谈判请客户承担一部分费用,因为这个不是标准必须要求的.

谢谢!你们解释的非常好!UV filter 是有的,但是要不要在玻璃上标明这就是个UV filter呢?

上面fasten已经说清楚了,按照UL153标准,如果卤素光源只有灯泡本身的玻璃做防护,则需要提供一个UV Filter,如果除了灯泡还带有防护罩,则需要满足以下要求:
防护罩如果是玻璃,则必须是防UV的sodalime glass,或者其他玻璃(波长要满足标准要求),厚度最少3.2mm.塑料为2.4mm.

52.5.1 A portable luminaire intended for use with only double envelope tungsten-halogen type lamps and
that is marked in accordance with 171.2.2 or 171.2.4 is determined to comply with the UV filter
requirements in this Section.
52.5.2 A portable luminaire that is able to be used with single envelope tungsten-halogen type lamps –
lamps not provided with an integral outer glass envelope shall be provided with a UV filter.
Exception No. 1: A portable luminaire in which the light source is located 5 feet (1.5 m) or more above the

52.5.4 A UV filter shall be constructed of:
a) Sodalime glass, or glass with transmission characteristics in accordance with Table 52.1.
Either type shall be minimum 1/8 inch (3.2 mm) (3.0 mm metric trade size) thick for over 100 W
or 3/32 inch (2.4 mm) thick for 100 watts or less; or

有没有依据啊!我也认为是不需要的,但是我们的客人说一定要的,但是也拿不出来证据的.我也不想与他们去争了,但是我想真正弄清楚这个东西究竟要还是不要.谢谢大家!
