IEC 60598-2-17:20 17规定了室外和室内使用的舞台、电视、电影和摄影工作室灯具（包括聚光灯和泛光灯投影仪）的要求，电光源的电源电压不超过1 000 V。 这第二版取消并取代了1984年出版的第一版和修正案2:19 90。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a）将适用范围由光源扩展至电光源，并将17.1中的“钨丝、管式荧光灯及其他放电灯”改为“电光源”。 b)考虑到存在许多具有不可更换光源的LED灯具，以及没有玻璃灯泡的光源，或者具有低工作温度的LED灯具:因此，相关条款的适用范围仅适用于具有玻璃球泡灯或具有高表面温度的可更换光源灯具。

IEC 60598-2-17:2017 specifies requirements for stage, television, film and photographic studio luminaires (including spot and floodlighting projectors) for use outdoors and indoors, with electric light sources on supply voltages not exceeding 1 000 V.
This second edition cancels and replaces the first edition published in 1984 and Amendement 2:1990. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) extension of the applicable scope from light source to electric light source and replacement of "tungsten filament, tubular fluorescent and other discharge lamps" with "electric light source" in 17.1.
b) consideration of the fact that there are many LED luminaires with non-replaceable light source, and light source without a glass bulb, or with low operation temperature: the applicable scope of relevant clauses therefore only applies to replaceable light source luminaires with a glass bulb lamp, or with high surface temperature.
