一般照明设备电磁兼容性抗扰度要求第1部分:目标光闪烁计和电压波动抗扰度试验方法

[中文适用范围]： 本部分IEC 61547描述了一种客观光闪烁计，可用于以下目的： - 在不施加电压波动的情况下，测量所有照明设备在稳定市电供电下的固有性能，即光照闪烁； - 测试照明设备对交流电上网电压波动干扰（无意）的免疫性能，即光照闪烁；在此测试中，向交流电施加一组定义的电压波动，并确定照明设备对该干扰的免疫性。 除上述两个目的外，照明设备对因例如市电信号而产生的有意电压波动的免疫性能也可进行测试，但本文档未对此作进一步描述。本文件旨在为评估照明设备在光照闪烁方面的性能建立共同的客观参考。色光波动（色闪）不在本测试考虑范围内。此方法可应用于IEC技术委员会34范围内的照明设备，如灯具和灯具，旨在连接到低电压电力供应。独立辅助装置（如驱动器）也可通过对该辅助装置应用代表性光源进行测试。 本文档中描述的客观光闪烁计和电压波动免疫方法基于IEC 61000-3-3电压波动限值标准和闪烁计标准IEC 61000-4-15。本文件中描述的客观光闪烁计可应用于客观评估由任何类型电源供电的照明设备的闪烁，包括交流市电、直流市电、电池供电或通过外部光调节器供电。本文档描述的特定电压波动免疫测试方法适用于额定电压为120 V AC和230 V AC，频率为50 Hz和60 Hz的照明设备。注2：该方法的原理可应用于其他标称电压和频率额定值。 [外文原描述]： IEC TR 61547-1:2020 describes an objective light flickermeter, which can be applied for the following purposes: - measuring the intrinsic performance of all lighting equipment without the application of voltage fluctuations in terms of illuminance flicker; during this measurement, the lighting equipment is supplied with a stable mains; - testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation disturbance on the AC mains in terms of illuminance flicker; during this test a set of defined voltage fluctuations are applied to the AC mains and the immunity of the lighting equipment to the disturbance is determined. Apart from the above two purposes, the immunity performance of lighting equipment can also be tested against intentional voltage fluctuation on the AC mains arising for example from mains signalling. This is however not described in further detail in this document. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the scope of this document has been clarified to make a distinction between flicker testing without voltage fluctuations to measure the intrinsic performance of lighting equipment and flicker testing in which a specific set of voltage fluctuations are applied in order to measure the immunity of the lighting equipment to voltage fluctuations present on the mains; - the test procedure for flicker testing has been clarified.
