欧盟LVD指令新要求下常用灯具EMF暴露评估分析
Analysis of Assessment for Typical Lamps Related to Human
Exposure to Electromagnetic Fields under the New Requirements of
the EU LVD Directive
摘要 根据EN 62493,说明了灯具人体暴露的评估计算方法,对电流密度测试布置、设备及测试步骤进行详细说明。对常用的不同类型(节能灯、LED灯、卤素灯及气体放电灯)、不同功率的灯具在
20 kHz~10 MHz频率内分别进行了感应电流密度测试、计算了评估系数F,获得了同类型、不同功率灯具,同功率不同类型灯具的电磁场辐射发射变化评估,以供灯具的生产商对比参考。

Abstract In this paper have been described the calculation method and the
assessment of lighting equipment related to human exposure to the electromagnetic
fields according to EN 62493. The measurement set-up, equipment and procedure to
measure the induced current density are given in detail. The induced current density
was measured and the factor F was calculated for frequencies from 20 kHz to 10 MHz
around common lighting equipment (self-ballasted lamp, LED lamp, Halogen lamps, Gas
discharge etc.), the assessment was analyzed with the change of the power for the
same type lighting equipment and with the different type for the same power. We hope
to suggest the reference for lighting manufacturers.
Keywords ICNIRP; LVDdirective; human exposure for electromagnetic field; induced
