本文描述了可在设计阶段使用的模拟技术，以便利用 3-D FEM 有效开发低电磁辐射型照明器具。特别是，通过应用荧光灯中的电子密度分布服从贝塞尔函数的理论，对被认为是照明器具最大的发射噪声源的荧光灯的建模进行了研究。通过测量验证了分析的有效性。发现在30至150 MHz频率范围内分析精度在6 dB以内
In this paper, the simulation technique which can be used at the design stage is described in order to efficiently develop low electromagnetic emission type lighting implement employing 3-D FEM. Especially, the modeling of the fluorescent lamp, which is thought to be the largest emission noise source from lighting implement, is examined by applying the theory that the electron density distribution in fluorescent lamp is subjected to Bessel function. The validity of the analysis is verified by the measurement. It is found that the accuracy of the analysis is within 6 dB in the frequency range from 30 to 150 MHz
