| Abstract(in English) | It is known that the electromagnetic noise propagate on the power line with multiple LED bulbs are increases based on the number of LED bulbs. In this paper, the increment of the electromagnetic noise based on the number of LED bulbs is estimated. It includes measuring the current noise propagate on the power line with multiple LED bulbs，extracting the characteristics of the noise by using frequency analyzing. Next, an equivalent circuit model of the power line considering the path of electromagnetic noise is extracted, and a current noise model is proposed for estimating that can estimate the increment of the current noise with the number of LED bulbs. The estimated and measured values of the increase in electromagnetic noise in the current noise waveform were compared, and it was confirmed that the two values were approximately matched．This result shows that the model can estimate the increment of the current noise flow on the powerline with the number of multiple LED bulbs.
