Abstract (in Japanese) (See Japanese page) 
(in English) The electromagnetic noise radiated from the inverter circuit mounted in the LED light bulb is a problem by affecting the radio communication systems. In the past, we have investigated the electromagnetic noise emitted from the power lines with multiple LED bulbs, but the cause of the noise increment and frequency variation for the number of LED bulbs has not been clarified. In this study, we investigated the relationship between the current noise and the transmission characteristics of the LED light bulbs and the power lines by modeling the two-terminal circuit. When the transmission characteristic of the power line for the number of LED bulbs is measured, the relationship between variation transmission characteristics and number of bulbs is existed under 400 MHz. The frequency of the current noise peak is not coincided with that of the magnitude of transmission characteristic. The frequency as the phase of transmission characteristic is 0, 180 or -180 degree is coincided with the frequency of the current peak.
