LED illuminated lamp, LED ceiling lamp and so on are widely used in the conventional home and commercial facility. However, the electromagnetic noise radiated from the inverter circuit implemented in the LED illumination unit has make a problem to radio communication systems. In this study, the electromagnetic noise amount for the number of LED bulbs and different wiring pattern are discussed. From the measurement result of voltage terminal noise, the harmonic component of the switching frequency is observed below 5MHz, however the different of electromagnetic noise amount by the number of LED bulbs and wiring pattern is not observed. The current noise is largest about 150MHz. When the number of the LED bulbs increases, the current noise value is saturated at 10th LED bulbs from the measured results, and the peak frequency is decreased. There is the difference of electric field radiation between cascade and brunch connection below 200 MHz. |
