Abstract(in English) | Electromagnetic noise radiated from inverter circuit in the LED bulb influences to communication systems. In this paper, to make clear the electromagnetic noise radiated from the LED bulb and the power supply line, the electromagnetic distribution is calculated by FDTD method and measured by experiment. The near electric field around the LED bulb available in the market is measured by monopole antenna. It is revealed that it is possible to evaluate to noise level from measurement of the near electric field by monopole antenna. The near magnetic field is only measured above the power supply line, but not around the LED bulb. It means that the electromagnetic noise is radiated from common mode current flowing into the power supply line. From FDTD analysis result, the power supply line and the LED bulb radiate the electromagnetic field as the electrical type antenna. The noise evaluation for the electromagnetic noise radiated from LED is necessary to measure the electric field. |
