No.6（2011）5.EMC evaluation and examination of LED lighting equipment

Kenichi Haji, Takeshi Kobayashi, Ryoichi Miyajima, Kazumasa Mikami

  LED products such as LED bulbs and LED tubes are recently widely sold due to the increased awareness of energy conservation. However some LED applications are not subject to the “Electrical Appliances and Material Safety Act” of Japanese law and so on. Therefore we can see some products which are not adapted to EMC.
 We have used the International standard and Japanese standard of EMC of general lighting and LED applications on the market and measured the conducted disturbances, radiated disturbances, harmonic current and supply current etc. In the paper, we would like to report the comparison and results.

Keywords
