둥근형 무전극 형광램프의 전자계 특성

In recent, there have been several developments in lamp technology that promise savings in electrical power consumption and improved Quality of the lighting space. Above all, the advantages of ring-shaped e1ectrodeless fluorescent lamp are the removal of internal electrodes and heating filaments that are a light-limiting factor of conventional fluorescent lamps. Therefore, the life time of ring-shaped e1ectrodeless fluorescent lamps is substantially higher than that of conventional fluorescent lamps last up to 60,000 hours. There are intended as a highly efficient replacement for the incandescent reflector lamp in many applications. In this paper, maxwell 3D finite clement analysis program (Ansoft) was used to obtain electromagnetic properties associated with the coil and nearby structures. The electromagnetic emitting properties were presented by 3D simulation software operated at 250 ㎑ and some specific conditions. In addition, the optical characteristics of ring-shaped electrodeless fluorescent lamp were measured including light flux, efficiency and color temperature for each case.
