The Electrodeless lamp is intended as a high efficacy replacement for the incandescent reflector lamp in many applications. but Increasing awareness of electromagnetic compatibility(EMC) issues in lighting application, the problems of interference generation by electrodeless fluorescent lighting system have been highlighted. In this paper, Maxwell 2D finite element analysis program(Ansoft) is used to obtain electromagnetic properties associated with the coil and nearby structures. and also evaluated Flux B, H by changing the input current.

This paper reviews electrodeless lamp technology. The lamp has very long life time but very high cost compared to conventional lamps such as fluorescent lamp. For optimizing the overall system in performance and cost power supply as well as lamp is very important. First, the paper describes various electrodeless lamps and its market condition. Then, a lot of circuit technology for constructing the power supply is reviewed and circuit characteristics are discussed

Electroded lamps operated at a high enough frequency can usually be modeled for the purpose of ballast design, as a resistor. Electrodeless fluorescent lamps include other components such as the arc tube's inductance. But that's impedance is small and so will be neglected in this paper. So, electrodeless fluorescent lamps is modeled as a resistor. A SPICE compatible model was developed for an electrodeless fluorescent lamp(OSRAM SYLVANIA ICETRON/ENDURA 150W).

Electrodeless fluorescent lamps utilizing an inductively coupled plasma were found to have a long lifetime and high efficacy and now are used in some indoor and outdoor apllications. This paper gives a basic data of electrodeless fluorescent lamp 'Endura'(OSRAM SYLVANIA ICETRON/ENDURA 150W). The experimetal system consist of ENDURA 150W/840 Coolwhite lamp and ENDURA 150/200-240 S ballast.

Pure Xe, Kr and Ne atoms and Mixures of Xe-Ne used in fluorescent induction lamps(FILs). However standard regulation of FILs is not made up until now. Therefore, the electron transport coefficients, the electron drift velocity W, the longitudinal diffusion coefficient NDL and the ionization coefficient $\alpha$/N in pure Xe, Kr, Ne gases and Xe-Ne mixtures(1:9, 5:5, 7:3) were calculated over the wide E/N range from 0.01 to 500 Td at 1 Torr by two-term approximation of the Boltzman equation.

There are lots of merits in the electrodeless lighting. But it is not widely used because the price is too high though it has very good quality and efficiency. So it is necessary to develop a electrodeless lighting which can be widely used with its merit.

This paper presents a study on the modeling on the dimming control of electronic fluorescent lamp. The resulted models of the lamps were applied the two dimming control methods, one is the variable switching frequence and the other is the variable dc link voltage method. And the comparison of the dimming characteristics between the two methods was presented. Theoretical predictions were verified the experimental results on a 100w electrodeless fluorescent lamp.

This paper gives an assessment criteria and reliability improvement for high frequency power supply of high efficacy electrodeless fluorescent lamp. The electrodeless fluorescent lamp system consist of electrodeless fluorescent lamp, high frequency power supply and lighting fixtures. The high frequency power supply has a shortest life at the system. Therefore It is need th assess the Failure Rate or mean Time To Failure(MTTF) for the high frequency power supply of electrodeless fluorescent lamp system and improve the reliability at design. We suggest the assessment criteria and improve methods of the reliability on the design basis for the electodeless fluorescent system.
