Self Reversal Effect of the High-pressured Diatomic Sulfur in the Electrodeless Sulfur Discharge Lamp

무전극 황방전등에서 고압 이원자 황($S_2$)의 자체 역전 효과

Abstract

A prototype electrodeless sulfur lamp was developed and investigated the spectroscopic characteristics. The emission spectra of $S_2$ in the microwave-discharged eletrodeless sulfur lamp (ESL) were studied at various input power. The emission spectra of the ESL shift to longer wavelength with increasing of the input power. We have shown that this is due to the self reversal effect in the high pressure gas discharge. We also show that the self reversal effect increases as the rotation of the discharged bulb. The spectral distribution of the ESL shifts about 45 nm toward visible region from UV region due to the rotation of the lamp bulb.
