説明
Piezoelectric transformer (PT) is a high voltage generating device which is small-sized and high efficiency energy conversion. Because of these features, the PT is used as power supply of back-light for liquid crystal display (LCD) and has promoted to the recent development in information technology (IT). On the other hand, we discovered that the PT does not only act as a high voltage generating device but also a silent discharge exciter. This paper describes the experimental result of luminous phenomena of the silent discharge using the PT. Spatial and temporal variations of the luminous intensity were observed by CCD camera systems. Spatial and temporal variations of electric potential at the surface of the PT are also measured using a probe electrode. As results, it was obtained that the luminous intensity distribution appeared around the PT corresponds to the electric field intensity distribution occurred by the polarization charge induced on the surface of PT which vibrates elastically. Moreover, it is also found that the place of light emission over the PT surface was determined by the polarity of potential induced on the PT surface. These results mean that the light emission around the PT occurs by excitation and ionization collision between electrons and N2 molecules.
