Luminous Phenomenon of Silent Discharge Using a Piezoelectric Transformer

Light emission is observed in the silent discharge that produced by a piezoelectric transformer (PT) in nitrogen. The spatial distribution of light emission is observed in the λ mode vibration of the PT and compared with the potential distribution on the PT surface. In the case of λ mode vibration,...

Description
Summary:Light emission is observed in the silent discharge that produced by a piezoelectric transformer (PT) in nitrogen. The spatial distribution of light emission is observed in the λ mode vibration of the PT and compared with the potential distribution on the PT surface. In the case of λ mode vibration, light patterns appear at four areas around the PT. The spatial emission and potential distributions match clearly, indicating that the intensity of light emission is related to the electric field intensity around the PT. It is observed that luminous patterns alternate around the PT by sinusoidal driving voltages, as induced by the piezoelectric effect of elastic vibration on the PT surface. The temporal variation of emission intensity follows the induced electric field on the PT.
