摘　　要：感应式无极灯通过电磁感应方式将能量耦合到灯泡内以使发光,在射频下一般是采用电感耦合。本文从电磁理论出发,在似稳条件下,针对新发明的低射频电容耦合,以工作频率在230 k Hz左右无极灯为例,阐述似稳条件下低射频电容耦合的原理:以电磁基本理论为基础,近似计算和推导了在似稳条件下低频电容电路产生的涡旋交变磁场和感应涡旋交变电场耦合的可行性,首次对低频电容感应耦合的理论进行了探讨,我们的实验(将另文讨论)也证实了低频电容感应耦合的可行性。Induction electrodeless lamp will be to make energy coupled to the light bulb glow, under the radio frequency usually adopts the inductive coupling, by electromagnetic induction way. In this paper,based on electromagnetic theory, under the condition of quasi-steady, we focus on the Low-frequency capacitive coupling, and take, for example, the electrodeless lamp working at about 230 kHz, then, sets forth the principle of low rf capacitive coupling：Coupling feasibility , caused by Low frequency capacitance vortex of alternating magnetic field and induced vortex alternating electric field coupling, was derived by low frequency capacitance circuit of approximate calculation and from the height of the electromagnetic theory for the first time, Our experiments （will be discussed in another paper） also proved the feasibility of low frequency capacitance of the inductive coupling.
