PURPOSE: An electronic neon transformer is provided to stably accomplish the control of a neon tube by stably operating electric field effect transistor. CONSTITUTION: A low pressure electronic neon transformer comprises input terminals(L3,L4), a pressure lowering trans(T2), a rectifying circuit(4), and an oscillation controlling circuit(K). An electric power source is inputted in the input terminals(L3,L3). The pressure lowering trans(T2) lower the pressure of an AC power source which is inputted into the input terminals(L3,L4). The rectifying circuit(4) rectifies the pressure lowered power source to a predetermined DC current. The oscillation controlling circuit(K) comprises an unstable multi-vibrator(OSC). The output ends of the unstable multi-vibrator(OSC) are connected to gates(G,G') of field effect transistors(FET1,FET2).
