Icebox operating pilot lamp circuit
Installing operating light on the mains jack makes it convenient to watch icebox's starting and stoping, and can add the beauty to the mains jack to. The circuit isshown asdiagram 1.It uses the secondaryinduced current of current transformerto lighten light-emitting diode.The current transformercan look for a slightly larger transistor radioinput or output transformer.And the data can bechanged according to the diagram. people should pay attention to winding-to-winding insulation. Current-limiting resistor R can be chosen in several to tens of ohm.
