LIGHTING OF FUSED FLUORESCENT LAMP

Here, a mechanism is presented by which fused fluorescent lamp can be enlighted: 

 

 

                In this model, only healthy filament of fused fluorescent lamp can emit the sufficient electrons and collected by other one to glow up. In the circuit a DC voltage is provided across two filaments with fixed polarity through a Full Wave Bridge Rectifier. In which one port inputs are two different tube-end-pins connection. And other’s port inputs are Supply Line and Choke input point connection. Choke is connected between supply line and bridge rectifier input terminal to control the current flow through back emf process. Starter is also connected across the tube to develop striking voltage. Here Starter and Choke functions same as in a healthy fluorescent lamp.
