Normal turing light on of fluorescent lamp and the instruction drawing of circurit replacement

Please use 0.75mm2 insulation power supply for the By-pass circuit
Starter-type light on circuit (Fig.1)
There are 3 kinds of starters.
Lighting-initiated type(starter)
This approach is what to preheat the filament, and then to discharge. Processing circuit and inflicting electric tension, then the contacts of the starter close, and short-circuit current flow out, so that the filament was preheated. When the filament is heating, the contact opened, then the coils in stabilizer produced the high voltage to turn on the fluorescence. After the light opening, the glow lamp doesn’t work because the lamp discharged itself, thereby release the electron continuously.
Manually-initiated
To connect the start switch instead of the starter. The stabilizer produces the voltage, and then start to discharge when the start button was pressed, to preheat the filament, and to release the switch.
E-initiated
Quick Start-style Lighting Circuit(Fig.2)
As the name implies, it was improved, the fluorescent opened immediately when the circuit was connected. It doesn’t use the starter, turning the light on via the combination of quick start shaped light of starting auxiliary conductor and magnetic flux leakage transformers stabilizer. For the auxiliary startting, sometimes the closer conductor is instead of the apparatus.
Converter type (electronic type) lighting circuit(Fig.3)
Using the converter (electronic stability control), Once the commercial power had been changed to DC 50 or 60Hz, it would further convert to the high frequency 20 ~ 50kHz to turn on the light. To turn the light on through the high frequency, and the guide number increased per second, so the brightness is increased every wattage compare with the old lighting frequency of commercial power.
