BULB SAVER CIRCUIT
Proven design of an electric bulb life extender is reproduced here .You can easily construct this little circuit using generally available electronic components.First of all,make your own PCB using the layout guidance given above.Next assemble the circuit and enclose it in a proper plastic box.Note that the PCB layout is not in actual size!
Input:AC 230V supply
Output:AC 230V Bulb(100W max)
D1,D2 = 1N4007 Silicon diodes .
R1 =10Ω 5W wire wound resistor.
R2 =4Ω7 NTC resistor.
C1 = 1uF/630VAC polyster capacitor.
