Using Fuse Tube Light


Using Fuse Tube Light
The circuit illustrated below can RE use your thrown tube light. which usually blinks in normal circuit. A high DC voltage has advantage to glow a a weak florescent tube light. A weak florescent tube gets black at one edge. At black end Positive voltage should be applied and can be marked as anode and other clear end cathode can be marked for Negative voltage or electron will be supplied.



Please see circuit Diagram.For converting AC to DC we have used a Rectifier Circuit. Choke Should be used in series with rectifier circuit for limiting current.Rectified voltage(DC) is applied to both end of the tube.


Circuit Diagram


Part List :
Choke or you can use 100W Bulb
Diode -IN4007 or 159 X 4pcs

Save electricity ...- 1 Saving electricity: The biggest problem for us today is power shortage. It would be better for the government to abandon its tendency to criticize this and adopt methods of saving electricity. Something we can do to help this country. When thinking about where to start saving electricity at home it seemed like it would be nice to start from the kitchen. Here are some ideas, not to say it must be followed, it would be nice to follow :) Methods of saving electricity in the kitchen: Refrigerator: Refrigerator A house uses 600-1200 kWh (kWh) of electricity per year. You can follow the steps below to reduce power consumption. Keep the temperature of your refrigerator at 37-40 F. Do not push too much material into the box so that the ventilation inside is not correct. Sometimes the door does not close properly and the electricity is wasted. Check the gaskets used to keep air out of the refrigerator door once a month. If it loses its ability it should be replaced immediately. Keep the lid on when putting liquid foods inside, otherwise they will evaporate and increase the work of the compressor. Do not put hot food or wars inside. It should be kept inside only after it has cooled. рокோродு Do not open and close the curry leaves once, the coriander leaves once in a while while cooking. роЗро░ுрои்родாро▓் Use a power saver switch to save electricity if you have one in your bathroom. Do not place the refrigerator in direct sunlight at home. Things to look out for when buying a refrigerator: роТро░ு One way to reduce electricity consumption by 40% is to replace the old refrigerator with a new one on Deepavali for the coming Diwali. 165 Liter Venuma, No 200L, Single Door, Double Door, Anything Buy the right size for your needs. Don’t buy a little and push stuff inside. Make sure there are power saving modes and energy star.

Repair Of CFL



Repair of CFL



Repair of electronics usually means change of capacitor C3 if he is brobek. When burns fuse, probably will be damaged transistors Q1, Q2 and resistors R1, R2, R3, R5. You can replace fuse with resistor R5. Failures can be multiplied. For example, when is shorted capacitor there can be thermally overloaded transistors and will be destroyed. Best transistors for replacing of original types are MJE13003, but it is not easy to find them. I replaced them with BD129, but they are not available now. There exists other variants like a 2SC2611, 2SC2482, BD128, BD127, but I am not sure if they will be long-life. Original transistors are not available on our market. If doesn't matter size of case TO220, it's possible to use transistors MJE13007.

CFL bulbs basically fail due to breakdown of some very basic electronic components, which are cheap, easily avliable, and easy to test. The components are Electrolytic Capacitors, Transistors, Diodes, Transformer, and Resistors.

The most difficult part of the repair work is to open the enclosure. After the enclosure is taken off it’s found that it has the CFL, Inverter Circuit, and the Housing of the circuit that contains the screwbase.Now the repairing starts with a visual inspection.

If you find any bulged electrolytic capacitor then desolder it out from the circuit and replace it with newer one having same or close capacitance measure, and a voltage rating at least or above 250volts.

Check the transistors. Not by a visual inspection, but by testing them using an ohm-meter. In some cases it might not work due to the base drive circuit. So it’s always recommended to desolder out the transistors, and then test them.

Test the inductor/transformer for open circuit, using an ohm-meter. Check the diodes for forward resistance reading. Make sure that it has no or negligible resistance reading when it is tested reversely. Also check for open circuit.

Have a close look at the resistors. If they appear to be charred, then desolder it out and test it for its resistance reading. In some cases it’s found that resistors open circuit.30% of the failure of CFL bulbs is caused by Open Circuit Resistor that is connected to the mains supply line. It’s basically a low ohm, 0.5 watts resistors.

And if all the above components are found to be ok, then have a continuity test on the Vacuum Tube. If it’s found open circuit then, you cannot do anything further, but can obviously quit the repair work.
