Repairing of these lamps not pay off, because price of cheaper types are very low now and price of human work is much higher. Both plastic parts are clicked to himself and sometimes glued. Most of these compact fluorescent lamps use same or very similar wiring. After every opening of Q2 is discharged C2. Inner side of tube is faced with luminophore, which transform UV light in to the visible light. Failures Common failure is broken capacitor C3. It lights up immediately after power-up. Fluorescent lamps are available usually in these color temperatures: Warm white K Cool white K Daylight K Most often we meet with "warm white", which is close to classic bulb and which is most pleasant to people. Mechanical construction Lamp is usually compounded of two parts.

    Ballasts was broken due to blowed electrolytic capacitors.

    Circuit is classic. Because there are used switched converter, which works on tens of kilohertz, that CFL lamp doesn't "blink" in comparison to classic strip tube lamp.

    Maxilux 15W Lamp Maxilux 15W use classic wiring. Than the tube lights up is resonation frequency specified by capacity of C3, because he has much lower capacity than C6.

    For closing of lamp you can only click both plastic pieces to himself.

    Photography of open ballast. Circuit contains supply section, which includes interference suppressor L2, fuse F1, bridge rectifier from 1N diodes and filtering capacitor C4. Nuno Sucena Almeida succesfully repaired ellectronic ballast and sent me his schematics which I now show to you.

    Repair of electronics Repair of electronics usually means change of capacitor C3 if he is brobek. This lamp compared to other has a right dimensed components, that electronics probably can live longer. Second much bigger piece has slots for bills from the inner side.

    Both plastic parts are clicked to himself and sometimes glued. Other parts have normal operation function. Look at photo of opened lamp. There is not possible to collect enough energy for reopening of diac. In a normal situation, when transistor opens, that current to TR1 increasing until his core is saturated and next his feedback to base drop away and transistor closes.

    Common failure is broken capacitor C3. Compact fluorescent lamp use vacuum pipe similar to classic strip lamp and princip of energy transformation to light is same.

    Normal operation When the gas is ionisated in a pipe, C3 will be practically shorted and thanks to this frequency goes down and changer is now drived only by C6 and changer generates much lower voltage but enough to keep the light on. Compact fluorescent lamp Bigluz 20W use classic wiring with a small changes.

    Most often we meet with "warm white", which is close to classic bulb and which is most pleasant to people. Informations are from retracing of lamps and from sources in a link section.

    Sometimes can be pipe broken due to internal tension and temperature difference.

    Whet the pipe doesn't lights up on time, there are risk of destroying transistors Q1 and Q2 and next resistors R1, R2, R3 and R5. For closing of lamp you can only click both plastic pieces to himself.

    Overflowing energy mercury radiate in a UV light form. Lamp was on continuous for one year, which is over hours. Best transistors for replacing of original types are MJE, but it is not easy to find them.

    There arise low temperature plasm.

    Usually you can carefully leverage with a small screwdriver sequently to round to the gap between both plastic pieces for releasing of glue.

    Light color "warm white" brings light of classic bulb and doesn't have a small pink tone like others. Wiring is classic. Schematics and photos Bigluz 20W Compact fluorescent lamp Bigluz 20W use classic wiring with a small changes.
