السلام عليكم ورحمة الله وبركاته
ارجو منكم توضيح فكرة عمل اللمبة (CFL) بالتفصيل مع الذكر دور كل عنصر في الدائرة ليكن بابا لاستفادة جميع الاعضاء.... واليكم شرح الموضوع لقد وجدت من خلال البحث في جوجل ولكن اعتقد شرح غير جيد وحتى ممكن اقول بانكليزية غير مرتبة .واتمنى من الجماعة الذين لهم معلومات على الموضوع تفضلو بشرحها بطريقة اوضح

Electrical construction
Princip of function we explain on a LUXAR 11W lamp. Circuit contains supply section, which includes interference suppressor L2, fuse F1, bridge rectifier from 1N4007 diodes and filtering capacitor C4. Starting section includes D1, C2, R6 and diac. D2, D3, R1, R3 have protect function. Other parts have normal operation function.

Lamp start
R6, C2 and DIAC mades first pulse to base of transistor Q2 and cause his opening. After start is this section blocked by diode D1. After every opening of Q2 is discharged C2. There is not possible to collect enough energy for reopening of diac. Next are transistors excitated over very small transformer TR1. It consists of ferrite ring with three windings (5 to 10 coils). Now are filaments powered over capacitor C3 from voltage rises from resonant circuit from L1, TR1, C3 and C6. Than the tube lights up is resonation frequency specified by capacity of C3, because he has much lower capacity than C6. In this moment is voltage on a C3 over 600V in a relation to used tube. During start is peak collector current about 3 to 5 times bigger than during normal operation. When the tube is damaged, there are hazard of transistor destroying.
