    @Imran You should have raised a new topic for your question. Reply for a topic must be relevant to that topic only.

    Anyway, this site is yet a new born baby. And there’s just one topic only.

    About your question, I will write an article regarding it in the blog section of this site as soon as possible. Stay tuned!

    @imran, yes there is bridge rectifier used in led bulbs with capacitors as dc purifiers. Voltage is step downed by using magnetic core high frequency transformers. ac current is being rectified partially via bridge rectifier and small ac pulsating in dc current is filtered by capacitor. Use of some resistance allows to slow down the flow of current and feed the LEDs their needed one approx. 0.02micro amps. In many lamps instead using X’mers they divide voltage by connecting LEDS in series. In this way LED lamp work.

    I wish if Er. Kiran can check my comment and do clear my dobts if any.
