Repairing an LED bulb

[dedeleco]

LED lamps are not all the same with the same number of LEDs or the same assembly and I do not have this type at home.

RV-P will put you full of saturated magnetic amplifiers, from the 1920s to 1970s, without any semiconductor power transistors !!!

- Error, my "dear" Dedeleco! I put on the subject "Modified auto alternator for wind turbine" a diagram of a regulator with 3 transistors for winding saturation coil in addition to the winding of the alternator! But since you are "clogged with emery" and you seem "a bit grumpy" (the grumpy smurf !) and that you always give me the impression of getting up "with your left foot" every morning, you have, as usual, "zapped" the subject!
- So, if you are so smart, give me a SIMPLE solution based on piloted thyristors! I give you a track: replace 3 diodes of the three-phase Graetz bridge with thyristors. Chick?

In this case, the diagram posted by RV-P is completely correct.

- This is the diagram that I "took" from the photo of the said lamp published earlier on this subject!
- @ +!
PS: DD, don't believe that, because you are an expert econologist, you are an econology expert !

Fun !!!

Ah the TGV thyristors, for an LED lamp on the three-phase wind turbine, indicated on wikipedia:

- It's exactly that ! Now find me a simple and efficient control circuit for these thyristors, in the DIY sense !!!
- Look well: it will keep you occupied and it will prevent you from "complaining", for once, maybe ...
