You can suggest how to solve the problem of radio interference. In short: in the suspended ceiling I have mounted 230 halogen leds, 12v led strips with transformer and ceiling radio (KB sound iselect5). When I start the radio by myself, it plays perfectly, turn on the halogen lights, still great...

Shielding does not pay, outgoing and incoming cables do as an antenna. So the effect of shielding will be small. It is best to blow out the current `` transformer '' and replace it with a normal transformer. Halogens are normal filaments or LEDs?

Of course, it's about LED power supply. All cheap Chinese DC converters emit high intensity interference. Use good quality converters attached at zero. Shielding is not effective.

I don't quite understand what this zero is about, please develop your thought.

Any example of a transormator? 20 m led, in cables of 5 m. 600 led per meter.

Switching converters in the mains voltage zero, do not generate interference.

Transformer or power supply? If this is an ordinary tape, then the power supply probably also some typical 12V (in ready lamps - floodlights etc. there are also power supplies with stabilized current), in the case of an ordinary power supply it is best to simply replace it, the fight with these inventions is doomed to failure. Upload a photo of this transformer and the LEDs themselves.

Any suggestions ? What to buy ?

Does this inverter have a PE terminal?

try to change the place for the power supplies (extend the cables and push them furthest from the radio and the antenna). Using the test method, check what disturbs the radio operation, whether the tape power supplies or halogen power supplies. Turn on one separately and check the radio and then the other and check the radio, then you will know which are interfering. Organize all cables, e.g. with a broomstick or make technical holes or get through the holes for the lamps.

I will add that the ceiling is suspended from the table to drywall. You have an idea how to get rid of the problem. ? Change the tansformator? Onscreen what is it?
Thanks for the help

You write nonsense here. The converters are supplied with DC voltage from the rectifier bridge and operate at a frequency of several kHz. There is no switching at zero here, moreover, it would not have any effect on the operation of the converter in the LED power supply.
You confuse the concept of power supply with group power control.
The source of interference are these converters - there are no suitable LC filters at the output.
They should not emit radio interference, the cheapest Chinese LED with transformerless power (without inverter).

Topic summary

The discussion revolves around resolving radio interference issues caused by 230V halogen lights and 12V LED strips connected to a KB Sound iSelect5 radio. Users suggest that the interference is likely due to the low-quality LED power supply, particularly cheap Chinese DC converters, which emit high levels of electromagnetic interference. Recommendations include replacing the existing transformer with a better quality power supply, ensuring proper shielding is ineffective, and relocating power supplies away from the radio. Users also discuss the importance of testing each component separately to identify the source of interference and the need for suitable LC filters in the power supplies to mitigate radio noise.
