Connecting LED Lamp: Identifying Unmarked Wires, White Cable with 3 Wires, Brown & Blue Cables

Hello,
I am asking you for help in connecting the LED lamp. I already explain the situation:

In the switch I have one white cable with 3 wires inside. When I check with neon sign, neither of them "burns".
The same cable protrudes from the ceiling (3 wires, white). Neon lamp, next to one of them "burns" (that is, as I understand correctly, there is a phase) and in the other "does not smoke".

In the LED lamp I have 2 cables (brown and blue) and for China I do not know how to connect it all to work. I know that I should connect brown to the phase and blue where the neon does not light up. The problem is how to connect it to the switch? At the moment, only the wires stick out from the socket and from the ceiling ..

It seems strange to me that in the switch no cable has a phase ... and in the protruding cable from the ceiling there is one with a phase (from where I don't know)

It seemed to me that it works like this:
--------- phase ------------------ wall socket - / ------------------ ---------lamp
------------ --------- neutral socket --------------------------- ----lamp

that is, there is a phase in the socket and when I change the position of the socket, I either "connect the power" or cut it off ...

and it looks like this to me:
--------- neutral ------------- wall socket ---------------- .... ------ ------ ----- neutral ceiling
--------- neutral ------------- wall socket ---------------- .... ------ ------ ----- neutral ceiling
--------- neutral ------------- wall socket ---------------- .... ------ ------ phase ceiling ------------

I don't know how it's connected from the socket to the ceiling. The previous owner had a lamp there and it worked ... also there is a way .. and I care not to spoil this lamp because I'm afraid that if I connect it wrong I will damage it ...

Please help.

I will start with a rectification - a diminutive socket, and more usually a socket is an equipment usually mounted in a box, in the wall into which the plug is inserted. In your case, speak (write) a switch, or more specifically a candlestick switch.

Simply a specialist swapped the wires in a junction box that supports this circuit and "let go" the phase directly to the lamp (ceiling), and the neutral through the switch only to the lamp. Can it be changed? One would have to learn how to run the installation in the city.

Why candlestick? Rather, it follows from the description that it is a mere connector .
For the rest, you are quite right (the installer) connected in such a way that the neutral conductor is disconnected, not phase.

I took pictures showing exactly how it looks.

Does this mean that you need to forge the plaster and check where the cable goes? Is there another way?

And finally, is it possible to connect the lamp in such a configuration as it is now?

You can connect the brown lamp to the phase and the blue lamp to neutral, being aware that the phase on the lamp is not turned off by the switch. Of course, you must turn off the voltage with the fuse when connecting.

Today, only an oral warning, but I warn you that this next tip will end in a ban. I remind you that you already have 4 warnings.

3.1.11. Do not send messages that add nothing to the discussion. They are misleading, dangerous or do not solve the user's problem.

However, you have to take into account the negative effects (flickering, not shutting down completely)

Thanks for the answers.
I understood when it came to the ceiling

The problem already appears in the switch itself. How to check which cables connect with the switch? By trial and error (peer-to-peer)?

Not necessarily. You need to find a junction box and make changes to the connections.
The switch must absolutely interrupt the phase conductor.

You cannot connect it in this configuration because the lamp is made in protection class I and requires zeroing in your installation *. When you turn off the switch, the luminaire will lose protection and a phase may appear on its housing.
I will not mention the possibility of incorrect LED operation.

*) Attention! I assume that you live in a block that is powered from the TN-C network, i.e. zeroing in sockets.
In the case of TT networks, without adapting the entire installation (renovation), there is no question of connecting a lamp made in protection class I.

Approx. Thank you all for your help.
From what I see, I have to use the help of a professional who will find the right box and make the installation done correctly (the switch cuts off the phase in the lamp).

I close the thread and wish you a quiet night.
Best regards!
