Why don't LED lamps work after replacing halogen ones?
Help to understand the strange work of LED bulbs that are turned on instead of halogen ceiling lights. The switch is ordinary, without backlight. Halogen replaced 30W four pieces, 7W LED? turned on the switch, the light was bright and turned off after 7-10 minutes, I turned off the light supply by the switch and turned it on again after 15-20 seconds, turned on, but turned on again after 7-10 minutes, I assumed the problem was in the switch, no everything is jammed and the contacts are clean . Instead of one LED bulb, I put one halogen, the operating time changed (glows up to 15-20 minutes. I suspected a problem in the wiring, but what could happen if the 220v halogens worked in this circuit. I have never encountered a similar problem in the last 15 years. Help where to look for the reason.
Are the lamps exactly on 220V? Not on 12V? If yes, then you can try to use the exception method - turn off the switch and connect its wires directly (de-energize the apartment first), if the light does not go out - the problem is in the switch. I also advise you to check all possible connection points - twists in the boxes, the terminals of which the chandelier is connected.
Did you buy lamps all at once and in one place? If you leave only 1 lamp (unscrew the rest), will it also turn off? Try to buy a lamp from another manufacturer and check. Maybe they just overheat.
If, nevertheless, you are talking about it for 12V halogens, then this behavior is likely, you need to replace the electronic transformer with a power supply unit with an output constant voltage (DC) of 12 volts. And everything will be fine.
