A question with such a title was asked by the reader Aleksey.
This is the 36th Q&A publication. You can familiarize yourself with some of the past parts by clicking on the links after this article.
The text of the question itself was as follows:
Replaced 12 V g4 lamps in the luminaire with LED ones. If all LEDs are on, they are very dim, almost imperceptible. If I insert one halogen into the circuit, everything works as it should. How to get out of the situation? Is it possible to replace one halogen with some kind of diode or capacitor, for example?
I considered the issue and advised Alexey within the framework of my knowledge and qualifications as follows:
Yes, that's right, many modern chandeliers are equipped with a power supply, radio, logic block and circuit switch. Due to the fact that many models were designed for halogen or incandescent bulbs, the logic block in the chandelier is designed for a certain load. For which an upper and lower limit is defined.
Since you replaced the light bulbs from the range permissible for automation with LED ones, which have much less power, the logical unit simply does not perceive them as a lighting device, therefore they do not have a full power supply submits. As soon as you connect enough load for the unit, it switches the entire lighting circuit.
To solve the problem, I personally reworked the chandelier, which made it possible to install all the LED lamps. Therefore, I recommend that you include a resistor in the circuit of one of the lamps, which will help create sufficient load without replacing the lighting fixture.
The capacitor in this case will not help you in any way in the DC circuit. With a diode, it is quite difficult to select parameters, so I recommend that you use a resistor.
