The photo shows how these diagrams look after burnout. So, to prevent this from happening, I decided to completely abandon these boards and use inside the lamps only a bridge rectifier circuit and an electrolytic capacitor with a resistor connected in parallel with it. This scheme is universal for all lamps and is calculated taking into account the built-in matrices and the use case with the system. The system is an uninterrupted, stabilized, with a special form of AC voltage unit and additional devices - dimmers (dimmers). They allow you to adjust the brightness of the glow of chandeliers, lamps and are very convenient in practical use.
The system unit consists of a separate box, two built-in switching power supplies, a battery compartment and a converter module. The block is calculated from the value of the maximum load on the lighting of the apartment. Using this system, the lamps simply do not burn out and do not pulsate.And most importantly, all this in general allows you to save time, money, nerves and health.
