LED beads do not match the LED driver power supply. If the power of the bead chip is insufficient, the light source will flicker. If the current is too high, the bead will turn on and off. The wire or copper wire is broken, resulting in the lamp bead is not bright. Increase the output electrolytic capacitance.

The driver has the function of overheating protection, but the heat dissipation performance of the bulb material cannot meet the requirements. The driver's overheating protection function will flicker and disappear when it starts to work. A two-stage scheme (AC/DC, DC/DC) is used. The first scheme is "increase output electrolytic capacitor". In theory, the scheme can use electrolytic capacitors to absorb part of the AC ripple, but practical experience tells us that if the ripple is controlled within a certain range (10%), it is difficult to further reduce it unless the electrolytic capacitors are added.

No matter what the cost, it cannot be fundamentally eliminated. The second approach is the "passive PFC solution using populated valley values", which is the most popular approach. Non-isolation solutions are commonly used in Shanghai Jingfeng Mingyuan or Shanghai Duty Ratio Solutions. The isolation solution can be a core link or IWATT (the earliest solution, which has been largely eliminated). Two large capacitors and three diodes are used for power factor correction.
