The idea is to close the cut circuit. If you can solder it, it would last for sure. The pencil method would last very shortly for sure, the foil can last longer, but you need to stick it firmly which would be difficult and once the bulb heats up, the sticker glue would melt and fall.
Alüminyum folyo vardı elimde dört tanesi bozulmuştu denedim ve iki tane daha bozuldu..onlarida aynı sekilde yaptım yine iki tane daha bozuldu..nerede hata yapmış olabilirim
Лампу легко отремонтировать, и диод поменять, а не заколотить. Но не имеет смысла, после ремонта лампа работает не долго, остальные диоды(а они работают в тяжёлом режиме по температуре) так же начнут по очереди выходить из строя. Разве что поменять все на новые. Сама схема выходит из строя черезвычайно редко
This fix assumes that every LED bulb failure is caused by an open LED diode. There are other failure modes, like failed power supply. Most of my LED bulbs that failed were intermittent - flashing on and off. Aluminum foil is not a good repair because it cannot be soldered.
