I stole a dead light bulb to autopsy (Patreon)

Inside a STOLEN (faulty) LED bulb

Maybe I should become the bulb-fairy and swap dead bulbs for new. This isn't the first dead LED bulb I've snaffled from a pub. The most notable one being a blue LED downlight from a bar of ill repute. In this instance though, I very much doubt they'll even notice it's missing, since it had been this way for a very long time. On a plus note, they are now saving 2W of wasted power, and the extra air conditioning load needed to remove it. Totally crunchy inside, but enough evidence to trace the key chip manufacturer and deduce which of the example schematics had been used. It also explained why a dead bulb was still dissipating 2W of power as heat. One of the key points of failure was the use of all the LED filaments in series, meaning that a single failed LED caused the whole bulb to flicker and go dim. It's also quite interesting that the reason the base was still getting hot and dissipating a surprising 2W of power was because of the triac-dimmer friendly extra load section. It also identified a mystery component that I have come across in the past, but never worked out what it was.
