Hey guys, welcome back! :D

Today I got a teardown video of a failed LED light bulb for you. This thing suddenly stopped working without warning and I wanted to see why. The cause was pretty simple to find but I did take a closer look at the LED driver (power supply) design because I never had anything to do wich such a thing. It is not your standard AC to DC power supply because it operates solely with an oscillating MOSFET and limits its own, maximum voltage by the load applied. So essentially by design.
