So my ceiling light suddenly dimmed and didn’t turn bright again. I replaced the led light bulbs in there and now its alls good again.
Why do led lights not simply “burn out” or fail completely? Instead they fail by producing half (or less)the amount of light they used to. This seems like a very odd way to break. Can anyone explain why they break like this?
There are multiple LEDs in the bulb and they’re overdriven, meaning they’re designed to fail. They can be modified to put out dimmer light that will last a very long time but that’s not something most people know how to or will do. Failed ones like you describe are usually repairable also but same issue that most don’t know how to or won’t.
They fail like that because one element dies entirely which messes up the circuit. If the dead one is bypassed with a small resistor the others will light back up.
It’s by design so people buy more lights. It could be made to function better and last way way longer (theocratically forever by a human’s standards).
But then the quarterly line won’t go up high enough, so it’s “bad for business”.
Like someone else commented, even the bad ones can be made to at least be slightly better with small adjustments to the circuit, but then 2 people out of 8 billions around the world would be reluctant to buy the extra luxury package on their third super yacht. So obviously it’s not worth it (╯°□°）╯︵ ┻━┻
Still better than CFLs. Those used to literally burn and catch fire, and if one broke, a nice dose of mercury vapor.
It’s not the LED but the cheap crap components used in the controller.
