RE: EXPLANATION OF HOW A LED BULB WORKS AND REPAIRING IT - FIRST PART (ENG/SPN)
You are viewing a single comment's thread:
I hate throwing out LED bulbs. Unfortunately many LED bulb manufacturers appear to have planned obsolescence in mind. All of the LEDs are on the same circuit and one has to break the outer bulb to get to the electronics.

Hello @yintercept.
Totally agreed. If something can be repaired we have to find out how, that way we feel constructive, useful, as well as saving a bit on money.
On some LED bulbs that outer shield can be taken off by pressing it around with a thing flat screwdriver, so as to "unglue" it from the rest of the bulb, exposing the LED array. That way you could measure the volts coming from the rectifying stage. If there is nothing at that output, then you would be better off buying a new one since the reapir could be more expensive.
Please, have a look at the 2nd part of this post which I would be publisihng shortly. Probably you may see how to disassemble some of them.
If I can be of any assistance, I will be glad to do it.
Thanks for your comment.
Take care..
I often open up the bulbs and tear out the bits of copper inside. I think is it worthwhile to like recyclable materials found in electronic objects. There is often an appreciable amount of copper in motors, which i see is the subject of your current post.
We are used to tossing out light bulbs as incandescent and fluorescent bulbs depended on the gas in the bulb. Fluorescent bulbs contain a little mercury which needs to be disposed properly.
