Why Do 230V LED Bulbs Burn Out Frequently at Home? Investigating Potential Voltage Spikes

Hello.
I have a dozen or so light bulbs at home, each with 3 LEDs.
From time to time, that is, in the range of 2-3 weeks, one of them stops shining. It's in the toilet, in the room and in the hall.
The installation is divided into several S.
The main protection is a differential switch.
When I look closely at the "burned out" light bulb, I do not see anything specific on the LEDs that would indicate the burnout of these LEDs.

What could be causing these bulbs to burn out so often. ???
(I read that voltage spikes can be the cause)

In the store, they start to suspect that something is wrong with my installation, and then they will stop accepting the warranty.

I would be grateful for any helpful answer.
GREETINGS

And what company do you have these "bulbs"? The LEDs themselves have no reason to burn out, especially all at once. Damn the converters, or even the fuse itself, which is inside. It is even possible that such a quick damage is partly deliberately planned, if you buy the lowest shelf equipment in a hypermarket. Cheap bulbs are produced with a focus on quantity (the faster they burn out, the more people will buy them), while expensive bulbs are quality-oriented (the longer and the better the bulb shines, the more people will be willing to spend a lot more money to have more reliable commodity). Simple logic.

There may be overvoltages that increase the current flowing through the diodes and they don't like it. Your security is not sensitive to this. You can think of surge protectors. Can you describe nearby receivers, are there any more powerful and inductive ones?

These bulbs are from ANS and one cost me PLN 50, which is an average shelf.
I bought them at an electrical store.

There was only a washing machine near the light bulb in the toilet, and in other places these bulbs are away from any electrical appliances. From what I remember, the cables for the lighting junction boxes were placed away from the kitchen and bathroom.

S security is divided into "light" and "contacts". And for various rooms.

What specific surge protectors do you mean by fuutro?
Regards

I mean network protectors. They have varistors and lightning arresters.

OKAY
I am thinking of a B + C class protector, namely:

Will he pass the exam ??

Simple logic, OK.

Does this mean that before buying the high-end ones, I should also install surge accessories.
Do they have these extras themselves?

Yes, but only in the case of separate installation for LED power supply
It will not be overvoltage, but the diodes will remain sublime

A very accurate question by Leszek b.
But I don't think they have any meaningful security built in.
When describing LED bulbs in the price range + - 50 PLN, it is clearly written that they are sensitive to voltage spikes.
The question is how much (within reason) I would have to spend on a single led bulb so that I would get its cost back. ???
(For me and my wallet, this limit is about PLN 50.)

In my installation, the voltage goes from the residual current device to the S protection and then to individual rooms.
Separately for the power supply to the sockets and separately for the lighting power supply.
Of course, I do not use LED bulbs throughout the house, but only in sensitive places where the light is used the most and the longest.
I have 3 ESS separately for these rooms and I would like to secure these ESS.

In your place, I primitively measured the voltage on these leds. There are many cases of burnout of "zero" before the meter and when the high load is switched on in another phase, the second one appears almost phase-to-phase. When I had such circuses at home, even the guy from the energy emergency was pissed that everything was ok (after very much persuasion, you kindly fixed it).

I think that:
I propose to test power bulbs from a good quality computer distributor with security.
Or power them from UPS and everything will be clear - sell it or not.

>= leszek.b
No offense, but the topic is about crap light bulbs that have one function. If they don't, they are up to ..... y. Especially for PLN 50. I cannot imagine building a separate installation (maybe a generator) to power such inventions.
I will probably get hit sharply, but I recommend it at a lower price of ~ 35 mm. they wrote something about 7 years - for me 10 and there is no end in sight (as in Szymon
Greetings Andrzej. )

Mr. Leszek.B for TRIALS I propose you to buy a special nuclear power plant with all overvoltage and undervoltage protections etc. that people have not yet invented. It is about specifics, not presumptions. The purchase of the cheapest voltage meter in the installation is about PLN 15 and everything would be a bit lighter .

Of course. "A little" .

Thanks.

To be honest, I have already given it back 4 times from different rooms.
When I gave it back for the first time, gentlemen said that for the first time it happened to them that someone gave these LEDs for guarantees. I was embarrassed by it.
For the sake of ignorance I gave back, my father and brother so that they don't associate us. I'm running out of people; D

Leszek.b, I can power them from ups or other contraption, but this attempt may take several weeks. If there is something wrong with my installation I would prefer to fix it right away.

I am just thinking about buying the appropriate security, I would be grateful to suggest what I could possibly buy, say up to PLN 100.

Unfortunately, there is space in my box to press the four-field security.

My friend! stop ovulating.
Get your neighbor two as a gift and wait for the end.

Well, then you have an answer for environmentalists at any cost - what is the profitability of using such "light bulbs". It does not shine, it costs a fortune and only quinole is happy about us "environmentalists" ...

As for the LEDs themselves, after a cursory review of this topic, I get the impression that most of you think that LEDs are eternal and indestructible.
These are normal semiconductors subject to statistical failure depending on many factors such as temperature, operation, overload, voltage spikes, electrostatic charges, storage and transport method and many more ...
In addition, there is the hopeless quality of the products from the Yellow River ...

And in these bulbs, a series connection is often used, and it is enough for one to be lit and not by a few.

Buy a normal light bulb or a modern halogenide and you will have real light, because if you spend another few dozen zlotys and it falls, you will be damned ... because so far these LED busts will not earn for a long time ...

Thanks for advice.
Regards

Hello
I made my own LED bulbs and there are no problems with them:
https://www.elektroda.pl/rtvforum/topic1424656.html
They will not burn out and will not burn out. I predict that in 25 years I will replace them with something more modern. Ready-made LED bulbs are so hopeless that they have no chance of being lit for a few years.

I still argue that my colleague has a problem with the installation (high-temperature-no zero). Unfortunately, if someone does not want to measure the voltage in the socket, I fall off!
You can very cheaply buy an element (attached in parallel) for the installation called a varistor for about 280V (only for a bright angel, not between phases !!!). or tear the varistor.-Everything will be explained.

Recently, a friend bought in bulk from 30 pcs and 2, 3 pcs died completely or partially and under the same conditions - new installation. Just ordinary Chinese statistics. Buy other devices, tools, etc. - it will be the same - the part does not work right away, or it will fall on the first day ... But I have a glue gun (made in PRC) which is over 15 years old, it is all cracked, it had the power cord replaced with " our "damn it still works ... the exception that proves the rule?"
