- One of my 100W LED floodlights was flickering and I had to fix it to continue with my CZcams video creation.
Video inside the Emirates A380-800 plane: • Video
Your BEST tool is always your mind -- excellent demonstration of that principle. Good Job!
:-)
Thank you so much....saved a lot of money because replaced only the chip, not the whole refletor...thanks !
You are welcome!
Beautiful content and presentation, Sir. From 74 year old Service Engineer
Thank you! We are a few elderly people on this channel...
Great video, very informative. Had the exact same problem with one of my lights, was going to bin it but I reckon its worth a quick repair now
I hope you will be successful!
Welcome back Andreas, you have been missed. I enjoyed your engineers tips. Thank you
+Dean Greenhough You are welcome. So far, nobody commented about my favorite actor/actress. Strange ;-)
+Andreas Spiess my apologies for not asking. I had a quick ten minutes to look at your video in a break at work.
So, please tell us whom the person might be😀? Also what were you doing in Dubai? What type of project?
I have to add that since I have come upon your channel, you sir have taught me so much! I kid you not.
I hope you have many happy days off work.
+Dean Greenhough For un I made a comment about a link in the comments. It is an Ad of Emirates Airways with my favorite actress. Nothing important!
An awesome repair tutorial my good friend. Thank you.
+Raymond Earle Thank you also for your nice comments!
Your English is excellent
Thanks!
Only one row of the right side of LED was working, but why did it flicker though? How to explain it in physical terms?
I do no more remember :-(
Welcome to my country any time. I learnt a lot from your videos. Keep it up
What is your country?
UAE , please next visit be my guest
Thank you! Currently, I don't know when I return...
+Andreas Spiess you know what might be great if you make short video showing some of your lap tools and why you might choose them over other
I plan to produce a lab tour in one of my next videos. Then, you will see, which tools I use.
I have LT-FL80A model which I have changed its LED Chip but again I have gotten the same flicking issue within 30 minutes keeping ON the LED.
After changing 3 or four times the LED I bought other ones :-(
Unfortunately, I can not post an answer to PirateKitty. The comment is not accepted. Can anybody else try? Or if PirateKitty reads this comment, maybe he is able to change his settings.
hi, how are you getting on with the UNI-T 804? would you recommended it?
It is ok. I did not have particular requirements, so I cannot tell you if it is good quality. I just wanted a bench multimeter.
I have other instruments form UNI-T which work fine. So, I bought the -804
I have a nice 110 v led light oprating on a motion sensor but after a few months it started flashing and flickering. So I replaced the led chip and the problem went away then after a week it started flashing again. Replaced again after a week same thing. My chips didnt have two parts with two supplies. It must be having a heat problem.
A heat problem is well possible as these chips produce quite some power on a very small area...
@@AndreasSpiess yes as soon as it heats up 40 seconds or so it gets very hot it starts to flicker and the supply voltage drops from 33 volts and to 20 volts and bounces up and down in response to the flicker.
Hello Andreas can you not reuse the old Led module and just use the good side? can use it for a smaller project a only have half the power so what 50w might be okay for a Diy lamp? Just wondering. It be a shame to get rid of it you know.
+joseph chrzempiec (josephchrzempiec) You might be right. Tu use it for experiments, you are certainly right. But I it might well be that something in the manufacturing process went wrong and because it is only one chip, the other side could contain the same error and blow up a little later. The price of a new one is around 5$. So, I prefer to go for a new one for a "production usage".
+Andreas Spiess hey Andreas so true might not take that kind of chance of of a fire or something. so for 5 dollars yeah cheap enough for another one. you are right.
Where did you buy the led lamp? Aliexpress?
I bought it locally.
The A380 runs on compressed air and li- po batteries! Anyway my led is flashing...
Hi Andreas - this, as most of your videos has inspired me! I also has a flickering led (floor lamp). I disassembled the (3) LED circuit boards and tested them on a variable voltage/current power supply - I caused smoke to come out of one of them! (I think one of the other also had just a liitle smoke...)
on the "good one" still left - I can see "4304" (sot23-5 ?) - I think it is a EC4304ANT2R - is this likely?
Unfortunately I cannot do remote diagnostics :-(
Does this device flicker?
Yes, it flickered before the repair
Andreas Spiess I meant afterwards. ;-)
I had no luck with these LEDs. Because I had 6 pieces, I had to change LEDs nearly every month. So I decided to replace them yesterday. I use now flat LED panels which give also much less shadow. You will see their effects in future videos.
nice and also please explain the choke also for led
Sorry, but I do not understand what you want. Can you be more precise?
Andreas Spiess I want explanation of AC to DC conversion in this LED light
Haha. Die lahmen Schweizer. Grüße aus D.
:-)
No its not ripe for recycling, you got your self a free 50 watter.....
+saturn5tony As I wrote below, probably something in the manufacturing process went wrong and because it is only one chip, the other side could contain the same error and blow up a little later. So, for experiments, this is certainly still usable and I will keep it in my desk!
+saturn5tony I did not expect so many people helping a half dead LED ;-) Now I am convinced and I try to give the LED a second live.
Missed opportunity for this video's title "How many engineers does it take to change a light led ?"
Oh and BTW, check out the 50W driveless LED chips on ebay. 1.84$USD delivered, connects directly to mains power and includes over temp protection !
+shodanxx lol. I did not know they exist. But the prices vary a lot. Are there quality differences. I ask, because I had to change a few more since this video...
Thanks for your links! O ordered a few to look at them.
They flicker. No problem for outside lights but a huge headache on your workbench.
