I have an LED lamp that I bought from IKEA 3-4 years ago. Sadly it has failed. Which bit of the thing has failed I am not sure about, but it no longer works as required.
Sadly IKEA (in their wisdom) do not make or sell the units any more. Worse than that, they do not make any unit that fits the driver/connection that this light uses. So I have a whole infrastructure behind cupboards etc that will need replacing because one lamp has failed.
So, I took to the internet and searched high and low. I found the same unit on sale from someone in the US. I bought what may be the last in the world, who knows. Anyway, I got it and hey ho I forgot the US unit will work on 110V, not 220/240V like here in Europe.
So. I have two questions. The driver will supply power to the (broken) lamp at 240V @ 2.5W. The new lamp looks like it needs power at 120V @ 2.5W.
Q1. Will the new lamp survive if I simply say sod it and connect it to the current driver, or will I fry it?
Q2. Is anyone out there competent enough to take the two apart and work out what is broken in the old unit, and perhaps take the part from the new lamp and replace to make the old one work again???
Any thoughts gratefully received.
It will certainly fry it.
I think I have a step down transformer lying around the house. Overkill for a lamp but might be useful for checking it...
I'll confirm whether we still have it shortly.
Shariq Let me know what you have got. I never did any electronics sadly, so this is not an area I know much about...
We do have a 220-240v to 110-130v step down transformer. Feel free to borrow to test to see if the lamp itself works. Though might be too expensive as a long term solution for using the lamp.
Hmm, I think this sounds a bit complicated as a solution to be honest, thanks for the help though. I might try the guys Tris mentions, unless Andrew has anything brighter than that to suggest.
Some electronic gear is designed to work on 120-240v but it should be labelled as such if that's the case. If it just says 110v it's not a good idea to try plugging it in.
If you want to get somebody to look at repairing it, the recommendation that usually comes up here is http://www.zens.tv/. Converting the 110v version could potentially be easier than repairing the failed one.
Are you sure the "driver" is putting out 240v though? If these are kitchen cupboard lights or similar, I think they are normally low voltage units (e.g. 12v) connected to the mains supply via a transformer with switch / dimmer etc. Or are they just daisy chained to the mains via a switch?
Looking at the contemporary product sheet for these, it looks like these are connected direct to the mains through a simple switched cable, so any driver / current limiting circuitry will be inside each unit.
Your best bet (if you’re reluctant to replace the system) is to take both units to somebody who knows what they are doing and can hopefully make up one that works on the right voltage.
Tris- no, they use a driver, and I believe it is the one Andrew points to below (from memory)
Have you got a bit more info about what's working, what's failed, what you've bought, what i plugs into, etc.
LED lights aren't going to be 120/240V, there's going to be a transformer and a driver in there somewhere or there may be a combined transformer/driver.
It may be that the transformer can work with a range of voltages, I'd expect a few more things on it showing input and output.
Is it one of these that you're replacing https://www.amazon.co.uk/IKEA-ANSLUTA-Electronic-transformer-White/...
Andrew. I have both the new 110V and old (broken) 240V lamp with me. The driver and working light are installed in a kitchen in France. I brought the old one home in the hope I could get a replacement.
I believe the Ansluta driver you link to is the right one. But when I try to look for the spec it is interesting to see that the output is 24V, not 240V... This one on ebay shows the driver spec when you look at the middle of the three images. I was hoping to see if the transformer did work with a range of voltages, but its not clear to me form this if it does. How do I work that out do you think?
As to what has failed, I am assuming it is the light as the other light that is linked to the same drive is still working. I am trying to remember exactly what happens, but I cannot remember. I will take it back with me and check in a coupe of weeks time.
I was really hoping the driver would work with a range of voltages,a s you mention or I could get the broken part in the lamp identified and possibly replaced...
What I linked to is the transformer, not the driver. The driver is probably bundled in with the light.
An output of 24V sounds about right for those lights.
I'm a bit confused about exactly what is and isn't being replaced.
So far as I understand you have the transformer (in your ebay link) which plugs into the mains. That has multiple lights plugged into it and one of those lights has stopped working. Is that correct?
Do you have pictures of the new and old lights? In particular any writing on them and the cables. What's the model number?
Now you see why I am asking... It is the light unit itself I am looking to replace (or one of the two as one still work and is still in situ in France), see the image posted above with info that is stuck on both lights is shown. Let me know if this is not enough/clear
