Led remote control colour changing lighting problem

[Sonia Norman]

Hi

My son has a remote controlled colour changing led light in his room. A light blew earlier, I replaced it, but the switch wasn't working. I checked the wiring reconnected the fuse and now the lights won't turn off. It's definately wired correctly. Is there something within the relayitself that could cause it to stay live and therefore can I just replace the faulty relay switch. Its been working for the last two years so I can't think what would cause the light to stay on.

Did it blow the fuse when it first stopped working? Does this light have a plug on it or is it wired into the light switch? Can you maybe give a link to a webpage to show us the particular light you have?

Hi

Yes it did blow the fuse, I don't have the detailsof theight because I've had it so ong.The master switch, has a live and load. On the front switch are 3 buttons these are used to manualy change the colour, dimand turn on and off. Inisde the small relay greybox that has the 3 switch housing are two copper coils. My son came in ,switched the light on, it blew thefuse. I changed the bulb. And it won't turn off now.I ama very new electrician so haven't come across this yet just wondered if it could be that the relay is faulty because I am not sure why it is remaining permanently live. SorryI can't give more info.

It has probably welded the relay contacts closed with the high current of the fault in other words you will probably have to replace the control pad.... usually the fuse is quick enough to limit this happening but not in all cases... but before you spend your money ring the suppliers of the controls or ring technical support to eliminate what might be a simple reset...... if you havent altered any of the wiring then first impressions would be the relay is now duff.

It could be a relay where the contacts have welded together because of the high fault current. You can usually remove the covers from the relays if you're careful and you'll probably be able to see if the contacts are stuck together. There's also a possibility another component has been damaged. If it had a built in dimmer then a triac or diac may have blown, these can blow either open circuit or closed circuit. To be honest you'd probably be better to either replace the entire set up or buy a new RGB type controller that's compatible with the old lights.
