Hi Everyone,
I have an COB (chip on board) LED project for a grow room light and could really do with your help in designing the circuit as I am pretty hopeless.
I am trying to achieve a single plug into the wall solution.

The Led is a 220v x 150W rectangular strip, with live and neutral solder pads, earth is attached to the heat sink plate this strip is screwed to.
To achieve the required chip cooling I plan to make a water cooled heat sink. I realize I can buy an off the shelf solution but where`s the fun in that.
I have a load of parts at home I want to utilize. For example I have some nice 110v fans and a 24v water pump, all I need is a radiator to complete the cooling circuit. I can make my own heat sink plate for the cooled water.
So can you come up with an electrical circuit to use this mish mash of parts ?
A single wall socket must power the 220v cob led, the 110v ac fan and the 24v dc fan. Am I crazy ?

thanks

 

Am I crazy ?

Yes. At 150 watts you don't need all that much to cool it. Definitely not liquid cooling that requires a circulator pump either.

 

Well that`s great. Perhaps I could put 3 or 4 of them on a single heat sink.
Also consider, these lights stay on for 18 hrs a day.

 

II am sorry to note that LEDs connected directly to the mains is a restricted topic on this forum and may not be discussed. You can get good quality help from some of the same people at Electro-Tech-Online.

I wish you good luck with your project.
