[SOLVED]"Standard" LED-Strip

[LeRooy 0]

Hello guys!

 

In which way are the most easy way to controll my LED-strip? Can I use the RGBW Controller from Fibaro to dim and in general control the light?

 

EDIT: Its a singelcolor just plane LED-strip with + and -

 

Thanks for reply gents!

Hi @LeRooy,

 

RGBW is one way to control it and device is designed to do so, but remember it is powered by 12/24V DC only. Fibaro Dimmer 2 is an alternative if you use dimable LED power supply (need to be dimmable by Voltage) and Bypass 2.

Thanks @jakub.jezek 

 

Ye the RGBW Controller needs 12/24V, but how is it wired when I just have + and - from the LED-strip when I dont have Red, Green, Blue and White wires from the LED?

[jakub.jezek 370]

@LeRooy, you connect positive (+) to 12/24V DC power supply and negative (-) to one of RGBW channels (Red, Green, Blue or White). But remember in HC to set RGBW into Output/Input, so you can control all channesl as independent dimmers, not like RGBW color mixer.

 

It is basicaly same as this:

@jakub.jezek Thanks!

 

I will try this out

 

@jakub.jezek, If I just have one switch that I want to use to turn on/off , and dimm (impuls) the LED-strip.. Do I just use one of the IN? What about the other three

Like this?

Hi @LeRooy,

 

If you want to use White output, i would recommend to connect physical button to IN4. I think Inputs are connected to Outputs.

@jakub.jezek ok, but the wiringen drawing should work like this? just connect the switch to IN4?

Hi Guys,

 

I get additional question - I would like to control 4 strips using 4 outputs and control them by one input or should I made a bridge between inputs - is it possible?

 

Piotr Br

[jakub.jezek 370]

@LeRooy, yes, wiring is correct. Just reconnect from IN1 to IN4

 

@PiotrBr, if you want to control them at once, then you can wire bridge there. Or you could create a lua scene to synchronize those outputs.

 

Lua code could look like this

Thanks for your awesome help @jakub.jezek

Hello,

 

I have a question regarding the schematics above.  If lets say i have a led strip of 15m and wire as the above will the current break my rgbw controller?

[jakub.jezek 370]

Hi @Axeman, if current is over 6A per channel, then you risk breaking the module.

[Axeman 5]

So the only solution to this is to use Led amplifier after the output of the rgbw outputs

Can anyone answer Axeman please?

I have the same question/problem...

I want to control 4 white led strips with all 4 channels....and current will probably damage RGBW controller...

Please help.

The strips come in different Watts per meter ratings so you  have to do the calculation.

Usally its wattage and voltage are written on the strip repeatedly in small writing.

So say its 5watts per meter and its a 12v strip and you have 5m so thats 25 watts which at 12v is p (watts) = V  (volts) X A (amps)Amps. 

So P/V   Is. 25/12 = 2.08 Amps

Rembering that RGBW module can do up to 6Amps per channel but a total sum of 12 amps total over the 4  . Also you cant mix power supplys so only one for everything controlled by the same RGB module including powering the module its self.

Because of volt drop which can be a real killer keep your 12v or 24v cable runs as short as possible and usally if you want long lengths of strip, break them into 5M lengths with different feed cables for each length otherwise the strip can get dim along it length.

 

Having said all this with single coloured strips it is possible to buy dimmable power supplys which you can connect directly to a dimmer 2  240 volt feed which may or may not make installation easier.

Ok lets say we place dimmable power supplys. How we will connect the Fibaro dimmer module with the wall switch we want ? And I'm asking that because in many cases the wall switch is far from the power supply and the cables in houses for the lighting circuit is 2 or 3 cables most !
