led strip wiring

[Gast]

Hi, my current setup will have a lot of led strips (of approx 5 meter). I'll be using 24V due to lower current (and thus heat dissipation). I was wondering :

- led strips are about 5 meter long. I need parts which need at least 10 meter of led strip. Hooking up 2 x 5 meter will probably not deliver the best lightning scene? I believe the best result will probably be by attaching the second strip to a seperate 24V power supply and also drive it seperately by using a DMX driver in the cabinet?
- problem arising now is, second strip will start some 5 to 7 meters from the central cabinet... I read different opinions of how long the distance between the power supply and the start of the led strip can be? 5 meter? 10 meter?
- what kind of wiring is used to hook up the led strip? Standard 1.5 mm wiring? Of cat 7 (which is substantially narrower, i believe 0.56 mm)?
- i also read you need to power the led strips from both sides?

Anyone having personal experience?

Thx!

You should power both 5m strips from the middle! So you have exactly the same cable length and the same starting power for the case that it gets darker to the end of the strip.

Good ones don't need to be feeded from both sides.

Kind of wiring depends on the power consumption. How many watts per meter do you have?

BTW: if your driver has enough power you can use it for both! You should not exceed 5m because of the little copper on the strip whichs leads to a significant voltage drop to the end of the strip.

Approx 90 Watt for the complete strip. So 90 / 5 = 18 Watts per meter.

For 7m with 90 Watts 1.5mm is needed!

I install LED strips for a living. So have some experience in this area. You don't say if you are using RGB, single colour or RGBW strips.
Why not buy a 10m strip.
Firstly what are the specs of the strips. Is it 14W/m.
Once you know this you can work out the size of the power supply needed then add 10% to 15% on top to allow for voltage drops. Then select a suitable cable size. Powering both ends of the strip is a good idea for anything over 5m, this prevents the tail end from being slightly dimmer.
With the DMX RGBW you get 2.1A per channel if this is not enough then you can use special LED signal amplifiers and a suitable power supply. You connect the output from the Loxone RGBW module and connect it to the amplifier, depending on the type of amplifier you can get up to 6A per channel.
You can also daisy chain the amplifiers so that one Loxone RGBW controller can control any number of strips.
Our largest install to date was controlling 60m of strip max single length was 10m with one controller and lots of amplifiers.

Where can you buy good quality bright white 10m LED strips in Germany? Any suggestions? I need to do an installation of around 20meters.

I bought some stripes for testing here, very good quality and data as advertised.
