Wiring LED Strip Lights

June 3, 2010   

All of our LED strip is rated at 12v and therefore require the appropriate 12v LED driver (transformer) if your system is to be connected to the 240v mains supply.Our large LED drivers 45w and 150w versions are pre wired with cable tails for you to connect to, the mains supply side having three cables, positive, negative & earth. The 12v side has just two cables, positive (red) & negative (blue or black). For single colour LED strip the 12v cable is connected directly to the strip whereas the RGB Red Green Blue) colour changing strip requires the 12v to be connected to the controller unit before linking to the strip. Bear in mind the total length of LED strip required for your project along with the number of cuts, corners and general logistics as to calculating the size and number of drivers you require.Remember that the single colour LED strip operates at 5w per metre and the RGB operates at 7.2w per metre.Maximum connected continuous length of LED strip is – single colour 15m and RGB 10m.You can of course run longer lengths but you need to wire the runs separately but you can create the impression of just one continuous run of light.

FlexConnect LED Strip Wiring

When it comes to assembling LED strip systems nothing compares to FlexConnect in terms of simplicity and speed. Your whole set-up simply plugs together by hand, so does not require and tools or expertise. See the example configuration diagram above to see how it works.

- Take the jack plug output of your driver (power supply) and connect onto the inline switch/dimmer if you are using one. If not, skip to the next step. – Connect your power lead. This has a jack plug one end and a four-pin socket on the other. – Connect your strip into the power lead. – Add the rest of your strips, connecting cables and corners, simply push them together as required.- Plug the power supply into the mains and switch on!

Using FlexConnect with a Wired Driver

Running long runs of FlexConnect LED strip may require a more powerful driver than the standard 72w version supplied with our Starter Kit. The non-standard drivers utilise screw-terminals rather than a jack-plug output so require a connecting lead to link between the driver and controller. The required lead has a jack-plug on one end leading to two bare wires on the other.

To connect your upgraded driver to a FlexConnect system, connect the live and neutral mains input into the corresponding L and N screw-terminals on the driver. Then take the aforementioned connecting lead, attach the bare wired end into the -V and +V terminals (ensuring correct polarity) and plug the jack-plug into the corresponding socket on the LED controller. Connect the rest of the system together as you would a standard FlexConnect assembly using the four-pin connections.

RGB LED Strip Wiring

Wiring standard RGB LED strip (NOT FlexConnect) together requires some soldering and general DIY experience. For those not comfortable with basic electrical wiring techniques, consider using the push-fit FlexConnect LED strip or our Made to Measure service.

- As per the simple wiring diagram above. wire your mains input to the driver, connecting the live and neutral wires into the corresponding L and N on the driver input. – Connect into your RGB LED Controller using two cables, from -V and +V respectively. You will notice there are three of each of these outputs on the 200w driver, this is for multiple outputs so any will work fine. Ensure correct polarity by making sure that -V and +V are linked to the -ve and +ve respectively on the controller input. – You will need four cables to join your controller to the strip. These are +12v, R (red), G (green) and B (blue). Attach to the controller using the screw-terminals and solder the other end to the corresponding marked terminals on the strip. Connecting the output of the controller to the wrong terminal on the strip (i.e. blue to green) will result in the strip displaying different colours to those you select on the remote. – Join each piece of strip in the same way. Connect the +12v, R, G and B terminals of the two strips using four cables of your desired length. Solder into place, being careful to keep the terminals separate to avoid short-circuits.
