Voltage drop or ‘volt drop’ happens in all sorts of electrical installations. When larger power cables are installed more complicated calculations has to be made to counteract the problem. However when LED driver or tapes are concerned there are a few simple guidelines to follow.
Volt drop in LED strips takes place when the LEDs are positioned very far out of the source of energy or when longer individual runs (or lines) are attempted. This takes place because insufficient power or electrical current reaches the LEDs, since it has further to travel. This causes the voltage to decline or drop towards the end in the run.
Voltage drops out approximately .6V every metre and is also less noticeable with 24V strips. When utilizing 12V strips, a 2-3V drop spanning a 5 metre run would decrease the voltage by 25% subsequently reducing the lumen (brightness) by a similar percentage.
Volt drop might be in comparison to a person climbing a mountain, the higher the altitude, the thinner the oxygen becomes and the minus the person can breathe.
The LEDs at the start of the fishing line will show up bright at 100% output nevertheless the LEDs right at the end of the line will quickly fade. The brightness will reduce exponentially; the further away it gets out of the power source. Potentially the lighting output might be reduced to % if greater distances were incorrectly attempted and cause permanent injury to the LEDs.
Volt drop in single colour strips are barley noticeable, particularly in shorter lengths. Colour changing strips tend to be more visible whenever you turn the color to white. When there is insufficient voltage towards the end from the strip the clear white colour will turn pink towards the end in the line. The reason being white colour is mixed from red, green and blue (RGB). However, the red requires less voltage than green and blue. If the strip is significantly from the power supply, green and blue don’t get enough voltage and be weaker, whilst the red colour becomes more prominent and turns white into pink.
The higher the wattage of the LED strip, the short the run should be. For example; 30 LED (7.2W) per metre strip could have a maximum run of 10 metres, compared to the 60 LED (14.4W) per metre strip which could have a maximum run of 5 metres.
This does not always mean you can’t install longer runs of LED strip, it just means you need to require a different approach. Single colour strips and colour changing (called RGB) strips are different because colour changing LED driver ul must be controlled from one controller. Utilizing a higher rated power source does not fix the problem as the current still has to move through a long line of LEDs and resistors, each one of these draining small quantities of power.
Single colour strips needs to be wired directly to the energy supply in five metre of 10 metre runs depending on the version of strip i.e. 30 or 60 LED that is used. Each run will be powered right from the ability supply and may be switched on or off by switching a switch or unplugging it through the mains. The power supply is generally wired to your light switch but tend to be controlled by various types of controllers. The strips are able to be positioned however, you like, in a single long line or in a rectangle shape as an example. Once the strips are positioned alongside the other person the lighting will appear seamless, like a fluorescent tube. The run could be over 100 metres hapmys length as long as the power supply was rated appropriately.
Volt drop will occur slightly inside the connecting power cables but as there are no LEDs or resisters etc draining the current, the volt drop will likely be barley noticeable. Thicker cables can be used to reach further distances.
For prolonged runs of colour changing strip, you should fit amplifiers every 5 or 10 metres. Amplifiers allow the strips to become powered indirectly from your power source but also allow the signal through the controller to pass through through the entire run of strips. By doing this when you turn the color to red for example, everything turns to red simultaneously. The amplifiers power the strip, the energy supply powers the amplifiers. Amplifiers could even be powered using their own separate power source and you can have as much power supplies as you wish on the same run. The energy supplies could be positioned closer to the LED strip connection or wherever is most accessible.
For prolonged, more difficult runs we can supply our customers making use of their own easy to understand wiring diagram. The diagram illustrates how the power source, strips and cables are connected together. As part for our LED Strip Fit brand, LED Waterproof power supply could be supplied to the exact lengths required; everything in addition to the larger hard wired power supplies may be plugged into each, requiring no tools or electrical knowledge.
