Voltage drop or ‘volt drop’ happens in all kinds of electrical installations. When larger power cables are installed more complicated calculations should 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 happens when the LEDs are positioned too far out of the power source or when longer individual runs (or lines) are attempted. This takes place because not enough power or electrical current reaches the LEDs, as it has further traveling. This leads to the voltage to decline or drop towards the end from the run.
Voltage drops out approximately .6V every metre and it is less noticeable with 24V strips. When utilizing 12V strips, a 2-3V drop more than a 5 metre run would reduce the voltage by 25% subsequently lowering the lumen (brightness) by way of a similar percentage.
Volt drop may be compared to a person climbing a mountain, the greater the altitude, the thinner the oxygen becomes as well as the less the person can breathe.
The LEDs at the beginning of the fishing line will appear bright at 100% output but the LEDs towards the end from the line will begin to fade. The brightness will reduce exponentially; the further away it gets from the source of energy. Potentially the lighting output might be reduced to % if greater distances were incorrectly attempted and cause permanent harm 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. If there is not enough voltage right at the end in the strip the clear white colour will turn pink towards the end from the line. It is because white colour is mixed from red, green and blue (RGB). However, the red requires less voltage than green and blue. When the strip is far from your power source, green and blue don’t get enough voltage and become weaker, whilst the red colour grows more prominent and turns white into pink.
The greater the wattage from the LED strip, the short the run should be. As an 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 can have a maximum run of 5 metres.
This does not mean you can’t install longer runs of LED strip, it merely means that you should require a different approach. Single colour strips and colour changing (referred to as RGB) strips are different because colour changing LED driver ul have to be controlled from one controller. Utilizing a higher rated power source will not repair the problem as the current continues to have to move through a long collection of LEDs and resistors, each one draining small amounts of power.
Single colour strips needs to be wired directly to the energy supply in 5 metre of 10 metre runs depending on the version of strip i.e. 30 or 60 LED which is used. Each run will be powered right from the energy supply and can be switched on or off by switching a switch or unplugging it from the mains. The ability supply is generally wired to your light switch but could be controlled by various types of controllers. The strips may then be positioned nevertheless you like, in just one long line or in a rectangle shape for instance. Once the strips are positioned alongside one another the light can look seamless, such as a fluorescent tube. The run could be over 100 metres hapmys length as long as the ability supply was rated appropriately.
Volt drop will occur slightly in the connecting power cables but as there are no LEDs or resisters etc draining the present, the volt drop will likely be barley noticeable. Thicker cables can be used to reach further distances.
For extended runs of colour changing strip, you have to fit amplifiers every 5 or 10 metres. Amplifiers enable the strips to become powered indirectly from the power source but in addition allow the signal from the controller to pass through through the entire run of strips. By doing this once you turn the color to red for example, everything turns to red simultaneously. The amplifiers power the strip, the power supply powers the amplifiers. Amplifiers could even be powered using their own separate power supply and you can have as many power supplies as you like on the same run. The energy supplies can be positioned nearer to the LED strip connection or wherever is most accessible.
For longer, more complex runs we can supply our customers making use of their own simple to follow wiring diagram. The diagram illustrates just how the power supply, strips and cables are connected together. As part for your LED Strip Fit brand, LED Constant voltage drivers can be supplied towards the exact lengths required; everything aside from the larger hard wired power supplies can be connected to each, requiring no tools or electrical knowledge.
