Many people have heard the news that LED strips need to be recharged. But do not understand why this is? Today ZBL Lighting will come to explain the relevant knowledge. We all know the LED strip, he is divided into high-voltage strip and low-voltage strip. High-voltage strips usually refer to more than 48V strips, while the more common low-voltage strips, refers to less than 36V strips.
LED strip voltage is insufficient because the voltage drop across the wire is too large, because the wire material, wire diameter when a certain, the longer the length of the wire, the greater the resistance of the wire, as can be seen by U = IR, the load current is certain, the greater the resistance of the wire, the greater the voltage drop across the wire! Therefore, we found that the front section of a strip light is very bright and the more to the back of the gradual darkening, which is the voltage drop across the strip. Therefore, in order to solve this problem, we need to make up the power to the LED strip.
Usually LED high-voltage strip because of the high voltage, so the recharge distance is longer, usually 50m or 100m before you need to recharge once.
And low-voltage LED strip, usually in about 5m need to make a replenishment operation.
1. reduce the length of the wire. r = ρL / S, ρ and S must be, the smaller the L R is smaller.
2. thicken the wire, increase the cross-sectional area of the wire. r = ρL/S, ρ and L is certain, the larger S R will be smaller.
3. choose a wire material with smaller resistivity. r=ρL/S, when L and S are certain, the smaller ρ the smaller R will be.
4. Increase the input voltage. Properly increase the input voltage can offset the voltage drop across the wire.
The above is about the knowledge of the LED replenishment explained, I hope to help you, when we pick the LED strip again, be sure to follow the instructions on the appropriate replenishment, it is not recommended to operate on their own, especially the dangerous high-voltage strip.
