Here are three important things to note about the special customization of LED strips
1. The cutting position of the LED strip
In general, LED strips are a cut position for each group.
2. Circuit design of LED strip
The circuit of the LED strip includes a series circuit and a parallel circuit and it is a series-parallel circuit.
The advantage of the series circuit is that the current is constant and it is easier to control the drive current of the LED. The disadvantage is that if one of the LED is damaged, all of the LED will not light, but will not affect the life of the other LED.
The advantage of a parallel circuit is that any one LED is broken and does not affect the use of other LED. The disadvantage is that if no current limiting resistor is added, any LED will be damaged, which will cause the current of other LED to increase, which will burn out other LED. The series-parallel circuit is a common circuit for LED lamps, because several LED are connected in series to form a group, and then connected in parallel with other groups. It can maximize the use of the supply voltage and reduce the useless power loss. At the same time, using several LED in series can ensure that the driving current of these LED is consistent, which is beneficial to the constant LED current to ensure the service life of the LED.
3. The number of beads of LED strips per meter
Usually, the number of beads per meter of LED strips is fixed. When making a special lamp strip, the number of beads should be a multiple of the conventional lamp bead.
