With the recent years, LED soft light bar on the development of more and more people by the Green Mi, the application of more and more widely, at the same time, before the conventional LED soft light bar supply is not seeking, and many places and Home applications are designed to design a suitable LED soft light bar, then; LED soft light bar customization which note requirements?

First: LED soft light of the circuit design. LED soft strip of the circuit, including series circuit and parallel circuit, there is a series and parallel circuit.

Series circuit has the advantage of constant current, relatively easy to control the LED drive current. The disadvantage is that if one of the LEDs is damaged, all LEDs will light, but will not affect the life of other LEDs.

The advantage of the parallel circuit is that any LED is broken and does not affect the use of other LEDs. The disadvantage is that if no current limiting resistor, then any LED is damaged, it will cause other LED current increases at both ends, will burn other LED. And because a single LED drive voltage is very low, will cause most of the voltage to do no work, for the resources is also a waste.

Series-parallel circuit is the current LED light bar common circuit, because the use of several LED together in series to form a group, and then in parallel with other groups. Can maximize the use of the power supply voltage, reduce unwanted power loss. At the same time, using several LED series, you can ensure that these LED drive current is consistent, is conducive to constant LED current to ensure that the LED life. After the series of LED lights and then in parallel with other groups, you can ensure that if a group of damaged cases, will not affect the normal use of other groups. At the same time, since each group has a current limiting resistor, it will not affect the life of the other groups due to the damage of one of the groups.

Second: LED soft light strip of the cutting position. In general, each group makes a cut position. But some customers will require a single LED to do a cut position, this is unreasonable. Because that would be tantamount to a parallel circuit, the life of the LED light bar is no guarantee.

Third: LED soft light strip per meter of the number of beads. Normally, the number of LED beads per meter is fixed. Such as 1210 is 60 lights, 5050 is 30 lights, special is 60 lights. If there are other special requirements, such as 50 lights per meter, which involves the need to modify the circuit. Because it is usually a group of three LED, if it is 50 lights, it will become a group of not enough, but if it becomes a group of two LED, it will increase the resistance of the current limiting resistor, this will result in waste of resources The Therefore, in the special requirements of custom LED soft light when the time, we must pay attention to the number of lamp beads is a multiple of 3, so that it will not cause a waste of voltage resources.
