How to use the LED light strip

  Here by the Shenzhen GCL Electronics Co., LTD spoke LED strip under the basic installation method and the specific specific .
   1 , how shear LED strip according to customer requirements of different groups to do a cutting position . However, some customers require a single LED as a cutting position , so that is unreasonable. Because in that case would be tantamount to a parallel circuit , the LED lights with life is no guarantee 
  2.LED light of the specific number .
   LED strip LED quantity per meter is fixed. For example 1210 is 60 lights, 30 lights is 5050 , a special 60 lights. If there are other special requirements , such as 50 lights per meter , which involves you want to modify the circuit . It is usually the 3 LED group , if it is , then the lamp 50 , a number of groups becomes insufficient , but if it becomes a set of two LED , it will increase the current-limiting resistor , this will cause a waste of resources . So, in doing special requirements of the LED light bar , be sure to pay attention to the number of lamp beads is a multiple of 3 , so as not to cause voltage waste of resources.

  3 , the circuit design of the LED strip .

  LED lights are in series, parallel , and series-parallel connection of several methods .
   1 has the advantage of a parallel circuit of any one LED does not affect the bad use of other LED . Disadvantage is that if you do not add the current limiting resistor , then any one LED is damaged , it will cause other across the LED current to increase , it will burn out the other LED. And because a single LED drive voltage is low , the voltage will cause most to do useful work , but also a waste of resource .
   2 is a constant series current circuit has the advantage , relatively easy to control the LED drive current. Disadvantage is that if one LED is damaged, all the LED will not light , but it will not affect other LED life .
   3 LED lights with universal series-parallel circuit .
    Using several LED in series with a group, and then , and other groups in parallel. You can maximize the utilization of the supply voltage , reducing wasted effort loss. Meanwhile, the use of several LED in series , can guarantee these LED drive current is the same, constant LED current beneficial to ensure that the LED life. LED lights in series group again and other groups in parallel , you can guarantee that if a group of damage to the case , will not affect the normal use of other groups . Also, because each has a current limiting resistor, so one group will not affect the other groups damage life.
    LED lights installed in two ways : Outdoor installation and indoor installation.
    Outdoor installation due will withstand wind and rain, if the use of 3M adhesive fixed, a long time will result in a decrease in the adhesion 3M LED strip off, so often used for outdoor installation slot in a fixed manner , you need to cut and connect places , methods and indoor installation the same, but need another with waterproof glue to reinforce the connection point of the waterproof effect.
   LED light strip for indoor installation without exposed to the elements , so installation is very simple . BHP Billiton to the production of LED lights , for example, each LED light strips are affixed to the back of self-adhesive 3M double-sided adhesive , can be directly installed 3M double-sided adhesive surface tear the sticker , and then the lights fixed on the need to install places, hand heal just fine. As some places require a long corner or how to do ? Very simple , LED light bar is a 3 LED is a group composed of series and parallel circuit structure, ie every three LED can cut alone .
   LED light strip for power connection is usually 12V. Requires the use of switching power supply , the power LED strip according to the size of the power and connection length to be. If you do not want each LED strip are used to control a power supply , you can buy a relatively large power switching power supply main power to do , and then put all the LED lights up in parallel with the input supply all ( wire size is not enough , then you can additionally extended ) , unified by the total switching power supply. Such benefits can be centrally controlled , convenient place can not be achieved single LED light bar lighting effects, and switch control, specifically the manner in which you can go by their own measure .
   Currently, there are some outdoor projects use 220v high voltage LED strip .
Note that if it is not time to install 220V Light Do not point directly AC220V lighting strip , do not reverse the positive and negative , the operating personnel wear an electrostatic ring operation.
Marquee and RGB LED strip lights all need to use the controller to implement Article changing effects , and each controller's control distance is not the same , in general , simple controller control distance of 10-15 meters , remote controller control distance of 15-20 meters , the longest you can control up to 30 meters . If the LED light bar connection distance is longer, and the controller can not control that long strip, then you need to use the power amplifier for the tap .
3528 series of LED lights , the connection distance up to 20 meters , 5050 series LED strip , the longest distance of 15 meters to connect . If the distance beyond this connection , the LED lights are easy to heat , the use of the process will affect the service life of LED lights . Therefore , the installation must be in accordance with the manufacturer's requirements for installation , should not allow LED lights overload operation .
