LED light strips are more more popular among consumers due to their energy-saving products, many patterns, dazzling changing effects, high brightness, suitable price, wide applicable environment, simple easy installation. In the entire industry, everyone's naming calling of full-color LED strips is uniform. The professional name is that LED full-color strips are also called LED magic color strips.

     Compared with the ordinary light bar in the market, led strip manufacturers mainly have an additional driver IC on the FPC board. At the same time, there are certain standards for the copper requirements in the board manufacturing process. Improper use of copper will cause serious product instability, so the board requirements for LED magic light strip 12V 30 lights will be more than 2A copper on the double panel.

Manufacturers of double-row LED strips with constant current: the current voltage values should be carefully used, which limits the number of LEDs used; constant current drive circuits are more ambitious to drive leds, but relatively expensive High; the constant current circuit is afraid of short circuit of the load, but it is strictly forbidden that the load is completely open; the current output by the constant current drive circuit is constant, but the output DC voltage changes within a certain range with the difference in load resistance, the load resistance is small , The output voltage is low, the larger the load resistance, the higher the output voltage.

     Short circuit: Many LED lights do light up due to short circuits at the feet. Be sure to investigate the real reason for no light before repairing. Otherwise, after the non-bright LED is changed rashly, the chip that forms the LED will be broken by short-circuit DC current when the power is re-applied. Because, before changing the new LED, we must first find the real reason that there is no bright, some of the targeted ability can do more with less.
