How pairing method modules LED modules in the resistance of the resistance should be configured? I believe the technical aspects of research customers and friends must have mastered the knowledge and skills together to understand. LED light module with general resistance is mainly based on the LED lamp beads with the voltage and current to set. Now lamp beads used mainly piranhas lamp beads 5050 and 3528 SMD LED module and beads. They are basically the same voltage, white led unit board, blue, green are 3.0V-3.4V, red and yellow are 1.8V-2.4V. With resistance when in Ningxia led unit board, select the median bought voltage lamp beads, lamp beads buy if marked voltage 3.0-3.2V, select voltage of 3.1V. With the continuous development of LED display industry, LED display products by the public will become increasingly familiar with, LED display diy also will become the mainstream of the entire industry. Do clear division of labor between the user and the LED display manufacturer. LED display manufacturers responsible for the development of Guangzhou led unit board, semi-finished products needed for the production of LED display and LED display module LED unit board modules, such as, the user can follow through the line like the size of any LED display DIY. LED display DIY coming era will bring the whole industry a new round of explosive growth. We often encounter LED unit board module does not light situations, packaging companies, application companies as well as units and individuals, are likely to encounter, and this is within the industry, said the phenomenon of dead lights.
