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 as Beijing led module voltage, white, blue, Chengdu led module, green is 3.0V-3.4V led module, red and yellow are 1.8V-2.4V. With resistance when in Guiyang led module, select the median bought voltage lamp beads, lamp beads buy if marked voltage is 3.0-3.2V, select voltage of 3.1V. More accurate calculation method LED unit board: length × height using cell plate number plate = total number of units using the number of LED unit board such as: 5 meters long, 2 meters high P16 led monochrome display uses several modules: LED display screen long use cell plate number = 5 meters ÷ 0.256 米 = 19.53125≈20 a LED display high-use unit number plate = 2 meters ÷ 0.128 米 = 15.625≈16 a LED display uses the total number of LED unit board = 20 × 16 a = 320 Zhengzhou led module, Gao Jin photovoltaic (certified), led module provided by Jinan Optoelectronics Technology Co., Ltd.
