In recent years, LED electronic display along with the notification to carry Fuzhou led unit board, LED electronic screen application areas more widely, by virtue of the LED electronic screen brightness, high refresh rate and other advantages, quickly became a leader in the field show screen category but also precisely because of high brightness LED electronic display constituted by light pollution, often have been criticized by everyone. In order to prevent light pollution is very good led unit board, Jiangsu brightening electronic especially compiled some security for LED electronic display brightness parameter setting methods and security approach. 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 Anhui led unit board, led indoor unit board blue, green are 3.0V-3.4V, red and yellow are 1.8V-2.4V. With resistance at the time, bought the intermediate value selection voltage lamp beads, lamp beads buy if marked voltage 3.0-3.2V, select voltage of 3.1V. Ningxia led unit board _ Gao Jin photovoltaic (certified) _led unit board provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd. (www.gjlled.cn) is an industry leader in Jinan, Shandong, liquid crystal devices, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Gao Jin photoelectric leadership with the staff warmly welcome all inquiries negotiations to create high gold Photoelectric better future.
