LED unit board does not shine 1, check 595 is normal. 2, check the upper and lower module corresponding through foot is turned on. 3, check whether the module output pin 595 feet through. LED unit board lack of color 1, 245 RG check whether there is output data. 2, check whether the normal output of 595 feet and abnormal input pin 595 through LED lighting module designed to increase product advantages SoB import existing market of LED lighting modules in the preceding discussion also mentioned Yantai led unit board, the existing design Most still use the stand-alone module architecture design, which means that LED light-emitting part (LED light source components) and the driving portion (LED drive circuit) adopt separation design, even though a considerable number of existing industry is highly integrated LED driver circuit for the development of various The drive assembly to reduce costs caused by discrete design is too high, the more complex issues such as Liaoning line led unit board, but if still mining segment and LED light source separate from the separation of design, even if the drive assembly has significantly improved integration of discrete components Number of Ningxia led unit board, designed for the practice of the current situation is still the driving circuit and light separate design patterns, higher PCB cost and durability of the products is to add more risk. Anhui 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.
