Effect of LED light-emitting device performance LED lighting device is the most critical and display the most relevant parts and life. For LED p10 led unit board, mainly the following indicators: attenuation characteristics, water vapor permeability, UV resistance. If the LED display manufacturer LED device performance indicators for assessment, but off led unit board p10, would be applied to the display, it will cause a lot of quality accident, seriously affecting the life of the LED display. The root cause of uneven are: inconsistency LED performance parameters; the display in the production, installation assembled lack of precision; the electrical parameters is not enough consistency to other electronic components; module, PCB design is not standardized. The "inconsistent with the performance parameters of the LED" is the main reason. These inconsistent performance parameters include: light intensity is inconsistent, the optical axis is inconsistent, inconsistent color coordinates, inconsistent color light intensity distribution curve of each group and damping characteristics inconsistent. _led unit board led unit board _ Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd.
