Because LED lamp beads are semiconductor devices sensitive to static electricity, static electricity can easily lead to failure of Jiangxi led unit board, it is essential antistatic ability LED display life. Generally speaking, LED lamp beads body static mode test failure voltage of not less than 2000V. With increasing brightness LED lamp usage time will gradually decay. Decay rate of LED chips, auxiliary materials, packaging technology brightness LED lamp has a certain relevance. Generally bright color led unit board, 1000 hours, 20 mA at room temperature after the lighting test, the red LED lamp beads attenuation should be less than 7%, blue, green LED lamp beads attenuation should be less than 10%. Red, green, blue Attenuation consistency of full-color LED display greatly affect the future of the white balance, and then show fidelity affect the display. Mainly for display advertising fonts (acrylic, plastic) and night effects identified it as a medium of text or logo led unit board, mounted on top of buildings or walls led unit board repair, both during the day and the effect of the performance of identity, but also use LED as light source at night showed another effect, which together with LED lighting applications, control systems, text or logo on the dynamic video control, and in some places thicker atmosphere entertainment, LED light source module has become corporate self-image shows one of the most important choices. led unit board repair, led unit board, high Jinliang photoelectric provided by Jinan High Jinliang Optoelectronics Technology Co., Ltd ..
