Signs are an important part of road safety facilities and play an important role in driving. At present, many traffic signs used on highways at all levels in China adopt traditional reflective film manufacturing technology, which relies too much on high beam at night and is unclear in rainy and foggy weather.

In order to solve the shortage of traditional traffic signs, Nanjing Saikang Traffic Safety Technology Co., Ltd. set up a technical working group of active luminous traffic signs. Through a lot of experiments and analysis, it has successively completed the research on visual integration of luminous pixels of active luminous road traffic signs, the research on remote intelligent information system based on Internet of Things technology, and the analysis of solar pressure drop. Analytical voltage output optical control device and method research "and other topics.

20 13 1 1, the working group will? The draft of the national standard "LED Active Luminous Road Traffic Signs" was officially promulgated and implemented on 20 15. What is the national standard number GB/T? 3 1446—20 15。 The luminous signboard of Saikang Jiaoan is a good choice in the industry.
