What are the merchants doing sunshine introducers on the market at present? What are their advantages?

At present, the manufacturers of sunshine introducers in the domestic market are Nanjing Shuairui Technology Co., Ltd., Jiangsu Shengfulai, Nanjing Jiete and Shaanxi Baoguang Optoelectronics. Japanese sunflowers are very famous abroad. Among these domestic manufacturers, Nanjing Shuairui Technology Co., Ltd. is the first company to independently develop this product. Since 2007, products have been sold in the market, and there are many engineering cases, such as Dalian Institute of Chemistry, Chinese Academy of Sciences, Beijing Information Education Center, a conference room in Wuhan, a university in Hong Kong and a corner of a restaurant in Singapore. Compared with the other three domestic companies, Nanjing Shuairui's products have their own characteristics. The others are basically based on imitating Japanese products and integrating some technologies of Shuairui. Shuairui's optical fiber is not only plastic optical fiber (also imported from abroad), but also timely optical fiber, which is currently being studied in tunnel lighting. Technically speaking, Shuairui's technology is completely mature, unlike some people who don't know, it was before 2008. Now Shuai Rui has completely solved these problems. Their strength can be seen from Shuai Rui's engineering case. Here are some pictures to look at:
