According to the industry, the competition in the domestic LED industry is extremely fierce, and the production cost of enterprises is high. Some enterprises have taken more efforts to make more profits in the materials, and there is a phenomenon of “scraping and reducing materialsâ€.
Another industry operator said that there are not many LED street lamp manufacturers with independent research and development capabilities in China. More manufacturers buy chips and accessories to package and sell them. Some manufacturers are prone to quality problems.
In addition, the lack of LED industry standards and specifications is also one of the factors that cause product quality problems.
