Analysis: hidden dangers behind the rapid development of LED lighting

<

At this stage, both the domestic and global LED lighting industries are experiencing rapid growth. However, beneath this fast-paced development, China's LED industry has revealed several critical challenges, including a lack of core technological innovation, limited research capabilities, and an unregulated market environment. These issues manifest in the following ways:

First, in terms of output value, the current adoption rate of LED technology in the Chinese lighting market is only around 5%. The industry heavily relies on imported core technologies, which significantly hinders its further progress. LED chips act as the engine of any lighting system, and without advanced internal technology, the entire industry’s growth is constrained. Most of the key technologies for producing LED chips are controlled by foreign firms, and the process of localizing these technologies is slow. This delay has slowed down the overall development of the sector. For instance, MOCVD epitaxial furnaces and their supporting technologies, which are crucial to the LED supply chain, are still largely imported, limiting cost efficiency and self-sufficiency.

Second, in terms of overall technological level, China lags behind the world’s top-tier countries by about two years. Many developed and developing nations are rapidly advancing in semiconductor lighting technology. In this context, China remains in the second tier, facing stiff competition from global leaders who are continuously innovating and improving their products.

Third, the LED lighting market in China is plagued by low-quality products and a chaotic competitive landscape. Many small and medium-sized enterprises are flooding the market with substandard goods, leading to unstable product quality and consumer distrust. This situation not only harms the reputation of the industry but also makes it difficult for genuine innovators to stand out.

Fourth, as international giants expand into the Chinese market, many domestic companies with strong core competencies may face the risk of being acquired or even eliminated if they fail to keep up. Without proper regulation, the future could see Chinese manufacturers becoming mere subcontractors for foreign lighting brands, rather than independent players in the global market.

So, how can we address these industry flaws and potential risks? Experts suggest the following strategies:

First, the government should provide stronger national guidance for local LED industry planning and quickly establish comprehensive industry standards. Especially for demonstration projects such as street lights, tunnel lights, display screens, and landscape lighting, clear standards will help local governments make informed purchasing decisions and ensure quality across the board.

Second, given the intensifying market competition, it is essential to accelerate R&D efforts in next-generation semiconductor lighting technologies. Additionally, the localization of MOCVD equipment—critical for high-end production—should be prioritized. This will reduce dependency on foreign suppliers, lower costs, and promote sustainable growth in the strategic emerging industry of semiconductor lighting. Relevant policies should also be introduced promptly, along with enhanced testing institutions to improve accuracy and credibility in product evaluation.
