Up to this year, there have been more than 4,000 directly related LED enterprises in China, employing about 500,000 people, with an annual output of more than 40 billion LED devices and a market size of more than 30 billion yuan. However, a series of impressive figures cannot hide the lack of technology in China's LED industry.

Currently, there are more than 2,000 LED packaging enterprises in China, and the number of new LED application products launched by all domestic enterprises is less than 530, which are basically in the stage of copying and imitating each other.

Lack of core technology, high performance and high quality upstream products; Lack of principle patent, vulnerable to patent blockade, export restrictions. Domestic LED should establish LED research and development platform and patent pool as soon as possible, introduce domestic and foreign technical talents, let more technical talents into the LED industry.

Last year, the state has launched 'ten cities ten thousand' LED energy conservation plan, the first batch of 21 cities have been included in the national support plan, now 42 cities have been included in the plan. However, at present, we know from many LED enterprises that apart from the gradual popularization of LED lighting for decoration, the majority of LED lighting applications are still limited to government energy-saving projects. The key to this dilemma is that LED lighting products are too expensive.

Therefore, domestic LED enterprises should improve their own technology and build their own patent defense system as soon as possible.
