Last night, Mayor Xu Zongheng hosted a meeting overnight to conduct a special study on promoting the LED industry to form a cluster of high-end industries. He emphasized that successive municipal committees and municipal governments have not missed any opportunity in industrial development. What we are doing today may be a historically significant event that may support a major industry because LED is a sunrise industry with great potential. It is an industry that saves energy and reduces emissions, and is an industry that conforms to the scientific development concept. All levels and relevant departments must follow the government's support, policy guidance, scientific planning, promote agglomeration, actively invest in and promote research and development, focus on propaganda, build demonstrations, accelerate development, strengthen and expand the policy, and actively take measures to promote the LED industry. Be stronger and bigger. Xu Qin, member of the Standing Committee of the Municipal Party Committee and executive deputy mayor, and Li Ping, secretary general of the municipal government, attended the meeting.
The meeting listened to the overall situation report of the development of LED (semiconductor lighting) industry in our city, and studied how to promote the gathering of LED industry and make the industry stronger and bigger. It is reported that semiconductor lighting belongs to the new sunrise industry. Compared with traditional light sources, semiconductor lighting products have the characteristics of long service life and high luminous efficiency. The market prospect is huge. Last year, the global semiconductor lighting industry output value reached 900 billion yuan. At present, Shenzhen has become the world's major production and supply base for LED backlights, the largest production and supply base for domestic LED displays, and has become a major domestic production site in the field of packaging and special lighting. The city has more than 700 companies engaged in the research, development, production and sales of semiconductor lighting technology and products, accounting for more than one-third of the country's total, distributed in the substrate materials, epitaxy, chips, packaging, application industries and ancillary products, covering the industry. Chains in all areas. Last year, the city's LED industry reached 15 billion yuan and employed 120,000 people. Despite the rapid development, there are still many problems in the development of Shenzhen LED industry, especially the international financial crisis that is currently raging, and it has formed a big impact on the production and operation of semiconductor lighting companies in Shenzhen.
After listening to the report, Xu Zongheng said that the LED industry is a sunrise industry and a green industry, in line with the direction of scientific development, in line with the intensive and economical development path, in line with the development path of harmonious Shenzhen benefit Shenzhen, and also in line with the country's industrial development direction. For a long time, the municipal party committee and municipal government have given full attention and support to this industry and promoted the continuous development of the industry. At present, Shenzhen has formed a certain scale of industrial advantages in the LED industry, initially formed a relatively complete LED industry chain, gathered a large number of professional and technical personnel engaged in the LED industry, and has a stronger and bigger industrial development foundation, formed The favorable conditions for promoting the rapid development of the LED industry have important factors and conditions for seizing the commanding heights of the domestic and international LED industry. We must take a high look at this industry, love it, and attach great importance to it.
In promoting the development of the LED industry in our city, we must adhere to the government's support, policy guidance, scientific planning, promote agglomeration, actively invest in and promote research and development, focus on propaganda, build demonstrations, accelerate development, and strengthen the guiding ideology. After in-depth analysis of the favorable conditions for the development of the LED industry in our city, Xu Zongheng emphasized that the next step is to start from six accelerations, vigorously promote the solution to the bottleneck problem that restricts the development of the LED industry, and strengthen efforts to promote the further development of the industry:
First, we must accelerate the formulation of relevant industry support policies, and provide strong guarantees for industrial development from the policy level. Second, we must accelerate the construction of agglomeration parks. The planned LED Industrial Park in Guangming New District should speed up construction and intensify the transformation of a number of old industrial plants. To provide space for industrial development and promote the formation of industrial agglomeration; Third, we must accelerate the construction of the public platform for the LED industry, build a group of public R&D, testing platforms and public information platforms with high starting point and high standards to provide technical support and services for the development of the LED industry. Fourth, we must accelerate the construction of the trading platform for LED industry products, and form a centralized display and trading platform for LED products. Fifth, we must accelerate the demonstration project arrangement for the use of LED products by the government, and promote the application of LED industry by introducing a number of demonstration projects. Good atmosphere, form a demonstration role; Sixth, we must accelerate the development of the LED industry development planning, form a plan within one month, report to the municipal government executive meeting to discuss and approve as soon as possible, so that industry and enterprises benefit.

Processing materials mainly include optical glass, quartz, float glass, high borosilicate glass, laser crystal, sapphire, ruby, germanium glass, germanium single crystal, zinc selenide, single crystal silicon, K9 crystal glass, calcium fluoride, silicic acid Salt glass, zinc selenide and cyanide infrared glass lens.
Among them, H-K9L (N-BK7) is crystal clear and has excellent transmittance from visible to near infrared (350-2000nm). It is the most commonly used optical glass for preparing high-quality optical components. When the extra advantage of UV fused silica is not required ( When it has good transmittance and low thermal expansion coefficient in the ultraviolet band), H-K9L is generally selected for optical coating and other fields.
K9 (BK7) has excellent mechanical properties and very low bubbles and impurities, and has good scratch resistance. Due to its stable chemical properties, special grinding and polishing are not required. It is used in many fields such as optoelectronics, microwave technology, diffractive optical element and so on.
