Shandong Province issued "Shandong Province Semiconductor Lighting Industry Development Plan (2008-2010)"

The Shandong Semiconductor Lighting Industry Development Plan (2008-2010) has recently arrived. The "Planning" proposes to take advantage of the rapid development of the global semiconductor lighting industry during the "Eleventh Five-Year Plan" period, to give play to the comparative advantages of Shandong Province in the research and development and production of semiconductor lighting industry, and to build four bases in Jinan, Weifang, Qingdao and Binzhou. Breaking through three key technologies, such as silicon carbide substrate materials and industrialization of blue-light diodes, large-scale production of high-brightness LED epitaxial wafers, high-power LED tube core manufacturing and packaging, and the development of substrates and epitaxial materials. Four industrial clusters, such as chip manufacturing, high-power light-emitting device packaging, and semiconductor lighting application products, form an internationally competitive green lighting industry with high technology level, large production scale, strong supporting capability and obvious regional characteristics.

The "Plan" proposes to provide strong guarantees and measures to strengthen the government guidance, improve the risk investment mechanism, improve the ability of innovation and industrialization, strengthen the construction of talent team, strengthen the standardization of semiconductor lighting and accelerate the development of related supporting industries. The lighting industry developed rapidly during the 11th Five-Year Plan period.

Semiconductor lighting technology is a brand-new lighting technology that uses semiconductor materials for photoelectric conversion. The products are non-polluting, energy efficient, and have significant safety and energy saving effects. Shandong semiconductor lighting technology research and industrial development started earlier. It has the State Key Laboratory of Crystal Materials of Shandong University, and has many scientific research achievements in the fields of crystal materials, semiconductor light-emitting devices, solid-state lasers, etc., Jinan, Weifang, Qingdao, Binzhou, Weihai, Jining. Yantai and other places have a good industrial clustering advantage.

Outdoor Antenna

With the rapid development of mobile communication equipment, in the mobile communications network engineering design, according to the requirements of the network coverage, traffic distribution, anti-interference requirements and network service quality and so on the actual situation to select the base station antenna, the communication base station antenna is currently on the market work the characteristics of the narrow frequency band, such as directional literal outdoor antenna, The operating frequency band is 860~960Mhz. Those multi-band antennas have the characteristics of high manufacturing cost and complex structure. With the development of communication technology, especially the popularization of 3G communication technology, such antennas are difficult to meet the market requirements. Therefore, to avoid the above problems, it is necessary to provide a base station antenna that is simple to manufacture, low cost, and reliable in performance to overcome the alleged defects in prior art.
