Under the guidance and organization of the Ministry of Industry and Information Technology, the “China Semiconductor Lighting/LED Industry and Application Alliance†jointly sponsored by more than 150 domestic LED companies, lighting companies, industry associations, standardization organizations, and testing organizations was officially opened in Beijing on January 6. The listing was established.
Ding Wenwu, Director of the Department of Electronic Information of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology will focus on strengthening guidance and planning, accelerating the adjustment of industrial structure, strengthening the construction of standards, intellectual property rights and testing systems, as well as strengthening the upstream and downstream interaction of the industrial chain and increasing the promotion of LED in various fields. Application and other four aspects to promote the development of the LED industry.
Ding Wenwu introduced, including the use of various channels of funds, increase investment in research and development, break through key industry technologies and large production technologies; improve the quality and level of foreign investment, and encourage foreign superior enterprises to increase investment in the upstream sector of the industrial chain; Technical transformation and other means to promote technological upgrading of key enterprises, adjust product structure; strengthen integration of industrial resources, promote mergers and acquisitions of enterprises, and support enterprises to become bigger and stronger.
It is reported that after the establishment of the alliance, the main tasks include promoting independent innovation of core technologies and products in the semiconductor lighting/LED industry, and promoting the transformation of scientific and technological achievements into real productivity. In addition, it also promotes the construction of public service systems and technical standards for semiconductor lighting/LED industry.
Zhang Zhicheng, deputy director of the Department of Protection and Coordination of the State Intellectual Property Office, admitted that the semiconductor lighting/LED industry is a technology-intensive industry. One of the keys to promoting rapid industrial development, occupying high-end industrial development and controlling the initiative of development is to master high-level intellectual property rights.
Statistics show that in 2011, China's LED industry output value reached 154 billion yuan, an increase of 22%, and output increased by 50%. It is expected that in 2012, driven by lighting products, the industry's output value is expected to reach 200 billion yuan, an increase of 30%.
According to reports, since 2005, the number of patent applications in the global semiconductor lighting field has exceeded 10,000, and has maintained rapid growth. Japan and the United States have mastered most of the patented technologies. Among them, Japan has an absolute advantage, accounting for 39.8% of the total global patents; followed by the United States, accounting for 27.6%. Although China's semiconductor lighting industry started late, the industry has made rapid progress. The growth rate of patent applications has been the highest in the world in the past five years.
At present, the number of patent applications in China has accounted for 27.2% of the global total, which is close to Japan and the United States, and has become one of the most active markets for patent technology. Domestic related units have mastered a number of intellectual property rights in LED epitaxial materials, chip manufacturing, device packaging, phosphors, etc., forming a certain technical foundation. The industrial pattern of the Pearl River Delta region, the Yangtze River Delta region, the Gan region and the northern region and the seven bases of Dalian, Guangzhou, Shenzhen, Nanchang, Xiamen, Yangzhou and Shijiazhuang have also taken shape. The technological development of China's semiconductor lighting industry is showing a vigorous trend.
However, it is worth noting that there are still some issues in China's semiconductor lighting that require attention. Ding Wenwu said that China's patent portfolio with market value and strategic significance is extremely lacking.
The main function of the Solar Charge Controller is to manage the charging and discharging process between the Solar Panel and the battery in the solar power generation system. Its main function is to protect the battery from overcharge and over-discharge damage, ensure battery charging efficiency, and stabilize the operation of the solar power generation system.
Main effect:
Charge control: The solar charge controller controls the charging process by monitoring the voltage and current generated by the solar panel to ensure that the battery is charged at the appropriate voltage and current to extend the battery life.
Overcharge protection: The solar charge controller can monitor the charging status of the battery, and when the battery is fully charged, it will automatically stop charging to avoid battery damage caused by overcharging.
Over-discharge protection: The solar charge controller can monitor the discharge state of the battery. When the battery power is lower than a certain level, it will automatically stop discharging to avoid battery damage caused by over-discharge.
Differences from other charge controllers:
The solar charge controller is a charge controller specially designed for solar power generation systems, the main differences are as follows:
Applicable Energy: The solar charge controller is suitable for solar power generation systems, mainly used to manage the charging and discharging process between solar panels and batteries. While other charge controllers may be suitable for different energy generation systems, such as wind energy, hydro energy, etc.
Charging characteristics: The solar charge controller is optimized for the characteristics of the solar panel, and can control the charging process according to the output power and voltage characteristics of the solar panel. Other charge controllers may be optimized for different types of energy generation characteristics.
Protection function: Solar charge controllers usually have overcharge protection and over-discharge protection functions to ensure the safe charging and discharging of batteries. Other charge controllers may have different protection functions, depending on the needs of the application scenario.
Overall, the main role of the solar charge controller is to manage the charging and discharging process in the solar power generation system, protect the battery from damage, and stabilize the system's operation. Compared with other charge controllers, it is optimized for the characteristics of solar power generation systems and has unique functions such as overcharge protection and over-discharge protection to meet the needs of solar power generation systems.
