Innovation standard development, leading the technological progress
As a pioneer in the development of China's LED industry, Guangdong Keeleng recognized the importance of the standardization strategy and in 2011 initiated the “Research and Implementation of LED Lighting Standard Optical Componentsâ€. "LED standard optical components are not a single standard, but an open dynamic standard specification system. The technical specifications mainly include interchangeability planning, quality assurance requirements and manufacturer marking indicators. It uses detailed specifications as a carrier to form a series. The chemical spectrum, the same detailed specification covers different photoelectric characteristics, but does not cover products with different mechanical size specifications.†The relevant person in charge of the Guangdong Standard Light Component Project Expert Group introduced.
In 2013, the scientific standard optical component technical specification system passed the expert review and was widely recognized by industry experts. The technical system of standard optical components has realized three first innovations: First, the new standardization and modularization method based on “light-emitting components as the reference unit†was proposed, and the standardization mode innovation was realized. Secondly, the “level project guidance book†was first proposed. The multi-unit collaborative innovation method for the main implementation content has realized the innovation of collaborative innovation method. Thirdly, the two-dimensional hierarchical grading method of “optical component†combining lighting and semiconductor industry is proposed, which realizes the innovation of hierarchical grading method. .
In this regard, Peng Wanhua, professor of the Semiconductor Lighting Standards Working Group of the Ministry of Industry and Information Technology, commented: "The LED lighting standard optical component project closely combines the urgent needs of the LED industry to promote the application of standard specifications, starting from the standardization of industrial middleware, and actively constructing the technical specifications of the hierarchical classification system. Management norms are a major innovation in the standardization path of China's LED industry."
At present, LED standard optical components have released 24 technical specifications, including the National Semiconductor Lighting Engineering R&D and Industry Alliance and some leading enterprises outside the province have also submitted proposals for standard optical components. The analysis of the industry pointed out that the formation and popularization of a batch of "factual standards" not only provide a strong guarantee for the smooth implementation of the scale application of LED lighting products in Guangdong and even the whole country, but also help to promote the core patent technology innovation with independent intellectual property rights. In order to change the international industrial structure that has been dominated by foreign major manufacturers, it will seize the right to speak internationally in the key industrial field of “industrial middlewareâ€.
Innovate the entire industry chain and promote industrial upgrading
The “Standard Optical Component Project†covers the entire industrial chain from upstream to downstream of LED lighting products. On the basis of respecting the laws of industrial development, it has innovatively realized “chain standardizationâ€. Since the implementation of the project, a large number of key basic work has been completed, and a large number of “industrial middleware†products that are mature and widely accepted by the industry have been collected for analysis. After unified patent analysis and optimization, the project has been promoted. .
At present, the standard development and system construction of LED lighting standard optical components have made significant progress. The LED lighting standard optical component R&D and application alliance has been successfully established, and has absorbed more than 150 members. More than 80% of the enterprises in the province have formed LED lighting. Initial understanding of standard light components.
Innovative promotion mode to seize the development highland
Under the support of the rigorous management system of standard optical components, in order to meet the increasing demand for standard certification testing, the LED Lighting Standard Optical Component Certification Committee and the standard optical component manufacturing enterprises with relevant laboratory qualifications jointly established the "LED lighting standard optical component testing joint. laboratory".
In this regard, the LED industry insiders evaluated that jointly establishing a joint testing laboratory with excellent enterprises is another major innovative attempt to implement collaborative innovation. On the one hand, selecting qualified laboratories can reduce investment, reduce costs, and greatly accelerate the promotion of standard optical components. On the other hand, it can make full use of the advantages of enterprise resources, so that LED lighting standard optical components can be “groundedâ€, which is beneficial to Accelerate the overall level of the LED industry and further seize the high ground of the LED industry.
Voice of the enterprise
Enhance the authority of standard optical components (Tang Guoqing, General Manager of Samsung LED China): First of all, to enhance the authority of LED lighting standard optical components, standard optical components and ZHAGA standards dock well, enabling this standard to go global and global From the industry standard to the national standard; Second, the standard optical components are practical and easy to promote. In addition, it is necessary to strengthen publicity and promotion, expand its influence and popularity, and let LED lighting standard optical components have a real status in many domestic standards.
Standardization has an indicative significance for industrial development (Lin Jiliang, general manager of the Lighting Division of Mulinsen Co., Ltd.): Mulinsen is itself a member of the standard LED component of LED lighting. We mainly conduct research on the second level of optical components. It is believed that in the future, under the organization and implementation of the Guangdong Semiconductor Lighting Industry Joint Innovation Center, the specifications of the electrical interfaces of LED lighting standards will be further unified. The active cooperation between the two sides of the LED industry and the promotion of standardization, as well as the leadership of Guangdong Province, have very important indicators for the entire industry.

Vector inverters are widely used in various industries and applications due to their ability to provide precise control over the speed and torque of AC motors. By adjusting the frequency and voltage of the AC output, vector inverters can effectively regulate the motor's rotational speed, enabling smooth acceleration, deceleration, and precise positioning. This makes them essential in applications where precise control over motor speed and torque is required, such as industrial machinery, robotics, HVAC systems, and electric vehicles.
One of the key features of vector inverters is their ability to provide vector control, also known as field-oriented control (FOC). Vector control allows for independent control of the motor's magnetizing flux and torque, resulting in improved motor performance and efficiency. By accurately adjusting the motor's magnetic field and torque components, vector inverters can minimize energy losses, reduce motor heating, and enhance overall system efficiency.
In addition to motor control, vector inverters offer a range of advanced features and protection mechanisms. They typically include built-in functions for fault detection, overcurrent protection, overvoltage protection, and thermal protection, ensuring safe and reliable operation of the system. Furthermore, many vector inverters support communication protocols such as Modbus, Ethernet, and Profibus, facilitating integration with supervisory control systems and enabling remote monitoring and control.
Vector inverters are also extensively used in renewable energy systems, such as wind turbines and solar photovoltaic (PV) systems. They play a crucial role in converting the variable DC power generated by renewable sources into stable and grid-compatible AC power. By efficiently tracking and regulating the power output, vector inverters enable optimal power harvesting from renewable sources while ensuring grid stability and compliance with grid codes.
Overall, vector inverters are versatile devices that provide precise and efficient control over AC motors, making them indispensable in a wide range of industrial, commercial, and residential applications. With their advanced features, protective mechanisms, and compatibility with renewable energy systems, vector inverters contribute to enhanced energy efficiency, improved system performance, and sustainable energy utilization.
