Taiwan's Executive Yuan New Energy trillion yuan (NT) industrial plan was finalized on April 23, following the LED light traffic lights, LED street lights will be the focus of development in the next three years, there will be 1.28 million street lights replaced Among them, Suihong and Yujingguang have already succeeded in card slots, and Delta has also sharpened its knives. It is expected to fully attack the LED streetlights of NT$15 billion (the same, NT).
The Executive Yuan will ignite the third fire of emerging industries for the new energy industry today. In addition to continuing to replace 700,000 traffic lights, it will also replace 1.28 million street lamps nationwide; LED industry estimates that if the street lights average 1.1 Calculated to 10,000 yuan, the output value is more than 15 billion yuan.
Insiders analyzed that such a huge business opportunity, not only the LED factory, including power, heat, semiconductor and other companies are also actively involved in the LED street light supply chain.
For example, Delta has invested in companies such as Edison and Accumulation, and vertically integrated in the LED industry chain. The director of Delta Electronics said that in addition to attacking the business opportunities of LED street lights in Taiwan, it also launched a global layout to fully attack LEDs. Streetlight market opportunities; Kangshu uses power line communication (PLC), combined with LED street lights to launch intelligent solutions, not only power monitoring, but also remote monitoring.
It is understood that LED street light business opportunities have been launched in various county and city governments, LED packaging factory Yu Hong and optical components factory Yu Jingguang is the first to get into the ticket manufacturers. Sui Hong’s associate Wang Biyu said that Qi Hong has won four cases, including Fengyuan and Chiayi in Chitung Taichung, and will be more active in the second half of the year.
Wang Biyu said that at present, in the LED streetlights, about 20 million to 30 million yuan of tenders are inspected every month. It is expected that LED street lights can account for about 10% of the revenue this year. In the lighting system, Qi Hong uses the LED chip of the crystal electric power, the super heat dissipation module, and the accumulated driving IC. In addition, Shunhong has successively won orders for LED street lights in South China.
The first anniversary of the 512 earthquake, the lighting company has never stopped the Ministry of Science and Technology: What is the application of the Ten Cities and Wanhao Semiconductor Application Engineering?

A vector inverter, also known as a variable frequency drive (VFD) or adjustable speed drive (ASD), is an advanced power electronic device used to convert direct current (DC) power into alternating current (AC) power. It operates by employing complex control algorithms and sophisticated power electronics to regulate the frequency, voltage, and phase of the AC output waveform.
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.
