LCD TV backlight series products and technical routes and development plans, while fully utilizing the technology of LED backlights to develop a large number of LED indoor and outdoor lighting products, to maximize the "LED application value", while Diguang actively invests and widely seeks cooperation The development of competitive upstream LED packaging and LED chip manufacturing industry to ensure the smooth supply of LED supply chain, stand out among many international professional LED LCD TV backlight manufacturers, causing the height of national governments and related science and technology departments Value and support. The company has now become a core member of the National LED Industry Alliance and is responsible for the vice president of the Guangdong and Shenzhen LED Industry Alliance. The company has provided OEM, ODM and other related services for many well-known customers and TV brand manufacturers at home and abroad.

With the aim of customer needs, the company fully supports all customers of Diguang in the rapid development of LED display, LED computer and LED TV. It can cooperate with major brands at home and abroad in joint venture, cooperation and OEM and ODM methods. Strive for maximizing the value of all parties, sharing our patents and other technologies, and maintaining the leading edge of its technology, especially our early cooperation LED customer DEO (Shenzhen Deyiyou Electronics Co., Ltd.) has entered the market in this respect. , won market consensus and continue to expand market share.

Diguang Electronics Co., Ltd. was established in 1996 and listed in the US in 2006. It has three production bases (Dongguan Diguang Electronic Technology Industrial Co., Ltd., Yangzhou Dihao Electronics Co., Ltd., Wuhan Diguang Electronics Co., Ltd.), and many higher levels at home and abroad. Universities and research institutions have long-standing cooperation. Currently, there are more than 2,500 employees. A new manufacturing base of 80,000 square meters in Shenzhen Diguang Digital Technology Industrial Park is under construction.

In 2003, the company was rated as a high-tech enterprise in Shenzhen. In 2008, it was rated as the first batch of independent innovation enterprises in the city by the Shenzhen Municipal Government. In 2009, it passed the Green Product Certification of the National Construction Association and the Shenzhen Green Brand Certification. It is one of the “2009 Top 20 Energy Saving and Environmental Protection Enterprises” in Shenzhen.

The company has obtained a number of scientific and technological achievements; in 2003, it won one Shenzhen Science and Technology Progress Award, in 2003, it completed one national key new product plan, completed one of Guangdong's key new product plans in 2004, and completed the national key scientific and technological research in 2005. In the first plan, “Intelligent Energy-saving and Environmentally-Friendly LCD/TV LED Backlight Module” won the 2008 Shenzhen Optoelectronic Display Week Innovation Design Award; the leading products of the production have been identified as national key new products and key new products of Guangdong Shengsheng City.

The company has 72 independent intellectual property rights patents, of which 32 have been authorized, 40 have been accepted; 32 invention patents, 34 utility model patents, 6 design patents; 55 domestic patents, 4 Taiwan patents, international 13 patents. The company not only pays attention to the production and quality of products, but also attaches great importance to solving the scientific and technological problems in the industry. Since January 2005, the company has undertaken 6 projects of provincial, municipal and national projects. In addition, it has also undertaken the drafting of 3 national standards. And participated in 1 international standard, 11 national standards, and drafted a number of Shenzhen local standards.

In the future development process, Emperor Optoelectronics will continue to down-to-earth, fulfill its mission, make the world brighter and better, and make our contribution to the creation of green technology and healthy living.

Fan VFD

A fan VFD, or variable frequency drive, is a specialized device utilized for controlling and regulating the speed of fan motors. By adjusting the frequency and voltage of the power supplied to the motor, the VFD enables precise control over the rotational speed of the fan. This functionality allows for efficient fan operation, improved energy savings, and enhanced performance in applications such as HVAC systems and industrial fans.

The primary benefit of a fan VFD is its ability to achieve energy efficiency. Traditional methods of controlling fan speed, such as using dampers or throttling valves, are not as efficient as a VFD. With a VFD, the fan motor operates at the optimal speed required by the system, resulting in significant energy savings. By reducing the speed of the fan when the demand is low, the VFD ensures that energy is not wasted, leading to reduced electricity consumption and lower operating costs.

Precise motor speed regulation is another advantage provided by fan VFDs. By controlling the frequency and voltage of the AC power supplied to the motor, the VFD allows for fine-tuning of the fan speed. This flexibility is beneficial in applications where varying airflow rates are required, such as in HVAC systems. The VFD enables precise adjustment of the fan speed to match the specific cooling or ventilation needs, providing optimal comfort and efficient operation.

Fan VFDs also play a crucial role in motor protection. They incorporate built-in features such as overload protection, short circuit detection, and thermal protection, which help safeguard the motor against damage due to excessive current, voltage fluctuations, or overheating. This ensures reliable motor operation, prolongs the motor's lifespan, and reduces the risk of unexpected failures.

The applications of fan VFDs are diverse, ranging from commercial and residential HVAC systems to industrial fan installations. They are employed in various settings, including office buildings, manufacturing facilities, data centers, and ventilation systems. In each application, fan VFDs offer precise control, energy efficiency, and motor protection, contributing to improved performance, reduced energy consumption, and enhanced overall system reliability.

In conclusion, fan VFDs are essential devices for controlling and regulating the speed of fan motors. With their ability to achieve energy efficiency, precise motor speed regulation, and motor protection, fan VFDs enhance the performance of HVAC systems and industrial fans, resulting in improved energy savings, optimized airflow, and reliable operation.
