In the current phase, the LED industry has entered a stage of deep integration. Major enterprises are leveraging their capital strength to expand production capacity and drive down costs through large-scale manufacturing. At the same time, they are utilizing their high-quality R&D resources and strong technical capabilities to continuously enhance their soft power, further strengthening their overall competitiveness.
Among these developments, obtaining an invention patent certificate signifies a company's robust R&D capabilities and helps establish a solid patent protection network, thereby improving its resilience against intellectual property risks. Additionally, securing a high-tech enterprise certification not only reflects the company’s innovation capabilities but also brings various tax incentives that support business growth.
Recently, Hongli Zhihui announced that its subsidiary, Ledia, was granted an invention patent, marking a significant step in enhancing its intellectual property protection system. Meanwhile, Guanghao Shares and its subsidiaries have also received high-tech enterprise certifications, allowing them to continue benefiting from preferential tax policies.
**Hongli Zhihui Subsidiary Obtains Invention Patent Certificate**
On January 30, Hongli Zhihui announced that its subsidiary, Guangzhou Laidiya Lighting Co., Ltd. (Ledia), had recently been granted an invention patent by the State Intellectual Property Office. The relevant patent certificates were issued as follows:

According to Hongli Zhihui, the technology covered by the patent is one of the company's core technologies, already applied to existing products. While the acquisition of this patent will not significantly impact current operations, it strengthens the company’s intellectual property protection framework, highlights its independent R&D capabilities, and enhances its competitive edge in the market.
According to the "Monthly Monitoring Report of China's LED Lighting Products for 2017-2018" released by GGII, the total export value of LED panel lights in China reached approximately $1.784 billion in 2017, with an export volume of around 345 million units.

This indicates a vast market potential for panel lights. Ledia’s newly acquired patent on panel light design and assembly processes positions the company well to further capitalize on this growing market.
**Guanghao Shares and Subsidiaries Win High-Tech Enterprise Certification**
Recently, Xiamen Guangsheng Electronics Co., Ltd. and its wholly-owned subsidiary, Xiamen Guangsheng Display Technology Co., Ltd., were awarded the "High-tech Enterprise Certificate" by the Xiamen Science and Technology Bureau, Xiamen Municipal Finance Bureau, and the Fujian Provincial Taxation Bureaus. The details are as follows:
(1) Company Name: Xiamen Guangsheng Electronics Co., Ltd.
Certificate Number: GR201735100017
Issue Date: October 10, 2017
Validity Period: Three years
(2) Company Name: Xiamen Guangsheng Display Technology Co., Ltd.
Certificate Number: GR201735100044
Issue Date: October 10, 2017
Validity Period: Three years
This marks the company's reaccreditation after the previous certificate expired. As per national tax incentive policies for high-tech enterprises, both companies will continue to enjoy a 15% corporate income tax rate for three years following the recognition (i.e., from 2017 to 2019).

Application of low-frequency transformer:
1. Power Distribution Systems
Low-frequency transformers are essential components in power distribution systems, where they are used to step down the voltage from high-voltage transmission lines to lower voltages suitable for distribution to homes and businesses.
They ensure safe and efficient power delivery to end-users by converting high voltages to lower, more manageable levels.
2. Industrial Applications
In industrial settings, low-frequency transformers are used to power various machines, equipment, and control systems.
They provide the necessary voltage and current levels required by the industrial loads, ensuring reliable and efficient operation.
3. Audio Equipment
Audio equipment, such as amplifiers, speakers, and microphones, often employ low-frequency transformers for impedance matching and signal isolation.
These transformers help in reducing interference and noise, resulting in clearer and more accurate audio reproduction.
4. Telecommunications
In telecommunication systems, low-frequency transformers are used for signal coupling and isolation between different circuit stages.
They ensure that signals are transmitted efficiently and without distortion, maintaining the integrity of the communication link.
5. Power Supplies
Low-frequency transformers are commonly found in power supply units (PSUs) for various electronic devices, including computers, TVs, and other consumer electronics.
These transformers convert the main AC power supply to the required DC voltage levels, providing clean and stable power to the electronic components.
6. Lighting Systems
In lighting systems, low-frequency transformers are used to convert the main AC power supply to lower voltages suitable for certain types of lighting fixtures, such as incandescent lamps and low-voltage halogen lights.
They ensure safe and efficient operation of the lighting fixtures, while also allowing for more flexible lighting designs.
7. Medical Equipment
Medical equipment often requires precise and reliable power supplies to ensure accurate measurements and safe operation.
Low-frequency transformers are used in medical devices to provide the necessary voltage and current levels, ensuring that the equipment performs as intended.
8. Safety and Isolation
Low-frequency transformers provide electrical isolation between the primary and secondary circuits, enhancing safety and preventing ground loops.
This isolation feature is particularly important in applications where electrical shock hazards may exist, such as in wet environments or around exposed electrical equipment.
In summary, low-frequency transformers are versatile components that find applications in numerous sectors, where the transformation of electrical energy at low frequencies is essential. Their ability to step down voltages, provide electrical isolation, and ensure efficient power delivery makes them ideal for use in power distribution systems, industrial applications, audio equipment, telecommunications, power supplies, lighting systems, medical equipment, and safety isolation solutions.
