In the field of intelligent transportation security monitoring and supplementary lighting, supplementary lighting technology has always been a key link in ensuring imaging quality. Recently, Hangzhou Fangqian Technology Co., Ltd. again led the industry development with technological innovation, and successfully obtained two invention patents authorized by the China National Intellectual Property Administration: "an adaptive detection circuit for the trigger signal of the illminator" (patent number: 2020101601097) and "an integrated control circuit for LED strobe and flash" (patent number: 2025102298475). The acquisition of these two patents not only demonstrated Fangqian Technology's profound accumulation in the field of optoelectronic technology, but also solved the long-standing technical pain points for the industry, and raised the performance and reliability of the fill light equipment to a new height. 

Breaking through compatibility bottleneck: Adaptive detection circuit realizes intelligent recognition of all signal types

In the field of professional photography, the synchronous triggering of illuminator and cameras has always been a key factor affecting the imaging effect. Traditional illuminators can often only adapt to specific types of trigger signals (such as switch or level signals), resulting in poor compatibility between devices, complex installation and debugging, and seriously affecting engineering efficiency. In response to the pain points in this industry, Fangqian Technology's development of an adaptive detection circuit for the trigger signal of a illuminator provides a revolutionary solution. The invention of this technology makes our adaptive detection circuit like the "smart ear" of a illuminator, able to understand all camera "languages". This technology will completely change the compatibility issues caused by signal mismatch in the past, bringing unprecedented convenience to users. 

Dual improvement of performance and efficiency: integrated control technology for strobe and flash

In the field of professional photography, especially security monitoring, LED strobe (continuous fill light synchronized with the camera frame rate) and burst flash (high-intensity fill light capturing moments) are two basic but technically different fill light modes. Traditional solutions often require two independent circuit systems, resulting in large device size, high cost, and limited response speed. The second newly added invention patent of Fangqian Technology, "an integrated control circuit for LED flicker and burst," has successfully overcome this technical problem. It is worth mentioning that the technology also innovatively adopts a two-level control strategy of "overall frequency+local duty cycle". In flicker or burst mode, the MCU not only sets the overall frequency and duty cycle to control the on-off rhythm, but also generates higher frequency local PWM signals during each effective time period, and achieves fine adjustment of brightness by fine-tuning the local duty cycle. This innovative method greatly expands the brightness adjustment range and accuracy of fill lights, meeting the imaging needs in different scenarios. 

Actively promoting the implementation of technology and committed to the innovative transformation from patents to products 

As a national high-tech enterprise and a key supported "specialized, refined, unique, and new" small and medium-sized enterprise in Zhejiang Province, Fangqian Technology has always adhered to the innovative path of "research and development driven, patent protection, and product landing", and is committed to building the "first brand of security monitoring and supplementary lighting". The company focuses on research and innovation in the fields of optoelectronic technology and intelligent security, and has obtained certification from the Hangzhou Enterprise Technology Center and the Hangzhou High tech Enterprise R&D Center. As of now, Fangqian Technology has 14 invention patents, 5 utility model patents, and 1 appearance patent. At the same time, the company actively engages in external industry university research cooperation, successfully carrying out deep industry university research cooperation with higher education institutions such as Hefei University of Technology, China University of Metrology, and Hangzhou University of Electronic Science and Technology, transforming research and development achievements into practical applications, demonstrating strong technical strength and market competitiveness. 
All patented technologies of the company are developed around core product technologies and have been successfully applied in the latest generation of intelligent fill light product series of Fangqian Technology, including specialized equipment such as road monitoring fill lights and security camera auxiliary light sources. Feedback from practical applications in the high-capacity market has shown that the use of new technology in fill light devices has significantly improved compatibility, response speed, and light intensity stability, making them particularly suitable for applications such as intelligent transportation, urban security, and road control that require strict fill light performance. 
Innovation is the eternal driving force for enterprise development, and patents are the best proof of technological strength. The acquisition of two invention patents by Fangqian Technology not only consolidates its leading position in the field of professional fill light technology, but also injects new momentum into the development of the entire industry. In the future, Fangqian Technology plans to further expand its new patented technology to a wider range of application areas, including emerging markets such as automotive assisted driving, drone aerial photography, medical imaging, etc., to provide high-performance and high reliability professional lighting solutions for more industries. Under the guidance of the "Made in China 2025" strategy, Fangqian Technology will continue to uphold the spirit of innovation, promote industrial upgrading with more breakthrough technologies, and provide higher quality optoelectronic products and services to global use
