The urgent need for health protection in car cabins highlights UVC LED as the preferred sterilization technology
As cars gradually become the "third living space", enclosed cabins that are used for more than 2.5 hours a day are facing severe microbial pollution challenges. Data shows that the bacterial density on high-frequency contact surfaces such as the steering wheel and central control screen in the car can reach more than 5 times that of a toilet seat. After long-term use of the air conditioning system, the microbial concentration can increase by 300%. In the post pandemic era, consumers' attention to in car biosafety has significantly increased, and a healthy cabin has become a core consideration when purchasing a car
Youweixin UVC LED technology precisely destroys microbial DNA/RNA structures in the 265-280nm deep ultraviolet band, achieving an instantaneous sterilization rate of up to 99.9% against dozens of pathogens such as H3N2 influenza virus and Escherichia coli. Compared to traditional chemical disinfection methods, its advantages of no residue, 20000 hour long lifespan, and low power consumption make it the preferred solution for a healthy car cabin. Complete the air circulation sterilization of the entire vehicle in 15 minutes, and use automated start stop technology to achieve "clean on board". It has been favored by many car companies such as BYD and Chery and has become a standard for automotive brands
Breakthrough in core technology, building a benchmark for automotive grade application scenarios technology
As one of the most stringent reliability standards in the field of automotive electronic components, AEC-Q102 certification covers rigorous testing conditions such as thermal shock at temperatures ranging from -40 ℃ to 100 ℃, live aging at high temperatures of 100 ℃, live aging in double 85 humid and hot environments, H2S/SO2/NO2/Cl2 corrosive gas testing, and 8000V discharge testing, ensuring stable operation of components under complex operating conditions for more than 10 years. With its core technology, Youweixin not only meets standards, but also achieves multiple breakthroughs
01. Full band chip design capability, breaking through the barrier of wavelength accuracy control
The independently developed MOCVD epitaxial growth process enables UVC LED chips to achieve optical power of up to 150mW@350mA Far exceeding the industry average level. By designing the epitaxial crystal structure, precise output of chips with any wavelength of 260-340nm can be achieved. Combined with a fully automatic sorting system and optical simulation design, the wavelength deviation of the integrated light source can be controlled within ± 1nm (industry standard ± 5nm), and the uniformity of ultraviolet irradiation energy can be greater than 95%. The stability of sterilization efficiency under different operating conditions is guaranteed at the chip level
02. Scene based opto mechatronics collaboration, defining three core application paradigms
Embedded disinfection and sterilization module of air conditioning system: aiming at the complex flow field in the air duct of automobile air conditioning, through the coupling analysis of optical simulation and CFD fluid mechanics, a low turbulence structure is developed. While ensuring that the air volume attenuation of air conditioning is less than 5%, the ultraviolet radiation intensity in the air duct is ≥ 2mJ/cm ², and the sterilization rate of circulating air is 99.9%. Adapting to various air conditioning system layouts, becoming the preferred choice for high-end models of mainstream car companies
Intelligent bacteriostasis scheme for vehicle mounted refrigerator: innovative integrated dynamic power adjustment algorithm can automatically adjust the ultraviolet disinfection and sterilization dose according to the refrigerator load, and accurately control the disinfection and sterilization intensity. While ensuring the food level bacteriostasis effect, it can save 40% energy compared with the traditional scheme, perfectly adapting to the strict requirements of electric vehicles for low power consumption
The dynamic disinfection and sterilization system for the cabin surface: the flexible UV light source packaging technology is used to develop curvature adaptive disinfection and sterilization modules for high-frequency contact areas such as the steering wheel and the central control screen. The active protection mode of "disinfection and sterilization when people leave" is achieved through the human presence sensing technology. The surface bacteria removal rate reaches 99.9%, filling the disinfection and sterilization technology gap in the dynamic scene
03. High reliability packaging technology, breaking through the adaptability limit of automotive grade environments
By using aluminum nitride ceramic substrate packaging technology and optimizing the stress distribution of bonding wires through finite element analysis, the fatigue resistance of solder joints is improved by 60%. By using our proprietary patented technology for airtight packaging and our exclusive UVC chip technology that can withstand high temperature and high humidity environments, the lamp beads have passed 1000 hours of 85 ℃/85% RH wet and hot live aging testing with zero failure and a protection level of IP67. At the same time, this airtight packaging technology can also pass automotive salt spray testing, ensuring that the components can operate stably for more than 10 years in various extreme environments, and the technical parameters fully exceed AEC-Q102 certification requirements
From technological leadership to ecological construction, ushering in a new era of automotive health technology
This certification marks the re establishment of scene definition rights for Chinese enterprises in the field of automotive grade UVC LED. The Uwai Core technology solution has achieved deep integration with the on-board ECU system of mainstream vehicle enterprises, supported the upgrading of OTA remote disinfection and sterilization strategy, and promoted the evolution of the health cockpit from a single hardware configuration to an intelligent protection system. According to industry predictions, the global penetration rate of UVC sterilization modules in new cars is expected to exceed 30% by 2025, and the penetration rate in the new energy vehicle market is expected to reach over 50%, forming a sub market of billions
As the only domestic supplier with the full industrial chain technology capability of UV LED, Youweixin is accelerating the layout of the collaborative disinfection and sterilization program of UVC LED and photocatalyst, developing customized modules for shared travel, high-end MPV and other subdivision scenarios, and promoting the upgrading of UVC LED technology from "functional modules" to "health and ecological core components". In the future, the company will rely on the dual quality systems of ISO 9001 and IATF 16949 to build a full lifecycle traceability system covering chip design, process control, and terminal applications, providing safer and more reliable automotive grade health solutions for global automakers
