This achievement signifies that UVLEDTEK's UVC LED products have reached international top-level reliability and stability in the automotive electronics sector.

As a national-level specialized, refined, characteristic, and innovative "Little Giant" enterprise, UVLEDTEK has long established a rigorous quality control system covering the entire industry chain. Based on its ISO 9001 quality management system certification, the company passed the IATF 16949 international automotive industry quality management system certification in 2023. The successful acquisition of the AEC-Q102 certification further solidifies its technological leadership in core automotive electronics components.

I. The Urgent Need for Health Protection in Automotive Cockpits Makes UVC LED the Preferred Sterilization Technology

As automobiles increasingly become "third living spaces," enclosed cockpits with daily usage exceeding 2.5 hours face severe microbial contamination challenges. Data shows that the bacterial density on high-touch surfaces such as steering wheels and central control screens can be five times higher than that of toilet seats, and microbial concentrations in air conditioning systems can increase by 300% after long-term use. In the post-pandemic era, consumers' attention to in-vehicle biosecurity has significantly increased, making healthy cockpits a core consideration in car purchases.

UVLEDTEK's UVC LED technology uses the 265-280nm deep ultraviolet band to precisely disrupt the DNA/RNA structure of microorganisms, achieving an instantaneous sterilization rate of 99.9% against dozens of pathogens such as the H3N2 influenza virus and E. coli. Compared with traditional chemical disinfection solutions, its advantages of no residue, 20,000-hour ultra-long lifespan, and low power consumption make it the preferred solution for healthy automotive cockpits. It completes full-vehicle air circulation sterilization in 15 minutes and, with automated start-stop technology, ensures "cleanliness upon entry," which has gained favor from many automakers such as BYD and Chery, becoming a standard feature in automotive brands.

II. Core Technological Breakthroughs: Establishing Technical Benchmarks for Automotive-Grade Application Scenarios

The AEC-Q102 certification, one of the most stringent reliability standards in the automotive electronics component sector, covers rigorous test conditions such as temperature thermal shock from -40°C to 100°C, charged aging at 100°C, charged aging in double 85 (85°C/85% RH) 湿热 environments, H₂S/SO₂/NO₂/Cl₂ corrosive gas tests, and 8000V discharge tests, ensuring component stability over 10+ years of complex operating conditions. UVLEDTEK not only meets these standards but also achieves multiple advancements through its core technologies.

1. Full-Band Chip Design Capability: Breaking Through Wavelength Precision Control Barriers

The self-developed MOCVD epitaxial growth process enables UVC LED chips to achieve a WPE of 150mW@350mA, far exceeding industry averages. Through the design of epitaxial wafer structures, it can accurately produce chips at any wavelength between 260-340nm. Combined with an automatic sorting system and optical simulation design, it achieves integrated light achieves integrated light source wavelength deviation control within ±1nm (industry standard: ±5nm) and ultraviolet irradiance energy uniformity exceeding 95%. This ensures sterilization efficiency stability under different working conditions at the chip level.

2. Scenario-Based Opto-Mechanical-Electrical Synergy: Defining Three Core Application Paradigms

• Embedded Air Conditioning System Sterilization Module: For complex airflow fields in automotive air conditioning ducts, a low-turbulence structure was developed through optical simulation and CFD computational fluid dynamics coupling analysis. While ensuring air volume attenuation of <5%, it achieves ultraviolet irradiance intensity ≥2mJ/cm² in the duct, with a circulating air sterilization rate of 99.9%. It adapts to various air conditioning system layouts and has become the first choice for high-end models of major automakers.
• Intelligent Bacteriostatic Solution for Car Refrigerators: An innovative dynamic power adjustment algorithm is integrated to automatically adjust the ultraviolet sterilization dose according to refrigerator load, precisely controlling sterilization intensity. While ensuring food-grade bacteriostatic effects, it saves 40% energy compared to traditional solutions, perfectly adapting to the low-power requirements of electric vehicles.
• Dynamic Cockpit Surface Sterilization System: Using flexible ultraviolet light source packaging technology, curvature-adaptive sterilization modules were developed for high-touch areas such as steering wheels and central control screens. Through human presence sensing technology, it achieves an active protection mode of "sterilization when unoccupied," with a surface bacteria removal rate of 99.9%, filling the technological gap in dynamic scenario sterilization.

3. High-Reliability Packaging Process: Surpassing Automotive-Grade Environmental Adaptation Limits

The aluminum nitride ceramic substrate packaging technology optimizes the stress distribution of bonding wires through finite element analysis, increasing solder joint fatigue resistance by 60%. Through its patented hermetic packaging form and exclusive UVC chip technology resistant to high-temperature and high-humidity environments, the lamp beads passed the 1000-hour 85°C/85% RH 湿热带电老化 test with 0 failures, achieving an IP67 protection rating. This hermetic packaging technology also passes automotive salt spray tests, ensuring component stability for over 10 years in extreme environments, with technical parameters fully exceeding AEC-Q102 certification requirements.

III. From Technological Leadership to Ecosystem Construction: Opening a New Era of Automotive Health Technology

This certification marks that Chinese enterprises have reestablished scenario definition rights in the automotive-grade UVC LED field. UVLEDTEK's technical solutions have achieved deep integration with in-vehicle ECU systems of major automakers, supporting OTA remote sterilization strategy upgrades and promoting the evolution of healthy cockpits from single hardware configurations to intelligent protection systems.

As the only domestic supplier with full industry chain technical capabilities in ultraviolet LEDs, UVLEDTEK is accelerating the deployment of UVC LED and photocatalyst collaborative sterilization solutions, developing customized modules for niche scenarios such as shared mobility and high-end MPVs, and promoting the upgrading of UVC LED technology from "functional modules" to "core components of health ecosystems." In the future, the company will rely on its dual quality systems of ISO 9001 and IATF 16949 to build a full-life-cycle traceability system covering chip design, process control, and terminal applications, providing safer and more reliable automotive-grade health solutions for global automakers.
