Breakthrough in UV LED Technology: Wuhan UVLEDTEK Builds a New Ecological Environment for Healthy Sterilization Industry, Leveraging the Blue Ocean of Global Billion dollar Market
Against the backdrop of the "dual carbon" strategy and global public health upgrading, Wuhan UVLEDTEK Co., Ltd. (UVLEDTEK) has become a core participant in the global semiconductor industry innovation through breakthroughs in the full industry chain technology of deep ultraviolet LED. As a national level specialized and innovative "little giant" enterprise, the company uses "light gene" technology to reconstruct the health link between people and the environment, build a vertical industrial closed loop from chip design, packaging testing to scene solutions, and promote the key leap of ultraviolet LED technology from laboratory to large-scale commercial use
Recently, at the 2025 Jiufengshan Forum and Compound Semiconductor Industry Expo, UVLEDTEK Technology showcased the latest research and development achievements of ultraviolet LED technology and its practical cases in strategic emerging industries, attracting high attention from the industry
Technological breakthrough: innovation drives efficiency leap across the entire industry chain
The core technological bottleneck of deep ultraviolet LED lies in the fact that the Wall Plug Efficiency (WPE) of the industry has long been below 7%. The root cause is the lattice mismatch between traditional sapphire substrates and aluminum nitride (AlN) films, which leads to high-density dislocations during heteroepitaxial growth and reduces the internal quantum efficiency (IQE). In addition, when the thickness of AlN film exceeds 3.5 microns, the through cracks caused by stress concentration significantly reduce the chip yield
Key technological breakthroughs
01. Nanopatterned Substrate (NPSS) Technology
UVLEDTEK Technology has achieved lateral epitaxial growth of AlN thin films by introducing NPSS technology, reducing dislocation density to one-third of traditional processes, and breaking through the film thickness to 10 microns without cracks, laying the foundation for the preparation of high-power chips
02. Optimization of Light Extraction from Moth Eye Microstructure
Drawing on the principles of bionics and utilizing photolithography and inductively coupled plasma (ICP) etching techniques, a uniform moth eye structure was prepared on the back of a sapphire substrate, which improved the deep ultraviolet light extraction efficiency (LEE) by nearly 100% and solved the photon trapping effect
03. Flexible fluororubber nanolens packaging technology
The use of gold tin eutectic flip chip, high-density COB packaging, and flexible fluororubber nanolens array deep ultraviolet LED packaging technology has solved the problem of poor device reliability and short lifespan, and developed high-power ultraviolet LED devices and light sources with high light efficiency and high light power density
Construction of Industrial Ecology: Transitioning from "Technology Following" to "Industry Leading
UVLEDTEK Technology breaks the international technological monopoly and achieves large-scale production of deep ultraviolet LED chips through vertical integration of the entire industry chain. Its independently developed DUV-LED chip WPE has exceeded 10% (compared to the international average of 7%), and its lifespan (L70) has exceeded 15000 hours, significantly better than industry standards
Facing the technological barriers of international giants, UVLEDTEK Technology has built a dual wheel drive model of "independent research and development+industry collaboration
01. Full chain production capacity layout
Establish four major R&D and production bases in Wuhan, Ezhou, Suzhou, Quanzhou and other places, independently build core equipment such as MOCVD epitaxial furnaces, chip lithography/etching equipment, and automated packaging production lines, and form a fully controllable capability from epitaxial growth to module integration
02. Construction of technical barriers
We have applied for a total of 325 patents (168 invention patents), broken through the qualification system of automotive grade reliability certification (IATF 16949), medical grade health license, ISO9001 quality management, etc., and built a three-dimensional moat covering technology, process, and quality control
03. Ecological strategic layout
UVLEDTEK proposed the "1+N" industry matrix - with deep ultraviolet chip technology as the core, horizontally expanding N application scenarios such as smart home appliances, water treatment, new energy vehicles, medical beauty, etc., and collaborating with leading enterprises such as Midea and Haier to promote the co construction of technical standards and the implementation of scenario based solutions; Vertically based on more than ten years of internationally leading AlGaN ultraviolet LED R&D accumulation and industrialization experience, it has quickly been introduced into the R&D and application market layout of emerging products, becoming a new second growth curve for the company's revenue
Application scenario expansion: from laboratory to billion dollar market
As the only high-tech enterprise in China engaged in full band and full industry chain ultraviolet semiconductor chips, UVLEDTEK Technology's core products have excellent performance and are widely used in multiple key fields with profound technological accumulation and continuous innovation
New energy vehicles: UV LED curing technology can generate insulation protective film with a voltage resistance of 3000-4000V, solving the problem of blue film breakdown resistance in 800V high-voltage batteries
5G communication: UV light source increases fiber drawing speed by 50%, reduces energy consumption by 70%, and has a lifespan of up to 30000 hours (10 times that of traditional mercury lamps)
Public health: By destroying the microbial DNA/RNA structure, it can achieve efficient disinfection and sterilization of H3N2 influenza virus, Escherichia coli, etc., replacing chlorine disinfection and ozone programs
Consumption and medical treatment: layout of air/water purification, surface disinfection and sterilization, medical beauty, plant factory lighting and other scenarios, and the market size of vehicle borne sterilization module is expected to exceed 10 billion yuan in 2030
The leap from Chinese "chip" to global "chain
As the comprehensive ban on mercury under the Minamata Convention (2026) approaches, the global market for mercury lamp alternatives worth 20 billion US dollars is accelerating, and Uweixin Technology is about to embark on a new technological journey
From the laboratory of Optics Valley to the global industrial stage, UVLEDTEK Technology weaves a healthy and sustainable future with ultraviolet light. As Chairman Professor Chen Changqing said, "We are not only manufacturing semiconductor devices, but also using the power of light to reconstruct the symbiotic relationship between humans and the environment." When ultraviolet LED becomes the core solution for global mercury lamp replacement, and when Chinese semiconductor technology establishes standard discourse power in emerging tracks, the growth trajectory of enterprises is proving the qualitative change of Chinese technology from "follower" to "ecological builder". In the national strategy of "dual carbon" and "healthy China", Uweixin is using light as a pen to draw a star sea of advanced semiconductors belonging to China
