Based in the heart of Silicon Valley, Violumas, the UV division of the Cofan Group, specializes in providing a full-service UV LED product portfolio and solutions, from UV LEDs to customized modules. Thanks to the integrated thermal structure (3-PAD) in the Flip Chip LEDs and Metal Core PCBs, Violumas' UV LEDs achieve rapid thermal dissipation and lower thermal resistance, consistently delivering high-performance products with increased optical power and reliability to meet market needs. TrendForce was honored to conduct an exclusive interview at Photonics West 2026 with Saya Han, Director of Business Development at Violumas, who showcased the company's latest product advancements and shared valuable insights into the UV LED market outlook.
Saya Han, Director of Business Development at Violumas
Han indicated that Violumas is dedicated to exploring innovative market opportunities by leveraging its strong customer support, product advantages, group resources, and extensive experience in industry-oriented customization from UV LEDs to the module business.
The market demand for UV LEDs is growing steadily across various applications, including curing, solar simulators, life sciences, bioanalysis, spectroscopy, medical technology, surface disinfection, and water sterilization. Therefore, Violumas offers 5252 UV LEDs (single chip) and 7272 UV LEDs (four chips) covering a comprehensive wavelength range of 255-405nm. Specifically, Han indicated that the 255-275nm 5252 UV LEDs with optical power ranging from 65-145mW are marking a significant milestone once again in the UV-C LED industry. In addition, in response to medical market needs, the company's 340nm 210mW UV-A LEDs have consistently attracted market attention in 2026.
Violumas has also developed 7272 UV LEDs (four chips) with beam angles of 60°, 90°, and 120° and 3×3 / 4×4 COB LEDs. Additionally, an ultra-narrow beam 10° high power UV LED covering the wavelength range of UV-A, UV-B, and UV-C is fully prepared for collimation, focused illumination, and fiber coupling applications.
To enhance customized value-added services, Violumas delivers module solutions for applications including curing, additive manufacturing, surface disinfection, and flowing water sterilization.
Han indicated that the company has several business activities scheduled for 2026, including plans to fully upgrade the 3535 UV LED product series by 2Q26. With the continuous development of high-performance UV LEDs, Violumas aims to accelerate industry adoption by providing a wide variety of products suitable for the applications mentioned above.
