Seoul Viosys CUN26B1B Professional 365nm High-Power UVA LED for Industrial Curing

Product Details

Seoul Viosys CUN26B1B Professional 365nm High-Power UVA LED for Industrial Curing. The Seoul Viosys CUN26B1B is a high-performance ultraviolet (UVA) emitter engineered for demanding industrial and commercial applications. Operating at a peak wavelength of 365nm, this LED utilizes the patented Violeds® technology to deliver intense radiant power within a compact 3.5 x 3.5 mm ceramic footprint. It is the primary component for manufacturers of UV curing systems, counterfeit detection devices, and precision forensic instruments.

For LED module manufacturers and system integrators, the CUN26B1B solves the industry's biggest challenge with UV LEDs: degradation. By employing a specialized inorganic encapsulation process, Seoul Viosys has eliminated the use of organic materials that yellow or crack under high-energy UVA exposure, ensuring the optical output remains stable over the device's entire operational lifespan.

Key Technical Advantages for Manufacturers

• Superior Radiant Flux Density: Delivering up to 1400mW of radiant power at 500mA, the CUN26B1B allows for faster curing cycles in industrial printing and coating lines, directly improving throughput for your end-users.
• Inorganic Packaging Reliability: The combination of a ceramic substrate and glass/inorganic lens ensures that the UV energy does not damage the LED's own package. This is a critical factor for fixture manufacturers who must provide 10,000+ hour warranties on professional equipment.
• Thermal Management Efficiency: With an optimized thermal path, this component allows for high-density PCB layouts. For contract manufacturers (EMS), this simplifies the cooling requirements and reduces the overall size of the heat sink module.
• Standard 3535 Footprint: The industry-standard dimensions make the CUN26B1B a drop-in upgrade for older UVA designs, enabling a seamless transition to higher power bins without redesigning existing MCPCB layouts.

Targeted Industrial Applications

• Industrial UV Curing: Rapid drying of adhesives, coatings, and inks in high-speed printing.
• Non-Destructive Testing (NDT): Fluorescence-based crack and leak detection in aerospace and automotive sectors.
• Forensic & Counterfeit Detection: Precision 365nm light for verifying currency, documents, and biological evidence.
• Medical & Beauty: Professional UV-gel curing systems for dental and cosmetic applications.
