Seoul Viosys 365nm for good quality uv solution OEM&ODM service
Product Details Description
The Seoul Viosys CUN6GF1A is a high power Seoul Viosys 365nm UV LED designed for professional UV-A applications that require compact size, wide beam coverage, and strong radiant output. With 1400mW radiant power, 3.7V voltage, 1000mA current, and a 115° view angle, it is suitable for manufacturers developing UV curing tools, printing systems, coating equipment, UV torch products, inspection lamps, and custom UV LED modules.
This Seoul Viosys 365nm LED belongs to the CA3535 near-UV LED series. It incorporates a state-of-the-art SMD design and low thermal resistant material, making it practical for PCB-mounted UV light engines. The 3.5 x 3.5 x 1.1mm size gives engineers a slim package option when the product design needs strong UV output without a tall dome structure.
The 365nm wavelength is widely used for fluorescence response, UV-A curing, detection, and inspection applications. Compared with longer UVA wavelengths such as 395nm, 365nm often provides stronger fluorescence reaction with less visible purple interference in many inspection tasks. This makes the CUN6GF1A suitable for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, and UV torch products.
For production applications, this Seoul Viosys 365nm UV LED can be integrated into UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the material responds to 365nm UV-A energy. Final performance depends on material chemistry, exposure distance, optical layout, driver current, heat dissipation, and required UV dose.
The 115° viewing angle provides broad UV distribution. This makes the CUN6GF1A different from narrow-beam UV LEDs that concentrate output into a smaller spot. It is useful for applications that need wider local exposure, such as curing panels, printing paths, inspection surfaces, fluorescence areas, and broad-beam UV flashlight modules.
For OEM and ODM projects, the CUN6GF1A can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB can be used for many standard UV module designs, while copper PCB can be selected when stronger heat transfer is required. The LED can be supplied as a component or assembled into UV flashlight heads, curing modules, inspection lamps, and customized UV LED products.
Thermal design is important for this 1000mA UV LED. To support stable radiant output and long-term operation, use a suitable constant-current driver, proper soldering process, suitable PCB material, and enough heat dissipation. Engineers should verify board temperature, radiant output, beam coverage, and application performance inside the final product before mass production.
This product is a UV LED component, not a complete finished lamp. A finished product should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN6GF1A is a Seoul Viosys 365nm UVA source, not a UVC sterilization LED, and should not be promoted for disinfection or germicidal applications.
Do not look directly at the operating UV LED, and avoid unnecessary skin or eye exposure. Use protective eyewear, shielding, warning labels, and safe working procedures during testing, assembly, and operation.
