Seoul Viosys uv led 385nm CUN86A1G
Product Details Description
The Seoul Viosys CUN86A1G is a high power Seoul Viosys UV LED developed for professional 385nm UV-A applications that require strong radiant output, wide beam coverage, and compact SMD integration. With 385nm wavelength, 2150mW radiant power, 3.6V voltage, 1000mA current, and a 120° view angle, it is suitable for manufacturers developing UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This Seoul Viosys UV LED belongs to the Z5 near-UV LED family. It is designed for high current operation and high power output applications, using a compact 3.5 x 3.5 x 2.0mm SMD package. The structure helps product engineers create high-output UV systems without using bulky traditional lamp sources.
The 385nm wavelength is commonly selected for UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection, and oil leak detection. Compared with 365nm UV LEDs, 385nm usually produces more visible violet output, which can help visual alignment and UV-reactive inspection while still delivering useful UV-A energy.
For production applications, this Seoul Viosys UV LED can be integrated into UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the target material responds to 385nm UV-A output. Final performance depends on material chemistry, exposure distance, driver current, optical design, PCB material, thermal structure, and required UV dose.
The 120° viewing angle makes the CUN86A1G suitable for wider working areas. It is different from narrow-beam UV LEDs that focus energy into a smaller spot. This wide-beam profile is useful for curing panels, printing paths, fluorescence fields, UV-reactive inspection, broad illumination modules, and wide-angle UV flashlight designs.
For OEM and ODM projects, the CUN86A1G can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is suitable for many standard UV module designs, while copper PCB can be selected when stronger thermal transfer is required. The LED can be supplied as a component or assembled into UV flashlight modules, curing modules, inspection lamps, and other customized UV LED products.
Thermal design is important for a 1000mA UV LED. To support stable radiant output and long-term performance, use a suitable constant-current driver, proper soldering process, appropriate PCB material, and sufficient heat dissipation. Engineers should verify board temperature, radiant output, beam distribution, and application performance inside the final product before mass production.
This product is a UV LED component, not a complete finished lamp. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN86A1G is a 385nm UVA light 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.
