uva leds Seoul Viosys UV 385nm CUN86A1B
Product Details Description
The Seoul Viosys CUN86A1B is a 385nm UV-A LED designed for manufacturers that need compact UVA LEDs with wide beam coverage, strong radiant output, and reliable SMD integration. With 1200mW radiant power, 3.5V voltage, 500mA current, and a 120° view angle, it is suitable for uv curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This model is part of the Seoul Viosys Z5 near-UV LED family. It uses a 3.5 x 3.5 x 2.0mm SMD package and low thermal resistant material, helping engineers create compact UV light engines without using large traditional lamp structures. The 500mA current level makes it a practical choice for designs that require strong 385nm output without moving to 1000mA high-current versions.
The 385nm wavelength is commonly used 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 creates more visible violet output, which can help visual alignment, inspection visibility, and UV-reactive display effects.
For production applications, these UVA LEDs 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 energy. Final performance depends on material chemistry, exposure distance, driver current, optical layout, heat dissipation, and required UV dose.
The 120° viewing angle provides broad area coverage. This makes the CUN86A1B different from narrow-beam 45° or 65° emitters that concentrate UV output into a smaller spot. The wide-beam structure is useful for curing panels, printing paths, fluorescence fields, UV-reactive inspection, and wide-angle UV flashlight designs.
For OEM and ODM projects, the CUN86A1B 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 all high power UVA LEDs. 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 lamp. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN86A1B 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.
