3W uv led chip Seoul Viosys UV 385nm CUN86B1G
Product Details Description
The Seoul Viosys CUN86B1G is a high power 3W uv led chip developed for professional UV-A applications that require strong radiant output, compact SMD integration, and a controlled beam profile. With a 385nm wavelength, 2050mW radiant power, 3.6V voltage, 1000mA current, and 65° view angle, it is suitable for manufacturers developing UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and customized UV LED modules.
This 3W uv led chip belongs to the Seoul Viosys nZ5 near-UV LED family. It is designed for high current operation, narrow viewing angle, and high power output applications. The 3.5 x 3.5 x 2.8mm SMD package allows engineers to build compact UV light engines without using bulky traditional lamp structures.
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 provides more visible violet output, which can help visual alignment and UV-reactive inspection while still offering useful UV-A energy.
For production applications, this 3W uv led chip 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 design, thermal structure, and required UV dose.
The 65° view angle gives this model a controlled beam profile. It is more focused than wide 120° UV LEDs but less concentrated than tight spot emitters. This makes the CUN86B1G suitable for UV flashlight heads, handheld inspection lamps, medium-area curing modules, coating inspection tools, and compact exposure devices.
For OEM and ODM projects, the CUN86B1G 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 high-output UV LED. To support stable radiant output and long-term performance, use a suitable constant-current driver, proper soldering process, appropriate PCB material, and enough heat dissipation. Engineers should verify board temperature, radiant output, beam pattern, 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 CUN86B1G 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.
