Original Seoul Viosys UVA led uv lights solution
Product Details Description
The Seoul Viosys CUN6HB4A is an ultra high power Seoul Viosys UVA LED developed for professional 365nm UV-A systems. With 5300mW radiant power, 7.8V voltage, 2000mA current, and a 70° view angle, it is suitable for manufacturers that need a strong UV source for curing, printing, coating, adhesive, UV torch, fluorescence photography, dental curing, crime inspection, and oil leak detection applications.
This Seoul Viosys UVA LED uses a 6.8 x 6.8 x 3.7mm SMD package. The larger package size helps support high-power UV output and practical module integration. It incorporates a modern SMD design and low thermal resistant material, making it suitable for high current operation when used with proper PCB design, current control, and heat dissipation.
The 365nm wavelength is widely selected for UV-A curing and fluorescence-based detection. Compared with longer UVA wavelengths such as 395nm, 365nm often provides stronger fluorescence response and less visible purple interference in many inspection applications. This makes the CUN6HB4A useful for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, and UV torch products.
For production and curing applications, this Seoul Viosys UVA 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 365nm. The 5300mW radiant power gives product designers a high-output option for applications where lower-power 365nm emitters may not provide enough UV intensity.
The 70° view angle creates a controlled UV beam that is wider than tight spot LEDs but more directed than 120° wide-beam emitters. This beam profile is useful for UV curing heads, handheld inspection lights, UV flashlights, compact exposure modules, and equipment designs that require strong output across a defined working area.
For OEM and ODM projects, the CUN6HB4A 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 thermal 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 critical for this 2000mA high-power UV LED. To support stable radiant output and long service performance, use a suitable constant-current driver, proper soldering process, suitable PCB material, enough heat dissipation, and protection against electrical overstress. Engineers should verify board temperature, radiant output, beam profile, and application performance inside the final product before mass production.
This Seoul Viosys UVA LED is a component, not a complete finished lamp. A complete UV device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN6HB4A is a 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.
