uv diode 365nm Seoul Viosys UVA CUN6UB1A
Product Details Description
The Seoul Viosys CUN6UB1A is a high power uv diode 365nm developed for manufacturers that need a compact UV-A light source with directed output, strong radiant power, and reliable SMD integration. With 365nm wavelength, 1000mW radiant power, 3.7V voltage, 700mA current, and a 60° view angle, it is suitable for UV curing, printing, coating, adhesive, UV torch, fluorescence photography, dental curing, crime inspection, and oil leak detection applications.
This uv diode 365nm belongs to the CU3737 near-UV LED family. It is designed for high current operation, narrow radiation angle, and high power output applications. The 3.7 x 3.7 x 2.8mm SMD package helps product engineers build compact UV modules without using large lamp structures.
The 365nm wavelength is often selected for applications that need strong fluorescence response and less visible purple interference than longer-wavelength UVA sources. This makes the CUN6UB1A useful for counterfeit detection, security inspection, fluorescence photography, crime inspection, oil leak detection, UV torch products, and specialized inspection modules.
For curing and production systems, this uv diode 365nm can be used in UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the material responds to 365nm UV-A energy. Final curing performance depends on material chemistry, exposure distance, driver current, optical design, working temperature, and required UV dose.
The 60° view angle provides a balanced beam profile. It is narrower than 120° wide-angle UV LEDs, but broader than very tight 35° spot emitters. This makes the product useful for engineers who need controlled UV coverage on a defined working area without making the beam too concentrated.
For OEM and ODM projects, the CUN6UB1A can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is suitable for many standard module designs, while copper PCB can be selected when stronger heat transfer is required. The diode can be supplied as a component or assembled into UV flashlight heads, curing modules, inspection lamps, and customized UV LED products.
Thermal management is important for this 700mA UV LED. To support stable radiant output, use a suitable constant-current driver, proper soldering process, appropriate PCB material, and enough heat dissipation. Engineers should test board temperature, radiant output, beam pattern, and application performance inside the final device before mass production.
This product is a UV LED component, not a complete lamp. A finished product should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN6UB1A is a uv diode 365nm UVA source, not a UVC sterilization diode, and should not be promoted for disinfection or germicidal use.
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.
