Seoul Viosys UV Diode 365nm CUN6UB1A

The Seoul Viosys CUN6UB1A is a high power uv diode 365nm meant for manufacturers who require a small-size UV-A light source with directed output, high radiant power, and good SMD integration features. With 365nm wavelength, 1000mW radiant power, 3.7V voltage, 700mA current, and 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. With 3.7 x 3.7 x 2.8mm SMD package, the product helps product engineers design compact UV modules without using bulky lamp structures.

The 365nm wavelength is selected in applications that require high fluorescence reaction and less visible purple interference as compared to long wavelength UVA sources. This makes the CUN6UB1A suitable for counterfeit detection, security inspection, fluorescence photography, crime inspection, oil leak detection, UV torch products, and special 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 requires 365nm UV-A energy. The final curing effect is dependent on material chemistry, exposure distance, driver current, optical design, working temperature, and required UV dosage.

The 60° view angle offers 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 require controlled UV irradiation on a certain working area without focusing the beam.

For OEM and ODM projects, the CUN6UB1A can be attached on 12mm, 14mm, 16mm, 20mm, or any other aluminum or copper PCB boards. Aluminum PCB can be used in most standard module designs, but the copper PCB can be used in cases where better heat transfer is needed. This uv diode 365nm can be delivered as a component or assembled into UV flashlight heads, curing modules, inspection lamps, and customized UV LED products.

Thermal management is key for this 700mA UV LED. For stable radiant output, use an appropriate constant-current driver, proper soldering process, correct PCB material, and sufficient heat dissipation. Product engineers should test PCB temperature, radiant output, beam profile, and application performance inside the final device prior to mass production.

This product is a UV LED component and not a finished lamp. A complete product should consist of 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 and not a UVC sterilization diode and thus should not be promoted for disinfection or germicidal use.

Avoid looking directly at the operating UV LED, and avoid unnecessary skin and eye exposure. Use protective eyewear, shielding, warning labels, and safe work practices during testing, assembling and operating.
