led uv diode Seoul Viosys UVA 365nm CUN6UC1A
Product Details Description
The Seoul Viosys CUN6UC1A is a 365nm led uv diode used in applications requiring high-current capability, compact SMD mounting, and focused UVA emission. Having 900mW radiant power, 3.7V voltage, 700mA current, and 35° view angle, it is suitable for the manufacturing of UV curing tools, UV printing equipment, inspection lamps, UV torches, and custom UV LED modules.
This led uv diode is from the CU3737 near-UV LED series. It is intended for applications with high current operation, narrow radiation angle, and high power output requirements. The SMD package is compatible with the modern assembly process, whereas the low thermal resistant material increases the heat dissipation when the LED is used with a proper PCB and cooling structure.
The 365nm wavelength is widely used for UV-A curing, fluorescence excitation, security checking, and material reaction applications. In comparison with longer 395nm UV sources, 365nm usually generates a better fluorescence response and has less visible purple light; therefore, the CUN6UC1A can be applied for counterfeit detection, crime inspection, oil leak detection, fluorescence photography, and UV torch products.
For curing and production applications, this led uv diode can be used in UV curing modules, printing systems, coating equipment, adhesive curing tools, and dental curing devices when the material reacts to 365nm. The 35° narrow beam will help focus UV output on the small working area.
For detection applications, the CUN6UC1A can be used for counterfeit detection, security inspection, fluorescence photography, crime inspection, and oil leak detection. The final performance will depend on the optical design, working distance, driver current, reflector or lens choice, target material, and thermal structure.
For OEM and ODM projects, this led uv diode can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. The aluminum PCB board can be used for all standard UV module designs, whereas the copper PCB can be chosen when higher thermal dissipation is needed. The diode can be offered as a separate component or assembled in UV flashlight heads, curing modules, inspection lamps, and other customized UV LED products.
Thermal design is important for the stable radiant output. You should use a proper constant current driver, correct soldering process, correct PCB material, and sufficient heat dissipation. Engineers should test the board temperature, UV output, beam pattern, and application performance in the final device before the mass production.
This product is a UV LED component and not a lamp. A finished product should include the driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN6UC1A is a 365nm UVA source and not a UVC sterilization diode and should not be advertised 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.
