365nm uv diode Seoul Viosys UVA CUN66A1G
Product Details Description
The Seoul Viosys CUN66A1G is a high power 365nm uv diode developed for professional UV-A equipment that requires strong output, compact size, and broad irradiation coverage. With 365nm wavelength, 2000mW radiant power, 3.7V voltage, 1000mA current, and 120° view angle, it is suitable for manufacturers building UV curing tools, UV flashlights, printing systems, inspection lights, and custom UV LED modules.
This 365nm uv diode belongs to the Seoul Viosys Z5 near-UV LED series. It is designed for high current operation and high power output applications. The 3.5 x 3.5 x 2.0mm SMD package allows engineers to design compact UV light engines without using bulky traditional lamp structures.
The 365nm wavelength is widely selected for applications that need strong fluorescence response and reduced visible purple interference compared with longer UVA wavelengths. This makes the CUN66A1G useful for counterfeit detection, security checking, fluorescence photography, crime inspection, leak detection, UV torch design, and material inspection.
For curing and production applications, this 365nm uv diode can be used in UV curing, printing, coating, adhesive curing, dental curing, and related UV-A processes when the material is responsive to 365nm. Final performance depends on the adhesive or coating chemistry, exposure distance, driver current, optical structure, heat dissipation, and required curing dose.
The 120° view angle provides wide UV distribution across the working area. This is different from narrow-beam 365nm LEDs that concentrate energy into a smaller spot. The wide-angle structure is useful when engineers need more coverage for a panel, inspection surface, curing area, or fluorescence field.
For OEM and ODM projects, the LED can be assembled on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is practical for many standard UV module designs, while copper PCB can be selected when stronger thermal transfer is needed. The diode can be supplied as a component or integrated into UV flashlight modules, curing modules, inspection lamps, and other customized UV LED assemblies.
Thermal design is important for this high-current 365nm uv diode. To support stable radiant output and long-term operation, use a suitable constant-current driver, proper soldering process, suitable PCB material, and enough heat dissipation. Engineers should verify board temperature, radiant output, beam coverage, and application performance inside the final product before mass production.
This product is a UV LED component, not a complete finished lamp. A complete product should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure.
The CUN66A1G is a 365nm UVA light source, not a UVC sterilization diode. It should not be promoted for disinfection or germicidal applications. Do not look directly at the operating LED, and avoid unnecessary skin or eye exposure. Use protective eyewear, shielding, and safe working procedures during testing, assembly, and operation.
