365nm uv diode Seoul Viosys UVA CUN66A1G
Product Details Description
Seoul Viosys CUN66A1G is a high power 365nm uv diode that is used in professional UV-A equipment requiring powerful output, compact size, and wide irradiation coverage. Being a 365nm wavelength, 2000mW radiant power, 3.7V voltage, 1000mA current, and 120° view angle, this diode is suitable for manufacturers who want to create UV curing, UV flashlights, printing, inspection lights, and other UV LED modules.
Seoul Viosys CUN66A1G is a part of the Z5 near-UV LED family. It was created for high current and high power usage. The 3.5 x 3.5 x 2.0mm SMD package allows engineers to create small UV light engine by avoiding traditional bulky lamp design.
365nm wavelength is chosen because it provides a strong fluorescence reaction and weak visible purple interference comparing with longer UVA wavelengths. This is why the CUN66A1G is suitable for counterfeit detection, security check, fluorescence photography, crime inspection, leak detection, UV torch designing, and other material inspections.
For curing and manufacturing purposes, this 365nm uv diode can be used in UV curing, printing, coating, adhesive curing, dental curing, and other UV-A operations if the material is responding to the 365nm. Final result will depend on the adhesive or coating chemistry, exposure distance, driver current, optics, heat dissipation, and required curing dose.
120° view angle provides a wide UV distribution in the working area. It differs from a narrow-beam 365nm LEDs, which concentrate the energy on a smaller area. This wide-angle design is suitable when engineers need to cover more area on the panel, on the 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 suitable for most of the UV modules’ designs, but copper PCB can be chosen when more thermal transfer is needed. The diode can be provided as the component or as the part of the UV flashlight modules, curing modules, inspection lamps, and other customized UV LED modules.
Thermal designing is one of the most significant parts of this high current 365nm uv diode. To provide stable radiant output and long term operation, it is necessary to use a suitable constant current driver, right soldering process, right PCB material, and enough heat dissipation. Engineers should check board temperature, radiant output, beam coverage, and application performance inside the final product before mass production.
It is a UV LED component, not a finished lamp. A complete product should include driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure.
Seoul Viosys CUN66A1G is a 365nm UVA light source, not UVC sterilization diode. It shouldn’t be promoted for disinfection or germicidal applications. Never look directly at the operating LED, and avoid unnecessary skin or eye exposure. Use protective eyewear, shielding, and safe work procedures during testing, assembling, and operation.
