uv light diode Seoul Viosys UVA 365nm CUN66A1B
Product Details Description
Seoul Viosys CUN66A1B is a 365nm uv light diode that is intended for manufacturers who need a small and wide-beam UVA light source for curing, printing, detecting, UV flashlight, and designing customized UV LED modules. With 1000mW radiant power, 3.6V voltage, 500mA current, and 120° view angle, this product offers an efficient combination of radiation power, current level, and wide-area covering.
This UV light diode is part of a high power UV LED series designed for high current and high output applications. The advanced SMD design and low thermal resistant material are used to facilitate board-level design of compact UV devices. Thanks to the 3.5 x 3.5 x 2.0mm package, it becomes possible for engineers to design smaller UV modules while providing useful 365nm radiant output.
365nm wavelength is often used in applications that require fluorescence reaction, UV-A curing, inspection, detection, and material activation. In comparison with 395nm UV, 365nm can provide stronger fluorescence reaction and less visible purple interference in many inspection cases. Therefore, the CUN66A1B can be used for counterfeit detection, security check, fluorescence photography, crime inspection, oil leak detection, UV torch products, and insect trap light sources.
In case of curing and production use, this uv light diode can be incorporated into UV curing modules, printing units, coating machines, adhesive curing tools, and dental curing units provided that the target material responds to 365nm. The final performance will depend on material chemistry, distance to exposure, driver current, optical design, thermal design, and required curing dosage.
The 120° view angle makes the output covering wider. It is needed when an area exposure is necessary instead of concentrated spot beam. This feature can be useful for broad inspection fields, fluorescence panels, insect trap illumination areas, small curing area, and wide beam UV flashlight modules.
For OEM and ODM projects, the CUN66A1B can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is suitable for most standard UV module designs while copper PCB can be chosen for projects where better thermal transfer is needed. The diode can be provided as a component or mounted into UV flashlight modules, curing modules, detecting lamps, insect trap modules, and other customized UV LED products.
Proper thermal design is very important for stable operation. A suitable constant-current driver, right soldering process, correct PCB material, and good heat dissipation should be used. Engineers are supposed to test temperature of the board, radiant output, beam coverage, and application performance within the final product before mass production.
This uv light diode is a UV LED component and not a lamp. A complete device is supposed to include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN66A1B is a 365nm UVA light source and not a UVC sterilization diode and is not supposed to be promoted for disinfection or germicidal use.
Avoid looking directly at the operating UV LED and unnecessary skin or eye exposure. Protective eyewear, shielding, warning labels, and safe working procedures are recommended for testing, assembly, and operation.
