uv light diode Seoul Viosys UVA 365nm CUN66A1B
Product Details Description
The Seoul Viosys CUN66A1B is a 365nm uv light diode developed for manufacturers that need a compact, wide-beam UVA light source for curing, printing, detecting, UV flashlight, and custom UV LED module designs. With 1000mW radiant power, 3.6V voltage, 500mA current, and a 120° view angle, it provides a practical balance of output, current level, and wide-area coverage.
This uv light diode belongs to a high power UV LED series designed for high current operation and high output applications. It incorporates a state-of-the-art SMD design and low thermal resistant material, making it suitable for board-level integration in compact UV devices. The 3.5 x 3.5 x 2.0mm package helps engineers create smaller UV modules while maintaining useful 365nm radiant output.
The 365nm wavelength is commonly selected for applications that require fluorescence response, UV-A curing, inspection, detection, and material activation. Compared with 395nm UV sources, 365nm can provide stronger fluorescence reaction with less visible purple interference in many inspection tasks. This makes the CUN66A1B suitable for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, UV torch products, and insect trap light-source designs.
For curing and production use, this uv light diode can be integrated into UV curing modules, printing systems, coating equipment, adhesive curing tools, and dental curing devices when the target material responds to 365nm. Final performance depends on material chemistry, exposure distance, driver current, optical layout, thermal structure, and required curing dose.
The 120° viewing angle spreads UV output over a wider area. This is useful for designs that require area exposure instead of a concentrated spot beam. It can support broad inspection fields, fluorescence panels, insect trap illumination zones, compact curing surfaces, and wide-beam UV flashlight modules.
For OEM and ODM projects, the CUN66A1B can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is suitable for many standard UV module designs, while copper PCB can be selected for projects requiring stronger thermal transfer. The diode can be supplied as a component or assembled into UV flashlight modules, curing modules, detection lamps, insect trap modules, and other customized UV LED products.
Thermal design is important for stable operation. Use a suitable constant-current driver, proper soldering process, suitable PCB material, and sufficient heat dissipation. Engineers should test board temperature, radiant output, beam coverage, and application performance inside the final product before mass production.
This uv light diode is a UV LED component, not a finished lamp. A complete device should 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, not a UVC sterilization diode, and should not be promoted for disinfection or germicidal use.
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.
