uv led chip 395nm Seoul Viosys CUN96A1B
Product Details Description
The Seoul Viosys CUN96A1B is a high power uv led chip 395nm developed for professional UV-A applications that require compact size, wide beam coverage, and reliable SMD integration. With 395nm wavelength, 1250mW radiant power, 3.5V voltage, 500mA current, and a 120° view angle, it is suitable for manufacturers developing UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This uv led chip 395nm is built for high current operation and high power output applications. It incorporates a state-of-the-art SMD design and low thermal resistant material, making it suitable for board-level UV light-source designs. The 3.5 x 3.5 x 2.0mm package provides a compact form factor for products that need strong 395nm output without using a large traditional lamp.
The 395nm wavelength is commonly selected for UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection, and oil leak detection. Compared with 365nm UV sources, 395nm typically produces more visible violet output, which can be useful for UV-reactive display effects, visible alignment, and inspection tasks where a brighter purple response is acceptable.
For production applications, this uv led chip 395nm can be integrated into UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the target material responds to 395nm UV-A energy. Final performance depends on material chemistry, exposure distance, driver current, optical design, heat dissipation, and required UV dose.
The 120° view angle makes this model suitable for broad-area coverage. It is different from 45° or 65° narrow-beam UV LEDs that concentrate output into a smaller spot. The wide beam is useful for curing panels, fluorescence areas, printing paths, UV-reactive inspection, and wide-angle UV flashlight modules.
For OEM and ODM projects, the CUN96A1B 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 when stronger thermal transfer is required. The LED can be supplied as a component or assembled into UV flashlight modules, curing modules, inspection lamps, and other customized UV LED products.
Thermal design is important for a 500mA high-output UV LED. To support stable radiant output and long-term performance, use a suitable constant-current driver, proper soldering process, appropriate PCB material, and enough heat dissipation. Engineers should verify board temperature, radiant output, beam distribution, and application performance inside the final product before mass production.
This product is a UV LED component, not a complete lamp. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN96A1B is a uv led chip 395nm UVA light source, not a UVC sterilization LED, and should not be promoted 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.
