uv led chip 395nm Seoul Viosys CUN96A1B
Product Details Description
Seoul Viosys CUN96A1B is a high power uv led chip 395nm designed for professional UV-A applications, such as small size, wide beam coverage, and reliable SMD. With 395nm wavelength, 1250mW radiant power, 3.5V voltage, 500mA current, and 120° view angle, it is suitable for manufactures who want to develop UV curing tools, printing system, coating equipment, inspection lamp, UV torch and customize UV LED modules.
This uv led chip 395nm is designed for high current operation and high power output applications. It features advanced SMD design and low thermal resistant material, making it easy to design board level UV light source. The 3.5 x 3.5 x 2.0mm package provides compact size for products requiring high 395nm output without bulky traditional lamp.
The 395nm wavelength is generally chosen for UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection, and oil leak detection. The 395nm is known to give more visible violet output compared with 365nm UV source, which is useful for UV reactive displays, visible alignment, and inspection where bright purple response is acceptable.
In terms of production applications, this uv led chip 395nm can be integrated into UV curing modules, printing equipment, coating system, adhesive curing tool, and dental curing device if the target material will react with 395nm UV-A energy. Performance depends on material chemistry, exposure distance, driver current, optical design, heat dissipation, and required UV dose.
With 120° view angle, this model is suitable for wide-area coverage. It is different from 45° or 65° narrow-beam UV LEDs, which focuses the output into smaller spot. The wide beam is beneficial for curing panels, fluorescence areas, printing path, 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. The aluminum PCB is appropriate for most standard UV module designs, while the copper PCB can be considered for better thermal transfer. The LED can be provided as components and assembled into UV flashlight modules, curing modules, inspection lamps, and other customized UV LED products.
The thermal design is crucial for 500mA high output UV LED. For reliable radiant output and long term performance, use suitable constant current driver, proper soldering technology, proper PCB material, and sufficient heat dissipation. Engineers should check the board temperature, radiant output, beam distribution, and application performance in final product prior to mass production.
This product is UV LED component, not UV lamp. The completed device should include driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch and safe structure. CUN96A1B is uv led chip 395nm UVA light source, not UVC sterilization LED, which should not be used and promoted for disinfection or germicidal application.
Do not look directly at the operating UV LED and avoid unnecessary exposure. Wear protective eyewear, shield, label, and follow safe procedures during testing, assembling, and operation.
