uva leds Seoul Viosys UV 385nm CUN86A1B
Product Details Description
The Seoul Viosys CUN86A1B is a 385nm UV-A LED for manufacturers who need compact UVA LEDs with wide beam, high radiant output, and SMD compatibility. With 1200mW radiant power, 3.5V voltage, 500mA current, and 120° view angle, this UVA LED is good for uv curing tools, printing systems, coating equipment, inspection lamps, UV torch devices, and customized UV LED modules.
This product belongs to the Seoul Viosys Z5 near-UV LED series. It uses a 3.5 x 3.5 x 2.0mm SMD package and low thermal resistant material to allow engineers to build compact UV light engines without using bulky traditional lamp structures. The 500mA current is good for high power output 385nm designs without switching to 1000mA versions.
The 385nm wavelength is typically used 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 LEDs, 385nm usually generates more violet output, which could be good for visual alignment, inspection visibility, and UV-reaction effects.
For industrial applications, these UVA LEDs could be used to build UV curing modules, printing systems, coating equipment, adhesive curing tools, and dental curing devices when the target material reacts with 385nm UV-A energy. The final results would depend on material chemistry, exposure distance, current value, optical design, heat dissipation, and UV dose requirement.
The 120° viewing angle provides wide area illumination. Thus, the CUN86A1B is different from the narrow-beam 45° or 65° emitters that focus UV output into a spot. The wide-beam design is good for curing panels, printing paths, fluorescence fields, UV reaction inspection, and UV flashlight products.
For OEM and ODM projects, the CUN86A1B could be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. The aluminum PCB is good for most of standard UV module designs while copper PCB could be used for better thermal transfer. This UV LED could be offered as a component or UV flashlight modules, curing modules, inspection lamps, and other customized UV LED products.
Thermal management is always important for all high power UVA LEDs. For stable radiant output and long-time performance, a proper constant current driver, good soldering process, right PCB material, and sufficient heat dissipation should be used. Engineers have to check board temperature, radiant output, beam distribution, and application performance in the final product before mass production.
This product is a UV LED component and not a lamp. A finished product should have a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety protection structure. The CUN86A1B is a 385nm UVA light source, not a UVC sterilization LED, and should not be promoted for disinfection or germicidal applications.
Avoid looking directly at the operating UV LED and unnecessary skin or eye exposure. Use protective eyewear, shielding, warning labels, and safe working procedure when testing, assembling, and operating UV LED.
