uv diode led Seoul Viosys 395nm CUN96B1B
Product Details Description
The Seoul Viosys CUN96B1B is a high power uv diode led designed for professional UV-A applications that require compact size, strong radiant output, and a directed beam profile. With a 395nm wavelength, 3.5V voltage, 500mA current, 1250mW radiant power, and 45° view angle, it is suitable for manufacturers building UV curing tools, printing systems, coating equipment, UV flashlights, and inspection modules.
This uv diode led belongs to the Seoul Viosys nZ5 near-UV LED series. It is designed for high current operation and high power output, using a state-of-the-art SMD structure with low thermal resistance material. The compact 3.5 x 3.5 x 2.8mm package helps engineers create high-output UV modules without using larger lamp structures.
The 395nm wavelength is commonly selected for UV curing, printing, coating, adhesive applications, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection, and oil leak detection. Since 395nm is in the UVA / near-UV range, this uv diode led is not intended for UVC sterilization or germicidal claims.
The 45° viewing angle provides a narrower and more directional output than wide-angle UV emitters. This is useful for applications where UV energy should be concentrated onto a limited working area, such as spot curing, resin curing, adhesive bonding, coating inspection, document checking, forensic inspection, and leak detection. Final performance depends on current control, optical design, lens or reflector choice, working distance, target material, and thermal structure.
For OEM and ODM projects, the CUN96B1B can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is suitable for many cost-effective UV module designs, while copper PCB can be selected when higher thermal conductivity is required. The LED can be supplied as a component or assembled into UV flashlight modules, curing modules, inspection lights, and customized UV LED assemblies.
Thermal management is critical for high power UV LED products. To support stable output and service life, this uv diode led should be used with a suitable constant-current driver, correct soldering process, proper PCB material, and sufficient heat dissipation. Engineers should verify temperature, radiant output, and optical performance inside the final product before mass production.
This product is a UV LED component, not a complete finished lamp. A complete device should include a suitable driver, PCB, heat sink, housing, lens, wiring, switch, and safety structure. For industrial, dental, curing, and inspection use, protective eyewear and shielding are recommended.
Do not look directly at the operating LED or expose skin and eyes to unnecessary UV radiation. Follow safe handling procedures during testing, assembly, and use.
