405nm uv led seoul viosys ultraviolet uv led modules
Product Details Description
The Seoul Viosys CUN06B1B is a high power 405nm UV LED developed for manufacturers that need a compact SMD light source with directed output, strong radiant power, and flexible PCB integration. With 405nm wavelength, 1160mW radiant power, 3.5V voltage, 500mA current, and a 45° view angle, it is suitable for UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This 405nm UV LED belongs to the Seoul Viosys nZ5 near-UV LED family. It is designed for high current operation and high power output applications, using a state-of-the-art SMD design and low thermal resistant material. The 3.5 x 3.5 x 2.8mm package provides a compact platform for PCB-mounted UV light engines and portable industrial tools.
The 405nm wavelength is often 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 or 385nm sources, a 405nm UV LED normally produces more visible violet output, which can help operators see the working area, alignment position, and UV-reactive response more clearly.
For curing applications, the CUN06B1B can be integrated into adhesive curing tools, printing equipment, coating systems, resin curing devices, and dental curing modules when the target material responds to 405nm output. Final curing performance depends on the material chemistry, exposure distance, driver current, optical design, PCB temperature, and required energy dose.
The 45° narrow viewing angle makes this model suitable for focused UV delivery. It is different from 120° wide-beam LEDs that spread output across a larger surface. This focused beam can be useful for spot curing, adhesive bonding lines, handheld inspection lamps, compact exposure heads, UV torch modules, and detection equipment.
For OEM and ODM projects, the CUN06B1B 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 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 shape, and application performance inside the final product before mass production.
This product is a component-level 405nm UV LED, not a complete finished lamp. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN06B1B is a 405nm near-UV / violet-edge light source, not a UVC sterilization LED, and should not be promoted for disinfection or germicidal applications.
Do not look directly at the operating LED, and avoid unnecessary eye or skin exposure during testing, assembly, and operation. Use protective eyewear, shielding, warning labels, and safe working procedures in the final product design.
