uv led emitters 405nm
Product Details Description
The Seoul Viosys CUN06A1G is a high power 405nm LED designed for manufacturers that need compact UV LED emitters with broad beam distribution, strong radiant output, and flexible PCB integration. With 2050mW radiant power, 3.5V voltage, 1000mA current, and a 120° view angle, it is suitable for UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This model belongs to the Seoul Viosys Z5 NUV LED family. It uses a state-of-the-art SMD design and a 3.5 x 3.5 x 2.0mm package, helping product engineers build high-output light engines without using bulky traditional lamp sources. The compact package is useful for portable tools, board-level modules, and space-limited equipment designs.
The 405nm wavelength is commonly 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 shorter near-UV wavelengths such as 365nm or 385nm, 405nm usually produces stronger visible violet output, which can help operators see alignment, coverage, and UV-reactive response more easily.
For curing applications, these UV LED emitters can be integrated into adhesive curing tools, resin curing devices, printing equipment, coating systems, and dental curing modules when the target material responds to 405nm output. Final curing performance depends on material chemistry, exposure distance, driver current, optical layout, PCB temperature, and required energy dose.
The 120° beam angle gives the CUN06A1G a wide output profile. This makes it different from 45° or 65° narrow-beam LEDs that focus output into a smaller spot. The wide-beam design is useful for broader curing surfaces, printing paths, fluorescence areas, inspection lamps, and wide-angle UV torch modules.
For OEM and ODM projects, the CUN06A1G can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB can be used for many standard 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 UV LED emitters operating at 1000mA. 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 component-level 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 CUN06A1G 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.
