uv led emitters 405nm
Product Details Description
Seoul Viosys CUN06A1G is a high-power 405nm LED which can be used by manufacturers in their products as compact UV LED emitters with wide beam, high radiant output and flexible PCB mounting option. With 2050mW radiant power, 3.5V voltage, 1000mA current and 120° view angle, this LED can be applied in UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products and customized UV LED modules.
This model is part of the Seoul Viosys Z5 NUV LED series. The advanced SMD construction and 3.5 x 3.5 x 2.0mm package help product engineers to create high-output light engines without using heavy traditional lamp sources. Small LED package is suitable for portable devices, board-level modules and limited-space device designs.
405nm wavelength is commonly used in UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection and oil leak detection applications. Comparing to shorter near-UV wavelengths like 365nm or 385nm, 405nm LEDs usually provide higher visible violet output that can help operators better to see alignment, coverage and reaction to UV light.
For curing applications, these UV LED emitters can be used in adhesive curing tools, resin curing devices, printing equipment, coating systems and dental curing modules if target material reacts to 405nm output. The final curing results depend on material chemistry, exposure distance, driving current, optical design, PCB temperature and required energy dose.
The 120° view angle makes the Seoul Viosys CUN06A1G LED different from 45° or 65° narrow-beam LEDs with focused output spot. Wide-beam design is suitable for wider curing areas, printing paths, fluorescence areas, inspection lamps and wide-angle UV torch modules.
The Seoul Viosys CUN06A1G LED can be welded on 12mm, 14mm, 16mm, 20mm or any other aluminum or copper PCB board in OEM and ODM projects. Aluminum PCB can be used for most of standard module designs and copper PCB can be selected if stronger thermal transfer is required. The LED can be supplied as a single component or assembled into UV flashlight modules, curing modules, inspection lamps and other customized UV LED products.
Proper thermal design is important for UV LED emitters working at 1000mA current. To provide stable radiant output and long-time performance, you should use appropriate constant-current driver, proper soldering procedure, proper PCB material and proper heat dissipation. Product engineers should test board temperature, radiant output, beam distribution and application performance inside the final product before mass production start.
This product is a component-level LED and it is not a finished lamp. The finished device should include the driver circuit, PCB board, heat sink, housing, optical lens or reflector, wires, switch and safety design. The Seoul Viosys CUN06A1G is a 405nm near-UV / violet-edge light source and it is not UVC sterilization LED and should not be promoted for disinfection or germicidal applications.
Do not look directly to the operating LED and avoid unnecessary eye or skin exposure during testing, assembly and work with this product. Use protective eyewear, shielding, warning label and safe working procedure in the final product design.
