uv emitter Seoul Viosys uv modules customizable
Product Details Description
The Seoul Viosys CUN06A1B is a high power 405nm uv emitter which is intended for manufacturers requiring wide beam angle, high radiant power and small SMD integration. Due to its 405nm wavelength, 1160mW radiant power, 3.5V voltage, 500mA current and 120° view angle, it is applicable for UV curing devices, printing systems, coating devices, inspection lamps, UV torch products, custom UV LED modules.
This uv emitter belongs to the Seoul Viosys Z5 NUV LED series. It has a modern SMD packaging technology and low thermal resistant material, assisting engineers in building board-level near-UV light sources without usage of large traditional lamps. The size of 3.5 x 3.5 x 2.0mm is convenient for small modules, portable devices and limited equipment designs.
The 405nm wavelength is popular in UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection, oil leak detection. In comparison with shorter near-UV wavelengths, for example, 365nm or 385nm, 405nm usually provides stronger visible violet output, making it easier to detect alignment, coverage and UV-reactive response.
For curing purposes, this uv emitter can be implemented in adhesive curing devices, resin curing devices, printing equipment, coating systems and dental curing modules in case the target material reacts on 405nm radiation. The curing efficiency will depend on material chemistry, exposure distance, driving current, optics, PCB temperature and required energy dose.
The wide view angle of 120° makes the CUN06A1B have a wide output profile. This feature makes this device differ from 45° narrow-beam uv emitters focusing their output on a small target area. The wide-beam design is useful in large local exposure, curing panels, printing path, fluorescence field, inspection lamps and wide-angle UV torch designs.
For OEM and ODM applications, this CUN06A1B can be welded on 12mm, 14mm, 16mm, 20mm or other aluminum or copper PCB boards. Aluminum PCB is suitable for numerous standard UV module designs, while copper PCB can be used in case of higher thermal dissipation requirement. The LED can be supplied as a component or assembled in UV flashlight modules, curing modules, inspection lamps and other customized UV LED products.
Thermal design is an important part for high-output 500mA emitter. To ensure the stable radiant output and efficient operation, it is necessary to use an appropriate constant-current driver, right soldering process, adequate PCB material and sufficient heat dissipation. The engineers should verify the PCB temperature, radiant output, beam distribution and performance of the application inside the final product before mass production.
This product is a component-level uv emitter, but not a finished lamp. The completed product should have a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wires, switch and safe design. The CUN06A1B is a 405nm near-UV / violet-edge light source, but not UVC sterilization LED and should not be advertised for disinfection or germicidal applications.
Do not stare directly at the working LED, as well as do not expose your eyes or skin unnecessarily during testing, assembly and operation. Use special protection equipment, shielding, warning labels and safe procedures in the final product design.
