Product Details Description
The Seoul Viosys OEM-365nm is a custom 365nm LED module solution for manufacturers that need a flexible UV-A light source rather than a fixed standard component. It is designed for UV curing, printing, coating, adhesive, counterfeit detection, security inspection, UV torch, fluorescence photography, dental curing, crime inspection, and oil leak detection applications.
This 365nm LED module can be customized by size, voltage, radiant power, LED quantity, PCB layout, connector, wire, lens, heat sink, and housing. The current range is 250–1000mA for each LED, allowing engineers to select different power levels according to the application. The module can be developed for compact handheld devices, industrial equipment, inspection lamps, UV flashlight engines, or machine-mounted UV exposure systems.
The 365nm wavelength is widely used for UV-A curing and fluorescence-based detection. Compared with longer wavelengths such as 395nm, a 365nm LED usually produces less visible purple light and can create stronger fluorescence contrast in many inspection applications. This makes it useful for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, and UV torch products.
For curing applications, this 365nm LED module can be used in adhesive curing tools, coating curing systems, printing equipment, resin exposure devices, and dental curing modules when the target material responds to 365nm UV-A energy. Final curing performance depends on material chemistry, LED quantity, radiant power, exposure distance, driver current, optical design, heat dissipation, and required UV dose.
The 120° view angle supports broad UV-A distribution. This is useful for wide inspection fields, printing paths, curing panels, and UV-reactive surfaces. For applications that require a more concentrated beam, the final module can be designed with lenses, reflectors, or housing structures to adjust the beam pattern.
This custom 365nm LED product uses SMT-type LED technology and is suitable for high current operation. The design supports high power output, low thermal resistance, lead free structure, and RoHS compliant module development. Proper thermal design is important because higher current and higher radiant power require suitable PCB material, heat sinking, driver control, and long-term temperature testing.
As an OEM and ODM UV LED module, the product can be configured for different assembly formats. Options may include aluminum PCB, copper PCB, round board, strip board, multi-LED array, UV flashlight module, curing head, inspection lamp module, or other custom UV light source designs. Voltage and radiant power should be confirmed according to the final LED arrangement and driver system.
This product is a UV LED module or module component, not a complete finished lamp unless specified in the final OEM design. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The OEM-365nm module is a 365nm UV-A light source, not a UVC sterilization module, and should not be promoted for disinfection or germicidal applications.
Do not look directly at the operating 365nm LED module. 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.
