uv led chip 365nm Seoul Viosys UVA CUN6GB1A ultraviolet module customizable
Product Details Description
The Seoul Viosys CUN6GB1A is a high power uv led chip 365nm developed for professional UV-A applications that require compact size, strong radiant output, and controlled beam coverage. With 365nm wavelength, 1400mW radiant power, 3.7V voltage, 1000mA current, and a 65° view angle, it is suitable for manufacturers developing UV curing tools, printing systems, coating equipment, inspection lamps, UV torch products, and custom UV LED modules.
This uv led chip 365nm belongs to the CA3535 near-UV LED family. It incorporates a state-of-the-art SMD design and low thermal resistant material, making it suitable for high-current PCB-mounted UV light engines. The 3.5 x 3.5 x 2.5mm package provides a compact form factor for products that require strong 365nm output without using a large lamp structure.
The 365nm wavelength is widely used for UV-A curing and fluorescence-based detection. Compared with longer UVA wavelengths such as 395nm, 365nm often delivers stronger fluorescence response with less visible purple interference in many inspection tasks. This makes the CUN6GB1A useful for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, and UV torch applications.
For production applications, this uv led chip 365nm can be integrated into UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the target material responds to 365nm UV-A energy. Final performance depends on material chemistry, exposure distance, optical design, driver current, thermal structure, and required UV dose.
The 65° view angle gives this model a balanced optical profile. It is more concentrated than wide-beam 115° or 120° LEDs, but not as tight as 35° spot-type UV LEDs. This makes the CUN6GB1A suitable for UV flashlight heads, handheld inspection lamps, medium-area curing modules, coating inspection tools, and compact UV exposure devices.
For OEM and ODM projects, the CUN6GB1A 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 1000mA UV 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 pattern, and application performance inside the final product before mass production.
This product is a UV LED component, not a complete lamp. A finished device should include a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure. The CUN6GB1A is a 365nm UVA light source, not a UVC sterilization LED, and should not be promoted for disinfection or germicidal applications.
Do not look directly at the operating UV LED, and avoid unnecessary skin or eye exposure. Use protective eyewear, shielding, warning labels, and safe working procedures during testing, assembly, and operation.
