uv led diode 365nm Seoul Viosys CUN66B1G
Product Details Description
The Seoul Viosys CUN66B1G is a high power uv led diode designed for professional 365nm UV-A applications that require small size, powerful radiant power, and narrow output beam angle. It has 365nm wavelength, 2000mW radiant power, 3.7V voltage, 1000mA current, and 65° view angle. It is an excellent component for companies that manufacture UV curing devices, UV flashlights, inspection systems, printing equipment, and custom UV LED modules.
This uv led diode is part of the Seoul Viosys nZ5 near-UV LED family. This uv led diode is designed for high current operation, narrow-angle output, and high power performance. The 3.5 x 3.5 x 2.8mm SMD structure makes it easier for engineers to create small UV light engines without bulky lamp structure.
The 365nm wavelength is frequently used in cases that need high fluorescence response and little visible interference. This uv led diode can be used for UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch design, fluorescence photography, dental curing, crime inspection, and oil leak detection. As it is a UVA / near-UV source, it must not be promoted as a UVC disinfection or germicidal LED.
The 65° view angle provides a more focused UV beam than the dome type LEDs with wide view angle. It is beneficial when UV energy needs to be focused on a certain target area, such as a curing spot, inspection area, adhesive line, coating surface, fluorescent material, or leak detection spot. Final performance depends on driver current, lens design, reflector design, working distance, heat dissipation, and target material response.
For OEM and ODM projects, the CUN66B1G can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB is an ideal choice for many cost-efficient UV module designs, while copper PCB can be selected in cases that require better heat transfer ability. The LED can be provided as a component or assembled into UV flashlight modules, curing modules, inspection lamps, and custom UV LED products.
Heat dissipation design is crucial for this high-current UV LED diode. For ensuring the stable operation of this LED, it is necessary to use a proper constant-current driver, proper soldering process, proper PCB material, and adequate heat dissipation. Engineers are suggested to check board temperature, radiant power, optical performance, and service stability in the final product before going to mass production.
This product is a UV LED component rather than a completed finished lamp. A completed device must consist of a driver circuit, PCB board, heat sink, housing, lens or reflector, wires, switch, and safety design. For curing, dental, inspection, security, and industrial applications, shielding and protection eyewear are recommended.
Do not stare at the operating LED or expose your skin and eyes to unnecessary UV radiation. Follow safe handling procedure during testing, mounting, and operation.
