uv diode led Seoul Viosys 395nm CUN96B1B
Product Details Description
The Seoul Viosys CUN96B1B is a high power uv diode led which is specially designed for professional UV-A applications that demand small size, high output, and directional beam profile. With a 395nm wavelength, 3.5V voltage, 500mA current, 1250mW radiant power, and 45° view angle, it is ideal for manufacturers to make UV curing devices, printers, coating machines, UV flashlights, and UV inspection lamps.
The CUN96B1B uv diode led belongs to Seoul Viosys nZ5 near-UV LED family. It is made for high current operation and high output with advanced SMD structure and low thermal resistance materials. The compact size (3.5 x 3.5 x 2.8mm) allows the engineer to develop high-output UV modules without large lamp structures.
395nm is one of the most common wavelengths for UV curing, printing, coating, adhesive applications, counterfeit detection, security inspection, UV torches, fluorescence photography, dental curing, crime inspection, and oil leak detection. As 395nm is within the UVA / near-UV wavelength, the uv diode led is not designed for UVC sterilization or germicidal application.
The 45° view angle offers a narrower and more directional output compared to the wide-angle UV emitters. It is helpful for applications where UV energy should focus on the limited work surface like spot curing, resin curing, adhesive bonding, coating inspection, document checking, forensic inspection, and leak detection. The final performance would depend on current control, optical design, lens or reflector selection, working distance, target material, and thermal structure.
For OEM or ODM projects, the CUN96B1B can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. The aluminum PCB can be adopted for most of the cost-effective UV module development. If more thermal conductivity is needed, copper PCB will be an alternative. The LED can be provided as a component or UV flashlight modules, curing modules, inspection lights, and customized UV LED modules.
Thermal management is important for high-power UV LEDs products. In order to ensure a stable output and long service life, this uv diode led should be worked together with a suitable constant-current driver, right soldering method, appropriate PCB material, and sufficient heat dissipation structure. The engineers should do the temperature, radiant output, and optical performance verification in the final product before mass production.
This product is a UV LED component and not a lamp. The completed device should include a suitable driver, PCB, heat sink, housing, lens, wire, switch, and safety structure. Protective eyewear and shielding are recommended for industrial, dental, curing, and inspection application.
Do not look directly at the operating LED and avoid exposing skin and eyes to unnecessary UV exposure. Follow the safe handling procedure during testing, assembly, and application.
