3W uv led chip Seoul Viosys UV 385nm CUN86B1G
Product Details Description
CUN86B1G, 385nm 3W uv led chip is a high power professional UV-A LED chip with 3W radiant power. With its wavelength at 385nm, 2050mW radiant power, 3.6V forward voltage, 1000mA operating current and 65° view angle, it is ideal for developing UV-A curing, printing, coating, inspection, UV torch products and customized UV LED modules.
This 3W uv led chip is a member of the Seoul Viosys nZ5 series of near-UV LEDs. It is a high current, narrow viewing angle and high power output LED chip. It features a 3.5 x 3.5 x 2.8mm SMD package, allowing the designer to assemble a compact UV light engine without using conventional lamps.
385nm wavelength is widely chosen for UV curing, printing, coating, adhesive curing, counterfeit detection, security inspection, UV torch products, fluorescence photography, dental curing, crime inspection and oil leak detection. When comparing with 365nm UV LEDs, the 385nm wavelength will produce more visible violet output, which is helpful for visual alignment and UV reactive inspection but still offers effective UV-A radiation.
For industrial applications, this 3W uv led chip can be assembled into UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the material responds to 385nm UV-A energy. Performance will depend on material chemistry, distance, driver current, optical design, thermal structure and UV dose needed.
The 65° view angle of this model offers a controlled beam profile. It is more focused than wide 120° UV LEDs but less concentrated than tight spot emitters. It is applicable for UV flashlight heads, handheld inspection lamps, medium area curing modules, coating inspection tools and compact exposure devices.
For OEM and ODM projects, the CUN86B1G can be assembled on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB board can be used for most standard UV module designs. Copper PCB can be chosen for better thermal transfer if needed. This 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 necessary for a 1000mA high power output UV LED. For achieving stable radiant output and long term operation, use a suitable constant current driver, good soldering procedure, right PCB material and sufficient heat dissipation. Engineers need to validate the board temperature, radiant output, beam pattern and application performance in the final product.
This product is a UV LED component, not a complete lamp. A finished lamp needs a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch and safety structure. The CUN86B1G is a 385nm UVA light source, not a UVC sterilization LED and should not be promoted for disinfection and germicidal applications.
Do not look directly at the working UV LED, and avoid unnecessary skin and eye exposure. Wear protective eyewear and use shielding, warning label and safe operation method when testing, assembling and operating.
