Original Seoul Viosys UVA led uv lights solution
Product Details Description
Seoul Viosys CUN6HB4A is a ultra high power Seoul Viosys UVA LED for professional 365nm UV-A system with 5300mW radiant power, 7.8V voltage, 2000mA current, and 70° view angle. The CUN6HB4A UVA LED is appropriate for manufacture that needs high power UV source for curing, printing, coating, adhesive, UV torch, fluorescence photography, dental curing, crime inspection, and oil leak detection.
Seoul Viosys uses an advanced SMD design and low thermal resistant material in the 365nm CUN6HB4A UVA LED, which comes in a 6.8 x 6.8 x 3.7mm package. The larger package size helps to develop high-power UV and practical module design.
The wavelength of 365nm is chosen widely for UV-A curing and fluorescence-based detection. When compared to longer UVA wavelength like 395nm, 365nm LED has better fluorescence response and little interference of visible purple light in many inspection applications. The CUN6HB4A UVA LED is useful for counterfeit detection, security checking, fluorescence photography, crime inspection, oil leak detection, and UV torch products.
For production and curing application, this Seoul Viosys UVA LED is applicable for UV curing modules, printing equipment, coating systems, adhesive curing tools, and dental curing devices when the target material reacts to 365nm. The 5300mW radiant power gives the product designer a high-power choice for applications where 365nm low-power emitter cannot provide enough UV intensity.
The 70° view angle has a controlled UV beam that is wider than tight spot LEDs but more focused than 120° wide-beam emitter. The 70° view angle beam is helpful for UV curing heads, handheld inspection lights, UV flashlights, compact exposure modules, and equipment designs which need strong output in a limited working area.
The CUN6HB4A can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards in OEM and ODM projects. For many standard UV module designs, aluminum PCB is a good choice. The copper PCB is recommended when higher thermal transfer is needed. The LED can be provided as a component or assembled into UV flashlight heads, curing modules, inspection lamps, and customized UV LED products.
It is very important for the thermal design of this 2000mA high-power UV LED. In order to ensure the stability of the radiant output and the performance in the long term service, a proper constant-current driver, suitable soldering process, proper PCB material, sufficient heat dissipation, and protection against electrical overstress are necessary. The engineers are expected to test the board temperature, radiant output, beam profile, and performance in the final application before production in large quantity.
This Seoul Viosys UVA LED is only a component but not a complete finished lamp. For a complete UV device, the components including a driver circuit, PCB board, heat sink, housing, optical lens or reflector, wiring, switch, and safety structure must be included. The CUN6HB4A is a 365nm UVA source but not a UVC sterilization LED and should not be promoted for disinfection or germicidal application.
Do not look directly at the operating UV LED and avoid any unnecessary skin or eye exposure. Protective eyewear, shielding, warning label, and safe working procedures must be ensured during the test, assembly, and operation.
