uv led chip 365nm Seoul Viosys UVA CUN6GB1A ultraviolet module customizable
Product Details Description
Seoul Viosys CUN6GB1A uv led chip 365nm is a high power uv led chip 365nm designed for industrial and scientific purposes that need a small size, high radiant power, and well-controlled beam area. With a wavelength of 365nm, radiant power of 1400mW, voltage of 3.7V, operating current of 1000mA, and a 65° viewing angle, this led is suitable for developers of UV-A curing units, printers, coating machines, inspecting devices, UV torches, and UV LED modules.
Seoul Viosys CUN6GB1A is one of the best members of the CA3535 near UV LEDs series. Its construction includes the SMT package and low thermal resistant materials which make it convenient to use in high-current PCB UV light engines. The package size 3.5 x 3.5 x 2.5mm allows creating small-size units with powerful 365nm radiation without using the big lamp structure.
The wavelength of 365nm is very common in UV-A curing and fluorescence based detection. In comparison with a larger wavelength 395nm, 365nm often creates a better fluorescence effect and has less visible interference in purple light in many inspections. This uv led chip 365nm may be used in counterfeit detection, security checks, fluorescence photography, crime inspection, oil leakage detecting, and UV torches.
In manufacturing processes, this uv led chip 365nm may be applied in the construction of UV curing modules, printers, coating equipment, adhesive curing devices, and dental curing devices if the material responds to 365nm UV-A radiation. The performance will depend on the material chemistry, distance of UV light source, optics of the system, driving current, thermal conditions, and needed UV dosage.
The 65° viewing angle allows obtaining a good optical profile for this model. It is more focused than wide-angle 115° and 120° LEDs but not as tightly focused as 35° spot-type UV LEDs. This property makes the Seoul Viosys CUN6GB1A suitable for UV flashlight heads, portable inspection devices, medium area curing modules, coating inspection devices, and small exposure units.
In case of developing custom UV devices, the CUN6GB1A may be welded on 12mm, 14mm, 16mm, 20mm, and any other aluminum and copper PCBs. The aluminum PCB may be used in many standard UV modules constructions, but if more powerful thermal transferring is needed, it is recommended to use the copper PCB. The LED may be supplied as a component or may be assembled into UV torch modules, curing modules, inspection lights, and any other custom-made UV LED products.
The thermal design is an important parameter for a 1000mA UV LED. For stable and long-term work it is necessary to use the right constant-current driver, right soldering technology, right PCB material, and sufficient heat dissipation. The engineers have to check the temperature of the board, radiant output, beam profile, and application performance in the final product before mass production.
This product is a component of UV LED, but not a whole lamp. In the finished device there should be the driver circuit, PCB board, heat sink, housing, optical lens or reflector, wires, switch, and safety elements. The CUN6GB1A is 365nm UVA light source, not a UVC sterilization LED and should not be advertised for disinfection or germicidal application.
Do not stare into the working UV LED and do not expose your skin or eyes into the beam. Use protective eyewear, shielding, warning labels, and safe work procedures during the testing, assembling, and operation of this UV LED.
