Seoul Viosys UVC LED Bulbs CUD7GF1B
Product Details Description
Seoul Viosys CUD7GF1B is a 275nm deep ultraviolet light emitting diode made for UVC LED bulbs and customized UVC LED module project. Its specifications include wavelength 275nm, power 1W, voltage 6.1V, current 100–250mA, radiant power 16mW and view angle 125°. This deep UV LED product is intended for applications in air and water sterilization, fluorescent spectroscopy, chemical and biological analysis, and automotive interior products.
The CUD7GF1B UVC LED is not the mercury lamp or glass bulb type of UVC LED. It is the small SMD deep UV LED component which can be welded onto aluminum or copper PCB boards. In case of SEO and buyer search matching, the product can be placed in the section about UVC LED bulbs, however, its description should clarify that this is 275nm UVC LED light-source component.
The range of peak emission wavelengths of the LED is 270nm to 278nm. It refers to deep ultraviolet / UV-C output and differs from UVA LEDs with wavelengths 365nm, 385nm or 395nm. The LED is enclosed in a ceramic package with optical transparent window and has the modern SMD design with low thermal resistance.
Air sterilization application allows integrating these UVC LED bulbs in closed air-treatment modules, duct units, compact chambers or equipment where controlled air flow, exposure, reflective structure and shielding are installed. The LED does not define the sterilization performance, the whole device should be tested for dose, irradiance distribution, airflow rate and target microorganism.
In case of water sterilization, the product can be applied in the modules with water-path or in UVC exposure chambers. Performance depends on water clarity, flow rate, path length, number of LEDs, optical window material, chamber reflectivity, temperature and UV dose. Any sterilization claim should be backed up by the system-level validation.
In case of fluorescent spectroscopy, chemical analysis and biological analysis, the 275nm UVC LED can be applied as a deep UV light source in analytical instruments, sample chambers, sensors and laboratory modules. The 125° output angle allows broad local illumination while optics or chamber can be added in case of the controlled light path.
In case of OEM and ODM projects, the CUD7GF1B can be mounted on 12mm, 14mm, 16mm, 20mm or any other aluminum or copper PCB boards. The aluminum PCB can be used for most of standard modules, while copper PCB can be selected in case of stronger heat transfer. Custom solutions may include PCB design, number of LEDs, connector, wire, lens, quartz window, heat sink, housing, driver and safety interlock design.
Thermal and electrical design is crucial for reliable UVC LED bulbs and module assemblies. Suitable constant-current driver, proper soldering process, proper PCB material, heat dissipation and protection from the electrical overstress are necessary. Engineers should confirm the board temperature, radiant output, optical transmission and application performance before mass-production.
This product is a component-level UVC LED light source, it is not the finished lamp until being integrated in the final OEM design. The complete device should consist of driver circuit, PCB board, heat sink, enclosure, optical window, shielding, warning label and safety interlock in case of its necessity. The product should not be used in open-exposure designs without proper UVC protection.
UVC radiation can harm eyes and skin. Never look directly to the working LED even briefly. Avoid direct skin exposure. Use protective eyewear, shielding, interlocks, warning labels and safe operating procedures in case of testing, assembly, installation and operation.

FAQ
What are these UVC LED bulbs used for?
These UVC LED bulbs are used for disinfection, fluorescent spectroscopy, chemical and biological analysis and automotive interior applications when they are incorporated in the proper engineered module or device.
Is CUD7GF1B a Seoul Viosys UVC LED?
Yes. CUD7GF1B is the Seoul Viosys deep ultraviolet LED with 275nm wavelength and peak emission wavelengths from 270nm to 278nm.
Is this product a complete UVC bulb?
No. It is a UVC LED light-source component. It can be used to produce UVC LED bulbs, PCB modules, sterilization modules, spectroscopy devices and analysis equipment, however, it is not the finished glass bulb on its own.
What wavelength does this LED use?
The CUD7GF1B uses 275nm wavelength with peak emission wavelengths from 270nm to 278nm.
What is the radiant power?
The radiant power is 16mW.
What is the electrical power?
The power is 1W according to the provided specification.
What is the voltage?
The voltage is 6.1V.
What is the current range?
The current range is 100–250mA.
What is the package size?
The package size is 3.5 x 3.5mm.
What is the view angle?
The view angle is 125° which gives wide deep UV emission pattern for compact module designs of these UVC LED bulbs.
What package does this LED use?
The LED is enclosed in the ceramic package with optical transparent window.
Can this UVC LED be mounted on PCB boards?
Yes. It can be welded on 12mm, 14mm, 16mm, 20mm or any other aluminum or copper PCB boards according to the final module design.
Do you provide OEM or ODM UVC LED modules?
Yes. OEM and ODM service is provided for UVC LED bulbs, custom UVC LED module boards, sterilization modules, fluorescent spectroscopy modules, analytical light-source boards and other deep UV LED assemblies.
Can this product be used for air sterilization?
Yes. It is designed for air sterilization applications when it is incorporated in the properly designed closed system with appropriate UV dose, airflow control, shielding and safety design.
Can this product be used for water sterilization?
Yes. It is designed for water sterilization applications when it is used in the properly engineered water-path module or exposure chamber. The final results must be confirmed on the system level.
Is this product safe for open handheld use?
No. This is the UVC / deep UV LED component. Open exposure is harmful to eyes and skin. The finished product must have the shielding, warning labels, safety structure and proper operating instructions.
Why is the system-level validation important?
The sterilization performance depends on UV dose, exposure time, number of LEDs, optical design, distance, airflow or water flow, chamber structure and target organisms. Specification of the LED alone cannot guarantee the final disinfection result.
