Seoul Viosys UVC LED Bulbs CUD7GF1B
Product Details Description
The Seoul Viosys CUD7GF1B is a 275nm deep ultraviolet light emitting diode developed for UVC LED bulbs and custom UVC LED module projects. It has a 275nm wavelength, 1W power, 6.1V voltage, 100–250mA current, 16mW radiant power, and a 125° view angle. The product is suitable for air and water sterilization, fluorescent spectroscopy, chemical and biological analysis, and automotive interior applications.
This UVC LED is not a traditional mercury lamp or glass UVC bulb. It is a compact SMD deep UV LED component that can be welded onto aluminum or copper PCB boards. For SEO and buyer search matching, it can be positioned under UVC LED bulbs, but the product description should clearly explain that it is a 275nm UVC LED light-source component for module and system integration.
The CUD7GF1B has peak emission wavelengths from 270nm to 278nm. This range belongs to deep ultraviolet / UV-C output and is different from UVA LEDs such as 365nm, 385nm, or 395nm. The LED is sealed in a ceramic package with an optical transparent window and incorporates state-of-the-art SMD design with low thermal resistance.
For air sterilization applications, these UVC LED bulbs can be integrated into closed air-treatment modules, duct units, compact chambers, or equipment designs where airflow, exposure time, reflective structure, and safety shielding are controlled. The LED alone does not define sterilization performance; the complete device must be tested for dose, irradiance distribution, airflow rate, and target microorganism requirements.
For water sterilization applications, the CUD7GF1B can be used in properly designed water-path modules or UVC exposure chambers. Final performance depends on water clarity, flow rate, path length, LED quantity, optical window material, chamber reflectivity, temperature, and required UV dose. Any sterilization claim should be supported by system-level validation.
For fluorescent spectroscopy, chemical analysis, and biological analysis, this 275nm UVC LED can serve as a compact deep UV light source in analytical instruments, sample chambers, sensing devices, and laboratory modules. The 125° output angle is useful for broad local illumination, while optics or chamber design can be added when a more controlled light path is required.
For OEM and ODM projects, the CUD7GF1B can be mounted on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB can be used for many standard modules, while copper PCB can be selected when stronger heat transfer is needed. Custom options may include PCB shape, LED quantity, connector, wire, lens, quartz window, heat sink, housing, driver, and safety interlock design.
Thermal and electrical design are important for reliable UVC LED bulbs and module assemblies. Use a suitable constant-current driver, proper soldering process, appropriate PCB material, enough heat dissipation, and protection against electrical overstress. Engineers should verify board temperature, radiant output, optical transmission, and final application performance before mass production.
This product is a component-level UVC LED light source, not a complete finished lamp unless integrated into a final OEM design. A complete device should include a driver circuit, PCB board, heat sink, enclosure, optical window, shielding, warning label, and safety interlock when required. The product should not be used in open-exposure designs without proper UVC protection.
UVC radiation can injure eyes and skin. Never look directly at the operating LED, even briefly. Avoid direct skin exposure. Use protective eyewear, shielding, interlocks, warning labels, and safe operating procedures during testing, assembly, installation, and operation.

Is CUD7GF1B a Seoul Viosys UVC LED?
Yes. CUD7GF1B is a 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 build UVC LED bulbs, PCB modules, sterilization modules, spectroscopy tools, and analysis equipment, but it is not a traditional finished glass bulb by itself.
What wavelength does this LED use?
The CUD7GF1B uses a 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°, giving these UVC LED bulbs a wide deep UV emission pattern for compact module designs.
What package does this LED use?
The LED is sealed in a ceramic package including an optical transparent window.
Can this UVC LED be mounted on PCB boards?
Yes. It can be welded on 12mm, 14mm, 16mm, 20mm, or 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 available 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 integrated into a properly designed closed system with suitable 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 used in a properly engineered water-path module or exposure chamber. Final results must be verified at the complete system level.
Is this product safe for open handheld use?
No. This is a UVC / deep UV LED component. Open exposure can be hazardous to eyes and skin. A finished product must include shielding, warning labels, safety structure, and proper operating instructions.
Why is system-level validation important?
