uvc led Seoul Viosys UVC 275nm CUD7GF1A
Product Details Description
The Seoul Viosys CUD7GF1A is a 275nm uvc led developed for deep ultraviolet applications that require compact size, SMT assembly, and stable module integration. It has 0.183W power, 6.1V voltage, 30mA current, 5.5mW radiant power, and a 120° view angle. The product is suitable for disinfection, fluorescent spectroscopy, chemical analysis, biological analysis, and automotive interior applications.
This uvc led has peak emission wavelengths from 270nm to 278nm. This spectral range belongs to deep ultraviolet / UV-C output and is different from 365nm, 385nm, or 395nm UVA LEDs. The CUD7GF1A is designed for engineered systems and analytical tools rather than ordinary visible inspection or blacklight applications.
The LED is sealed in a ceramic package including an optical transparent window. It incorporates a state-of-the-art SMD design and low thermal resistance. The 3.5 x 3.5 x 1.2mm size helps engineers build compact UVC LED modules, prototype boards, analysis fixtures, and controlled exposure devices.
For disinfection-related equipment, this uvc led should be integrated into a closed or shielded system with proper optical, thermal, and safety design. Final disinfection performance depends on UV dose, exposure time, LED quantity, distance, target organism, chamber reflectivity, airflow or water flow, and safety structure. The LED specification alone does not guarantee a finished sterilization result.
For fluorescent spectroscopy, chemical analysis, and biological analysis, the CUD7GF1A can be used as a compact 275nm deep UV source in sample chambers, sensing devices, laboratory tools, and analytical instruments. Optical path design, window material, exposure distance, driver current, thermal conditions, and sample type should be validated in the complete system.
The 120° beam angle gives this uvc led a wide local emission profile. This makes it useful for compact exposure chambers or module boards where broad illumination is required. If the application needs a more defined light path, engineers can use quartz windows, reflectors, lenses, or chamber structures to manage the final UV distribution.
For OEM and ODM projects, the CUD7GF1A can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. Aluminum PCB can be used for many compact module designs, while copper PCB can be selected when stronger heat transfer is required. The product can be supplied as a component or assembled into customized LED modules.
Thermal and electrical design remain important even at 30mA. Use a suitable constant-current driver, correct soldering process, stable PCB structure, and protection against electrical overstress. Engineers should verify board temperature, radiant output, optical transmission, and application performance inside the final device before mass production.
This product is a component-level uvc led, not a complete finished lamp. A finished device should include a driver circuit, PCB board, housing, optical window, shielding, wiring, connector, warning label, and safety interlock when required. The CUD7GF1A should not be used in open-exposure products without proper UVC safety protection.
UVC radiation can injure eyes and skin. Do not look directly at the operating LED, even briefly. Avoid direct skin exposure. Use protective eyewear, shielding, interlocks, warning labels, and safe working procedures during testing, assembly, installation, and operation.
