Seoul Viosys UVC LED 275nm CUD7GF1A

Seoul Viosys CUD7GF1A is a 275nm UVC LED that is specifically designed for deep ultraviolet applications in small size, SMT assembling and module integration stability. The specifications include 0.183W power, 6.1V voltage, 30mA current, 5.5mW radiant power, and 120° view angle. The product can be used in disinfection, fluorescent spectroscopy, chemical analysis, biological analysis, and automotive interior applications.

The LED has peak emission wavelengths from 270nm to 278nm. This spectral range is typical for the deep ultraviolet / UV-C radiation output and differs from 365nm, 385nm, or 395nm UVA LEDs. The CUD7GF1A is designed for engineering and analytical systems and cannot be used for common visual inspection or blacklight applications.

The LED is housed in a ceramic package with an optical transparent window. The product includes the latest SMD technology and low thermal resistance. The dimensions of 3.5 x 3.5 x 1.2mm enable engineers to design compact UVC LED modules, prototype boards, analysis fixtures, and controlled exposure devices.

In case of disinfection-related equipment, this uvc led should be installed in a closed or shielded system with appropriate optical, thermal, and safety design. The performance of the disinfection is defined by parameters such as UV dose, exposure time, LED quantity, distance, target organism, chamber reflectivity, airflow or water flow, and safety structure. The LED specifications alone cannot guarantee the completion of the sterilization process.

In case of 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. Parameters such as optical path design, window material, exposure distance, driver current, thermal conditions, and sample type should be validated in the entire system.

The 120° beam angle gives this uvc led a wide local emission capability. This feature makes the product suitable for compact exposure chambers or module boards with broad illumination requirements. In case of narrow light path requirements, engineers can use quartz windows, reflectors, lenses, or chamber structure to manage UV distribution. UV distribution.

For OEM and ODM projects, the CUD7GF1A can be welded on 12mm, 14mm, 16mm, 20mm, or other aluminum or copper PCB boards. The aluminum PCB can be used in most compact module designs, while the copper PCB can be used for heat transfer optimization. The product can be supplied as a component or assembled in custom LED modules.

Thermal and electrical design is critical even at 30mA. Use proper constant-current driver, appropriate soldering process, stable PCB structure, and protection against electrical overstress. Engineers should validate board temperature, radiant output, optical transmission, and application performance in the final device before mass-production.

This product is a component-level uvc led and not a complete lamp. A complete device should include a driver circuit, PCB board, housing, optical window, shielding, wiring, connector, warning label, and safety interlock when necessary. The CUD7GF1A should not be used in open-exposure products without appropriate UVC safety protection.

UVC radiation is harmful to eyes and skin. Do not look directly at the operating LED even for a brief time. Do not expose the skin to the UVC. Use protective eyewear, shielding, interlocks, warning labels, and safe working procedures during testing, assembly, installation, and operation.
