Seoul Viosys UVB LED 310nm CUD1GF1A
Product Details Description
The Seoul Viosys CUD1GF1A is a 310nm uvb led developed for deep ultraviolet light-source applications where compact size, SMT assembly, and controlled UVB output are required. It has 0.12W power, 6.1V voltage, 20mA current, 1.5mW radiant power, and a 120° view angle. The product is suitable for disinfection, fluorescent spectroscopy, chemical analysis, and biological analysis applications.
This uvb led has peak emission wavelengths from 305nm to 315nm. The 310nm output falls in the UVB range and is different from 365nm, 385nm, or 395nm UVA LEDs. It is designed for specialized instruments and engineered modules rather than general blacklight, visible inspection, or consumer flashlight use.
The CUD1GF1A 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 3.5mm size helps engineers build compact UVB LED modules, prototype boards, test fixtures, and analytical light-source assemblies.
For fluorescent spectroscopy, this uvb led can be used as a compact 310nm excitation source in optical paths, sample chambers, or instrument modules. Final performance depends on the optical window material, sample type, exposure distance, lens or chamber design, driver current, thermal structure, and required signal level.
For chemical and biological analysis, the CUD1GF1A can be integrated into test equipment, sensing devices, laboratory fixtures, or board-level deep UV modules. Because UVB output is application-sensitive, engineers should validate irradiance, beam distribution, sample compatibility, and thermal conditions inside the complete system.
The provided application list includes disinfection. For disinfection-related equipment, this uvb led must be used only inside a properly engineered system with suitable shielding and system-level validation. Any final disinfection result depends on UV dose, exposure time, LED quantity, distance, chamber geometry, target organism, and safety design.
For OEM and ODM projects, the CUD1GF1A can be mounted 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 thermal transfer is required. The product can be supplied as a component or assembled into customized LED modules.
Although the operating current is only 20mA, thermal and electrical design still matter. Use a suitable constant-current driver, correct soldering process, stable PCB structure, and protection against electrical overstress. Engineers should verify radiant output, board temperature, optical transmission, and final application performance before mass production.
This product is a component-level uvb 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 CUD1GF1A should not be used in open-exposure products without proper UVB safety design.
UVB radiation can injure eyes and skin. Do not look directly at the operating LED. Avoid direct skin exposure. Use protective eyewear, shielding, interlocks, warning labels, and safe working procedures during testing, assembly, and operation.
