275nm + 395nm UVC Strip, 30 LEDs/m | yoyouv

Product Details

Purpose-Built Dual-Wavelength Component

The yoyouv LS-3535-30D-12V-UVC+UVA is a dual-wavelength UVC strip for manufacturers, laboratories, and engineering teams developing controlled ultraviolet equipment. Instead of using separate boards for UVC and UVA functions, this model places 275nm and 395nm output within one five-meter component.

The two wavelength bands can support different roles inside a completed system. The 275nm section can be evaluated as the UVC source, while the 395nm section may support fluorescence response, process observation, positioning, or status indication when suitable materials are present. The actual function of each band must be verified in the intended equipment.

30 LEDs per Meter

This UVC strip uses 30 SMD3535 LEDs per meter. The lower emitter density leaves more spacing between LED positions than a 60 LED/m configuration and gives designers another option for projects with different output distribution, electrical load, or component-cost targets.

Output uniformity at the working surface depends on strip placement, distance, reflectors, chamber geometry, surface shape, and the selected operating cycle. Prototype measurements should therefore be taken throughout the target area rather than at only one central point.

Electrical Design

The UVC strip is available for 12V or 24V input, with a specified working power of 7.2W per meter. The ordered voltage must match the power supply and control circuit. Applying an incorrect input may damage the strip or prevent normal operation.

For extended installations, calculate the total load from the connected length. Cable gauge, connector rating, voltage drop, power injection, switching device capacity, and power-supply headroom should be reviewed before assembly. The specification does not define maximum single-end feed length, so this value should be confirmed during project engineering.

Mechanical Format

The product measures 5000 × 10 × 4mm. Its five-meter format can be arranged inside compatible linear profiles, equipment walls, internal frames, test rigs, and enclosed processing zones. The specified emission angle is 120 degrees.

Do not assume that the board can be cut at any position. Cutting interval, solder-pad location, minimum bend radius, adhesive backing, and permitted bending direction should be confirmed before mechanical design. Avoid folding across an LED package or solder joint.

Spectrum and Optical Planning

The specified wavelengths are 275nm and 395nm, with a spectrum FWHM of 10nm. Because the two ultraviolet bands require different sensors and optical materials, spectral and irradiance measurements should be performed with instruments suitable for each wavelength range.

The UVC strip should be evaluated behind the same window, cover, sleeve, or protective material planned for the finished product. Materials that transmit 395nm UVA may not provide the same transmission at 275nm UVC.

PCB and Thermal Integration

A 4oz copper PCB is used to improve current conduction and distribute heat along the board. Thermal behavior still depends on installed length, mounting surface, ambient temperature, enclosure volume, airflow, and duty cycle.

For stable operation, mount the UVC strip to an appropriate heat-conductive structure when required by test results. Do not energize a long section while it remains tightly wound on the reel, as heat can accumulate between layers.

Protection and Connections

The standard waterproof rating is IP20. This version is intended for protected integration and should not be exposed directly to water, condensation, or conductive contamination.

Waterproof construction can be customized. The selected encapsulation, tube, coating, or window should be checked for transmission at both wavelengths, heat retention, sealing reliability, and resistance to long-term ultraviolet exposure.

Connection options are customizable. Buyers can specify wire length, connector model, polarity marking, cable exit direction, and power-entry position to reduce additional assembly work.

Technical Specifications

UVC Strip Applications

Enclosed Air-Processing Equipment

The UVC strip can be considered for controlled air channels, recirculation units, and enclosed treatment compartments. System testing should account for airflow speed, residence time, distance, shadowing, and delivered ultraviolet dose.

Surface-Treatment Chambers

Multiple linear sections may be positioned inside closed cabinets or processing chambers to distribute ultraviolet output across a target area. Complex surfaces and overlapping parts can create shaded zones, so coverage should be mapped in the completed fixture.

Water-System Components

The UVC strip may be evaluated as part of a sealed water-treatment assembly, but the standard IP20 version must not contact water. A compatible barrier, waterproof housing, electrical isolation, and verified thermal path are required.

Fluorescence and Process Inspection

The 395nm band of the UVC strip can be evaluated for fluorescence excitation or process observation with compatible dyes, coatings, inks, minerals, or inspection materials. Test the target material under actual optical conditions before finalizing the equipment.

Laboratory and OEM Development

The UVC strip provides a configurable linear platform for experimental chambers, analytical fixtures, prototypes, and specialized industrial systems that require both UVC and UVA functions.

UVC Strip Application Precautions

Prevent Direct Exposure

Operate the UVC strip only inside an appropriately controlled setup. Prevent direct exposure of eyes and skin, and design the finished equipment with shielding, access interlocks, warning labels, and operating controls suitable for the application.

Verify Both Wavelengths Independently

A visible response from the 395nm LEDs does not confirm 275nm output. Measure each band with calibrated instruments designed for the relevant wavelength range.

Use the Correct Voltage

Confirm whether the ordered UVC strip is the 12V or 24V version before wiring. Disconnect power before soldering, cutting, mounting, inspection, or connector replacement.

Manage Heat Along the Installed Length

Test PCB and enclosure temperatures under the actual duty cycle. Use an aluminum profile or another heat-spreading structure when thermal measurements show it is necessary.

Respect the IP20 Rating

Keep the standard version away from liquids and condensation. Customized waterproof protection must be verified for sealing, ultraviolet transmission, temperature, and material aging.

Validate Performance in the Final Device

Do not calculate treatment performance from wavelength and watts alone. Measure irradiance and dose at the target, then verify results using the intended process, exposure time, geometry, and operating conditions.
