Dual-Wavelength UVC LED Strip Lights 275nm + 395nm
Product Details
Dual-Wavelength UV Strip for OEM Integration
The yoyouv LS-3535-60D-12V-UVC+UVA is intended for manufacturers, engineers, and system integrators needing dual-wavelength UVC LED strip lights for control ultraviolet equipment. This product integrates 275nm UVC and 395nm UVA light on the five-meter SMD3535 strip.
The 275nm and 395nm wavelengths are able to create two different ultraviolet bands in one element. These UVC LED strip lights create one linear platform for development dual-band equipment.
This product may be tested for systems requiring UVC light and UVA fluorescent indication, visualization, inspection, or photochemistry support. The performance has to be validated in the finished equipment for the target application and cycle.
60 LEDs per Meter
There are 60 SMD3535 LEDs in each meter of this product. The UVC LED strip lights maintain 60 LED/m configuration across the entire length of this product.
This configuration allows distributing the emitters along the PCB and allows the engineers positioning ultraviolet light emission across the linear chamber, cabinet, duct, channel, or treatment space.
These UVC LED strip lights use 120-degree light emission angle. The irradiance at the target depends on the installation distance, LED spacing, reflection, enclosure material, operating temperature, voltage stability, and optical design of the equipment.
12V and 24V System Options
This product works from 12V or 24V input and operates from 14W/m. Voltage option has to be confirmed prior to the approval of the samples and mass production as the PCB circuits and power supply have to match.
When the length of long UVC LED strip lights has to be calculated, the power supply capacity, wire sizing, connector rating, voltage drop, and power injection points have to be analyzed prior to usage.
Five-Meter SMD3535 Construction
This strip has dimensions 5000 × 10 × 4mm. The five-meter length allows using the product in various customized equipment layouts, while the 10mm wide PCB allows installing the product in appropriate profiles or narrow mounting areas.
The specification does not define the cutting interval and minimum bending radius. Please, confirm this information prior to cutting, bending, folding, or mounting the UVC LED strip lights. Do not make sharp bends and put mechanical loads on LEDs, solder joints, and connections.
4oz Copper PCB
A 4oz copper PCB is used to improve electrical and thermal conductivity. This does not mean that there is no need to evaluate thermal performance of the UVC LED strip lights depending on the installation.
The increased thickness of the copper layer does not mean that there is no need for thermal management. Installation of the strip on the heat-conductive surface has to be evaluated depending on the installed length, duty cycle, enclosure temperature, and airflow.
The excessive temperature of junction or PCB may affect output performance and the service life. Thermal testing has to be performed in the final enclosure rather than in the open-air sample test.
IP20 or Custom Waterproof Configuration
The standard protection level is IP20. Standard IP20 UVC LED strip lights are made for protected installation and should not be exposed to water, condensate, conductive dust, or outdoors.
The waterproofing can be customized. Any coating, sleeve, encapsulation, or optical cover have to be checked for 275nm and 395nm transmittance, thermal influence, aging, chemical resistance, and water tightness.
Custom Connection Options
The electrical connection can be customized to fit OEM assembly requirements. Custom UVC LED strip lights can be supplied with project-specific connection options.
Buyers can indicate the connector type, wire length, wire gauge, power entry point, polarity markings, and preferred terminal configuration.
To perform an accurate project evaluation, please indicate the target voltage, installed length, operating cycle, enclosure dimensions, mounting surface, environmental conditions, and order volume in the request for the sample or quotation.

Applications
1. Closed Air Treatment Devices
Such strips of UVC LED lights could be evaluated for installing in closed air treatment units, ventilation parts, and recirculating air treatment equipment. Air flow, irradiation distance, dwell time, temperature and target dose have to be validated for the completed unit.
2. Closed Surface Treatment Cassettes
UVC LED strips could be installed in closed cabinets, boxes, conveyors and controlled surface treatment equipment. Several installing locations could help reduce shadow zones, but performance of such treatment should be measured on the treated surface.
3. Water Treatment Units
UVC LED strips could be considered for water treatment units only if isolated from direct contact with the water by the suitable UV-transmitting structure. Whole assembly needs to be made waterproof, thermally managed, electrically isolated, flow-tested and dose-validated.
4. Systems for Excitation and Inspection
395nm UVA light source could be used for fluorescence excitation, positioning checks, inspection, and indication of operation in compatible equipment. Performance of such application depends on the fluorescent substance and optical parameters.
5. Custom Laboratory and Industrial Equipment
UVC LED strips could be used for installing in testing chambers, research equipment, analytical devices, and special OEM devices requiring a narrow and distributed ultraviolet source with customizable wiring and environmental protection.
Application Notes
Avoid Direct UV Exposure
During operation of UVC LED strip lights avoid any exposure of the eye and skin to ultraviolet light. UVC LED strip should be installed in closed housing or shielding cabinet and use access interlocks, warning signs, timers, sensors or other control equipment.
Disconnect the Power Before Installing
Disconnect power before installing, checking, cleaning, cutting, soldering or replacing the connectors. Check polarity and 12V or 24V version of the strip before powering.
Use Suitable Thermal Dissipation
Don’t operate full five-meter roll when tightly coiled. Test thermal dissipation under the actual installation length and duty cycle. Use the suitable aluminum profile, heat spreader or other mounting structure if required by thermal design.
Consider IP20 Limitation
IP20 is not waterproof. Don’t install the standard version where it could contact water or condensation. Waterproofing should be customized and tested for UV transmission and long-term stability of material.
Measure UVC and UVA Emission Separately
Don’t rely on visible 395nm emission as a proof of 275nm UVC emission. Use the wavelength-specific and calibrated measuring equipment for validation of spectral emission, irradiance and delivered dose.
Validate the Completed Equipment
Don’t claim specific microbial reduction from wavelength and electrical power. Validation should be performed with target microbe, target surface, liquid, air flow, distance, exposure time and complete equipment configuration.
