UVA LED Modules

YOYO-UV is a professional UVA LED module manufacturer providing standard and custom UV LED light sources for industrial equipment, UV curing systems, inspection devices and OEM product development.

Our UVA LED modules are available in common wavelengths including 365nm, 385nm and 395nm, with 405nm near-UV/violet modules also available for compatible curing applications. We can customize wavelength, radiant power, PCB size, LED quantity, optical design, voltage, current and cooling structure according to your equipment requirements.

From a small UV LED PCB to a high-power COB or LED array, our factory provides flexible OEM and ODM UVA LED module solutions for prototype development and volume production.

365nm, 385nm, 395nm and 405nm UV LED Modules

Choosing the correct wavelength is one of the most important steps when designing a UVA LED system.

365nm UVA LED modules are widely used for fluorescence inspection, UV curing, adhesive curing, coating, detection and other applications that require strong UVA excitation.

385nm UVA LED modules provide a practical light source for industrial curing, printing, coatings and UV-sensitive materials.

395nm UVA LED modules are commonly used in UV curing machines, printing equipment, resin curing, coatings and adhesive applications.

405nm UV LED modules are technically in the near-UV/violet region but are widely grouped with UVA curing products in industrial applications. They are commonly used with UV-sensitive resins, inks and photopolymers designed to respond to 405nm light.

The best wavelength depends on the absorption characteristics of the material being processed. For OEM projects, we recommend testing the UV light source with the actual ink, resin, coating or adhesive before finalizing the module.

UVA LED Modules for UV Curing

UV curing is one of the main applications for UVA LED modules.

Our UV LED curing modules can be integrated into equipment for:

• UV ink curing
• Adhesive and glue curing
• Coating curing
• Resin curing
• UV printing
• 3D printing
• Electronics manufacturing
• Automated production lines

A curing system should not be selected by electrical wattage alone.

Wavelength, radiant power, irradiance at the working surface, exposure time, working distance, optical design and curing area all affect the final result.

For industrial equipment manufacturers, we can develop compact or high power UVA LED modules according to the required irradiation area and process speed.

UVA LED Modules for Inspection and Detection

UVA light, especially around 365nm, is also widely used as an excitation source for fluorescence-based inspection.

Typical applications include:

• Fluorescence inspection
• Industrial leak detection
• Non-destructive testing systems
• Security and counterfeit inspection
• UV-reactive material inspection
• Optical inspection equipment
• Laboratory instruments

The required wavelength and optical output depend on the fluorescent material and the sensitivity of the inspection system.

Custom lenses and beam angles can be used when the application requires focused light, wider coverage or more uniform irradiation.

Custom High Power UVA LED Modules

Different equipment has different mechanical, electrical and optical requirements. A standard UV LED board may not fit every system.

As an OEM UVA LED module manufacturer, we can customize the complete module according to your design.

Available customization can include:

• 365nm, 385nm, 395nm and other wavelengths
• 405nm near-UV/violet options
• Custom radiant power and UV intensity
• PCB dimensions and shape
• LED quantity and layout
• COB, SMD or LED array structures
• Aluminum PCB
• Copper PCB
• Ceramic substrate
• Voltage and operating current
• Beam angle
• Optical lenses
• Wiring and connectors
• Heat sinks
• Air cooling
• Water cooling
• Mechanical housing

Round, square, rectangular, linear and other custom PCB structures can be developed according to the available installation space.

High Power UVA LED Module Thermal Management

Heat management becomes especially important as UV LED power increases.

A high power UVA LED module should be designed as a complete system rather than selecting the LED chip alone.

The PCB material, drive current, heat sink, airflow, water cooling and operating environment can affect junction temperature and UV output stability.

For compact applications, aluminum or copper PCB structures can provide an effective thermal path. Higher-power UV curing systems may require larger heat sinks, forced-air cooling or water cooling.

Our engineering team can help evaluate these factors during an OEM or ODM project.

What Information Do We Need for a Custom UVA LED Module?

To recommend or design the right module, please provide as much of the following information as possible:

• Required wavelength
• Required UV intensity or radiant power
• Irradiation area
• Working distance
• Available module dimensions
• Input voltage
• Application
• Continuous or intermittent operating time
• Cooling conditions
• Required beam angle
• Target ink, resin, coating, adhesive or fluorescent material

If you do not know all of these parameters, simply tell us the application and available installation space. Our engineers can help determine a suitable starting configuration.
