UVB LED Modules

YOYO-UV is a professional UVB LED module manufacturer providing standard and custom UVB light sources for OEM equipment manufacturers, scientific instruments, phototherapy device development and specialized industrial applications.

Our UVB LED modules can be developed at commonly requested wavelengths such as 295nm, 308nm, 310nm and 311nm, depending on the requirements of the project. Custom wavelength, radiant power, PCB size, optical design, voltage, current and thermal structure are also available.

From a compact single-LED PCB to a high power UVB LED module or LED array, our factory provides flexible OEM and ODM solutions for prototype development and volume production.

308nm, 310nm and 311nm UVB LED Modules

UVB generally covers the wavelength range from about 280nm to 315nm.

Different wavelengths are selected for different optical and biological applications.

308nm UVB LED modules can be used as controlled UVB light sources in professional phototherapy equipment, research systems and specialized optical devices.

310nm UVB LED modules are suitable for UVB irradiation systems, analytical instruments, research equipment and custom light-source assemblies.

311nm UVB LED modules are especially relevant to narrowband UVB light-source development. They can be integrated into professional phototherapy equipment and laboratory systems that require a controlled narrow UVB spectrum.

The wavelength alone does not determine the performance of a finished system. Irradiance, radiant power, exposure area, working distance, optical distribution, exposure control and thermal management should also be considered.

UVB LED Modules for Phototherapy Equipment

One of the main applications for UVB LEDs is integration into professional phototherapy equipment.

Our UVB LED modules can be developed as light-source components for:

• Localized phototherapy devices
• Handheld professional equipment
• Desktop phototherapy systems
• Narrowband UVB equipment
• UVB research instruments
• Prototype medical-device development

For these applications, wavelength accuracy and output uniformity are especially important.

Depending on the design, we can customize LED quantity, PCB layout, irradiance, beam angle, optical lenses and cooling structure to match the required treatment or irradiation area.

Our UVB LED modules are supplied as components for equipment integration. They are not finished medical devices. The final equipment manufacturer is responsible for system validation, dose control, safety protection and applicable regulatory requirements.

UVB LED Modules for Scientific and Industrial Applications

UVB LED technology is also useful outside phototherapy equipment.

Typical applications may include:

• Scientific research
• Fluorescence and spectroscopy systems
• Chemical and biological analysis
• Material testing
• UV aging studies
• Photochemical research
• Optical sensing
• Laboratory irradiation systems
• Plant and horticultural research
• Controlled-environment agriculture research

Compared with traditional broad-spectrum UV sources, LEDs allow engineers to select a more specific wavelength and build compact UVB light-source assemblies around the equipment.

Custom High Power UVB LED Modules

Standard UVB LED boards do not fit every device.

As an OEM UVB LED module manufacturer, we can customize modules according to your mechanical, electrical and optical requirements.

Available customization can include:

• UVB wavelength
• Wavelength tolerance
• Radiant power
• Irradiance
• LED quantity and arrangement
• PCB dimensions and shape
• SMD or multi-chip configuration
• Aluminum PCB
• Copper PCB
• Ceramic substrate
• Voltage and operating current
• Beam angle
• Optical lenses
• Wiring and connectors
• Heat sinks
• Air cooling
• Mechanical housing

Round, square, rectangular, linear and other custom UVB LED boards can be developed according to the available installation space.

UVB LED PCB and Thermal Management

Although UVB LEDs are compact, thermal management remains important for stable operation.

Higher junction temperatures can affect LED output and long-term performance. The complete module should therefore be designed around the LED, PCB, driver and cooling structure rather than considering the UVB chip alone.

Depending on the required power level, we can use aluminum, copper or other suitable PCB structures.

For higher-output modules, additional heat sinks or active cooling may be required.

Our engineering team can evaluate PCB size, drive current, LED layout and thermal conditions during the OEM or ODM development process.

Optical Design for UVB LED Modules

The same UVB LED can produce very different irradiance patterns depending on the optical system.

We can provide different beam angles and optical configurations according to the required working distance and irradiation area.

A narrow beam can be useful when concentrated UVB output is required over a smaller target area.

A wider beam may be more suitable when the application needs broader and more uniform coverage.

For custom projects, tell us the target irradiation area and working distance so that the LED layout and optics can be designed together.

What Information Is Needed for a Custom UVB LED Module?

For a new custom UVB LED module, please provide as much of the following information as possible:

• Target wavelength
• Required radiant power or irradiance
• Working distance
• Irradiation area
• PCB dimensions
• Input voltage
• Operating current
• Beam angle
• Continuous or intermittent operation
• Cooling conditions
• Target application
• Required wiring or connector

If some parameters are not yet known, tell us the application, installation space and expected UVB output. Our engineers can recommend a suitable starting configuration.
