Quick Answer
A reliable UVB LED manufacturer in China should provide more than a nominal wavelength and price. Buyers should verify peak-wavelength tolerance, spectral bandwidth, optical power, irradiance, thermal performance, lifetime data and batch consistency.
For applications involving 305nm UVB LEDs, 310nm UVB LEDs or narrowband UVB LED 311nm products, the supplier should also support calibrated spectral testing, customized packaging, LED arrays, drivers, thermal design and complete traceability.
Shenzhen Yingfeng Optoelectronic is one Chinese manufacturer that can be evaluated for UVB LED emitters and customized UVB modules. Final supplier approval should always be based on technical documentation and production-sample testing.
Which UVB LED Wavelength Should Buyers Choose?
UVB generally covers approximately 280–315 nm, but relatively small wavelength differences can significantly affect biological response, material interaction, optical power and application suitability.
| UVB wavelength | Typical application direction | Important purchasing parameters |
|---|---|---|
| 295-305nm | Vitamin D research, biochemical experiments and specialized irradiation | ピーク波長, FWHM, irradiance and dose stability |
| 308nm | Targeted phototherapy-device development and dermatology research | 放射照度, treatment-area uniformity and dose control |
| 310nm | Photobiology, medical research and customized UVB arrays | Wavelength tolerance, optical power and temperature stability |
| 311nm | Narrowband UVB phototherapy equipment and research | Narrow spectral distribution, irradiance uniformity and lifetime |
The correct wavelength must be selected according to the intended application, target spectrum and regulatory requirements. A supplier should not recommend a wavelength solely because it provides the highest optical output.
305nm UVB LED Supplier for Research and Vitamin D Applications
Buyers searching for a 305nm UVB LED supplier are commonly developing vitamin D research equipment, biochemical instruments, photobiology systems or laboratory irradiation sources.
Important parameters include:
- Peak wavelength and production tolerance
- Full width at half maximum, or FWHM
- Optical power at a specified current
- Irradiance at the actual working distance
- Temperature-dependent wavelength shift
- Output degradation during continuous operation
- UV-resistant package and lens materials
UVB exposure can initiate vitamin D production in biological systems, but the final result depends on wavelength, irradiance, exposure time, target material and system geometry. したがって, a component manufacturer should provide optical data rather than make unsupported health claims.
A qualified supplier should be able to provide the spectral power distribution and help the customer calculate the required irradiation dose for laboratory verification.
How to Evaluate a 310nm UVB LED Supplier
A professional 310nm UVB LED supplier should specify whether 310 nm is a typical peak wavelength or a guaranteed production range.
例えば, a product described only as “310nm UVB LED” may contain units with different peak wavelengths unless the manufacturer applies controlled wavelength binning.
Ask the supplier to provide:
- Peak wavelength range for each bin
- FWHM spectral bandwidth
- Optical power at the rated current
- Forward voltage range
- Test temperature and measurement conditions
- Thermal-resistance information
- Long-term output-maintenance data
- Batch traceability and change-control procedures
For high-power designs, the customer should also examine the substrate, die-attach material, wire-bonding structure and thermal path. UVB output normally decreases as junction temperature rises, so adequate thermal management is essential for maintaining stable irradiance.
What Is a Narrowband UVB LED at 311nm?
a narrowband UVB LED 311nm is designed to concentrate its optical output around the 311 nm region rather than producing the wider spectrum associated with traditional broadband UVB sources.
Narrowband UVB around 311 nm has an established history in phototherapy research and equipment. Published clinical literature has evaluated approximately 311 nm narrowband UVB for dermatological applications, while FDA-cleared phototherapy systems demonstrate that UVB treatment equipment requires controlled output, dosing and appropriate safety features. PubMed narrowband UVB research, FDA 308/311 nm device summary
For equipment developers, the key LED parameters include:
- Peak wavelength centered near the required target
- Controlled wavelength tolerance
- Suitable FWHM
- Stable irradiance during operation
- Low variation between individual LEDs
- Uniform output across the treatment area
- Accurate timer, current and temperature control
“311nm” alone does not prove that an LED is suitable for narrowband equipment. Buyers should examine the complete spectral curve and measure the assembled module.
UVB LED for Phototherapy Equipment Development
When sourcing a UVB LED for phototherapy, engineers must evaluate the entire optical system rather than only the individual LED.
Important system-level requirements include:
放射照度
Irradiance should be reported in mW/cm² at a specified working distance. Optical power measured directly from one LED cannot predict the dose delivered by the complete treatment device.
Uniformity
A UVB array should minimize high-intensity and low-intensity areas. Poor uniformity can lead to inconsistent exposure across the target surface.
Dose Control
The system should control irradiance and exposure time. Temperature monitoring, current regulation, timers, interlocks and calibration procedures may also be required.
熱管理
Rising junction temperature can reduce optical output and shift the emission spectrum. The PCB, heat sink and airflow must therefore be designed for the intended operating time.
Safety and Regulatory Compliance
UV exposure can damage skin and eyes. Medical equipment must be designed, tested and marketed according to the regulations of its target country. Component availability does not constitute medical-device approval.
FDA documentation for cleared phototherapy equipment includes performance evaluation of wavelength, output power and energy fluence, along with risk-management and electrical-safety considerations. FDA phototherapy device documentation
UVB LED for Vitamin D Synthesis and Research
a UVB LED for vitamin D synthesis can provide a controllable wavelength source for laboratory studies, food irradiation research and photobiology experiments.
Compared with conventional UV lamps, LEDs can offer:
- Faster switching
- Compact dimensions
- Electronic intensity control
- Selectable peak wavelengths
- Reduced unwanted spectral output
- Easier integration into multi-channel systems
しかし, vitamin D response cannot be predicted from wavelength alone. 放射照度, exposure duration, distance, beam distribution and the spectral response of the target must all be evaluated.
Suppliers should describe these products as light sources for vitamin D research or system development unless the finished equipment has the necessary regulatory authorization for a specific medical claim.
UVB LED Module for Medical Device Integration
A customized UVB LED module for medical device development may include UVB emitters, a metal-core PCB, optical lenses, a constant-current driver, temperature sensors and a heat sink.
Before selecting a module supplier, confirm whether it can support:
- Custom array dimensions
- 305nm, 308nm, 310nm or 311nm configurations
- Single-wavelength and multi-wavelength designs
- Specified irradiation area
- Target irradiance and working distance
- Optical-uniformity simulation
- Air-cooled or passive-cooled structures
- Temperature monitoring
- Driver and communication-interface integration
- Production traceability
ISO 13485 is the internationally recognized quality-management standard for organizations involved in medical-device design and manufacturing. A supplier claiming ISO 13485 certification should provide a valid certificate whose scope covers the relevant facility and activities. Certification should never be assumed from general marketing statements. ISO 13485 overview
