UVA LED Module/System

Q: What scenarios are UVA modules mainly suitable for?

A: They are ideally suited for core applications including UV curing (e.g., PCB, 3C components, ink/adhesive curing), phototherapy tanning, anti-counterfeiting inspection, and mosquito attraction. Power ratings can be customized according to your specific requirements and irradiation area.
Q: Can the wavelength of UVA modules be customized? For example, 365nm/395nm?

A: Yes, we support customization of any wavelength within the 320–430nm range. Common wavelengths including 365nm, 385nm, 395nm and 405nm are standard models available for fast delivery.
Q: My curing equipment requires multi-module splicing. Can the light intensity consistency of each module be guaranteed?

A: Absolutely! The light intensity deviation of mass-produced modules is controlled within ±5%. We can also provide a unified driver solution to ensure uniform irradiation after splicing.
Q: What is the service life of UVA modules? Is light decay significant?

A: Under normal temperature and rated operating conditions, the service life is ≥10,000 hours, with light decay of less than 20% after 10,000 hours, meeting the long-term operation requirements of industrial equipment.
Q: Can you provide curing effect tests for UVA modules? For example, testing with a specific type of adhesive?

A: Yes! Simply provide your adhesive samples, and we can simulate your equipment operating conditions to test curing time and effect, and provide a detailed test report.
