How to Choose the Right Array LED UV Module
-
Define the Application
Determine the most suitable use case from the following:
-
UV Curing: inks, coatings, adhesives in industrial and commercial printing, PCB coating, and packaging.
-
Disinfection/Sterilization: air, water, or surfaces cleansing.
-
Fluorescence Excitation: biological imaging or quality control inspection.
-
Photolithography: semiconductor or PCB exposure.
-
Machine vision/sorting systems.
All these processes have different requirements for wavelength selection, power and cooling systems, and…

The Right Wavelength
| Wavelength | Ideal For |
|---|---|
| 265–280 nm (UV-C) | Germicidal / Disinfection (air, water, surfaces) |
| 300–320 nm (UV-B) | Phototherapy, lab use |
| 365 nm (UV-A) | UV curing, industrial inspection, NDT |
| 395–405 nm | Low-cost curing, scorpion/stain detection |
365 nm is the most common for industrial curing and precision inspection.
Only UV-C 265–280 nm lamps are permitted for sterilization.
-
Measurement of Total Radiant Power as an Output
Optical power settings can be set to high (W or mW/cm²) to enable quicker and deeper curing along with stronger fluorescence.
Make sure to check for uniform intensity across the array to confirm consistent performance.
For curing, typical targets are:
-
Greater than 1,000 mW/cm² for high-speed production lines for laser-processed products.
-
300 – 800 mW/cm² for general or slower curing applications.
-
Spatial Characteristics and Geometric Configuration of the Radiation Source
-
Linear Arrays: Suitable for curing by conveyor and for strip inspection.
-
Matrix Arrays: Suitable for broad area curing and panel exposure.
Make certain that the active emitting area conforms with your part or inspection surface.
If scalability is required, consider modular stacking.
-
Thermal Management System
-
Passive cooling is applicable for low-power modules (limited range).
-
Active air-cooled is common in mid-power applications.
-
Water cooled is best for high intensity continuous duty cycle operation.
Look for aluminum MCPCB, heat sinks or components with integrated fans.
-
Electrical Interface
Confirm:
-
Input voltage (12V, 24V, or 48V DC)
-
Current draw requirements
-
Need for constant current driver
-
Included drivers versus need for external control units
-
Control and Integration
Look for:
-
PWM dimming or other forms of dimming control
-
Trigger/sync inputs for automation
-
Digital interfaces like RS485, CAN or MODBUS in higher-level systems
-
Product Robustness and Lifetime
High output power UV LEDs from reputable manufacturers should have:
-
10,000–50,000 hours lifespan
-
LM-80 testing or MTTF data
-
Dust, humidity, or water resistant enclosures with an IP rating.
-
Additional Options
Changeable optics such as:
-
Lenses, diffusers, reflectors
-
UV-pass filters for blocking non-target wavelengths
-
Calibration for uniformity or spectral binning over-calibration
-
Protection against overheating and diagnostics on-board
