In UV curing systems, the performance of the light source directly determines curing efficiency and quality. The key parameters include:

1. Wavelength: Typically ranges from 300–450 nm. Different substrates and applications require specific wavelengths to achieve optimal curing.

2. Intensity: The amount of energy delivered per unit time and area, measured in W/cm² or mW/cm². Higher intensity allows faster curing.

3. Spectral Distribution: Different materials respond to different spectra. A well-matched spectral output ensures efficient curing results.

4. Irradiation Area: The effective coverage of the UV light, determined by the size and shape of the material to be cured.

5. Irradiation Angle: The incident angle of UV light on the surface, which affects curing uniformity and penetration depth.

6. Stability: Consistency in both intensity and spectral output is critical for maintaining reliable curing performance over time.

In summary, the key parameters of UV curing light sources include wavelength, intensity, spectral distribution, irradiation area, irradiation angle, and stability—all of which work together to ensure high-quality and efficient curing.
