Optimal Optical Design of UV-LED Curing System with High Illumination and Luminance Uniformity

In this paper, we propose a design of LED UV-curing system for automated industrial production lines. The main novelty of this design is the application of compact packaged UV-LED module. The optical system uses conventional lenses rather than specially designed lens or reflectors to collimate the rays, saving material costs and making for easier mounting. Through the analysis and calculations, the optical design of the LED UV-curing system is optimized. The experimental results indicate that our design in this paper have significant advantages in illumination intensity (>1.5W/cm
²
) and uniformity (>0.8) over traditional UV-curing systems. The total power consumption is only 1.6KW.
