This paper presents a simple, low-cost, long-lasting UV-LED-based light source with uniform light intensity using a checkerboard half-mirror positioned within inverse L-shaped UV-LED arrays. The light rays from the top UV-LED array passed through the transparent portions of the checkerboard half-mirror, while the light rays from the side UV-LED array were reflected on the remaining opaque portions at right angles. Thus, uniform light intensity was achieved on the bottom area. Using the developed UV-LED light source, we fabricated microstructures with uniform shapes on a large area, thereby showing feasible applications for MEMS fabrication.
