We fabricated ultraviolet-light-emitting diodes(LEDs) for use in a curing-apparatus, by using LED chips with 365-nm, 380-nm, 405-nm wavelengths in T1 and SMD type packages. The optical power and the curing ability of the fabricated LEDs were analyzed. Of all the fabricated LEDs, we reconstructed the 405-nm LED using optical simulation tools; then, we designed an optimal optic system with the reconstructed LED. Finally, we used the UV LED based on the designed data to make an optical curing system, and we analyzed the characteristics of that prototype.
