Abstract

This paper presents an optical design of a dental light that meets the regulation of ISO 9680. The designed light pattern on the target is an elliptical shape with uniform illumination. Moreover, the real module contains four optical modules, and is operated at 9Wand performs a maximum illuminance of 42,010 lx. In order to reduce the correlated color temperature (CCT) variation, we replace the original white light-emitting diode with a new one, which has an extremely low angular CCT derivation. Accordingly, the CCT variation is reduced to 232 K from 1323 K of the original module.
