Abstract
A light source assembly provides an illumination beam and the light converging element is disposed on a transmission path of the illumination beam. A light converging element has a top end and a bottom end opposite to the top end. The light converging element is gradually reduced from the bottom end to the top end. The top end is opposite to the light source assembly and has a cavity. The illumination beam is incident into the light converging element from the cavity and exits the light converging element from the bottom end.
