CROSS-SHAPED LIGHT GENERATING APPARATUS

摘要

A cross-shaped light generating apparatus comprises a laser source producing diverging laser and a light curving sheet (10) disposed at the transmitting end of the laser source. The light curving sheet comprises at least a group of transverse concave grooves (11) and at least a group of longitudinal concave grooves (12). Light generated from the laser source is refracted by the transverse concave grooves and the longitudinal concave grooves and transmitted through the light curving sheet, and a cross-shaped light is irradiated.
