LIGHTING APPARATUS WITH CORRESPONDING DIFFRACTIVE OPTICAL ELEMENT

摘要

A lighting apparatus includes a laser source module and a diffractive optical module. The laser source module emits a laser beam. When the laser beam is operated in a transverse mode or a multi-transverse mode, the laser beam has a first laser beam pattern. The diffractive optical module is arranged in front of the laser source module or at a location that receives the laser beam, so that the laser beam is irradiated on the diffractive optical module. The diffractive optical module includes a first structure pattern corresponding to the first laser beam pattern. After the laser beam is diffracted by the first structure pattern, a first structured light with a first structured light pattern is generated.
