Abstract: A lighting decoration module includes an LGP, at least one light source, and first and second optical microstructures. The LGP has at least one light incident surface and first and second light exit surfaces that are opposite to each other and connect the light incident surface. The light source corresponds to the light incident surface. The first optical microstructures are disposed on the first light exit surface and each has a first surface facing the light source. A first angle between the first surface and the first light exit surface is within a range from 40-60 degrees or 15-35 degrees. The second optical microstructures are disposed on the second light exit surface and each has a second surface facing the light source. A second angle between the second surface and the second light exit surface is within a range from 40-60 degrees.
