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.

Dependent claims

Alighting decoration module, comprising:

a light guide plate, having at least one light incident surface, a first light exit surface, and a second light exit surface, wherein the first light exit surface and the second light exit surface connect the at least one light incident surface and are opposite to each other;
at least one light source, disposed corresponding to the at least one light incident surface of the light guide plate;
a plurality of first optical microstructures, disposed on the first light exit surface of the light guide plate and each of the plurality of first optical microstructures having a first surface facing the at least one light source, wherein a first angle between the first surface and the first light exit surface is greater than or equal to 40 degrees and less than or equal to 60 degrees;
and
a plurality of second optical microstructures, disposed on the second light exit surface of the light guide plate and each of the plurality of second optical microstructures having a second surface facing the at least one light source, wherein a second angle between the second surface and the second light exit surface is greater than or equal to 40 degrees and less than or equal to 60 degrees.
