Abstract:
1. A light source structure of backlight module, installed on a lateral side of a light guide plate, comprising: a casing, installed on a side of the light guide plate, and having a containing space therein, and an opening disposed on a lateral side of the casing and interconnected with the containing space; a plurality of light source generators, installed in the containing space, and each light source generator being installed onto a substrate through a light emitting component, and a reflector being installed on the light emitting component, a light pipe being connected to an end where the reflector and the substrate are connected; a first reflecting element, installed in the containing space, and having an oblique surface perpendicular to a plurality of light source generators, and the oblique surface of the first reflecting element disposed corresponding to the opening; a second reflecting element coplanar with the first reflecting element, installed on a lateral side of the light guide plate, and having an oblique surface disposed corresponding to the light guide plate, and the oblique surface of the second reflecting element disposed corresponding to the opening, and an inclination between the oblique surface of the second reflecting element and the oblique surface of the first reflecting element being in a range from about 90 degrees to about 180 degrees; thereby, the light pipe focuses and converts the spot light source of the light emitting component into a linear light source to be projected onto the oblique surface of the first reflecting element, and the oblique surface converts the linear light source into a planar light source to be projected onto the oblique surface of the second reflecting element through the opening, and the oblique surface of the second reflecting element guides the planar light source into the light guide plate.
