Side-edge backlight module

A side-edge backlight module, comprising a backplane, a backlight source arranged inside the backplane, and a light guide plate arranged inside the backplane, the backplane and the backlight source receiving an aluminum-extruded heat sink arranged therebetween, the aluminum-extruded heat sink comprising a first mounting section and a second mounting section perpendicularly connected to the first mounting section, the backlight source being mounted on the first mounting section, the first mounting section forming a slope surface at a location close to the second mounting section, the slope surface being s arranged to extend from connection of the first and second mounting sections toward the backlight source;

• wherein the slope surface forms an included angle of 3-8° with respect to a vertical plane;
• wherein the slope surface is formed by means of inclined pressing;
• wherein the backlight source comprises a PCB, a plurality of LED lights mounted on and electrically connected to the PCB, and a rectifier mounted on and electrically connected to the PCB;
• wherein the second mounting section forms a receiving cavity corresponding to the rectifier;
• wherein the backplane comprises a bottom board and a side board perpendicularly connected to the bottom board, the first mounting section being positioned against the side board, the second mounting section being fixed by bolts to the bottom board;
• wherein the second mounting section has an end that is distant from the first mounting section and forms a raised portion, the light guide plate being supported on the raised portion;
• further comprising a reflector plate arranged between the light guide plate and the raised portion and an optic film assembly positioned on the light guide plate;
• and
• wherein the backlight source is bonded by thermal grease to the first mounting section.
