Abstract
Official abstract text for this publication.
The present invention provides a heat sink and a backlight module using the heat sink. The heat sink includes a first bottom plate, a first side plate formed on the first bottom plate, and a second bottom plate mounted on the first bottom plate. The first bottom plate and the first side plate are integrally formed together. The second bottom plate is fixed by screws to an end of the first bottom plate that is distant from the first side plate. The first bottom plate is made of aluminum extrusion material. The second bottom plate is made of aluminum sheet material. The bottom plate of the heat sink is formed through jointing so that a portion of the bottom plate is made of aluminum sheet material that has a small thickness to thereby reduce the amount of aluminum material used and thus facilitating cost control.
