Abstract
An LED area-light source module used for an LCD. A metal housing constituting a flat base, a bending portion, and at least one raised portion, in which the bending portion is an extension of the flat base and the overlapping portion between the bending portion and the flat base serves as a lying space. An LED circuit board is assembled into the lying space and has a plurality of chips, at least one connecting pad and at least one concave portion. An optical plate module is assembled on the flat base of the metal housing. At least one wire has one end welded on the connecting pad and the other end connected to a power supply. An edge between the exposed portion and the unexposed portion of the wire is installed on the bottom side of the concave portion.
Claims8
An LED area-light source module used in an LCD, comprising:
- a metal housing constituting a flat base, a bending portion, and at least one raised portion, in which the bending portion is an extension of the flat base and the overlapping portion between the bending portion and the flat base, serves as a lying space;
- an LED circuit board assembled into the lying space and comprising a plurality of chips, at least one connecting pad and at least one concave portion, in which the concave portion is formed at one rim of the LED circuit board and adjacent to the connecting pad, the concave portion constituting a bottom side and two sidewalls, and the bottom side is adjacent to the connecting pad;
- an optical plate module assembled on the flat base of the metal housing;
- a power supply;
- and
- at least one wire, in which one end of the wire is welded to the connecting pad and the other end of the wire is connected to the power supply;
- wherein, an edge between the exposed portion and the unexposed portion of the wire is installed on the bottom side of the concave portion.
