A heat-dissipating device for a back light source for a flat panel display includes at least one back light unit 11, a circuit board 12, and at least one heat-dissipating board 3. The back light unit 11 includes a lighting element and a thermally conductive portion connected thereto for absorbing heat generated by the lighting element. The circuit board 12 includes at least one assembling hole 121 and is electrically connected to the back light unit 11 to form a back light module 1. The heat-dissipating board 3 is mounted to a rear side of the back light module 1. The thermally conductive portion 114 of the back light unit is extended through the assembling hole 121 of the circuit 12 and directly in contact with the rear side of the heat-dissipating board, allowing the heat-dissipating board to absorb and thus dissipate the heat generated by the back light module. Heat-dissipating board 3 has fins 32 and may also be cooled with additional fans "b" (figure 5). |
