A lighting source radiation construction and a backlight module are provided. The lighting source radiation construction comprises: at least one carrying base (112), at least one light emitting diode encapsulation construction (111) and a radiation base (12). The light emitting diode encapsulation construction is electrically connected to the carrying base; the radiation base comprises a first carrying surface (121) and at least one second carrying surface (122), the height of the second carrying surface is lower than the height of the first carrying surface. The light emitting diode encapsulation construction is thermally connected to the first carrying surface of the radiation base, and the carrying base is positioned on the second carrying surface of the radiation base, so the light emitting diode encapsulation construction can conduct heat by the aid of good conduction and radiation property of the radiation base directly, so as to improve radiation efficiency and life time of the light emitting diode encapsulation construction relatively. |
