Abstract: An LED lamp structure with a heat sink includes a reflection cup, an LED module, and a cover, in addition to the heat sink. The reflection cup has an inside bottom surface, a reflection surface, an outside bottom surface, and a light exit. The LED module is thermally conductively and fixedly provided on the inside bottom surface. The cover covers the LED module. The heat sink is thermally conductively connected to the outside bottom surface. The LED lamp structure is efficient in not only light extraction but also heat dissipation.

Abstract: In an assembly of a heat dissipating module and a computer housing, the computer housing has an interior adapted for receiving an electronic component, and a housing fan. The heat dissipating module includes a heat sink base and a fan. The heat sink base is provided on the electronic component, and the fan is provided on the heat sink base. The heat sink base absorbs heat generated by the electronic component, and the hot air around the heat sink base is drawn in by the fan and discharged directly toward the housing fan, which in turn extracts the hot air out of the computer housing. Thus, hot air around the electronic component is not likely to stay within the computer housing, thereby maintaining a normal operating temperature within the computer housing.
