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. |
