An LED lamp bulb structure is disclosed, in which a lamp controller is installed inside a lamp head and the bottom surface of the lamp controller is fixed by an upper cover. At the bottom surface of the upper cover, a heat dispersing fin set, which has at least one heat conducting tube installed therein, and a lower cover are fixed. Furthermore, a bulb housing, which has a tray mounted therein, is screwed around the peripheral edge of the lower cover, and at the bottom of the tray, plural LED lamp sets corresponding to plural heat conducting tubes are outwardly extended. Therefore, the heat produced by the LED lamp sets can have a heat exchange through plural heat conducting tubes and the heat dispersing fin set for achieving a better heat dispersing effect and for more effectively dispersing the heat. |
