An LED heat dissipation structure including: a heat sink, with a lug axially extended from an end of the heat sink, a hollow portion disposed inside the heat sink and axially extended to the lug, and a plurality of fins integrally extended from a peripheral side of the heat sink; and a support base, having an axial through hole sheathed on the lug of the heat sink, and an end of the support base abutting the support surface of the heat sink. A semiconductor light emitting module is tightly coupled onto a distal surface at an end of the lug for conducting generated heat to the heat sink, and a mirror mount is pressed against the semiconductor light emitting module and coupled to the support base. |

1. An LED heat dissipation structure, comprising:
a heat sink, integrally formed, and having a support surface disposed at an end of the heat sink, a lug axially extended from the support surface, a hollow portion disposed inside the heat sink and axially extended to the lug, and a plurality of fins integrally extended from a peripheral side of the heat sink; a support base, having an axial through hole sheathed on the lug of the heat sink, and an end of the support base abutting the support surface of the heat sink, wherein the lug has a length not smaller than the through hole of the support base, and a semiconductor light emitting module is tightly coupled onto a distal surface at an end of the lug, and a mirror mount is pressed against the semiconductor light emitting module and coupled to the support base; wherein the support base can be fixed onto an intermediate plate having a plurality of installation holes; and the support base is in a stair shape in an axial direction and has a stair surface, and the support base is passed through the installation hole of the intermediate plate, and the stair surface of the support base is abutted against the intermediate plate, and the other side of the intermediate plate is secured onto the support base by a nut to force the intermediate plate to press onto the stair surface tightly. |
