Patent ID: 7543960

Claim:
A light-emitting diode (LED) assembly, comprising: a circuit board defining at least one through hole therein; at least one LED having a pair of threads extending outwardly from the at least one LED, the threads being electrically connected with the circuit board, and the at least one LED being arranged on a first side of the circuit board and confronting one end of the least one hole of the circuit board; a heat dissipation apparatus being arranged on a second side of the circuit board opposite to the first side of the circuit board and confronting an opposite end of the at least one hole; and thermal interface material filled in the at least one hole of the circuit board with one end at the first side of the circuit board attaching to the at least one LED directly and an opposite end at the second side of the circuit board attaching to the heat dissipation apparatus directly for conducting heat of the at least one LED to the heat dissipation apparatus directly, the thermal interface material comprising a composition of nano-material and macromolecular material.
