Patent ID: 8764251

Claim:
A heat dissipation structure for a light bulb assembly comprising: a holder including a socket and a receiving space defined within the socket to receive a circuit board, the socket including a first abutting portion formed on a peripheral side thereof and at least one first coupling portion arranged on a lateral side thereof; a heat dissipating cover including a first end abutted by the first abutting portion, a second end opposite to the first end, a through hole communicating the first end with the second end for the socket to penetrate through, and at least one cooling fin arranged around an outer peripheral side thereof; and a light seat including an outer wall penetrating into the through hole of the heat dissipating cover, a holding space defined within the outer wall for installing an LED light which is electrically connected to the circuit board, a second abutting portion formed on a peripheral side thereof and abutted by the second end of the heat dissipating cover, and at least one second coupling portion extended from the outer wall to insert into the through hole and couple with the at least one first coupling portion so that the holder, the heat dissipating cover, and the light seat are tightly coupled together.
