Patent ID: 8727584

Claim:
A LED (Light Emitting Diode) bulb structure, comprising: a base, wherein one end of the base is electrically connected to a power source, and the other end of the base is used for holding a LED light source; a plurality of fins disposed on a surface of the base; and a shell enclosing the fins, the shell comprising: a plurality of first heat-dissipation holes arranged around the shell and each of the fins is aligned with at least a corresponding one of the first heat-dissipation holes for allowing airflow entering the first heat-dissipation holes to directly pass through each of the fins corresponding to each of the first heat-dissipation holes; and a plurality of second heat-dissipation holes arranged around the shell and disposed above the first heat-dissipation holes for enabling the first heat-dissipation holes and the second heat-dissipation holes to conduct thermal convection.
