Abstract
An LED lamp includes a heat sink, a circuit board, a threaded rod, a support post, and a base. The circuit board is fixed to the heat sink. One end of the threaded rod is fixed to the heat sink, and the opposite end of the threaded rod is fixed to one end of the support post. An opposite end of the support post is fixed to the base. The threaded rod, the support post, and the base are made of heat dispersing material with good heat conductivity. Heat generated by the circuit board is transferred directly to the threaded rod, or is transferred via the heat sink to the threaded rod, and the support post and the base.
