A LED LAMP

摘要

A led lamp includes a heat sink (3), a lamp plate (2) and a lamp head fixing holder (6), wherein the lamp plate (2) is directly fixed on the heat sink (3); the heat sink (3) is provided with a heat dissipation surface arranged around the peripheral surface thereof, an accommodation cavity (34) therein, and a support part (38) arranged on one end part thereof. The support part (38) is provided with an opening (35) that communicates with the accommodation cavity (34), and the opening (35) on the end part of the heat sink (3) is covered by the lamp plate (2). Because the lamp plate (2) is directly fixed on the heat sink (3), the heat from the lamp plate (2) escapes directly via the heat sink (3), thereby solving the problem of heat dissipation and reducing cost.
