Patent ID: 7965023

Claim:
An LED lamp, comprising: a heat dissipation housing formed with a receiving hole axially passed therethrough, and a position of an upper end of the heat dissipation housing adjacent to the receiving hole being formed with an engaged indentation; an insulation housing made of insulation material, and the profile of the insulation housing capable of being installed into the receiving hole, an upper end of an outer periphery of the insulation housing radially extended to form a projection which is configured to be inserted and engaged into the engaged indentation in a case that the insulation housing is installed in the receiving hole; an electrode cap comprising a first electrode and a second electrode, wherein an edge of the electrode cap is connected to a lower end of the insulation housing, and wherein the electrode cap is extended out of a lower end of the heat dissipation housing in a case that the insulation housing is installed in the receiving hole and the projection is engaged with the engaged indentation; a power printed circuit board (PCB) received in the insulation housing, and electrically connected to the first and second electrodes, respectively; at least one LED, and an installation base plate having a first side provided with conductive circuits for installing the LED and being electrically connected to the power PCB, and a second side connected to the upper end of the heat dissipation housing.
