An LED projector lamp includes a heat sink base holding a light source at the bottom side thereof; radiation fins radially arranged around the heat sink base, each radiation fin having one or multiple light shades that surround the periphery of the heat sink base to prevent light leakage and access of flies and vermin to the inside of the heat sink base and increase heat dissipation surface area; and an electric connector affixed to the radiation fins at the top and electrically connected with the light source at the heat sink base.
