Embodiment Construction
[0035] The LED illuminating lamp of the present invention is as figure 1 As shown, it is mainly composed of three parts: the light source part, the heat sink and the power supply part, among which:
[0036] The heat sink is made of metal aluminum and consists of a solid heat sink base 5 and a plurality of fins 6 radially surrounding the heat sink base 5 for conducting the heat energy generated by the LED lighting to the surrounding air. The fins 6 of the radiator can be made into various shapes that are conducive to increasing the effective heat dissipation area of the radiator, such as Figure 5 The fork-shaped wings shown and the Figure 6 T-shaped wings shown.
[0037] The two end faces of the radiator base 5 are smooth planes, and two through grooves 51 for placing wires are longitudinally arranged on the radiator base 5, and two screw fixing holes 52 are respectively provided on the two end faces, as Figure 5 , Figure 6 shown.
[0038] The light source part is co...
