[specific embodiment]

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Seeing also Fig. 1 and Fig. 2, is a preferred embodiment of the utility model LED lamp, and its lamp body 100 comprises interconnective lampshade 1 and Lamp cup 2.

Described lampshade 1 is cylindrical, and the power supply circuits (not shown) is housed in it.The lateral wall of lampshade 1 one ends is provided with screw thread 10, is connected with the external socket (not shown) for the LED lamp.Be equipped with some air intake vents 12 on the lateral wall of lampshade 1 other end, extraneous cold wind can enter in the lamp body 100 from air intake vent 12.The lateral wall one end end of lampshade 1 stretches out and forms one prominently along 14, is provided with a plurality of installing holes 140 in prominent along 14, and so that lampshade 1 is connected with Lamp cup 2, described installing hole 140 is adjacent with air intake vent 12.

Please together consult Fig. 3 to Fig. 6, pcb board, LED 3 and radiator fan 4 are installed, wherein in the described Lamp cup 2, LED 3 is installed on the pcb board, and, LED 3 and radiator fan 4 all be contained in lampshade 1 in power supply circuits be electrically connected, be equiped with the lens (not shown) in LED 3 outsides.

Described Lamp cup 2 adopts the heat conductivility preferred metal to process, and adopts aluminium nickel plating in the present embodiment.End sunken end face in Lamp cup 2 forms a recessed district 22, and LED 3 is installed in the recessed district 22.In order to reduce the loss of heat transmission between the two, can in recessed district 22, spread materials such as heat-conducting glue, tin slurry or silver-colored slurry in advance, reinstall LED 3.22 bottom surfaces, recessed district in Lamp cup 2 are provided with a plurality of through holes 21, and the power supply circuits that the electric wire of pcb board passes in through hole 21 and the lampshade 1 are electrically connected.

Described Lamp cup 2 has some first heat radiation ribs 24, the described first heat radiation rib 24 is formed by the bottom extension in Lamp cup 2 recessed districts 22, the first heat radiation rib 24 shape is in the shape of a spiral arranged, and has gap 23 between the adjacent first heat radiation rib 24, and the hot gas that LED3 produces in the cup 100 can 23 discharges from the gap.The top of the described first heat radiation rib 24 is provided with installing hole 240, and described installing hole 240 can be dashed forward with lampshade 1 and be matched along the installing hole on 14 140, and Lamp cup 2 and lampshade 1 are combined.
