The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As shown in Figure 1, 2, the utility model LED lamp comprises a reflector 1, a light source face shield 2, a LED3, a pedestal 4, a base plate 5, a radiator 6, many pull bars 7, a mistake line screw rod 8, a driving box bottom 9, a power supply 10, a driving box loam cake 11 and hooks 12, be provided with the central through hole (not shown) in the middle of the described radiator 6, the two ends of described many pull bars 7 are provided with screw thread 71.

During assembling, described LED3 is fixed in pedestal 4, and described pedestal 4 is fixed in base plate 5; Described light source face shield 2 covers LED and is fixed in pedestal 4, and base plate 5 is fixed in described reflector 1 bottom, and described plurality of LED 3 is positioned at described reflector 1; Described many pull bars 7 are set around radiator 6 peripheries, and the screw thread 71 at pull bar 7 two ends is spirally connected respectively and is fixed in base plate 5 and driving box bottom 9, thereby so that radiator 6 be clamped and fixed between base plate 5 and the driving box bottom 9; Described driving box bottom 9 is fixedly connected with driving box loam cake 11, and described power supply 10 is fixed in described driving box bottom 9 and the driving box loam cake 11 formed spaces, and described hook 12 is fixed in driving box loam cake 11 upper ends; Described excessively line screw rod 8 passes the central through hole in the middle of the radiator 6, and an end passes base plate 5, the other end penetrates between driving box bottom 9 and the driving box loam cake 11, so, not only conveniently wear the electric wire (not shown), so that whole lamp body exposes without wire rod, can also be so that whole lamp body connects more firm.

As mentioned above, fix radiator 6 by employing pull bar 7 connecting bottom boards 5 with driving box bottom 9, thereby need not to offer screw at the two ends of radiator 6, also avoided radiator 6 to remove to connect miscellaneous part by the lock screw, so, just reduced the spoilage of radiator 6.

In the present embodiment, described pedestal 4 is triangular in shape, comprises a diapire 41 and two

side

42,43, and described LED3 is set to multiple-piece, is individually fixed on the two

side

42,43 of triangular base 4, and described pedestal 4 diapires 41 are fixed in base plate 5.Corresponding plurality of LED 3, described light source face shield 2 also is provided with a plurality of.In the present embodiment, described LED3 is provided with two 31,32, and described light source face shield 2 also is provided with two 21,22.Be multi-disc with the LED3ization full wafer, can disperse the heat of LED, and triangular base 4 also enlarged area of dissipation, thereby the utility model LED lamp integral heat sink is functional.

In the present embodiment, the utility model LED bulkhead lamp capable comprises that also one is arranged at the heat radiation pressing plate 13 between base plate 5 and the radiator 6, be arranged at blade fixed head 14 and backing plate between driving box bottom 9 and the radiator 6, described blade fixed head 14 is fixedly connected on driving box bottom 9 with backing plate, and described blade fixed head 14 is fixed in radiator 6 ends.
