Above-described LED bulkhead lamp capable, the cross section that lampshade is installed bead is L shaped, its outer rim comprises sagging ring limit; Described waterproof apron is installed in the described ring limit, and the external diameter of waterproof apron is suitable with the internal diameter on ring limit.
Above-described LED bulkhead lamp capable, described power pack are the power packs of sealing, and the cable porch of power pack is equipped with the water-proof cable fixing head.
Above-described LED bulkhead lamp capable comprises radiator sealing clamp, waterproof pad and a plurality of mounting screw, and described power pack comprises bottom, and described bottom comprises screw hole; Described waterproof pad is installed between pressing plate and the radiator end face, and described pressing plate comprises cable through wires hole and a plurality of screw hole, and described waterproof pad comprises a plurality of screw holes; Described mounting screw passes bottom screw hole, bridge screw hole and waterproof pad screw hole, is screwed into the screwed hole of radiator end face, and bottom, pressing plate, waterproof pad and radiator are fixed together.
Above-described LED bulkhead lamp capable comprises a plurality of installation sleeves, and described installation sleeve is arranged in the top of pressing plate, and the middle part of pressing plate comprises the protruded stigma to upper process, and described cable through wires hole is opened in described protruded stigma; Described mounting screw passes the installation sleeve endoporus bottom, pressing plate, waterproof pad and radiator is fixed together.
Above-described LED bulkhead lamp capable comprises seal gasket, and described lampshade is fixed on the bottom of radiator through screw, and described seal gasket is installed between the bottom surface of end face and radiator of lampshade.
The utility model LED bulkhead lamp capable has dustproof and waterproof ability preferably, and simple in structure, cost is lower, and light source heat radiation is better, and can satisfy has the demand of protecting under the service condition of covering.

[specific embodiment]
To the embodiment of the utility model LED bulkhead lamp capable shown in Figure 7, comprise members such as power pack 1, heronsbill shape radiator 2, led light source 3, lampshade 4 at Fig. 1.
Power pack 1 is hermetic power pack, and power pack 1 comprises upper casing 101 and bottom 102.The cable porch of power pack upper casing 101 is equipped with water-proof cable fixing head 5, prevents that moisture and dust from getting into.
Lampshade 4 is fixed on the bottom of radiator 2 through screw 6, and seal gasket 11 is installed between the bottom surface of end face and radiator 2 of lampshade 4.
There is the installation bead 401 of evagination the lower end of lampshade 4, and the cross section that bead 401 is installed is L shaped, and its outer rim has sagging ring limit 401a.Waterproof apron 8 hoops in U-shaped cross section are in the periphery of lucite baffle plate 7, in the groove of the waterproof apron 8 in the insertion U-shaped cross section, edge of lucite baffle plate 7.
The sub-assembly of waterproof apron 8 and lucite baffle plate 7 be installed in said installation bead 401 below; Waterproof apron 7 is positioned at the week of ring limit 401a, and the external diameter of waterproof apron 7 is suitable with the internal diameter of ring limit 401a.
Hoop 9 is enclosed within the outside that lampshade is installed bead 401 and waterproof apron 8, the sub-assembly of lucite baffle plate 7 and waterproof apron 8 is fixed on the bottom of lampshade 4.The sealing that waterproof apron 8 is realized between lucite baffle plate 7 and the lampshade 4.The waterproof and dustproof structure of lampshade bottom is far away from led light source 3 distances, and the lampshade volume inside is big, and the area of dissipation of lampshade is very big, on the basis that guarantees excellent sealing, can guarantee the led light source efficiently radiates heat, improves the service life of led light source.The flat organic glass baffle plate is convenient to cleaning, keeps good light transmittance.
4 installation sleeves 14 are arranged in the top of pressing plate 15, and waterproof pad 10 is installed between pressing plate 15 and radiator 2 end faces.4 mounting screws 13 pass the screw hole of power pack bottom 102, the endoporus of installation sleeve 14, the screw hole of pressing plate 15 and the screw hole of waterproof pad 10, are screwed into the screwed hole of radiator 2 end faces.Power pack bottom 102, installation sleeve 14, pressing plate 15, waterproof pad 10 and radiator 2 are fixed together.Pressing plate 15 extruding waterproof pads 10 form the water proof and dust proof sealing at radiator 2 tops.
The protruded stigma 1501 of the oriented upper process in middle part of pressing plate 15, cable through wires hole 1502 is opened in protruded stigma 1501.Protruded stigma 1501 stops that dust and moisture get into cable through wires hole 1502.
The above embodiment of the utility model LED bulkhead lamp capable has dustproof and waterproof ability preferably, and simple in structure, cost is lower, and light source heat radiation is better, can reach the degree of protection of IP54, and satisfying has the protection requirements of covering under the service condition.
