The purpose of this utility model can reach by taking following technical scheme:
The LED that power line gateway watertightness is good, comprise surface-mounted integrated circuit, lamp body top, lamp body bottom, outlet interface and power cord connector, described surface-mounted integrated circuit is fixed on lamp body bottom, also comprise upper cover and water proof ring, the top of described lamp body bottom is provided with groove, water proof ring is placed in groove, lamp body top to cover on groove and is fixed on lamp body bottom by upper cover, power cord connector one end is connected with surface-mounted integrated circuit, described power cord connector comprises conical form housing, spacer, O-ring seal, tightening nut and connector lug, described conical form housing two ends are distributed with the gear teeth, one termination has connector lug, other end cover has connecting line, O-ring seal is enclosed within wiring, spacer is placed between conical form housing and O-ring seal, and be fixed on O-ring seal by tightening nut.
As the utility model patent preferred embodiment, heat transfer glue-line is provided with between described surface-mounted integrated circuit and lamp body bottom, insulating effect can be played on the one hand, prevent the electric current on surface-mounted integrated circuit from passing on lamp body bottom, on the other hand, heat on surface-mounted integrated circuit can be delivered on lamp body bottom by heat transfer layer, then dispel the heat through lamp body lower external face fin.
In order to prevent outlet interface from causing nut to get loose because of collision, protection dished cover being set at the outlet interface place of described lamp body bottom, and can screw being hidden, playing beauty function.
The utility model is further improved: described outlet interface comprises outlet interface nut, outlet interface pad, ring packing cushion rubber, outlet screw and packing ring, described outlet interface nut, outlet interface pad, ring packing cushion rubber, outlet screw and packing ring are connected in series successively, and be fixed on both sides, lamp body bottom by nut, by such mechanical connection, waterproof action can be played.
Compared with prior art, the utility model has the following advantages:
One, the utility model adopts upper cover to be fixed on lamp body bottom by lamp body top, avoid and with screw, lamp body top be directly connected with lamp body bottom and cause the destruction on lamp body top, groove is set in lamp body bottom simultaneously, and place water proof ring, lamp body top is made only to be subject to the uniform pressure of water proof ring, so not only can reduce the wearing and tearing on lamp body top, extend the life-span on lamp body top, also can play waterproof action.
Two, outlet interface of the present utility model and power cord connector thereof adopt mechanical type to connect, good waterproof performance, and this comprehensive mechanical proof mechanism of water design, makes the utility model patent be particularly suitable for outdoor installation.
