Electric connector comprises protective cover 812, sealing ring 813, two groups of seal washers 817 and wires; protective cover 812 is arranged on metallic support sheet 815; sealing ring 813 is between protective cover 812 and metallic support sheet 815, and sealing ring 813 is for improving the IP barrier propterty between protective cover 812 and metallic support sheet 815.Two groups of seal washers 817 are between electrical interface 121 in the Connecting groups piece installing 12 of adjacent LED modules 9 and metallic support sheet 815 respectively, specifically the top of electrical interface 121 is provided with the notch placing seal washer 817, seal washer 817 is for improving the IP barrier propterty between electrical interface 121 and metallic support sheet 815, and sealing ring 813 and two groups of seal washers 817 ensure that the IP barrier propterty of all parts for being electrically connected on metallic support sheet 815 fully.The two ends of the wire in protective cover 812 are each passed through the energising interface 21 on the threading position connecting PCB board 2 in two groups of adjacent LED modules 9.Pcb board 2 on two groups of LED modules 9 can be electrically connected by the electric connector of this structure easily, and the Simultaneous Switching realizing all LED modules 9 controls.In protective cover 812, auxiliary line plate 8123 is also set, auxiliary line plate 8123 connects the pcb board 2 in adjacent LED modules 9 respectively by wire, supplementary module is expanded into by the auxiliary line plate 8123 in protective cover 812, indwelling goes out such as infrared induction, the light modulation of DALI Intelligent electrodeless, the interfaces such as PLC Intelligent electrodeless light modulation, timesharing is realized to facilitate the client needing to implement light fixture Long-distance Control, the Long-distance Control such as light modulation, due to the limitation of current pcb board 2 manufacture craft, some supplemental functionality cannot be installed, arbitrarily supplemental functionality can be installed by auxiliary line plate 8123, especially LED technology is maked rapid progress, can upgrade the functional module on pcb board 2 by the replacing of auxiliary line plate 8123 and adjustment and upgrade.Protective cover 812 lateral wall is provided with the installing plate 8121 be connected as a single entity with it; installing plate 8121 is provided with installing hole 8122; fixed screw 816 is installed fore-set 814, bolt 811 is fixed on fore-set 814 through installing hole 8122, and protective cover 812 is installed more firm.
Embodiment 5
LED lamp as shown in Fig. 2 and Figure 17, comprises connection bracket 101 and LED luminescence component 102, LED luminescence component 102 is connected in connection bracket 101.The structure of LED luminescence component 102 is identical with embodiment 1, and the present embodiment 5 and the difference of embodiment 1 are that the structure of connection bracket 101 is different with embodiment 1, and the position that connection bracket 101 is arranged on LED luminescence component 102 is also identical with embodiment 1.
Connection bracket 101 comprises standing part 1011 and coupled coupling part 1012, standing part 1011 is connecting plates, connecting plate is L-shaped, the bottom of connecting plate is fixed in Connecting groups piece installing, the top of connecting plate is provided with lanyard hole, coupling part 1012 is ropes, and rope bottom ties up to the lanyard hole place of connecting plate, by rope and connecting plate, LED luminescence component 102 is suspended in aerial use.
Above-mentioned 5 embodiments are only this patent preferably embodiment, the quantity of such as LED module 9 can increase arbitrarily, such as 3 groups, 4 groups, 5 groups, 6 groups etc., general within 30 groups, the LED module 9 of any increase is connected with adjacent LED module 9 by jockey 8, and link position 8 is all on LED luminescence component 102; Above-mentioned fixing piece and electric connector can also adopt other mode, as long as namely realize the electrical connection with pcb board 2 that is fixedly connected with of adjacent LED module 9.
