The present invention will be further described by way of embodiments with reference to the accompanying drawings. 1 to 9 show a preferred embodiment of the present invention, a combined luminaire comprising a bracket 1 provided with a circuit board and a waterproof end cap 3, the bracket 1, the lamp body and the waterproof end cap 3 are sequentially connected The lamp body comprises two lamp modules 2 connected in series. 5 and 6 can clearly show the structure of the lamp module 2, the two ends of the lamp module 2 are respectively provided with a male connecting end 2a and a female connecting end 2b, and the male connecting end 2a is provided with a plug 2c having an elliptical cross-sectional shape. The plug 2c is provided with four oppositely disposed locking holes 21, the inner surface of the locking hole 21 is a conical curved surface; the female connecting end 2b is provided with a slot 2d having an elliptical cross section, and the female connecting end 2b is also open There are four connecting holes 23, and the male connecting end 2a and the female connecting end 2b of the adjacent lamp module 2 are connected by a connecting pin 4. The connecting pin 4 includes a pin head 41 and a pin body 42. The outer surface of the pin head 41 has a conical surface. The pin body 42 passes through the connecting hole 2 3 and the pin head 41 is placed in the locking hole 21. Preferably, the pin body 42 has an external thread, and the connecting hole 23 has an internal thread. FIG. 9 shows the structure of the connecting pin 4. The pin body 42 can be provided with an Allen key hole 43 as shown in FIG. The pin body 42 can be directly screwed into the connecting hole 23 without falling off, and no additional action is required to support the connecting pin 4. When disassembling, it is not necessary to completely disengage the connecting pin 4 from the connecting hole 23, as long as the connecting pin is loosened. 4, so that when the re-installation does not need to find the connecting pin 4, it is convenient to operate; at the same time, the threaded pre-tightening force of the connecting pin 4 and the connecting hole 23 makes the slot 2d firmly wrapped on the plug 2c, and the pin The tapered surface of the head 41 cooperates with the tapered surface of the locking hole 21 so that the plug 2c and the plug Description

The more tightly the groove 2d is pressed, the male connection end 2a is firmly coupled with the female connection end 2b. Alternatively, the pin body 42 is provided with an external thread, and the connecting hole 23 is a light hole. The auxiliary nut connection is also fastened during assembly. Only the nut needs to be unscrewed during disassembly. The heat dissipation ribs 25 and the heat dissipation grooves 26 may also be disposed on the lamp module 2, and the heat dissipation ribs 25 and the heat dissipation grooves 26 are equally spaced.

As a further solution, the male connecting end 2a is provided with a flange 2e, and the female connecting end 2b is provided with a retaining opening 2f. Preferably, the flange 2e and the retaining opening 2f are provided with a small interference fit. Still more preferably, the cross-sectional shape of the flange 2e and the stopper 2f is elliptical. The cooperation of the flange 2e and the stopper 2f improves the overall degree of protection of the present invention, and the elliptical section has a better anti-rotation effect.

In a further embodiment, the plug 2c is a thin-walled hollow structure, and the wall of the plug 2c is connected to the side wall 22a of the accommodating groove 22. The plug 2c is provided with four accommodating slots 22, and the accommodating slot 22 includes two side walls 22a and a bottom plate 22b. The locking holes 21 are disposed on the bottom plate 22b and penetrate the bottom plate 22b. Four slots are provided in the slot 2d. The boss 24 and the connecting hole 23 penetrate the boss 24, and the boss 24 is provided with two positioning faces 241. Figure 4 shows more clearly the assembly relationship when the male connector 2a and the female connector 2b of the adjacent lamp module 2 are connected by the connecting pin 4. The two positioning faces 241 of the boss 24 and the side wall 22a of the receiving slot 22 The fit further defines the connection of the male connection end 2a and the female connection end 2b, so that the fit is more stable.

In still another aspect, the bracket 1 is coupled to the male connector 2a of the lamp module 2, and the waterproof connector 3 is coupled to the female connector 2b of the lamp module 2. The structure of the waterproof end cap 3 is shown in Fig. 7, which has the same structure as the male connecting end 2a of the lamp module 2 in Figs. 5 and 6, and the same map 8 shows the structure of the bracket 8 having the Figs. The female connector 2b of the lamp module 2 has the same structure. This not only facilitates the maintenance of the bracket 8, but also makes the mold more convenient. The male connecting end 2a and the female connecting end 2b can be separately formed into a mold, and then spliced and formed with other molds, which is convenient and saves materials.

Figure 10 shows a variant of the lamp module 2, which differs from the lamp module 2 shown in Figures 5, 6 in that the plug 2c is provided with a relatively arranged locking hole 21, the female connecting end 2b being opened 1 connection hole 23. Instruction manual

Thus, when the female connecting end 2b and the male connecting end 2a are connected by the connecting pin 4, the pressure between the pin head 41 and the locking hole 21 is tighter, and the cooperation between the plug 2c and the slot 2d is more and more. close.

Figure 11 shows a further variant of the lamp module 2, which differs from the lamp module 2 shown in Figures 5 and 6 in that the plug 2c has a locking hole 21 open therein, the female connecting end 2b being opened 1 connection hole 23. This structure allows only one-way locking between the pin head 41 and the locking hole 21 when the adjacent lamp modules 2 are connected, so that the plug 2c and the slot 2d may be loosened in use.

Fig. 12 shows a further variant of the lamp module 2, which differs from the lamp module 2 shown in Figs. 5, 6 in that the plug 2c has three locking holes 21, and the female connector 2b has three Connection holes 23. The cross-sectional shape of the plug 2c, the slot 2d, the flange 2e, and the port 2f are both rectangular.

Figure 13 shows a further variant of the lamp module 2, which differs from the lamp module 2 shown in Figures 5 and 6 in that the plug 2c has five locking holes 21 open therein, the female connecting end 2b being opened 5 connection holes 23. The cross-sectional shapes of the plug 2c, the slot 2d, the flange 2e, and the port 2f are all circular.

When the invention is installed, it is only necessary to pass the pin body 41 of the connecting pin 4 through the connecting hole 23, then the plug 2c is butted against the slot 2d, and finally the pin head 42 is placed in the locking hole 21. In this way, the number of the lamp modules 2 can be selected according to the needs of different application scenarios, and the assembly is convenient.

The above description is only an explanation of the present invention, so that those skilled in the art can fully implement the present solution, but it is not intended to limit the present invention. Those skilled in the art can make the present embodiment as creative as needed after reading the present specification. Modifications to contributions, these are not creative changes. However, it is protected by patent law as long as it is within the scope of the claims of the present invention.
