Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In this application, the terms "comprises" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0035] See also Figures 1 to 8 An embodiment of the present application provides a splicing structure of an LED lamp, the LED lamp includes a lamp housing 100 and a light-emitting component 160 arranged inside the lamp housing 100, the splicing structure includes two lamp housings 100 (for ease of distinction, the two lamp housings are respectively a first lamp housing 110 and a second lamp housing 120) and a connector 130, the two lamp housings have a first end surface 111 and a second end surface 121 arranged opposite to each other (for ease of understanding, in this embodiment, the first lamp housing 110 has a first end surface 111, and the second lamp housing 120 has a second end surface 121), the first end surface 111 and the second end surface 121 are respectively provided with a first slot 112 and a second slot 122, the connector 130 has a first plug-in portion 131 and a second plug-in portion 132 respectively matched with the first slot 112 and the second slot 122, and in a spliced ​​state, the first end surface 111 and the second end surface 121 are basically in contact with each other.

[0036] After the first lamp housing 110 and the second lamp housing 120 are connected by the connecting piece 130, the first end face 111 and the second end face 121 are basically abutted against each other, and the first slot 112, the second slot 122 and the connecting piece 130 are all hidden in the two lamp housings. Compared with the existing technology in which the connection is exposed, the overall appearance is more beautiful and the structural strength is improved.

[0037] See also Figure 5 to Figure 7bThe lamp housing 100 includes a bracket 101 formed of a profile, a lampshade (not shown in the figure) snap-fitted with the bracket 101, and plugs 140 arranged at both ends of the bracket 101, and slots are arranged on the plugs 140. The plugs 140 at both ends of the bracket 101 are respectively a first plug 141 and a second plug 142, the first slot 112 is arranged on the first plug 141, and the second slot 122 is arranged on the second plug 142. Therefore, when the first lamp housing 110 and the second lamp housing 120 are spliced ​​with each other, the connecting member 130 can cooperate with the first plug 141 of the first lamp housing 110 and the second plug 142 of the second lamp housing 120 (or can cooperate with the second plug 142 of the first lamp housing 110 and the first plug 141 of the second lamp housing 120). In this embodiment, the end face of the plug 140 is flush with the bracket 101, and the profile is preferably an aluminum profile. Furthermore, the connector 130 has pins for electrically connecting two LED lamps. Preferably, the first slot 112 and the second slot 122 are also provided with pins.

[0038] In order to facilitate the connection of the connecting member 130 (ie, to distinguish the first plug-in portion 131 from the second plug-in portion 132 ), the first plug-in portion 131 is radially smaller than the second plug-in portion 132 .

[0039] Furthermore, the bracket 101 includes two oppositely arranged side walls 102 and a first partition 103 and a second partition 104 arranged between the two side walls 102. The first partition 103, the second partition 104 and the two side walls 102 form a cavity 105 with openings at both ends. The plug 140 is arranged at both ends of the cavity 105 (this design can avoid the light emitted by the light-emitting component being blocked by the plug 140 when the light-emitting component is working. When the plugs 140 of the two lamp housings 100 are spliced, the spliced ​​joint can also be illuminated by light and no shadow will appear). In this embodiment, screw holes corresponding to the plug 140 are arranged on the first partition 103 and the second partition 104, that is, the plug 140 is fixedly connected to the bracket 101 by screws.

[0040] Furthermore, the first partition 103 is arranged relative to the lampshade, and is used to fix and install the light-emitting assembly 160. The light-emitting assembly 160 includes a substrate 162 and an LED lamp bead 163 arranged on the substrate 162. In order to facilitate the installation of the substrate 162, a card slot 1031 that cooperates with the substrate 162 is arranged below the first partition 103 (to limit the axial movement of the substrate 162). In this embodiment, a driving power supply 180 electrically connected to the light-emitting assembly 160 is arranged inside the cavity 105. The light-emitting assembly 160 is separated from the driving power supply 180 by the first partition 103, making the circuit safer.

[0041] In this embodiment, due to the presence of the side wall 102, when the light emitting assembly 160 fixed on the first partition 103 is working, the lights on both sides will be blocked by the side wall 102. In order to improve the light emitting effect, reflectors 161 are provided on both sides of the light emitting assembly 160. The reflectors 161 are specifically located between the edge of the light emitting assembly 160 and the side wall 102 (see Figure 5 ).

[0042] See also Figure 1 to Figure 3 In order to prevent the two lamp housings 100 from loosening and coming off after being spliced, the present application further includes a reinforcing member 170 disposed at the connection of the two lamp housings 100 and fixedly connected to the two lamp housings 100. The reinforcing member 170 is fixedly disposed on the installation side of the LED lamp facing the support. In order to facilitate the installation of the reinforcing member 170, a guide groove 106 is disposed above the second partition 104. The reinforcing member 170 can be slidably installed in the guide groove 106. In order to flexibly adjust the position of the reinforcing member 170, a plurality of flat head screws are disposed on the reinforcing member 170. When fixing is required, the flat head screws are screwed downward until they are limited against the second partition 104. Preferably, the middle position of the reinforcing member 170 is located at the abutment between the first end face 111 and the second end face 121.

[0043] An embodiment of the present application also provides an LED lamp, including a lamp housing 100 and a light-emitting component 160 arranged in the lamp housing 100, the lamp housing 100 includes a bracket 101, a lampshade snap-fitted with the lampshade, and the above-mentioned plugs 140 arranged at both ends of the bracket 101, the bracket 101 is a profile, the end face of the plug 140 is flush with the bracket 101, and a slot is provided, the plug 140 is the plug 140 shown above, and its structure and installation method can be specifically referred to above.

[0044] In order to facilitate the transportation of the lamp housing 100 , the LED lamp includes a protection cover 200 disposed at the end of the lamp housing 100 .

[0045] See also Figure 2 to Figure 7b In order to facilitate the installation of the protective cover 200, in the present embodiment, the first partition 103 and the second partition 104 are respectively provided with notches 107 at both ends, and the plug 140 axially extends through the notch 107 to have a first extension portion 143 exceeding the first partition 103 and a second extension portion 144 exceeding the second partition 104. Correspondingly, the protective cover 200 is provided with a first hook 210 cooperating with the first extension portion 143 and a second hook 220 cooperating with the second extension portion 144. The first hook 210 is engaged with the first extension portion 143, and the second hook 220 is engaged with the second extension portion 144, thereby realizing a fixed connection between the protective cover 200 and the lamp housing 100.

[0046] The LED lamp of the present application is not limited to the splicing of two lamp shells, and the method described above can be used to splice multiple lamp shells. The specific number of splicing can be selected according to the adaptability of the needs. Of course, the plug can also be directly plugged into the external power supply to achieve electrical connection (see Figure 1 ).

[0047] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0048] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
