[0039] like Figures 1 to 3 As shown, in the first aspect of the embodiment of the present application, a driving power supply 100 is provided. The driving power supply 100 includes a shell 10 and an electrical component 20. The shell 10 has a first side wall 11 and a second side wall 12 opposite to each other. The first side wall 11 is installed with a first terminal 13, a second terminal 14 and a plurality of first snap-on structures 15. The second side wall 12 is installed with a third terminal 16, a fourth terminal 17 and a plurality of second snap-on structures 18. The third terminal 16 is electrically connected to the first terminal 13, the fourth terminal 17 is electrically connected to the second terminal 14, and the plurality of second snap-on structures 18 are distributed along the axial direction of the shell 10. The electrical component 20 is installed in the shell 10. The electrical component 20 has an input terminal 21 and an output terminal 22. The third terminal 16 is electrically connected to the input terminal 21, and the fourth terminal 17 is electrically connected to the output terminal 22. As shown Figure 6 and Figure 7 As shown, when at least two driving power supplies 100 are assembled in parallel, between two adjacent driving power supplies 100, the multiple second snap-in structures 18 of one driving power supply 100 are connected one-to-one with the multiple first snap-in structures 15 of the other driving power supply 100, the third terminal 16 of one driving power supply 100 is plugged into the first terminal 13 of the other driving power supply 100, and the fourth terminal 17 of one driving power supply 100 is plugged into the second terminal 14 of the other driving power supply 100.

[0040] The driving power supply 100 provided in the present application is used to produce lamps. According to the overall power of the light source part of the lamps of different models, one driving power supply 100 or multiple driving power supplies 100 connected in parallel are selected to drive the light source part.

[0041] When the overall power of the light source part of the lamp required for lighting the scene is relatively small, only one driving power supply 100 is needed to drive the light source part. The light source part is electrically connected to the fourth terminal 17 of the driving power supply 100 to achieve conduction between the driving power supply 100 and the light source part.

[0042] When the overall power of the light source part of the lamp required for the lighting scene is large, multiple driving power supplies 100 are required to be connected in parallel to drive the light source part, so that the output power of the multiple driving power supplies 100 assembled in parallel can match the overall power of the light source part accordingly. At this time, between two adjacent driving power supplies 100, the first buckle structure 15 of one driving power supply 100 is connected to the second buckle structure 18 of the other driving power supply 100, so that the two adjacent driving power supplies 100 are installed in parallel. In addition, between two adjacent driving power supplies 100, the third terminal 16 of one driving power supply 100 is plugged into the first terminal 13 of the other driving power supply 100 to achieve electrical connection, and the fourth terminal 17 of one driving power supply 100 is plugged into the second terminal 14 of the other driving power supply 100 to achieve electrical connection, so that the two adjacent driving power supplies 100 are arranged in parallel. In this way, for the overall power of the light source part of different models of lamps, the user only needs to use the required number of driving power supplies 100 provided in the present application for parallel assembly, and the fourth terminal 17 of the last driving power supply 100 is electrically connected to the light source part, so that the overall output power of the driving power supply after parallel assembly can correspondingly match the overall power of the light source part, which is simple and convenient.

[0043] like Figure 1 and Figure 3 As shown, the second side wall 12 is provided with a receiving groove 121. Furthermore, the third terminal 16 is rotatably mounted on the second side wall 12 through a pin shaft, so that the third terminal 16 can be in one of two positions: received in the receiving groove 121, or extended out of the receiving groove 121. Among them, the first terminal 13 is a plug-in port adapted to be plugged in with the third terminal 16. When multiple driving power supplies 100 are used in parallel to drive the light source part, between two adjacent driving power supplies 100, the third terminal 16 of one driving power supply 100 is rotated to extend out of the receiving groove 121, so that the extended third terminal 16 can be plugged in with the first terminal 13 of another driving power supply 100, and the third terminal 16 is electrically connected to the first terminal 13. And so on, until the third terminal 16 of the last driving power supply 100 does not need to be plugged in with the first terminal 13 of other driving power supplies 100, therefore, the third terminal 16 of the last driving power supply 100 is received in the receiving groove 121.

[0044] When one driving power source 100 is used to drive the light source, the third terminal 16 of the driving power source 100 does not need to be plugged into the first terminal 13 of another driving power source 100. Therefore, the third terminal 16 of the driving power source 100 is received in the receiving groove 121.

[0045] like Figure 1As shown, the fourth terminal 17 is a conductive column protruding from the second side wall 12. Correspondingly, the second terminal 14 is a plug port adapted to be plugged in with the conductive column. Furthermore, the conductive column has elastic deformation capability, or the conductive column can be elastically retracted. In this way, when multiple driving power supplies 100 are used in parallel to drive the light source unit, between two adjacent driving power supplies 100, the conductive column is plugged into the corresponding second terminal 14. Since the first snap-fit ​​structure 15 and the second snap-fit ​​structure 18 are connected to each other, the conductive column is elastically retracted and deformed, so that the conductive column is in close contact with the second terminal 14, that is, the conductive column and the second terminal 14 are well conductive.

[0046] like Figure 3 As shown, the housing 10 includes a housing body 103, a first end housing 101 and a second end housing 102, wherein the first end housing 101 and the second end housing 102 are connected to both ends of the housing body 103, respectively. Figure 2 As shown, the first side wall 11 of the first end shell 101 is installed with a first terminal 13 and a first buckle structure 15. Figure 1 As shown, the second side wall 12 of the first end shell 101 is installed with a third terminal 16 and a second buckle structure 18. Figure 2 As shown, the first side wall 11 of the second end shell 102 is installed with a second terminal 14 and a first buckle structure 15. Figure 1 As shown, the second side wall 12 of the second end shell 102 is installed with a fourth terminal 17 and a second buckle structure 18 .

[0047] like Figure 2 As shown, the first buckle structure 15 is configured as a bayonet. Figure 4 and Figure 5 As shown, the second snap-fit ​​structure 18 includes two opposite hook parts 181, and the two hook parts 181 are both provided with barbs 1811, and the barbs 1811 of the two hook parts 181 are arranged away from each other. When multiple driving power supplies 100 are used in parallel to drive the light source part, the barbs 1811 of the two hook parts 181 are adapted to snap into the bayonet between two adjacent driving power supplies 100, so that the two adjacent driving power supplies 100 can be installed in parallel, and the installation process is convenient and quick.

[0048] like Figure 4 and Figure 5 As shown, the second buckle structure 18 also includes a bracket 182, a buckle cover 183 and a spring 184. The bracket 182 is installed in the housing 10. The two hooks 181 can be slidably installed on the bracket 182. The two ends of the spring 184 are respectively abutted against the two hooks 181. The buckle cover 183 is connected to the bracket 182 to limit the two hooks 181 and the spring 184 from being separated from the bracket 182. Figures 3 to 5As shown, the two hook portions 181 are further provided with a push portion 1812, and the housing 10 is provided with a first through hole 191 corresponding to the push portion 1812, and the push portion 1812 passes through the first through hole 191. Between two adjacent driving power supplies 100 installed in parallel, when it is necessary to disassemble and separate the two adjacent driving power supplies 100, it is only necessary to apply force to the two push portions 1812 of each second buckle structure 18, so that the two push portions 1812 move closer to each other and retract into the first through hole 191, compressing the spring 184, and driving the two barbs 1811 to disengage from the bayonet. Furthermore, the first terminal 13 and the third terminal 16 are plugged into each other, and the second terminal 14 and the fourth terminal 17 are also plugged into each other, so that when the two barbs 1811 are disengaged from the bayonet, as the housings 10 of the two adjacent driving power supplies 100 are separated from each other, the first terminal 13 and the third terminal 16, the second terminal 14 and the fourth terminal 17 are all disengaged, so that the two adjacent driving power supplies 100 can be easily, conveniently and quickly disassembled and separated. When the force on the two pushing parts 1812 is cancelled, the two hook parts 181 move away from each other under the elastic force of the spring 184 until they are reset.

[0049] like Figure 3 As shown, the first end shell 101 and the second end shell 102 both include a first shell 111 and a second shell 112, the first shell 111 and the second shell 112 are mutually covered and connected, and the shell body 103 is an extruded aluminum profile. The first terminal 13 and a part of the second buckle structure 18 are both installed in the first end shell 101; the second terminal 14, the fourth terminal 17 and another part of the second buckle structure 18 are all installed in the second end shell 102, wherein the connecting part of the fourth terminal 17 is fixedly connected to the second shell 112 of the second end shell 102, and the fourth terminal 17 passes through the second shell 112 of the second end shell 102; further, the barbs 1811 of each second buckle structure 18 pass through the corresponding second shell 112 respectively.

[0050] like Figure 3 As shown, the first shell 111 is provided with two opposite hook arms 113 on one side facing the shell body 103, and correspondingly, the outer walls at both ends of the shell body 103 are provided with hook portions 114 corresponding to the hook arms 113. Figure 3As shown, the second shell 112 is provided with a connecting plate 115 on one side facing the shell body 103, and the connecting plate 115 is inserted into the shell body 103 and locked with the shell body 103 by screws 30. After the first shell 111 and the second shell 112 are covered and connected with each other, the two hook arms 113 are respectively buckled with the two hook parts 114, and the connecting plate 115 is inserted into the shell body 103, and then the connecting plate 115 and the shell body 103 are locked by screws 30, so that the first end shell 101 and the second end shell 102 are respectively connected to the two ends of the shell body 103. That is to say, in the driving power supply 100 of the present application, the first end shell 101 and the second end shell 102 are respectively detachably connected to the two ends of the shell body 103.

[0051] like Figures 1 to 3 , Figure 6 , Figure 7 As shown, the first end shell 101 and the second end shell 102 are both provided with second through holes 192 corresponding to the bayonet one by one, the second through holes 192 are connected to the bayonet, and the barbs 1811 pass through the second through holes 192 when buckled in the bayonet. Between two adjacent driving power supplies 100 installed in parallel, when it is necessary to disassemble and separate the two adjacent driving power supplies 100, the two pushing parts 1812 are subjected to force to drive the two barbs 1811 to move. At this time, it can be clearly observed through the second through holes 192 whether the barbs 1811 are completely out of the bayonet. When the barbs 1811 are completely out of the bayonet, the housings 10 of the two adjacent driving power supplies 100 can be separated from each other. In addition, when there is a self-locking situation between the two hook portions 181 and the bracket 182, the force applied to the pushing portion 1812 cannot make the two hook portions 181 move closer to each other. At this time, the barb 1811 can be pushed and squeezed through the second through hole 192 to retract the barb 1811 into the second through hole 192 until it is disengaged from the latch, and then the shells 10 of the two adjacent driving power supplies 100 can be separated from each other.

[0052] like Figure 3 , Figure 6 , Figure 7 As shown, the driving power supply 100 further includes an input socket 41, which is mounted on the first end shell 101 or the second end shell 102, and the input socket 41 is exposed to be electrically connected to the power line 50 of the external power supply, and the input socket 41 is electrically connected to the input terminal 21. Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, the driving power supply 100 also includes a protective cover 42, and the protective cover 42 is installed on the first end shell 101 or the second end shell 102. When multiple driving power supplies 100 are used in parallel to drive the light source part, it is only necessary to use the input socket 41 of any one of the driving power supplies 100 to electrically connect with the power cord 50, and the input sockets 41 of the remaining driving power supplies 100 do not need to be used. At this time, the protective cover 42 is used to cover and protect the input socket 41, so as to prevent electric shock accidents and ensure safety.

[0053] In a second aspect of the embodiments of the present application, a lamp is provided, wherein the lamp comprises at least one driving power supply 100 as described above. Specifically, the lamp includes but is not limited to a track light.

[0054] When only one driving power supply 100 is needed to drive the light source of the track light, each second snap-fit ​​structure 18 of the driving power supply 100 is snap-fitted to the track of the track light so that the driving power supply 100 can be stably installed on the track, and the third terminal 16 is received in the receiving groove 121, and the fourth terminal 17 is electrically connected to the light source of the track light.

[0055] When multiple driving power supplies 100 are used in parallel to drive the light source part of the track light, after the driving power supplies 100 are installed in parallel, the second snap-in structures 18 of the last driving power supply 100 are snap-connected with the track of the track light so that the driving power supply 100 is installed stably on the track, and the third terminal 16 of the last driving power supply 100 is received in the receiving groove 121, and the fourth terminal 17 is electrically connected to the light source part of the track light.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
