Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a power supply, an LED lamp provided with the power supply, and a lighting system provided with the LED lamp. Background Art

[0002] Most of the existing LED lamps are LED constant current loads, so they need constant current drive power modules to cooperate with the drive, and the drive power module usually needs to be provided with a shell to protect and fix it, that is, the existing power supply includes a shell and a drive power module, and the drive power module is installed in the shell; currently, the conventional fixing methods of the shell and the drive power module include the following two:

[0003] The first method is to set a through hole on the circuit board of the driving power module, set a connecting column matching the through hole in the shell, and then connect the driving power module to the connecting column after passing the screw through the through hole, so as to fix the driving power module in the shell. Although this fixing method is the most commonly used fixing method, and the connection stability and firmness between the shell and the driving power module are good, this fixing method has the disadvantages of complicated installation process, high cost and low production efficiency. In addition, when the screw is connected to the connecting column, the connecting hole on the connecting column is synchronously tapped through the screw thread on the screw itself, which results in that when the screw and the connecting column are repeatedly disassembled and / or the screw is installed to the axis of the relative connecting hole, the connecting column is seriously worn, thereby greatly reducing the service life of the shell, and after the screw and the connecting column are repeatedly disassembled and assembled, the firmness of the connection between the driving power module and the shell will be seriously affected;

[0004] The second method is to fix the driving power module and the shell by gluing. Although this fixing method is simple to operate, the firmness of the connection between the shell and the driving power module depends on the performance of the glue, and the glue will be corrosive to the driving power module, affecting the performance and life of the driving power module. Furthermore, this fixing method will make the shell and the driving power module non-disassembled.

[0005] In this regard, Figure 1 and Figure 2As shown, an existing new type of power supply 9 solves the above problems better. The power supply 9 includes a shell 91 and a driving power module 92, wherein the shell 91 includes a box body 911 and a cover body 912. The box body 911 has a accommodating cavity, and a first snap-fit ​​structure is provided in the accommodating cavity; a second snap-fit ​​structure 9121 is provided on the cover body 912, and the second snap-fit ​​structure 9121 is detachably snap-fitted with the first snap-fit ​​structure, and the cover body 912 covers the opening of the accommodating cavity; in addition, a support block 9122, a limit block 9123 and an elastic snap buckle 9124 are also provided on the cover body 912, and the support block 9122, the limit block 9123 and the elastic snap buckle 9124 cooperate to form a snap position, and the circuit board 921 of the driving power module 92 is installed in the snap position. Compared with the conventional fixing method, the fixing method of the shell 91 and the driving power module 92 of the new power supply 9 has the following advantages:

[0006] First, there is no need to set additional screws to connect the housing 91 and the driving power module 92, which simplifies the installation process, reduces production costs, improves production efficiency, and does not cause damage to the housing, thereby better extending the service life of the housing;

[0007] Second, there is no need to glue the outer shell 91 and the driving power module 92 , thereby ensuring the performance and service life of the driving power module 92 , and the outer shell 91 and the driving power module 92 can be disassembled and assembled.

[0008] However, the novel power supply 9 still has the following disadvantages:

[0009] First, the design of the elastic buckle 9124 on the cover 912 will increase the structural complexity of the cover 912 and greatly increase the processing difficulty and processing cost of the cover 912;

[0010] Second, when disassembling the outer shell and the power supply 9, it is necessary to first disassemble the box body 911 and the cover body 912, and then pull the multiple elastic buckles 9124 on the cover body 912 to pry the circuit board 921 of the driving power module 92 out of the snap position, making the disassembly between the driving power module 92 and the cover body 912 troublesome and difficult, and the circuit board 921 of the driving power module 92 is easily damaged. Summary of the invention

[0011] In order to solve the above problems, the main purpose of the utility model is to provide a power supply with simple assembly and low production cost.

[0012] Another object of the utility model is to provide an LED lamp equipped with the above power supply.

[0013] Another object of the present invention is to provide a lighting system equipped with the above-mentioned LED lamp.

[0014] In order to achieve the main purpose of the utility model, the utility model provides a power supply, including a shell and a driving power module, the shell includes a box body and a cover body, the box body has a accommodating cavity, the cover body covers the opening of the accommodating cavity and is detachably connected to the box body, the driving power module is located in the accommodating cavity, wherein more than two first supporting bone positions are provided in the accommodating cavity, the first supporting bone positions have a first main body, a first positioning portion and a second positioning portion, a placement position is formed between the more than two first supporting bone positions, the circuit board of the driving power module is located in the placement position, the first positioning portion limits the movement of the circuit board in the length direction of the shell, and the second positioning portion limits the movement of the circuit board in the width direction of the shell; more than two pressing bone positions are provided on the cover body, the pressing bone positions are pressed on the first surface of the circuit board and cooperate with the first main body to limit the movement of the circuit board in the height direction of the shell.

[0015] As can be seen from the above, through the design of the power supply, when the outer shell and the driving power module are assembled, only the first supporting bone position on the box body and the press-fit bone position on the cover body need to cooperate to achieve the clamping of the circuit board of the driving power module, so that there is no need to set screws to fix the circuit board, which protects the box body or the cover body, extends the service life of the outer shell, simplifies the assembly process, improves the assembly efficiency and reduces the production cost; there is no need to glue the outer shell and the driving power module, avoids damage to the driving power module, ensures the stability and reliability of the driving power module, and realizes the detachable connection between the driving power module and the outer shell; furthermore, there is no need to set an elastic buckle on the cover body or the box body, which simplifies the structure of the cover body, reduces the production difficulty and production cost of the outer shell, and when the driving power module needs to be disassembled, it is only necessary to disassemble the box body and the cover body to take out the driving power module without further disassembly of the driving power module.

[0016] A preferred solution is that the number of the first supporting bone positions is two, and the two first supporting bone positions are located at a pair of diagonal corners of the circuit board.

[0020] Another preferred solution is that the box body is provided with a wire threading groove, which passes through the side wall of the box body; the cover body is provided with a wire crimping terminal matching the wire threading groove, the wire crimping terminal is inserted into the wire threading groove, and a wiring channel is formed between the wire crimping terminal and the wire threading groove.

At the same time, the wire crimping terminals arranged on the cover cooperate with the wire groove to properly clamp and fix the cables to prevent the cables from being pulled away from the circuit board of the driving power module and to avoid crushing the cables.

[0022] A further solution is that a third supporting frame is provided between the crimping terminal and the cover body.

[0023] As can be seen from the above, the third support bone position is used to increase the strength of the crimping terminal to prevent the crimping terminal from being excessively deformed or broken due to force.

[0024] Another preferred solution is that the box body is further provided with a connecting ear, and the connecting ear has a slot hole penetrating the connecting ear in the height direction.

[0044] Power supply embodiment

[0045] Reference Figure 3 and Figure 4 The power supply 100 includes a housing 1 and a driving power module 2. The housing 1 includes a box body 11 and a cover body 12. The box body 11 has a receiving cavity 111. The cover body 12 is detachably connected to the box body 11, and the cover body 12 covers the opening of the receiving cavity 111. The driving power module 2 is located in the receiving cavity 111 and is detachably connected to the housing 1.

[0046] Combination Figure 5 and Figure 6 , a first buckle part 112 is provided in the accommodating cavity 111 of the box body 11, and correspondingly, a second buckle part 1211 is provided on the cover body 12, and the second buckle part 1211 is matched with the first buckle part 112, so that the first buckle part 112 can be detachably buckled with the second buckle part 1211 to realize the disassembly and assembly between the box body 11 and the cover body 12. Preferably, one of the first buckle part 112 and the second buckle part 1211 is a buckle structure, and the other is a slot structure; as in the present embodiment, the first buckle part 112 is a buckle structure, which extends from the inner cavity wall of the accommodating cavity 111 to the cover body 12, and a bone guide wall 121 is formed on the cover body 12, and the second buckle part 1211 is formed on the bone guide wall 121, and the second buckle part 1211 is a slot structure. The design of the first buckling portion 112 and the second buckling portion 1211 makes it easier to disassemble the box body 11 and the cover body 12, thereby improving the efficiency of disassembling the box body 11 and the cover body 12.

[0047] In addition, more than two first support bone positions 113 are provided in the accommodating cavity 111. The first support bone position 113 has a first main body 1131, a first positioning portion 1132 and a second positioning portion 1133, and a placement position is formed between the more than two first support bone positions 113. The circuit board 21 of the driving power module 2 is located in the placement position, so that the first positioning portion 1132 limits the movement of the circuit board 21 in the length direction X of the outer shell 1, and the second positioning portion 1133 limits the movement of the circuit board 21 in the width direction Y of the outer shell 1.

[0048] Preferably, there are two first support bone positions 113, and the two first support bone positions 113 are located at a pair of diagonal corners of the circuit board 21. By designing the number and position of the first support bone positions 113, the structure of the box body 11 is simplified to the greatest extent while ensuring reliable fixation of the power supply 100 drive module, thereby reducing the production difficulty and production cost of the box body 11.

[0049] Of course, as other optional schemes, in other embodiments, the number of the first support bone positions 113 can also be four, and the four first support bone positions 113 are distributed at the four corners of the circuit board 21; although this design can enhance the supporting strength of the circuit board 21, it will greatly increase the structural complexity of the box body 11, thereby increasing the processing difficulty and processing cost of the box body 11. In this regard, as an alternative solution, at least one second support bone position 114 is added in the accommodating cavity 111 of the box body 11; wherein the second support bone position 114 has a second main body 1141 and a third positioning portion 1142, and in the height direction Z of the shell 1, the top of the second main body 1141 is at the same horizontal position as the top of the first main body 1131, so that the first main body 1131 and the second main body 1141 can cooperate with each other to stably and reliably support the second surface of the circuit board 21 in the height direction Z; the third positioning portion 1142 is adjacent to the side of the circuit board 21, and the third positioning portion 1142 can limit the movement of the circuit board 21 in the length direction X or the width direction Y; for example, in this embodiment, the number of the second support bone positions 114 is two, and the two second support bone positions 114 are arranged close to the other pair of diagonals of the circuit board 21, and the third positioning portion 1142 limits the movement of the circuit board 21 in the width direction Y. It can be seen that the addition of the second support bone 114 to assist the first support bone 113 in supporting the circuit board 21 of the power supply 100 driving module can not only ensure the reliability and stability of the support for the circuit board 21, but also avoid deformation of the circuit board 21 due to insufficient support strength; in addition, since the structure of the second support bone 114 is simpler than that of the first support bone 113, the structure of the box body 11 can be simpler than that of all support bones using the first support bone 113, so as to reduce the production difficulty and production cost of the box body 11.

[0050] The cover body 12 is provided with more than two press-fitting bone positions 122, which are used to be pressed on the first surface of the circuit board 21 and cooperate with the first body 1131 to limit the movement of the circuit board 21 in the height direction Z. As in the present embodiment, the number of the press-fitting bone positions 122 is preferably four, and the four press-fitting bone positions 122 are preferably designed close to the four corners of the circuit board 21. This design can not only ensure the support and fixing strength of the circuit board 21, but also simplify the structure of the cover body 12, which is conducive to reducing the production difficulty and production cost of the cover body 12.

[0051] Combination Figures 7 to 9, the box body 11 is also provided with a threading groove 115, a connecting ear 116, a heat dissipation groove 117 and an operation notch 118. The threading groove 115 runs through the side wall of the box body 11, and the threading groove 115 is used for routing the cables connected to the driving power module 2; preferably, the cover body 12 is provided with a crimping terminal 123 matching the threading groove 115. When the cover body 12 and the box body 11 are assembled, the crimping terminal 123 is inserted into the threading groove 115, and a routing channel 1151 is formed between the crimping terminal 123 and the threading groove 115. The crimping terminal 123 is used to cooperate with the threading groove 115 to properly press and fix the cable, prevent the cable from being pulled away from the circuit board 21, and avoid crushing the cable. Furthermore, a third support bone position 1231 is provided between the crimping terminal 123 and the cover body 12, and the third support bone position 1231 is used to increase the strength of the crimping terminal 123 to prevent the crimping terminal 123 from being excessively deformed or broken due to force. The setting of the operating notch 118 allows the user to pry the operating notch 118 with fingers or tools when disassembling the box body 11 and the cover body 12, and then force the first snap-fitting portion 112 and the second snap-fitting portion 1211 on the same side of the operating notch 118 to disengage from each other through the operating notch 118, making the disassembly between the box body 11 and the cover body 12 simpler and easier to operate.

[0052] The connecting ear 116 has a slot 1161 that penetrates the connecting ear 116 in the height direction Z. The connecting ear 116 is used to connect with an external component so that the box body 11 can be firmly connected with the external component and the box body 11 and the external component can be assembled more conveniently. The heat dissipation groove 117 penetrates the side wall of the box body 11. The heat dissipation groove 117 is used to conduct the heat generated by the driving power module 2 so that the driving power module 2 can work stably.

[0053] The following briefly describes the assembly steps of the power supply 100:

[0054] When assembling the power supply 100, first, invert the housing 1 so that the opening of the accommodating cavity 111 faces upward. Next, invert the driving power module 2 in the placement position so that the main components on the driving power module 2 are located between the bottom of the accommodating cavity 111 and the circuit board 21, and the second groove 212 of the circuit board 21 is engaged with the first support bone position 113, and the third groove 213 is engaged with the second support bone position 114, so as to restrict the circuit board 21 in the placement position and prevent the circuit board 21 from moving in the length direction X and the width direction Y.

[0055] Next, the cover body 12 is covered on the opening of the accommodating cavity 111, and the second snap-fitting portion 1211 is snap-fitted and connected with the first snap-fitting portion 112. During the assembly process of the second snap-fitting portion 1211 and the first snap-fitting portion 112, the first snap-fitting portion 112 pushes the guide bone wall 121 to elastically deform toward the middle of the accommodating cavity 111. When the first snap-fitting portion 112 (snap-fit ​​structure) moves to the second snap-fitting portion 1211 (slot structure), the guide bone wall 121 returns to its original shape and abuts against the inner cavity wall of the accommodating cavity 111, so that the first snap-fitting portion 112 and the second snap-fitting portion 1211 are tightly snapped together, and the pressing bone position 122 is pressed onto the second surface of the circuit board 21 (or snap-fitted into the first groove 211 on the second surface), thereby cooperating with the first supporting bone position 113 and the second supporting bone position 114 to clamp and fix the circuit board 21.

[0056] In summary, it can be seen that through the design of the power supply 100, when the shell 1 and the driving power module 2 are assembled, only the first supporting bone position 113 on the box body 11 and the pressing bone position 122 on the cover body 12 need to cooperate to achieve the clamping of the circuit board 21 of the driving power module 2, so that there is no need to set screws to fix the circuit board 21, which protects the box body 11 or the cover body 12, extends the service life of the shell 1, simplifies the assembly process, improves the assembly efficiency and reduces the production cost; there is no need to glue the shell 1 and the driving power module 2, avoids damage to the driving power module 2, ensures the stability and reliability of the driving power module 2, and realizes the detachable connection between the driving power module 2 and the shell 1; furthermore, there is no need to set an elastic buckle on the cover body 12 or the box body 11, simplifies the structure of the cover body 12, reduces the production difficulty and production cost of the shell 1, and when the driving power module 2 needs to be disassembled, it is only necessary to disassemble the box body 11 and the cover body 12 to take out the driving power module 2, without the need to further disassemble the driving power module 2.

[0057] LED lamp embodiment

The LED light source is electrically connected to the driving power module of the power supply. The driving power module is used to provide a stable current and voltage for the LED light source to protect the LED light source and enable the LED light source to work stably. At the same time, the driving power module is also used to control the LED light source to illuminate according to the set mode. By setting the above power supply, the LED lamp makes its production and assembly simpler, which is conducive to improving assembly efficiency and reducing production costs.

[0059] Lighting system embodiment

[0060] The lighting system includes a control terminal and the LED lamp described in the above LED lamp embodiment, and the LED lamp also includes a driving power module, and the driving power module is electrically connected to the light source. The LED lamp is electrically connected to the control terminal through the driving power module and / or the LED lamp exchanges information with the control terminal through the driving power module. Among them, the control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the driving power module of the LED lamp. When the control terminal is an intelligent control panel or a remote control, a first wireless communication module is provided on the driving power module, and a second wireless communication module is provided on the control terminal; the control terminal is electrically connected to the driving power module, and / or the first wireless communication module exchanges information with the second wireless communication module. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearing device, etc.), and can also be an artificial intelligence robot. It can be seen that the lighting system is provided with the above LED lamp, so that its use cost is lower and it is conducive to the installation and maintenance of the lighting system.
