[0040] The utility model provides a plug-and-play driving power supply.

[0041] please Figure 1 、 Figure 2 and Figure 6 In one embodiment of the present invention, the plug-and-play driving power supply includes:

[0042] The outer shell 100 is used for being snap-connected to the lamp;

[0043] A power module 300 is disposed in the outer shell 100; and

[0044] The plug end 200 is disposed on the outer shell 100 and is electrically connected to the power module 300. The plug end 200 includes a first terminal group for electrically connecting to the mains power and a second terminal group for electrically connecting to the light source of the lamp.

[0045] The technical solution of the present utility model is to dispose a power module 300 and a plug terminal 200 within the outer shell 100. The power module 300 is electrically connected to the mains power supply and the light source of the lamp via the plug terminal 200, while the outer shell 100 is detachably connected to the lamp via a snap-fit ​​connection. In this way, users or maintenance personnel do not need to disassemble the lamp or perform complicated assembly and disassembly operations. They only need to control the snap-fit ​​connection between the outer shell 100 and the lamp, and can synchronize the electrical connection or disconnection between the power module 300 and the mains power supply and the light source. The driver power supply can be assembled and disassembled in a single operation, thereby reducing the number of assembly and disassembly steps and simplifying maintenance.

[0046] Among them, the corresponding plug-in terminal 200 on the lamp is provided with an adaptive docking terminal to ensure the stability of the driving power supply after being installed on the lamp. Correspondingly, the location on the lamp for the driving power supply to be plugged in can be the light-emitting side of the lamp, or the backlight side of the lamp, etc. It should be noted that the number of terminals of the first terminal group is configured according to the specifications of the mains electricity, such as two-phase or three-phase, and the terminals of the second terminal group are configured as positive terminals and negative terminals. In addition, the above-mentioned terminals can be male terminals or female terminals, and the corresponding terminal types on the lamp are adapted. It can be understood that the direction in which the plug-in terminal 200 is connected to the docking end of the lamp is parallel or nearly parallel to the clamping direction of the outer shell 100, so that when the driving power supply is disassembled and assembled in one direction of the lamp, the plug-in terminal 200 can automatically connect and conduct with the corresponding docking end on the lamp, thereby simplifying the assembly operation of the driving power supply and improving the convenience of operation.

[0047] In one embodiment, please refer to Figures 1 to 3The plug-in end 200 includes a plug-in barrel 210, which contains a first terminal set and a second terminal set. The plug-in barrel 210 is designed to be plugged into the lamp. As will be appreciated, the integration of the first and second terminal sets within the plug-in barrel 210 greatly simplifies the connection process between the driver and the lamp. Users or maintenance personnel simply insert the plug-in barrel 210 into the corresponding connectors on the lamp to establish an electrical connection between the power module 300, the lamp's light source, and the mains power supply, eliminating the need for complex soldering or screwing operations. Similarly, when the driver fails and needs to be replaced, the terminal set integrated within the plug-in barrel 210 makes the replacement process even simpler. Users simply unplug the old driver and plug in the new one, eliminating the need to disassemble the lamp or perform complex connection operations, thereby reducing maintenance complexity and costs. Furthermore, the integration of the terminal set within the plug-in barrel 210 makes the entire driver more compact, occupying less space. This facilitates a more efficient layout within the limited space of the lamp, improving space utilization. Of course, in other embodiments, the first terminal group and the second terminal group may also be distributed inside and outside the plug barrel 210 .

[0048] Further, in this embodiment, please refer to Figures 1 to 3The connector barrel 210 is provided with multiple partitions 211, distributed along the circumference of the connector barrel 210 and extending radially. Adjacent partitions 211 form a plug-in slot 212, with a male terminal 214 from each of the first and second terminal groups disposed within one of the plug-in slots 212. It will be appreciated that the partitions 211 divide the interior of the connector barrel 210 into multiple independent plug-in slots 212, with each male terminal 214 housed within one of the plug-in slots 212. This design effectively isolates arcs between different male terminals 214, preventing arcs from spreading between them and thus reducing the risk of arc faults. If an arc fault occurs in a male terminal 214, the partitions 211 can limit the arc's spread, preventing it from affecting other terminals, thereby improving the safety of the entire connector barrel 210. Furthermore, the partitions 211 ensure that each male terminal 214 is accurately positioned within the plug-in slot 212. Through the guidance of the partition 211, the male terminal 214 can be smoothly inserted into the female terminal of the lamp, avoiding the difficulty or damage of plugging and unplugging due to inaccurate positioning. In addition, the partition 211 forms a certain support structure inside the plug-in barrel 210, which can enhance the force control during the plug-in and unplugging process. When performing plugging and unplugging operations, the partition 211 can limit the movement range of the terminal to prevent damage or loosening of the terminal due to excessive plug-in and unplugging force, and then after multiple plug-in and unplugging operations, the terminal can still maintain good electrical connection performance and mechanical stability. Of course, in other embodiments, the terminals of the first terminal group and the second terminal group can also be configured as female terminals, or the partition 211 is distributed radially, and the terminals of the first terminal group and the second terminal group are arranged in a ring shape to reduce the difficulty of alignment during the disassembly and assembly process of the driving power supply.

[0049] In one embodiment, please refer to Figures 1 to 3 The plug-in tube 210 also includes an anti-foolproof protrusion 213 provided on the inner wall, and the anti-foolproof protrusion 213 is adapted to be inserted into the anti-foolproof guide groove of the lamp. It can be understood that the design of the anti-foolproof protrusion 213 is to ensure that the plug-in tube 210 can only be inserted into the anti-foolproof guide groove of the lamp in the correct way. If the plug-in direction or position is incorrect, the anti-foolproof protrusion 213 will be blocked and cannot be inserted smoothly, thereby avoiding the occurrence of incorrect plug-in. In this way, it can ensure that the connection between the plug-in tube 210 and the lamp is accurate, reduce performance problems or safety hazards caused by improper plug-in, and improve the stability and reliability of the entire electrical system. At the same time, the anti-foolproof design makes the installation process simpler. Users or maintenance personnel do not need to worry about the plug-in direction or position. They only need to insert the plug-in tube 210 into the lamp in the correct direction, which reduces the difficulty and complexity of installation. Of course, in other embodiments, a directional guide groove can also be provided on the outer shell 100 to limit the plug-in and unplugging direction in the driving power supply.

[0050] In one embodiment, please refer to Figure 2 and Figure 4 The outer shell 100 includes a shell body 110 and a shell cover 120. The shell cover 120 is connected to the opening of the shell body 110. The shell cover 120 is provided with an open ring portion 121. The first terminal group and the second terminal group are exposed in the open ring portion 121. The open ring portion 121 is used to snap onto the lamp. It can be understood that the detachable design between the shell cover 120 and the shell body 110 makes it easy to disassemble the outer shell 100 when necessary, thereby facilitating the maintenance or replacement of the internal power module 300 and the plug-in end 200. Among them, the design of the shell cover 120 and the shell body 110 makes it easy to connect the two, usually by screw fixation, snap connection or other quick assembly methods. At the same time, the setting of the open ring portion 121 enables the first terminal group and the second terminal group to be directly exposed to the outside, which is convenient for plugging with the docking port of the lamp. The open ring portion 121 typically has a certain degree of elasticity and toughness, allowing it to securely engage the fixture's mounting area. This enhances the stability of the mounting and prevents loosening or dislodging due to vibration or external forces. Furthermore, the open ring portion 121 provides enhanced protection for the plug end 200, reducing the likelihood of foreign matter intruding therein, thereby improving the operational stability of the driver. Of course, in other embodiments, the plug end 200 may also be directly exposed outside the housing cover 120.

[0051] Further, in this embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 The circumferential wall of the open ring portion 121 is provided with a plurality of first latching protrusions 122, which are used to latch into corresponding first latching grooves of the lamp. It is understood that the provision of the first latching protrusions 122 enables the open ring portion 121 to be more securely latched into the first latching groove of the lamp. Furthermore, since the open ring portion 121 is adjacent to the plug end 200 and the first latching protrusions 122 are provided on the circumferential wall of the open ring portion 121, particularly the inner circumferential wall, the tight fit between the first latching protrusions 122 and the first latching grooves ensures a more reliable electrical connection between the plug end 200 and the lamp, thereby reducing the risk of performance degradation or failure due to poor contact. The first latching protrusions 122 can be directly plugged into the lamp, or they can be rotated after being plugged into a predetermined position to latch into the lamp. Of course, in other embodiments, a latching structure can also be provided on the shell body 110 for latching into the lamp.

[0052] In one embodiment, please refer to Figures 2 to 4The plug end 200 also includes a connection seat 215, the peripheral edge of which is folded to form a limiting flange 216. The limiting flange 216 is arranged on the inner side of the shell cover 120 around the outer periphery of the open ring portion 121. It can be understood that the limiting flange 216 can effectively fix the plug end 200 inside the outer shell 100, preventing the plug end 200 from shaking or shifting during assembly or use, ensuring a more reliable connection between the plug end 200 and the lamp, and reducing performance degradation or failure caused by unstable plugging. At the same time, the close fit between the limiting flange 216 and the inner side of the shell cover 120 also enhances the durability of the driving power supply. During long-term use, this close fit can reduce the loosening or damage of the plug end 200 due to vibration or external force, thereby extending the service life of the driving power supply. In particular, when the outer shell 100 rotates circumferentially relative to the plug end 200, the limiting flange 216 can restrict the movement of the plug end 200 in the axial and radial directions, thereby ensuring the stability of the relative rotation between the outer shell 100 and the plug end 200. Of course, in other embodiments, the first locking protrusion 122 can also be provided on the outer periphery of the open ring portion 121, and the outer periphery of the plug barrel 210 can slide against the inner periphery of the open ring portion 121.

[0053] Further, in this embodiment, please refer to Figure 4 and Figure 5 The outer periphery of the shell cover 120 is provided with a first limiting protrusion 124, and the shell body 110 is provided with a limiting groove 112 at the periphery of the opening, and the first limiting protrusion 124 is adapted to the limiting groove 112. It can be understood that the close fit between the first limiting protrusion 124 and the limiting groove 112 effectively limits the relative rotation between the shell cover 120 and the shell body 110, ensuring that the two can maintain a stable posture after connection, and the structural strength of the entire outer shell 100 is avoided. Loosening or damage to the connection caused by rotation is avoided. At the same time, by limiting relative rotation, the design of the first limiting protrusion 124 and the limiting groove 112 enhances the stability of the connection between the shell cover 120 and the shell body 110. In addition, the user or maintenance personnel only needs to align the shell cover 120 with the opening of the shell body 110 and then gently press to achieve a stable connection, making the assembly process of the shell cover 120 and the shell body 110 more convenient. In particular, with respect to the relative rotation of the outer shell 100 and the plug end 200 in the circumferential direction, the provision of the first limiting protrusion 124 and the limiting groove 112 ensures the stability of the relative rotation in the circumferential direction between the outer shell 100 and the plug end 200. Of course, in other embodiments, a groove may be provided on the outer circumference of the shell cover 120, and a protrusion may be provided on the inner circumference of the shell body 110, so that the relative rotation of the shell body 110 and the shell cover 120 is limited by the mutual cooperation of the protrusion and the groove.

[0054] In one embodiment, please refer to Figure 4 and Figure 5The outer periphery of the shell cover 120 is provided with a second latching protrusion 123, and the inner wall of the shell body 110 is provided with a second latching groove 111. The second latching protrusion 123 is axially latched in the second latching groove 111. It can be understood that, combined with the matching requirements of the first limiting protrusion 124 and the limiting groove 112, the axial latching of the second latching protrusion 123 in the second latching groove 111 enhances the latching stability between the shell cover 120 and the shell body 110, helping to ensure the overall structural stability and durability of the outer shell 100. At the same time, the design of the second latching protrusion 123 and the second latching groove 111 makes the assembly process of the shell cover 120 and the shell body 110 more convenient. The user or maintenance personnel only needs to align the shell cover 120 with the opening of the shell body 110 and gently press, and the second latching protrusion 123 will automatically latch into the second latching groove 111 without the need for additional fixing tools or steps. Furthermore, the specific shapes and dimensions of the second latching protrusion 123 and the second engaging groove 111 ensure that only correctly matched shell cover 120 and shell body 110 can be successfully assembled together, helping to prevent misassembly of the shell cover 120 and shell body 110. Without loss of generality, a guiding slope is also provided at the opening of the shell body 110 to guide the second latching protrusion 123 into the second engaging groove 111, thereby reducing the difficulty of engaging the shell cover 120 and shell body 110. Of course, in other embodiments, the shell cover 120 can also be connected to the shell body 110 by adhesive or screwing.

[0055] In one embodiment, please refer to Figures 1 to 3 The plug end 200 is fixed relative to the power module 300, and the plug end 200 and the power module 300 are rotatably connected relative to the outer shell 100. Referring to the outer shell 100 being connected to the lamp, in this embodiment, the driver power is connected by a screw-on method, so that the user can easily achieve the electrical connection control between the power module 300 and the mains power and the light source. In addition, the first latch 122 ensures a stable connection between the outer shell 100 and the lamp, and the screw-on method can stagger the axial plug-in and pull-out directions when the driver power is normally installed, further ensuring a reliable connection between the power module 300 and the mains power and the light source. In addition, the plug end 200 and the power module 300 are rotatably connected relative to the outer shell 100. This design allows for a certain angle adjustment as needed during the installation or use of the driver power, which helps to adapt to different installation environments and user needs. Of course, in other embodiments, the driver power can remain fixed as a whole and be connected to the lamp in an axial plug-in manner, or the first terminal group and the second terminal group can be configured as ring terminals and then connected to the lamp by a threaded connection.

[0056] Further, in this embodiment, please refer to Figure 3 and Figure 4The peripheral wall of the open ring portion 121 is provided with a second limiting protrusion 125, which is used to be limited to the arc-shaped limiting groove 112 corresponding to the lamp. It can be understood that when the outer shell 100 rotates relative to the plug end 200, the second limiting protrusion 125 will contact the end of the arc-shaped limiting groove 112 when reaching a predetermined position, thereby preventing further rotation. The cooperation between the second limiting protrusion 125 and the arc-shaped limiting groove 112 effectively limits the rotation range of the outer shell 100 relative to the lamp, thereby ensuring that the connection between the plug end 200 and the lamp is both tight and not excessive, avoiding damage or unstable connection caused by over-rotation. At the same time, the cooperation between the second stop protrusion 125 and the arcuate stop groove 112 also provides the user with a clear assembly instruction. When the user feels that the plug end 200 has been rotated into position, that is, the second stop protrusion 125 contacts the end of the arcuate stop groove 112, they can confirm that the plug end 200 has been correctly installed in the lamp. This design helps reduce assembly errors and improve assembly efficiency. Of course, in other embodiments, a rib can be provided in the portion before the first stop protrusion 122 engages with the predetermined position of the first stop groove to remind the user to engage the predetermined position and avoid damage due to over-rotation.

[0057] In one embodiment, please refer to Figure 2 、 Figure 5 and Figure 6 The inner circumferential wall of the shell body 110 is provided with a support step surface 113, the power module 300 is provided with a support plate 310, the plug end 200 is connected to the support plate 310, and the peripheral edge of the support plate 310 is slidably mounted on the support step surface 113. It can be understood that when the plug end 200 is installed on the outer shell 100, the support plate 310 will be mounted on the support step surface 113, thereby limiting the axial movement of the plug end 200. In other words, the support step surface 113 provides stable support for the plug end 200 in the axial direction. At the same time, although the support step surface 113 provides stable support and limitation in the radial and axial directions, it does not prevent the plug end 200 from rotating in the circumferential direction, so as to ensure that the driving power supply can be connected to the lamp by means of a screw buckle, thereby ensuring that the plug end 200 will not deviate or shake outward when subjected to external force, thereby ensuring a tight connection between the plug end 200 and the outer shell 100. Of course, in other embodiments, an annular guide rail or guide groove may be provided on the inner wall of the shell body 110 , and the outer periphery of the power module 300 or the plug end 200 is slidably connected to the guide rail or guide groove.

[0058] Further, in this embodiment, please refer to Figure 2 、 Figure 4 and Figure 5The support step surface 113 is provided with a retaining ring protrusion 114 projecting toward the housing cover 120. A snap-fit ​​flange 126 is provided on the periphery of the housing cover 120. The snap-fit ​​flange 126 and the support plate 310 are located on the outer and inner sides of the retaining ring protrusion 114, respectively. It will be appreciated that the retaining ring protrusion 114 creates a gap between the outer periphery of the support plate 310 and the inner wall of the housing body 110. Furthermore, the snap-fit ​​flange 126 and the support plate 310 are located on the outer and inner sides of the retaining ring protrusion 114, respectively. This prevents the housing cover 120 from hindering the rotation of the power module 300 and the plug connector 200 relative to the housing body 100, thereby reducing resistance during assembly and enabling smoother rotation of the plug connector 200. At the same time, the limiting ring protrusion 114 also provides a stable limit for the circumferential rotation of the plug end 200 relative to the outer shell 100. During the rotation of the plug end 200 relative to the outer shell 100, the support plate 310 can be prevented from moving radially, thereby improving the stability of the outer shell 100 during the rotation relative to the plug end 200. Of course, in other embodiments, the inner wall of the shell body 110 can also be provided with a spacer ring, and in the axial direction of the shell body 110, the support plate 310 and the engaging flange 126 are respectively provided on opposite sides of the spacer ring to prevent rotational interference between the support plate 310 and the engaging flange 126.

[0059] In one embodiment, please refer to Figure 5 and Figure 6 The support step surface 113 is provided with a third limiting protrusion 116, and the outer periphery of the support plate 310 is provided with a limiting arc groove 311. The third limiting protrusion 116 is provided in the limiting arc groove 311, and the movement of the third limiting protrusion 116 is limited by the limiting arc groove 311. It can be understood that the coordinated design of the third limiting protrusion 116 and the limiting arc groove 311 can accurately control the circumferential rotation range of the plug end 200 relative to the outer shell 100. During the process of the plug end 200 rotating relative to the outer shell 100, the third limiting protrusion 116 will slide within the limiting arc groove 311 until it reaches the end or starting point of the limiting arc groove 311, thereby ensuring that the plug end 200 can stay within the predetermined rotation angle range. At the same time, when the third limiting protrusion 116 slides within the limiting arc groove 311 and reaches the end or starting point, it provides the user with a clear rotation indication, helping the user to determine whether the plug end 200 has been correctly installed on the outer shell 100 or whether further adjustment of the rotation angle is required. Of course, in other embodiments, the limiting arc groove 311 can also be provided on the inner periphery of the outer shell 100, and correspondingly, the third limiting protrusion 116 can be provided on the outer periphery of the support plate 310 to limit the rotation range of the plug end 200 relative to the outer shell 100.

[0060] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 5Multiple heat dissipation ribs 115 are distributed around the outer periphery of the outer shell 100. It will be appreciated that the heat dissipation ribs 115 increase the heat dissipation area by adding additional surface area to the outer periphery of the outer shell 100, allowing more heat to be dissipated through the outer shell 100 into the surrounding environment. Without loss of generality, the even distribution of the heat dissipation ribs 115 on the outer shell 100 helps reduce local overheating, improves overall heat dissipation efficiency, and extends the product's service life. Furthermore, the heat dissipation ribs 115 also enhance the structural strength of the outer shell 100, ensuring protection for the power module 300.

[0061] In one embodiment, please refer to Figure 1 and Figure 2 , the plug end 200 protrudes from the outer shell 100 and is exposed outside the outer shell 100. It can be understood that the plug end 200 protruding from the outer shell 100 allows the user to intuitively see the position and shape of the plug end 200, thereby helping the user to quickly and accurately find the plug end 200 and align it with the socket or interface of the lamp. Similarly, the user does not need to perform complex operations or adjustments to find and align the plug end 200; the plug end 200 can be directly inserted into the socket or interface of the lamp. Of course, in other embodiments, the plug end 200 can also be recessed relative to the outer periphery of the outer shell 100 to form a groove shape.

[0062] In one embodiment, the power module 300 is also integrated with an intelligent control module (not shown), which is used to realize circuit control of the lamp. It should be noted that the intelligent control module can realize intelligent control of the lamp circuit, including functions such as switching, dimming, and color temperature adjustment. Users can remotely or locally control the working status of the lamp through smart terminal devices such as mobile phone APP and remote control to realize intelligent lighting. At the same time, when the lamp fails, the intelligent control module can detect and issue an alarm in time, making it easier for management personnel to perform maintenance and repairs. In this way, the intelligent control module can automatically adjust the brightness and color temperature of the lamp according to factors such as ambient light and personnel activities, avoiding unnecessary energy waste. For example, when a person leaves the room, the intelligent control module can automatically turn off or reduce the brightness of the lamp, thereby saving electricity. In addition, the intelligent control module usually has protection functions such as overvoltage, overcurrent, and short circuit, and can cut off the power supply in time when the lamp circuit is abnormal, preventing the occurrence of safety accidents such as fire.

All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
